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.
I built my own 600 w output amplifier in 1977 (2 x 813). I worked 175
countries with that setup.
My first computer was a used C-64 in 1991.
Now I have a FT-757, a Swan 700 and a PRM-4021. Excellent little radio.
Is the workhorse nowadays.
It is a pity I could not get a 4031, the same thing, all band ,with WARC
bands included. I reoaired my own 4021
and made a 100 w solid state amplifier with two 2SC2290. I have had the
PTC-II since 1998 too, and P III license
since 2004.
Have been teaching in Africa for more than a year. Brought a PC with a
P4 and good soundcard.
Here, it is a bit more difficult to get radios and parts, requieres
quite a bit more per$everance.

PS: There are at least two ways to do the same thing: The american way
and the european way.
ex: Cadillac-Citroen
PK232 - Hamcom + Baycom
etc, etc, etc.
