I am not a Pegasus owner, so my horse is not in this race, but from what I have read on the reflector, TT has a history of designing amp stages that *must* be loaded rather correctly or they draw too

How would the group feel about an almost fully digital radio built around a DSP "core" operating at 30 to 50 KHz, with up and down converters and amplifiers, etc. before (for receiving) and after (fo
Sounds like there may be some ambiguity in terminology here with 3rd and 5th harmonics being mentioned one place and 3rd and 5th scale tones or intervals another. They are, of course, not the same .

My Icom PRO with its 36 KHz IF and my Kachina with it 40 KHz IF certainly do not have any flies on them compared to my conventional quadruple conversion Icom 765. In fact, in most instances, they bot
Mark, that is precisely the way my Icom IC-756PRO operates. After locating the DX station on one VFO, I lock it on that frequency. Then by merely pressing and holding down a button I listen on the ot
Bill, I think that you have point up very well that the misnomer "software-defined" is really not the same as "software-controlled." Too many manufacturers and a lot of innocent hams are confusing th
Lee, I don't use a PEgasus or Jupiter, but I do use the Entrega 2U4S port expander device. It plugs into the computer USB port and expands to two more USB ports plus 4 sserial ports. Powered by a wal

Jim, Dick Flanagan's Icom list has since Day One always replied to the list by default. One must do a little extra in order to send a private response. This has been argued repeatedly over the years
Excellent summary, Tom, but I do have to take exception to one statement: "Only Kachina, Actually, the Kachina 505DSP was on the market quite some time before the Pegasus, etc. If you are referring t
Steve, Thanks for the reminder about the 870 - I had forgotten about it. I think that the real achievement with the Pegasus was boiling down a DSP transceiver into a package at a competitive price po
No problem here, Tom, and thank you for reminding me that Ten Tec used DSP as long ago as 1990. My first experience came a little after that when I bought a JPS NIR-12 audio DSP unit to use with my I
Duane, I still owe you a private response to your last email, but I just couldn't resist jumping in here to refute the quoted statement below. Actually, some of us *have* figured it out! <:} I would
The Icom IC-756PRO has rise and fall times on the keying waveform selectable from 2 ms to 8 ms. I have verified by scope examination of the r-f output waveform that these numbers apply to the actual
I recently posted in response to some of Ken's comments denying that I had tinny or poor audio on receive from my PRO. That is a true statement, but I failed to point out that I take the receive audi
Paul and all, Back in the dark ages of the mid-40's I built the famous old "electronic keyer" that had been in the Handbook for several years (page 141 of the 1946 edition). You know, the one with fo

Good account, Bob. Been there and done that to a large extent . . . didn't get the t-shirt, though! <:} The most compelling evidence of your presentation is a comparison between the Pegasus and the K
