Hi Jim, LF,
Things were going well, some slow QSB took you from initial -12dB down
to -20dB. Just as you started to climb back up I'm engulfed in a
statically charged snowstorm!
I'm using my short capacity loaded vertical (as used on 500) with the
MF ATU replaced by a ferrite transformer at the feedpoint. I'm trying
to ascertain if it's necessary to use a tuned pre-amp in the shack or
not. After several decodes between -20dB and -17dB (with the pre-amp IN)
I started a sequence of IN, OUT tests, but that's when the charged snow
started to fall and obliterate everything... so no further data
collected.
I'll leave the RX running, pre-amp out, overnight. I guess you'll QRT
soon. Thanks for the tests, my first ever amateur signals on 136kHz.
Cheers,
John
