Reality sets in

2021_08_21_> Would be really nice to see solar flux improve, but sunspot numbers continue to be/trend mediocre.  Either the predicted time scale is going to be longer or the magnitudes of activity lower.  Maybe both?   Peak at ssn 60?  That would be sad.  The optimistic projections would be nice to see again, but I expect to be long dead before that happens.   SSN today at  25.  Based on today’s reality, it time to repair the 80m antenna and that 15m/10m project is deprecated.

2021_12_26_> What a difference a few months make.  Too bad this didn’t show up in the week before the 10m contest.  Beginning to think there may be a bigger cycle than I would have ever expected.  A few more months of this would make the high bands worth experimenting.  Was expecting peaks well below 100ssn….hmmm.  From the site, [current graphic link].

ssn graph, dec 2021

ssn graph, dec 2021….Didn’t ever expect to see ssn over 140 this cycle, or even much over 80.



2022_01_04:  This last graph shows the current cycle is ahead of the modest predictions that I thought were over-optimistic.  The spike to 140+ SSN in mid December seems more like a much stronger cycle than the last, since the cycles usually ramp up quickly once they begin.  That will make fun high bands again, but given the wide range of predictions that missed, even the folks doing this full time might be scratching their heads.  Fun stuff.  Peaks above 200 ssn?  Hoooooweeeeee!  2023 might be the best radio condx I’ll ever live to see again.

2022_03_30: Well the SSN just keeps a-climbing.  Flux movin-on-up.  Curve in numbers is still much sooner, steeper, and stronger than anything I expected, and better than the middlin’ prediction that I thought would be a best case.   The last hurrah.  Sweeeeet.  Now I’m just hoping the polar flip and mini-nova catastrophe sorts are wrong. 🙂 🙂 🙂

2024 NC QSO Party and POTA

Last month we finally got a chance to take the radio for a spin to work the NC QSO party from a few parks.  A ‘few’ parks turned into two parks, but I did learn a few things.  The weather in my area turned out to be perfect for a nice ride to a couple of portable operating areas.  Comfortably cool temps and crystal clear skies.

I decided to approach the trip as an Out-and-Back.  Drove out to the first park with intent on making stops to set up the portable antennas at each location.  Had just barely enough time at the first stop to get set up before the 10am local start.  Then things quickly went sideways.

!st stop, Richmond county, Pota k-08010

The Station

Used a hitch mounted mast receptacle to hold the antenna mast, a 32 foot telescoping fiberglass pole.  The mast supported a 40m/20m trap dipole, which I probably damaged by breaking a partially corroded wire on one of the traps.  Ends were tied up on some of the nearby coniferous biological antenna supports.  The station itself is an Elecraft K3 powered by a 100ah LifePo4 battery, on trickle charge from a 100w solar panel on the vehicle roof rack.  All set up on back seat of the vehicle.  Parked in the shade because comfort is more important than charging the battery.  Location numero uno was at McKinney Lake State Fish Hatchery Pota k-8010, Richmond county NC.  Unfortunately no photos of either the station or other sites due to ‘plan divergence #2-Lost Phone!’.

Diverging from the plan

Maybe a bit over-ambitious.  The first event occurred when the antenna suddenly lost its nice low SWR on 40m.  It is a 40m/20m trap dipole that has been in use for a couple of years.  Made just a handful on 40m to start then moved to 20m.  The antenna was still OK on 20m.  Curious.  After a bit I dropped the antenna to try to debug the 40m issue and noticed the wire coming out of the trap to one 50m leg appeared corroded.  Wasted too much time fiddling with antenna instead of operating.  Wire corrosion plus over-vigorous installation Mistake #1.

1st Stop, Richmond county, Pota K-08010

After burning too much time at the first location, moved on to POTA#2.  Ate my lunch there an could not find phone.  Spot#1 was just 6 miles away, so retraced to POTA#1 to see if I had dropped it there.  No Joy.  Mistake#2

Decided to skip spot#3 and drove directly to spot#4, Lee State Game lands, Pota K-06920 in Lee county.  Set up the 40m EFHW, and had decent runs on both 20m and 40m.  Success!  Neither 10m nor 15m were delivering, so skipped any time there.  This had the sun beginning to fall below tree line, so packed up the kit and moved to spot#5.  No photos taken, still had not found phone.

