I did a similar test using a dummy load (Mil-Spec 2 kW) with the KAT500
in line and carried on a QSO while watching all the meters. After
about 45 seconds the tuner went nuts and started a retune - with no
change in frequency etc.
Well, I’m hat in hand looking for some advice. Thanks in advance.
Configuration: K3, P3, KPA500, KAT500 to a wire. AUX cable used for control.
Symptom: K3/KAT500 loads fine into the wire with amp either off or in standby.
SWR goes high and no power out when amp is online.
Possibly
Ooh. Well, I hope it wasn’t punishment for “bending” the NAQP rules:
No greater than 100 W. Use of external amplifiers capable of more than 100 W
output is not allowed.
And yes, my KPA is not running while I play in NAQP...
OK, so please send me a copy of the fault table for evaluation. We will
OK Jack.
I believe in having fun in a contest. For me, antenna challenged, that means
running “high” power (500 W). It also means FYI that I use all assistance
available to me such as skimmers, etc. No, I won’t submit as multi op, since
I’m not. No, I won’t submit at all since I elect to
Due to recent experience, I have to wonder about the KAT500???
Do you have a resonant antenna or a high power dummy load you can go to
directly - removing the KAT500 from the antenna circuit? If it works
without the tuner in line - then you have likely eliminated the KPA500
as the problem.
Gary;
I’m sorry my attempt at humor struck you the wrong way. You would be surprised
at how many avid contesters forget that NAQP is one of the few major HF
contests where high power is not allowed. From out this way, high power would
help a lot, especially from the postage stamp sized lots
