Steve, I understood Carl to mean that the d-c input power is not directly reduced, but that the r-f drive is reduced such that the final current remains under 20 amps. That being the case, both the a

Thanks very much, Carl, for clearing tht up for me. 73/72/oo, George W5YR - the Yellow Rose of Texas Fairview, TX 30 mi NE of Dallas in Collin county EM13qe Amateur Radio W5YR, in the 56th year and i
It is a tossup, Jeff. The meter on the Jupiter is really showing an indication of how close to a 50 ohm resistor the transmitter load is. The AR meter is actually measuring the impedance of the line
Well, let's look at the other side of the story: If a system can be updated or re-defined by a single ROM flashing, then this suggests strongly that the system is fairly unsophisticated in that it ca
Reality check, folks. While I do not doubt what TenTec has told us so far, it is a little overboard to make such statements as "The software to implement the features and functions in the Orion is mo
But didn't the infamous Collins digital computer project that nearly wrecked the company use serial communication throughout instead of the more common parallel bus approach? 73/72/oo, George W5YR -
Carl, just one question: Does the 340 have a DSP dynamic range of only 40 db? Or is that a typo? The PRO uses 24-bit AD/DA data which yields a theoretical 6*24 = 144 db overall range. Toss out the LS
Steve, you should see the remarks I get when I tell them I am using a 50-Hz filter with the AGC action confined to that passband! I go from 3600 Hz bandwidth for signal searching to 50-Hz centered ov
Think back to the waterfall on Peter's first program . . . 73/72/oo, George W5YR - the Yellow Rose of Texas Fairview, TX 30 mi NE of Dallas in Collin county EM13qe Amateur Radio W5YR, in the 56th yea
Don't have one, Brian, but seems like you could put the rig in AM or RTTY mode and do a manual PTT to output a carrier for the tuner. That way you would not hear the CW sidetone which I presume is wh
Sorry, Larson, but you are bootlegging someone else's call. Why not use your own: WIOU <:} 73/72/oo, George W5YR - the Yellow Rose of Texas Fairview, TX 30 mi NE of Dallas in Collin county EM13qe Ama
I found a picture of the front panel of my main rig on the Net at the manufacturer's website and saved it and then made it my wallpaper. I think that I also ran it through a photo editing program to
Bob, I notice in every case that you used the internal analog audio circuitry in those receivers. If you ran an amplitude and phase frequency response on those radios you might find considerable diff
Steve, I suspect that lack of an external speaker jack comes with the type of audio output circuitry used in the Pegasus: balanced output to ground and no ground. A two-circuit connector would have t
Hi, Lee Interesting post - thanks for the info. I mount the little Radio Shack isolation transformers in old 35 mm plastic film cannisters. I put a mini-jack in each end and wire the transformer to t
Roy, I don't know what you are looking at, but when I look on a scope at the output r-f envelope of my PRO sending continuous dots, I see textbook perfect dots and spaces of equal lengths. Not saying
Paul, I use MixW for most digital modes and SpectroGram for general spectral estimation. I have found that I can readily see a 10 Hz change in frequency on the waterfall under steady state conditions
