How about a ham who invested $3500 in Orion, and is unable to invest a similar amount in a "compatible" amplifier? On the other hand, the real cost (if any) of providing (ore rathet preserving) PTT f

Sure it would. On the other hand, a manufacturer that forces you to buy a new amplifer so that he can save 5 cents on PTT is probably missing something. 73, Sinisa YT1NT, VA3TTN _____________________

Or eat cakes :-) Jack, we are talking about 5-cent effort on part of TenTec, vs. $multiK-effort on part of many customers. If RX/TX control is done by CPU, even those 5 cents can be saved, unless the

Looks like it is. The waveform is typical of the breed. No, it cannot be so, because it would require Orion to cease transmitting before the key is released. 73, Sinisa YT1NT, VA3TTN ________________

If there has to be vertical wire, it would be much wiser NOT to ground it. RF power forced into soil produces no signal. So called "half-slopper" antenna is a dipole (as most antennas are) deformed s

Hi Rick, OK, let's see if you would agree with physics :-) It is a simple fact that pushing RF power into soil does not produce useful radiation, although some other goals may be achieved, like "perf

You can run one dipole leg vertical, and other horizontal, or zig-zag, or in any other fashion. Resonant frequency will change slightly, but that's easy to correct. Look at "Low-Band DXing from a Sma

Nice example of what I did recommend to Ken. Call it any name you like, I just see a good old trapped dipile, distorted to fit the space. Adding the second "radial" is also a good idea. Nice to see

Well, I find "energy" and "intelligibility" quite interrelated, i.e. one cannot have the later without the former. True :-) Should be so, although I wouldn't advance lower cutoff any further, unless

It gets worse with 3 signals. If the first filter is 15 kHz wide, then almost half of the 7 MHz CW band passes through, gets amplified by ~17 dB and reaches the second, mixer which is much weaker tha

It depends on the transmitted signal. If nothing is transmitted below 500 Hz, then there is no point in receving below 500 Hz :-) Let's forget QRM, because it may come from all "directions". Let's al
