K2 Impressions – Part 6 – K2 vs K3

After spending some time operating the K3, I’ve been trying to decide how I liked it. Truthfully, I liked it a lot.

But I must also admit that I still feel like the K2 is a better fit for my own purposes.

Unfortunately, I haven’t done a side by side comparison, and all of my judgements are subjective and anecdotal rather than measured scientifically. But one does not operate a rig scientifically, one hunkers down and spins the dial, looking for the pearls amidst the flotsam and jetsam.

The K3 variable bandwidth and bandwidth shift features are outstanding. I really enjoyed operating the NAQP with the K3. Its receiver is every bit as good as anything else I’ve heard. But I think the K2 holds its own against big brother. Without a side by side A/B test, it seems the receive quality was very similar.

The K3 has many features the K2 lacks. It will have a true second receiver. There are also the RTTY and CW features. Etc., etc. Some of the ergonomics are better on the K3. But for my own uses I won’t normally need most of the additional features. The K2 receiver, with the DSP filters, is very close to the level of the K3. So, for my own part, an upgrade would not pay for itself.

None of that is really a knock on the K3. It is more an indication of how much I’m enjoying the K2. I just prefer the simplicity of the K2, and its performance on the bands is very close to top notch. I would probably buy a second K2 if it came down to brass tacks.

If money were no object, the stack in the shack would be K3, Orion, Omni-VII, K2, Omni-VI+,Omni-V, sorted by how well I like their receivers, not by the most loaded. But to contest on a budget, the list re-sorts as K2, Omni-VI+,Omni-V,Omni-VII,K3,Orion. Maybe wedge the FT-1000mp in between the Omni VI+ and the Omni V. Maybe.

K2 and K3 don’t need much desk space either. Omni-VII comes close to their size, but is not quite that compact.

So, K2 is going to be a long term keeper, no matter what else might eventually move into the KazShack down the log.

Zero, With a Mean of….

From todays K7RA propagation forecast:

“”Sunspot numbers for August 7 through 13 were 0, 0, 0, 0, 0, 0, and0 with a mean of 0.””

Well.

Whoop- tee -doo….

And odds are several months more of that excitement is sure to follow. Ick.

WKAZ, W4KAZ – Not Quite The Same.

During IARU a QSO with a WV ham apprised me of the fact that “my callsign” was already being used by a broadcaster in the Charleston area. So, curiosity led me to find 107 KAZ. As luck would have it, you can also listen to their stream via the web. The link is a javascript so I can’t link to it from the blog, look for “Listen Live” at the top of the right sidebar.

They also have an AM affiliate, but the AM side doesn’t have a stream that I can find. Its unlikely I’ll be able to DX them with my radio either, as they occupy 680, the same frequency as 50kw WPTF. I’m only about a mile away from WPTF’s antenna site, so once again poor KAZ is overwhelmed by the high power Big Dawgs. WKAZ is only allowed 244 watts at night – WPTF’s HARMONICS are louder than that!

Cool. If I ask, I wonder if they will send me some promo material? I guess not, because W1KAZ, W2KAZ,….W0KAZ might all ask for freebies too.

K2 Impressions – Part 5 – Post IARU

I am more pleased with this radio every time I use it. The K2 was really a joy to put on the air during IARU. The CW copy is good. The narrow filters are remarkable, relative to most other radios that I have tried. Good CW audio in a very narrow passband with no ringing detectable. I found myself wanting to break away from my “run, run, run” operating game plan. My original intent was to practice my run skills, but I found the K2 to be so good at S&P mode that I wound up doing a bit more S&P than I originally intended.

With the K2 filter set to 200 hz, S&P turned up workable stations every 200 hz. I was able to hear the weak stations down in the QRN that I probably have never known were there before. I was able to work many of them. It was a genuine “Wow!” experience.

I have yet to master many of the nuances of the K2’s operation, so I did run into a couple of “moments”. I acquired a KAT100 only a couple of days before FD, so I’m not completely up to date on its operation. I found this to be a problem when switching between antennas. That’s a problem, because I like to flip back and forth between alternative antennas. I need to dig into the manual and deepen my understanding of the tuner.

The KAT100 is pretty slick though. It tunes with low power, and it is very fast relative to my other rig.

