Paul,
sorry.
Even with 240mA the transistors went to hot, about 120°-130°.
I finish. Perhaps you can look for the last 2 0r 3 hours.
A nice evening.

Hi Paul, Stefan
I hope i have solved the problem. The antenna current with 332mA
was to much. The Amplifier switched off. Now I am using 240mA.
and try again. Transmission was running the last 2 hours, almost
all the time which 320mA.

Hallo,in
ich hatte den Artikrl als defekt gemeldet und sie haben das
Geld an PaxPal zurückbezahlt.
Jetzt wird gemeldet, dass ich nicht bezahlt habe.
Wo ist da das Problem? Wollen Sie, dass ich den defekten
Artikel zurücksende? Dann senden Sie mir bitte einen für
mich kostenfreien Zürücksendeschein. Ich bitte, dass das
geklärt wird.

Hi
Paul, VLF,
Wonderful! I like the long messages. The next one will be even
longer.
You may have noticed that there was an 'issue' again with my
system. This time the power supply collapsed :-) But the PA is
my own construction and so i would understand and know how to
repair it!
Will repair the supply now an d then back on air. Message
announcement will follow.
Ah and i ordered 2 feed-through ceramic isolators from ebay lat
night (http://www.ebay.de/itm/14-Euro-fur-1-Paar-d-h-2-Stucke-Antennen-Durchfuhrungsisolator-aus-Keramik-/131791851901?hash=item1eaf68117d:g:4~MAAOSwCypWpURh
).
Hopefully the creepage distance is high enough :-)

Another success.
Copied 'DREAMER' at rank 3, Eb/N0 = +0.8, BER 34.5%,
constant
reference phase. Signal averages 16.04 dB in 54.8 uHz.
A good result, considering the overnight noise.
