[Lowfer] Lowfer JH

[John Hamer]

I have lowfer JH running at a full watt again. Still the same mode.  Qrss60
with a JH graphic. I may power it off and on a few times through the next
few days. But it will never be off more than a minute.

I thought my transmitter or antenna had an issue because I could no longer
get a full watt with my 24v, but I think it's just something to do with the
weather? Like humidity with cooler weather maybe? I'm not really sure,  but
I bumped my power supply to 27v and it seems to be doing well.  I think I
remember running a higher voltage last winter. I connected the transmitter
to a dummy load and the waveform and voltages are exactly what I would
expect.  The capacitance of the antenna measures the same.  I checked and
cleaned all ground connections. I suppose there could be a bad connection
from the antenna to the top hat, but they are soldered connections with
epoxy over them.

Last winter I was powering the transmitter from 2 12v lead acid batteries
in series.  I built a voltage booster that brought the voltage up to a
stable 28v. That fed into an lm317 voltage regulator that controlled the
final voltage.  I removed the booster when I moved away from batteries.