My only other real issue is with the rx audio levels. I have several sets of headphones to choose from, and all are different on the K2, much more so than the other radio. I found myself juggling through several pair during the ‘test. The differences range from extraordinarily bad to passable. None of the current crop of headsets rise to the level of good. This is something I will need to resolve, because the headsets are a “must have” preference.

I’m now looking forward to getting the 160m option built and added on to my K2. S&P in the 160m contest is sure to be a lot of fun with this radio. Also, it will be nice to have the rx antenna input again. That is a feature of the 160m option. It is a feature I really like for 80m and 160m – I’ve become a real fan of using an rx antenna on 80m and 160m. I’ll begin on that mod after the IOTA weekend.

The issues I have with the rig are minor compared to how much it has added to the joy of operating.

Sunspots – Poised On The Cusp III

A re-iteration of the “that’s our story” comments from a couple of weeks back.

I’d rather not contemplate a FIVE or SIX year minimum…!! But as Hathaway notes, the records show it has happened before, so it is well within the realm of ‘normal’. O’ course, the records also show the Maunder Minimum. It makes a reasonable person wonder just what ‘normal’ really is, given we have a pitiful few observations for only the most recent tiny fraction of the nearest star’s lifetime.

Just imagine for a moment how different radio would be if it had been invented at the beginning of an extended solar minimum.

What a surprise it would be when the spots picked back up. (“wow This is GREAT!!!”) Everything is relative to one’s expectations, aina?

CW Skimmer – Top Ten Reasons Skimmer is the Same As Packet

The proof is in the pudding.

In the grand scheme of contesting, I’m just an ankle biter, but when one of the Big Dawgs barks, it’s worth noting. W4PA posted some notes in his journal, dated 7/14/2008, that confirm every speculation made by folks who argue for making CW Skimmer fall into the “Assisted” category. Scott operated the IARU contest with CW Skimmer up and running(actually he used six).

Quoting W4PA, (emphasis added is mine):

  1. “”Does it work? Absolutely.”
  2. “”It looks just like packet spotting””
  3. “”The callsign quality was good, I’d say 90% of the calls spotted were correct“”
  4. “”The Skimmers also alerted me to the 10 meter opening in progress””
  5. “”On 20 meters early on I had 600 available calls to be worked at one point spotted by the Skimmer””
  6. “”Does it look and feel like packet? Definitely“”
  7. “”If I didn’t know what it was, I would have assumed I was looking at packet spots“”
  8. “”Is it different than unassisted traditional single op? Sure.””
  9. “”Is it an advantage over unassisted single op? No question.””
  10. “”It may even be better than packet, because it gives you ALL the callsigns for the whole band. “”

Reading what I’ve written previously, you might come to the erroneous conclusion that I think skimmer is bad. I don’t. I just think the rush to allow it in the ‘unassisted’ category is bad. The tool itself is inanimate. It is the ethics of thecategorizationof its use that I question. Read W4PA’s whole post.

It walks like a duck, quacks like a duck, makes messes in the grass like a duck….it’s a duck.

Et tu, Charlotte?

Scott, W4PA, has posted a couple of hints that the Charlotte hamfest will also be relocating to new digs for their next show in 2009. Scott indicates the Carrabus Arena will be their new home. First Shelby, now Charlotte.

This will be good news for those of us driving in to their ‘fest from the RTP/Raleigh/Durham area, and maybe for the Triad folks too. A Carrabus arena location will cut almost an hour off the drive from this area. The Carabus facility is almost brand new – another small bonus.

The Charlotte move is being caused by the sale of the Charlotte Merchandise Mart to a church. The club has little recourse. I hope they are able to make the shift to the new location smoothly. I’d recommend that they update their website to get the word out ASAP. It still has 2008 info with the old location. Perhaps its all still being finalized, and I’m jumping the gun.

I’d bet that W4PA has the straight word, since he’s a rep for one of their better customers, TenTec.

More Shack Layouts – Photos For Ideas

K8ND has acollection of SO2R shack photosthat should help with getting layout ideas. Some are simple and some are elaborate. Some layouts appeal to me for different reasons.

I like N4TZ’s layout because the Vee shape allows some access to the rear of the gear. My shack space was too limited for this, so my own design is on wheels – I can pull the whole kit away from the wall for snaking wires.

I also like the K3PP shackbecause I like the simplicity and versatility of the small shelves for vertical gear stacking. My own cabinet is somewhat less versatile, but good enough for now.

