Most of the radio equipment that hams use today are commercial products.
Of course some do home brew them as well, and some, such as myself make
many other devices (active antennas, meters, QRP rigs, interfaces,

I used TERMAN93 with a homebrew FSK modem and my PC in 1997 was a 386 at

oscillator to shift it from 14.312 MHz to the correct frequency of

I never knew about G4BMK Multi. But My PTC-II does that and more, too.

Hello Demetre,
Please let me know, the frequency you mentioned is it display frequency and
are you going to
use LSB or USB?
It is the display frequency (3617 KHz) on your XCVR and in USB.
Note: you can also send files without errors (but small files except if you are
very patient).

Off list, to avoid clutter.
Well, my first setup was a Johnson Ranger and a HRO-60, heavily modified
(1972).
I built a multiband (80-40-20-15-10 m) phasing transmitter with a fixed
9 MHz IF.
Quite similar to a Hallicrafters HT-37. (1973)
I have used dipoles or verticals always, no beams.

Perhaps we should try 40 meters next time. My aerial is not very