Spot#5 turned out to be occupied, and no other locations in the pota had been scouted.  Mistake #3.  At this point I mostly bailed.  Parked the car at home in driveway for a handful of Q’s on a hasty 20m vertical(non pota).  Then ditched entirely for food.

Damaged goods:

The broken antenna is going to be replaced.  A functional backup will also be added to the travel list.  The real downside did not show up until later, when the logging computer quit taking a charge.  Very likely RF damaged.  Bleh.


What was pounded in again is that wasting time during the event is costly.  ALWAYS have a backup.   The “lost phone” was not lost but had slid down between seats inside an invisibility cloak. Found that at home by dialing the number.  Not knowing was rain on the parade.

  • Need to examine the locations as planned to have an alternate site ready.
  • Need a few dry runs setting up to get a hard figure on how much time is needed. Pota practice sessions!
  • Need to research better to determine transit times between sites.
  •  Use the firmer times to budget time on each site.
  • Be more flexible.
  • If something craps out, HAVE A PLAN B
  • If the ANTENNA craps out go DIRECTLY to the backup.  Do NOT fart around with the broken antenna, it can be dealt with later.
  • Plan on more CW.

Taking the time to activate LEE and RIC was worth the effort.  It should be feasible to easily activate four different counties/Potas as a portable in the 10 hour period.  More than that would require more research or an area with a higher concentration of Pota entities.  Travel time is an issue.  Operating from POTA entities was also worthwhile, and the first time scout of the sites was useful for future POTA activations.

W4KAZ IOTA M/S 2023 with N4YDU from NA-067, Cape Lookout NC, POTA K-0683

Sand and Radio

What could be more fun than dancing the biting fly dance to set up antennas for playing radio in the sand and sun?  Hmmmmm.

The weather on the south core banks(‘Great’ Island) gave glimpses of gloom but mostly cooperated very well for a change.  Arriving at the cabin about 1pm local(1700Z) allowed us to unload gear and set up masts and antennas in the normal sunny sandy heat.

Antennas and Station

The main antenna was a 40m/20m trap dipole, with a 15m/10m dipole as a second.  We also set up a 40m EFHW that allowed use of its radiator as an 80m inv L vertical.  We also set up a BOG as an rx antenna using about 200 feet of wire and a transformer.  The BOG made use of the generator hut’s ground wire.  The EFHW was fed on 80m against an 80m folded counterpoise.

The generator ground was free because power was supplied via LifePo4 batteries.  These were supplemented by 200 watts of solar cells once they got plugged in again after being knocked loose.  The main radio used is an Elecraft K3.


The operating was at times interesting and at time tedious.  Pretty much normal for IOTA from NC.  N4YDU started off on 20, but quickly moved to 15m upon finding it more productive.  That was one of the more interesting things, as 15m has been a dry hole for the past few years.  We swapped off every couple of hours or so after that.

The normal mid day doldrums were supplemented by calling both CQ IOTA and CQ POTA and giving out the park K-0683 along with the IOTA exchange.  20m SSB started to pick up during my 2000Z shift.  After that I was happy enough to turn the keys over to N4YDU for some of that world class operator stuff on 40m CW.  One of my highlights is listening to N4YDU pull callsigns out of 40m bedlam at 30wpm.  One of N4YDU’s highlights was moving W1BBB across 9 band/modes for his unique mult.  Thanks to W1BBB for having game! 

Early night 

The evening was capped off by the unexpected termination of the logging computer around 0330Z.  The battery supplying voltage had reached its limit and cut off power to the hub.  Both of us were ready for some sleep, so we pulled plug and prepped for incoming weather.  The weather arrived about 0600z, lighting up the sky and rumbling half of the team to gloomy awareness.  😮

N4YDU capped off the morning chasing mults and possible 15 pointers  around.  W4KAZ snoozed.

It ain’t Over….

