Recently got my Heathkit DX-40 working, and aquired a Johnson
T/R switch to get a 50 station back on the air...Two questions that
I'm hopeful one of the group will be able to help me with...# 1 the
Heath DX-40 has great output, but when loaded, and keyibng on CW, the
plate current always drops about 15 to 20 ma...in other words if you
key it, it will go up to 125 ma, and then drop down to 110 ma or so
almost immeciately, with a corresponding drop in power as indicated
on an external wattmeter....plate voltage on the final DOES NOTdrop as
current does.
#2..The Johnson T/R switch works great, and all voltages are right on
but I don't think I've ever seen a piece of equipment with two tubes
run that HOT...is that normal...Appreciate any ideas and opinions...
Thanks...Bob
