/KAT100 on 160 Hi Current
Date: Thu, 07 Dec 2006 10:42:56 -0500
Hi Julius,
Both my K2/100s, #4970 and #5570 exhibit excessive current draw on 160
meters, as indicated by the ammeter on my 30 watt Astron PS. It gets up to
27 or 28 amps. I use a 30 amp fuse. In every other respect, my two
K2/100's
Fraser,
What is the power level at 'full power'? I have seen K2/100s that could
easily develop 160 watts on 160. To be consistent, measure the current
drawn from the power supply while the KPA100 is delivering 100 watts to a 50
ohm dummy load. All other comparisons are filled with unknown
Thanks Tom!
I checked my second K2/100 on 160 into a dummy load
and it looks like it draws about 18A at 12.5 VDC.
So I'm guessing I miscounted turns. Will check it out
over the weekend, assuming 10 isn't hopping.
Cheers,
Julius

Hi John,
Do you use the KAT100 with yours? Or is it just
straight to the load?
I do see a lot of RF in the shack with my sniffer on
160. It seems like it is coming from the sides of the
KAT100. I'm going to experiment this weekend,
hopefully, taking the tuner out of the line altogether
and see

John, Julius,
The normal thing to look at in a high current situation is the low pass
filter. Check both

Just to muck up the discussion a bit more.