After the 1200z end breaking down gear goes much faster than set up.  Plans for possible extra POTA operating were ditched in favor of relaxation.  Everything was down and ready for packing before the obligatory IOTA afternoon storm rolled in.    YDU caught the  storm boat out, and KAZ chilled out and napped on the veranda in the cool breeze blowing in off the Atlantic after the storm.  The early morning boat brought another nice trip to its conclusion.

Crazy Weather

The days leading up to field day 2023 were filled with rain and prognostications of more to come.  While having doubts there would be any chances at having a good chance of operating with the expected lightning, the reservations for the great location had been laid in and paid for.  Tropical conditions could have made the trip dicey, but that junk kept on its westerly track to western Carrib.   All of the NC wx junk was spawned by a low pressure system sitting in TN and throwing moisture at us from FL and the gulf coast.   The “bands” of storms flowing through NC peaked midweek, right through travel to the Island.    bleh.  Arriving Thursday the wx relented long enough to move vehicle contents indoors.  Bands of rain, batches of sunshine alternated ad. infinitum.  Lots of time for relaxation.  Friday afternoon brought a longer window of almost 3 hours of clear wx for setting up antennas.  Then more lightning and rain.

Unique Location

Cape Lookout national park provided a great spot for running a field day operation.  The park is a barrier island on the NC coast.  Beautiful in its own deserted island sort of way.  The wx improved constantly during the four day stay….with the exception of a squall line that that moved slowly through Saturday evening.  Operation was shut down for that period, but there was only rain.  Great time to catch up on some sleep though. 

Mediocre Antennas

The antenna plan was hampered a bit by having only four of the five masts intended.  Something always gets forgotten.  Two 40m EFHW antennas were deployed.  Both were configured as inverted L’s.  The “main” antenna deployed with the horizontal tip pointed North, the second deployed with its tip facing west.  The “main” antenna was also manually switchable to being used as an 80m vertical with a K2AV style counterpoise.   The only band that felt loud was 80m.  These efhw’s mounted as inv-l’s are a bit compromised on 40m & 20m, both by the configuration and being relatively close to the ground.

W4KAZ 1B NC, Cape Lookout qth for the FD weekend, All set for FD. The antennas: Left most and center mast hold “main” 40m EFHW/80m base on left and end at center mast. The rightmost mast holds west facing 40m EFHW which slopes toward ground, and is tied off behind cabin.

No 10m

10m was yet again a disappointment.  The recent rise in sunspots must be less effective in light of the pole shift and weakening magnetic fields.  Radio propagation is probably just a symptom of what might be a much bigger issue.  Keeping the band map loaded with packet spots from VA and NC skimmers showed very few spots on 10m at any time I was on the air.  15m was only very slightly better.  Perhaps Saturday evening was better.   20m and 40m were the places to be for the most part.  20m was more interesting, and accounted for the bulk of the Qsos logged.  The early morning Sunday accounted for the only qsos there, all logged around 0900-1000z.

FD as IOTA Prep

FD antenna choices were made as a test for the upcoming IOTA.  The alternate choice was to mount the “main” N/S efhw as described before, but to use a 50m/20m trap dipole as the secondary antenna.  This second pair will probably be better for an IOTA situation, with the dipole being a better choice for DX.  Alternates/backup antennas are a linked dipole that could be used on any of the individual bands and a set of wire verticals.  Also a 15m/10m trap dipole…..just in case.

The Good, the Bad and the Ugly

Start with the ugly…..a slow band of squall lines moved in Saturday evening.  Fearing more lightning I dropped all the antennas.  Being exhausted, I hit the sack to the pitter-patter of another batch of rain, which turned out to be the last of the trip.   The bad…..missed out on the evening which probably cost a lot of qsos.  But without the much needed sleep, Sunday would have been a tough slog.  10m and 15m were disappointing. Missed packing one of the bags with some of the kitchen odds-n-ends, so had to improvise.  The good…..Morning coffee….two magnificent sunsets on Friday and Sunday.  Cigars and whiskey.  Moderate temperatures and a nice breeze.  Moderate bug levels.

