The math is equivalent and there's no way you can distinguish a CW signal that starts life as a keyed AF tone and gets mixed up to RF and one that starts as; /archives//html/TenTec/2005-04/msg00564.html (9,341 bytes)

The idea of "CW" is that you have a keyed oscillator at some frequency, and that oscillator may get translated (or even multiplied, in the old days) to; /archives//html/TenTec/2005-04/msg00570.html (10,268 bytes)

The relevant sections are 97.3 which refer back to 2.201 and 2.202. Some excerpts are at the e; /archives//html/TenTec/2005-04/msg00642.html (12,525 bytes)

I remember some A2A code practice on 2 meters years ago. I think the reasons for A2A were rigs designed only for voice (no key input on Tx, no BFO on Rx) and rigs that weren't; /archives//html/TenTec/2005-04/msg00646.html (10,937 bytes)

For me, the stock filters have been fine. Better to put the extra cash into aluminum, or possibly Jack Daniels.. hi 73, Martin AA6E; /archives//html/TenTec/2005-04/msg00677.html (7,692 bytes)

It will also blur the image to some extent. You might get more help with eithe; /archives//html/TenTec/2005-05/msg00037.html (10,333 bytes)

The Orion attenuator comes after the diode switching matrix and voltage limiting (+/- 5 V) diodes, some of which are being driven nonlinear IMO.

Of course, if you've got it, it's important to you. What would be very helpful, at this point, are some simple engineering tests; /archives//html/TenTec/2005-05/msg00649.html (8,940 bytes)
