Rod You're most likely getting the 22m SW signal rectified at the product detector. If using a tuner doesn't help, you could try a 1/4 wave stub tuned to the offending frequency; connect it in parall
That extra 3 dB or so at the other end will have negligible impact, unless it's crossing the make/break threshold with regard to the noise floor. It doesn't seem to be worth the smoke. Al, K2ZN
Paul Here's a good starting point to identify what you need: http://www.airpaxppp.com/pppsite/tproduct.html 73 - Al, K2ZN I am in the process of standardizing all of my wiring between the power suppl
Not necessarily on the run, but short on funding. There are plenty of legitimate entities out there that just can't justify buying something like a PRC-150 when they could get 10 commercial rigs for
I built one up years ago, using a shaft encoder gleaned from a junk pile. Not an aesthetic masterpiece, but it certainly works well. Al, K2ZN Isn't this just a standard Omni V/VI optical encoder in a
As I recall, the blanker in the Scout works pretty well. All you need to do is locate a source of impulse noise - lawnmower, snow blower, old car, etc. and switch the blanker on and off. The noise sh
John I have found that the header socket on the display board tends to lose its "spring" over time, resulting in poor or sporadic contact. What I did with mine was to gently push the mating surface b
It's not the digital waveforms that are the problem, it's the implementation thereof. The first one that comes to mind is Pactor III, which has been making a mess of the 14060 kHz region.
It most likely has to do with the trade-off between cost and processor speed, as well as the 24 bit A/D limitation. When these technologies become more affordable to the commercial world, things shou
Listening with an AGC-free direct conversion receiver while throttling the RF gain back would be a good starting point; they tend to add significantly less "color" to received signals than the superh

I've got an 10' run of parallel sections of RG-62 between my (genuinely balanced) tuner and the wall where it meets up with 600 ohm open line. Obviously, it's a compromise, but most of us have to mak
Methinks that the newer generation of radio-esque equipment will replace RF connectors with the ubiquitous RJ-45. Al, K2ZN Haven't we seen enough rigs with coax connectors on the back? Wouldn't the O
Over the weekend, I handed out a few random points for CQWW. Not being much of an SSB op, I found the wall-to-wall cacophony to be difficult to deal with. This prompted me to do some A/B checks to se
A slick thing to try would be to put a really good (e.g. Datong FL3) audio filter in place of the the stock CW filter in a Triton or older Omni. Of course, the line levels and Z would need matching.
Joe I've had very good success with Teflon bicycle bearing grease. I just recently re-lubed a C/21 and Omni A without a hardware rebuild; both are working fine. Al, K2ZN I'm fixing up my Century 21 w
Has anyone seen or picked up any interesting TT goodies at a recent hamfest? Any good CFO squawks on 40m? New DX (using TT gear, of course)? Al, K2ZN <snip> Anyone received the TENTEC Argonaut or Ori