Saturday afternoon was S&P combined with wishful thinking about 10m and 15m.  Didn’t feel loud enough to run on SSB.  Then clouds stacking to the west and a check on the wx radar convinced me to lower antennas prematurely.  The squall line was slow, and arrived with more rain.  Was exhausted anyway so ditched for the evening.  Up at 0800Z and started on 80m to try to capture the available qsos.  Took a breakfast break at the not so spectacular sunrise, then alternated between 20m/40m/15m for the rest of the morning.  Finished up on 20m with the best single hour.  Then a couple of hours of breakdown and packing.  Bada bing bada boom.  Another FD bites the dust.  320-ish qsos, about

W4KAZ IOTA 2022 from NA-067, Cape Lookout NC, POTA K-0683

Schedule is set for another adventure to Cape Lookout, NC over the IOTA weekend.  The plan for operation is going to be a very relaxed approach, depending on the WX and radio conditions.  Activity will be condensed to mostly Saturday, but maybe some POTA calls Friday night or Sunday morning.  Probably will have only 40/20/15/10, and forego 80m.  Probably not worth the effort to add 80m if 20m stays open into the evening as it did for FD.

UPDATE, 2022/08/29.
End of July WX made the event mostly a bust.  Decent WX on Friday afternoon on arrival, so antenna set-up went swiftly.  The weather deteriorated as evening came on, so the Antenna supports were lowered.  Saturday morning brought clouds and lightning.  The weather attempted to clear of for a couple of short windows.  The final window was in the mid afternoon, just as radio conditions began to show promise.  Lightning soon returned along with a couple of driving rainstorms early Saturday evening.

The QSO total never grew to useful levels, and the na-067 mult was scarce from the w4kaz op. 37 QSOs total, all on SSB.

Field Day 2022 – W4KAZ 1B NC

Passed up a chance to operate at the Korn Krib Kontest Klub of N4GU for a pre-planned solo camp out.  Hit my favorite campsite again at Carolina Beach State Park.  I allowed for an optional POTA run at Fort Fischer, but lazy won out over ambition on that one.  Also used the chance to try out a new camping scheme with mixed success.

I landed on the campsite Thursday afternoon, but made a side trip to Kure Beach, then settled in for the evening.  Friday morning was used up sleeping late, making gas run, ice run, and brunch run.

The Antenna Adventure

Setting up the station, a K2, went quick enough.  The two antennas went up easily using the same masts I had used to test them with at home.  An EFHW for 40m/20m and a 10m/15m trap dipole.  FAST……as in too fast.   For some strange reason the EFHW is not tuning………hmmmmmmm.  MAYBE omitting the chokes at the feedpoint are the problem. duh-OH!

The antenna still required a bit of tweaking.   “Strange…it worked just fine at home…?”  I did waste about 75 minutes screwing around before figuring out the chokes were not installed.  After that mistake was resolved I tested out the 80m “variation” that uses the EFHW vertical as a qtr wave on 80m.  That is set up as a separate feed point that attaches to the EFHW via a jumper and a swap of coax.  With the EFHW working, the 80m variation was actually as trivial as it should have been.

Since band switching 80/40/20 required several manual adjustments, I made a cheat sheet/check list for the tired-and-groggy hours.

Field Day Summary

The weather overnight had been cool(for late June at NC coast), and I woke up feeling hopeful.  Never caught any decent propagation on either 10m or 15m, having ZERO qsos on 10m and only 26 on 15m.  80m was so slow I chose going to bed rather than stick it out.  With 20m staying open, the stronger stations stayed there longer.  Getting viable runs was difficult, outside of a good stretch on 40m abt 6pm, and a decent run Sunday late in the event.

The Dirty Truth

The Setup and Station

I ran the Elecraft K2 this year at 75 watts, expecting to put in more operating time overnight than during daylight and wanting to stretch the battery.  At some point I decided to power the radio from the main battery, and use a smaller backup battery for computer peripherals.  This seemed to cause no problems, and helped keep the voltage up on the radio.  In direct sun the solar panels provided about 9-10 amps continuous to an MPPT charger.  The panels only got direct sun for about 3 hours though and were only providing 4 amps or less for most of the daytime.  The battery finished up at about 75%, so the solar assist helped.

