Chasing down the RFI caused by inserting all of the home-brewed SO2R components into the station set up was a useful hands-on experiment. Annoying, but certainly educational. I verged on ordering the ARRL RFI tome, but now the thing is fixed, owning the reference seems less urgent. Might be worth reading though…..probably quicker than re-inventing [...] Leave it to the RedmondGeeks to create a useful tool but leave it undocumented rather than make it easily available. And a big thanks to NumberOneSon for showing me the trick. There’s a feature for Windows 7 users called GodMode, which is simply a tool/folder that has a lot of the more useful system administration tasks [...] ENVIRONMENT: The following applies to an install of Writelog on a Windows 7 64 bit platform with User Account Control enabled. Probably works for any Windows 7 version. It may also apply to Vista, but that version of Windows has not found its way into my hands, so experiment at your own speed. All installs [...] After building the 80m/160m splitter, it seemed like the signal levels from the K9AY were down a bit, probably from losses in the filters. So after looking around at pre-amps, and procrastinating on buying the Ar2 preamp, I again landed on the W7IUV site. W7IUV has updated his preamp schematic, and it looked easy enough. Building [...] Finally figured out what to do with burnt out strands of Christmas lights. Scavenged about 100 ft of wire in 20-25 foot long hunks and used it to augment the radial system on the K9AY. The K9AY RX antenna itself is in need of replacement. It is constructed of 18ga wire, and has had several [...] At this time I would like to make a public statement acknowledging the fact that I am in no way connected to the publication of the Lost Island DX Society, the “Fi-Ni Report”, nor any of its paraphernalia dispensing outlets. I reap no monetary benefits from the sale, promotion, nor dispensing of any of the [...] At the bottom of this page is an accumulation of some of the SO2R resource materials I used in developing my own custom SO2R solution. My first SO2R post hashes out the thought process involved in choosing the homebrew methodology for hacking together a workable SO2R set up via home brew components. The big issues for [...] Part 6 of the W4KAZ filter project series discusses the actual measured S-meter calibration, and the filter attenuation estimated based on S-meter measurements. As I meandered through Part 5 of this group of posts, I needed to find a way to calibrate the S-meter scale on the FT-920 to a 6DB reference. Lacking any real test [...] With Field Day right around the corner the K3NG Home Brew Field Day Tarp Canopy seemed timely. I don’t have(i.e. “will not have”) a google account, so I couldn’t post comments to K3NG’s post. But it’s cool enough to bookmark permanently. Literally. Putting shade on the tent keeps the operating position much cooler. My initial reaction [...] Part 5 of the W4KAZ filter project series discusses filter losses, an idea for getting a very rough S-meter calibration, and trying to estimate the out of pass band attenuation provided by the filters. The Losses: The filters do have losses in the pass band. This is known as the insertion loss, and is reported in db. [...] |