The KazShack – Homebrew Station Cabinet/Desk

I spent some time re-arranging the station area in the basement cubby-hole after unloading the jed-clampett-mobile(my stuffed to the gills truck) in the days following Field Day. Here’s a picture to remember it by, because I’m sure it will soon again be covered by several years of miscellaneous unrelated items. Things seem to find their way their over time.

Photo of the re-arranged KazShack, post 2008 Field Day Here’s what the operating position is looking like after I re-sorted everything out after field day of 2008. On the bottom row, the FT-920, Diawa wattmeter, and Elecraft k2/100 w/KAT100. On the next level up, an MFJ tuner on top of MOAT, the “Mother of all Tuners”. centered is the junker laptop and K9AY switch, then the Yaesu SP-8 speaker with another MFJ tuner on top. On the top of the cabinet is the “wishful thinking”, a Ham-II control box(attached to nothing) and the switch box for an incomplete home brew remote switch project.

The desk itself is something I designed and built five years ago. Its major shortcoming is the lack of space for a monitor. I was previously using a side cart for the computer and monitor. Since I now have an old laptop for my logging, I have it included in the desk set up. The side cart is now gone, but I will build one to match the desk at some point. The Ham-II controller is a place saver, since I don’t have any tower or rotatable antennas up….yet.

The KazShack operating desk The KazShack desk, front view The KazShack desk, side view

The desk itself worked out very well otherwise, since my operating area is so physically limited. It’s nice to be able to fold up the desktop. Since the desktop also acts as a fold-up door, I can close and lock it up if bneeded. The whole kit is on heavy duty casters, so I can roll the entire station around fairly without needing to be too careful. It DOES help to unplug everything before trying to roll off with it. 😉

In use, the desk level shelf and the shelf above are in easy arm’s reach. Anything on the top of the box is a stretch, so its somewhat inconvenient to put tuners and antenna switches up there. The very topmost shelf is mostly out of reach for me, so use it for storage. The area below desk level is perfect for the APC line conditioner, power supplies, and the fire extinguisher. The desk top is itself held by permanently attached steel cables, and two fold out brackets below the desktop. I wasn’t up to the challenge of pocketed brackets, so they are hinged to the front of the frame. The desktop is at 27 inches, which I find the best height for me, and it has a slight slope downward when open. Just enough slope that pencils will roll off. Grrrr. I did that on purpose. Sometimes I think it was a mistake, but it makes long periods of operating and logging comfortable.

The photos don’t show it very well, but the desk is stained in two different tones. It was a carpentry experiment that worked. If I can find the plans I drew up for it, I’ll post them. The construction is simple, using common dimensions of lumber available from any big box here in the US. The frame is constructed of 2×4 and 1×4 material.

The case is actually aseparatepiece, just sitting in the frame. It’s weight is enough to hold it in, as long as no one is goofy enough to try and sit on the desktop when its open. It is constructed of 1×6 and 1×4 lumber, some of which is edge joined to make wider pieces. All of the lumber is pine, so it tends to scar easily. I’ve been touching up the dents and dings with matching stain, and I like the lived in look the markings add to the piece.

With the desktop closed the whole thing is just over two feet deep, so it occupies a relatively small footprint. It is a bit less versatile than a larger flat desktop, but I needed a space saving solution. If I ever get the chance to move to a larger area, I’ll have a new project – matching extension pieces.

TR for Windows

I picked up this link up from Scot, KA3DRR and RadioDawg over at the shackadelic. There’s a project going on to port TR over to Windows. The product appears to still be in beta testing, and I understand there are still some outstanding issues with CAT control for certain radios.

The hardware requirements appear to be relatively modest. Leisure funding isdisappearingas college tuition for the eldest son kicks in for the fall of 2009. If I can run it on my old clunker CPUs, it will be worth playing with.

I have been using Writelog since returning to radio, and I am happy with it. It is a good program, and written efficiently enough to run on my junker PC’s. I will continue to buy support for it, as most of the open source software I have used is bloatware, requiring far more CPU and memory resources than the modest tasks of logging actually require. It just rubs my professional feathers the wrong way.

But the major reason I’ll keep supporting Writelog is that I don’t want to see the logging software market dominated by any one vendor. I’m willing to put my money where my mouth is on that issue. It’s a small price to pay for a job so well done.

That’s all irrelevant to the TR4W project. I’m glad to see this being ported to a windows platform. I’ve never really tried it out, but TR certainly has a core group of True Believers.