WX Saturday was fabulous for late June at Kure Beach, NC.  Cool breeze picked up right about 1800Z. Conditions seemed mixed, and activity seemed down.  Not enough persistence in getting a run going despite seeing decent spot numbers on RBN.  Operating was a lot of S&P and band hopping.  20m was open late and 80m action never seemed to pick up in the early evening.  Eventually pulled plug for the evening before midnight.

I decided to operate mostly CW to keep the noise down in the campground.  Not needed during daylight, but decided to respect quiet hours in park.  That plan was almost blown up by forgetting headphones.  So I used a pair of earbuds that usually ride shotgun with the computer.  I had a second set of buds, but audio was too low a level in those.  Could have made an emergency run to a local wally-mart, but decided to make do.


Got on the air again at 1000Z, and had one of my more consistent runs on 40m as the daytime crowd got back on the air.  Took a break after a couple of hours to scarf a hasty breakfast, then some more butt-on-bench.  The shack was a screen tent that was in full sun for the hours of 1530 to about 1700, so the battery fan helped a lot then.  Sunday WX was also good, but slightly warmer than Saturday.  The only decent 20m run spanned about 50 minutes during the last hours of the event.

The shack was back into full shade by the end of the event.  After a short break for a late lunch, the station was torn down and packed into a single tote, with some notes taken on items missing/needed.  Everything to be re-used for IOTA again at end of July.  Copies of log files made.  Then a leisurely dis-assembly of antennas and parts of camp.  I kept the screen tent up for packing on Monday morning.

No major problems, injuries, issues.  Great weather, plenty of sleep, lots of cigar time, and a chance to relax. Always learn something, and this time learned a pack list is never good enough to catch everything.  And even with everything packed, finding it when needed is a problem.  Still hunting a set of earbuds that went MIA.

Trap Dipoles Ageeeeeeen….Part 3

Trap dipoles Part one.  ..  Trap dipoles Part Two

[edited for links and notes, 2023/07/15]  The original trap dipoles were constructed using coils and caps.  Using Rg-58 for the coax style trap dipoles was rejected because of the weight and size of rg-58 coax traps.  Using RG-58 defeated the primary goal of making the antenna as light weight as possible.

Somewhere I picked up the notion of using rg-174 or rg-316 type mini coax to make the traps.  It looks like the voltage ratings on the rg-174 is higher(1100v rms), so that was chosen for the first experiments.  If luck holds out, the tiny coax will be sufficient for use on the dipole traps for a full 100w CW.  Using the smaller lighter mini coax will allow for lightweight construction from easily available materials that can be easily supported using telescoping fiberglass masts like those available from Spiderbeam, MFJ, or Jackite.  i.e., perfect for portable, field day, rover QSO parties, or POTA/SOTA.

The trap calculator program hosted by KC1KCC gave me some starting numbers to work with, and actual trap measurements came out quite close to the calculated values. [alternate calculator at K7MEM]   The traps are built with the coax coils wound reasonably tight to the form, and the coils were taped down with electrical tape prior to taking measurements.  These are all wound on small sections of the same sort of plumbing drain tailpieces that are 1.5″ od (38mm od).  (e.g., in the US available from Lowes or any hardware store selling plumbing supplies.)  The table below are of traps as built and tested with the nanovna.

END 2024-04-04 Update

Test Antennas:

The test antennas were built for the CW segments of each band. With the best SWR centered on the xx.070 area it will probably give enough coverage for both CW and SSB operation without a tuner.  An 80m/40m version will require tails for 80m adjustments.

Testing of two antennas was done before the May 2022 CQ WPX CW contest.  The 20m/15m version tuned easily….after I figured out I was working on that instead of the 10m antenna.  Read those labels, because at least I had them labeled properly when they were built several weeks earlier.  The 10m/15m version also tuned easily.

[aside: the 15m/20m trap is now in service as the skimmer station antenna, after a recent storm broke the 160m inv-l]

Although I missed the WPX contest, I soon got a chance to do antenna testing at 100w levels.   Both antennas handled the power easily with no signs of SWR rise.  Both were tested at 10 seconds, 30 seconds, 60 seconds  and five minutes of CW key-down.

