Kevin asks about (older) Ten Tec PowerMites.
I have experience with the PM3A, the 40 / 20 meter 5 watt transceiver.
It had a Direct Conversion receiver, sensitive, but not selective. There
was an optional passive audio filter sold for it, and it did a reasonable
job, but rang pretty badly.
The PM3A ran on 12 volts, of course, and had a meter for tuning up. There
was a tuning procedure - not like most transistorized rigs that are ready
to go when you move frequency. It was no real hassle, though. The
tuning dial was very rough, no calibrator, so you have to watch band
edges. The QSK worked very well, I recall being quite impressed - the
rig I had come from was a Heathkit HW-101 (semi break in keying). I
suspect I did all this back in about 1972 or 73. Got me into QRP ARCI
back then, hence my low number (BUT, QRP ARCI then stood for the principle
that we should all run under 100 watts input power, if I recall
correctly.........! I was QRPp at 5 watts.)
I ended up working a LOT of my time with the PM3A. I really enjoyed it.
If my memory serves me well, it compares with the HW7 and HW8, as I
remember them, however, the PM3A can be had for less money at swap meets.
(It has fewer bands and is older).
