I am using an Orion II powered by an Astron 35M PS, a Titan III model 417A
and a TT 238B antenna tuner. I can tune the O2 to any band and it keys
and
works on either CW or SSB barefoot with no problem. When I turn the T3
from
standby to operate in the QSK mode, sometimes the O2 will not key. This
is
an intermittent problem I have been chasing for several weeks. There are
times the pair will work together flawlessly.
The keying loop in the O2 menu is turned on. I have switched between
loops
#1 and #2, moving and checking the cables for correct connections on each
end when I switch.
The cables are original from TT and a continuity check shows them to be
good. I have also swapped these cables out trying another pair.
Two folks suggested I had a ground problem. All equipment was tied to a
common ground except for the Astron. I connected the minus lead of the PS
to the ground buss and for a while everything worked. Then the
intermittent
came back.
Next I made up a new braided ground buss. It runs from the minus terminal
of the PS, to the antenna tuner, on to the T3, O2 and is soldered to a #6
copper wire hooked to 3-8ft ground rods. The total length of the ground
bus
system is <10 feet to the 1st ground rod.
I have done a master reset on the O2 three times. Sometimes this seems to
solve my intermittent ... until I really want the amp on.
I am open to any suggestions on or off the reflector.