Hoping for good conditions in FD to allow testing of the 10m/15m version.  Sunspots, do your thing!

[2023-07-15 additional notes]  The coax traps began showing swr problems on 10m after a few months in the weather.  Expecting this to be a problem with water intrusion.  testing the use of WeldBond glue as a sealant.  [alternative….Elmers ProBond]  Also testing the adhesive as a sort of q-dope to seal the coils on the form.

2021 FD W4KAZ 1B NC from Cape Lookout, NC

Very part-time and casual Field Day this year, mostly a vacation break at Cape Lookout National Seashore with a couple of tag-along non-ham guests. Set up of the station late Friday afternoon was pretty low key. Not a lot of work involved. Planting two auger bases into the sand and mounting two telescoping masts was very simple. The 40m EFHW went up soon after. A folded counterpoise radial for 80m was laid out along with a separate feed point box for converting the antenna into an 80m quarter wave vertical as needed. The station was fully set up and tested Friday evening.


The FT-891 was used along with an MFJ external tuner, mostly for its ability to double as an antenna switch. Computer logging with N1MM was tested and ready. Very simple. The most complicated part was configuring the sound card settings to use the computer for voice keying. The station was completely battery powered, and the battery was supplemented wit 200w of solar panels. Everything tested and working early Friday evening. Just in time for bacon wrapped shrimp kabobs, supplied by tag-along companions. And the obligatory whiskey and cigar break.

Saturday, time to welcome Murphy to the party

Count on Murphy to make an appearance RIGHT at the start of FD event. Somewhere along the way the logging computer went to sleep causing N1MM to delete the logging files along with all of the settings and drivers for communicating with the radio.[The *.s3db file disappeared, although that was determined a few days later.] The first hour was blown trying to re-connect/configure N1MM with zero success. So it was time to ditch N1MM in favor of using Writelog. The only reason N1MM had been set up was that it could connect to the FT-891, which I cannot get set up in Writelog. Switching out to the Elecraft K2 backup radio was considered, but instead decided to forego computer-to-radio comms and do band changes manually. That was certain to have caused some log errors, but it was simpler than switching radios while angry/disgusted/tired.  My low opinion of N1MM logging program was reinforced.

It turns out there was no burning reason to rush. Saturday conditions were none too interesting, with little activity on 15m and 10m.  The relatively weak antenna for 15/10 did not help that situation. Or maybe everyone has switched to digital modes. It also became apparent from RBN spots that the antenna orientation was heavily favoring Europe instead of the US on 15m and 20m. So a bit of SSB S&P on 20 and 40. Also took the opportunity to fiddle with the antenna by removing the jumper to make it a 20m EFHW. This worked better for 20m in the short time on the air before dinner.

Being mostly casual, the folks that tagged along for vacation time pulled out the night’s meal. That was later accompanied by a bit of whiskey and cigar time. When the tag-alongs decided to turn in for the night it was time to get back to radio for a bit around 0400Z. Being 80m time, a foray out among the bloodthirsty nighttime island fauna was required to make the manual switch from 40m EFHW to 80m vertical.  A nice hour on 80m proved the function on that band.  Pretty good for a last minute kludge idea.  In bed for the night by 0500Z.

Day 2 – Sunday

After a shift on breakfast duty it was back on the air at 1015Z. Worked a few more on 80m before switching the antenna back to 40m EFHW configuration. Then it was a CW run on 20m, to 40m, back to 20m for a good hour. Did a lot of band hopping after the 20m run through 1630Z and called it quits early. As always, tearing down the station and antennas went really quickly. Plenty of time to enjoy the afternoon. The FD log ended with 250 Qso’s – 25 SSB and 200 CW.


The weather over the entire weekend was really nice. Most of the weekend had a cool ocean breeze blowing, instead of the more normal southwest blow. Skies were overcast the first two days, but began clearing Saturday. Sunday evening produced a clear sky and a flowing Milky Way which was followed by a later moonrise just past full moon. It is interesting how brightly lit a desert island becomes under a full moon.
