K2 #4768 lives!
Finished the Tx section Saturday night. Only problem was a faulty relay
(K8) which was refusing to change over so 80m was deaf and had 0 power
output. Got around the problem by substituting one from my K160Rx.
Tricky things to get out from those plated through holes when you can
only get at one side of the board!
Built the SSB option last night. Sounds good, and the NB option removes
the QRM from the sodium vapour streetlights nicely. The one in front of
my house is very noisy during its warm up, not so bad when it is hot.
Checked the filter bfo settings at lunch time, had a tune around 10m and
heard M5AFD calling CQ, called him back and logged my first K2 contact,
10W USB.
I'll arrange a local sked later in the week to fine tune the TX audio
settings.
Now for the PA, DSP and ATU options.
BTW - you can get 20W out of a K2 if you forget to remove C167 from the
RF board during the SSB option installation carrier balance operation. ;-)
