After 8 years without a HF SSB transceiver of my own, I finally got one at Xmas.
A uSDX which covers 3.5 to 30MHz at <5 watts. It draws 900mA max at 13.8v and 80mA on receive.
Set up a dipole in the loft which is resonant at around 7 and 21MHz, not by design, that's just the amount of wire I fitted in there.
Power output from the uSDX on a 13.8v PSU:
1.8MHz = 4.5w 0.74a
3.5MHz = 3.3w 0.51a
5.3MHz = 3.8w 0.65a
7MHz = 3.0w 0.85a
10MHz = 3.1w 0.52a
14MHz = 2.7w 0.53a
18MHz = 2.5w 0.4a
21MHz = 1.7w 0.37a
28MHz = 3.0w 0.66a
