Funny this should come up. I have a 3006 Wavetek that I bought for what I
guess is the going price (low end!) that doesn't work. Looks good, though.
Wonder if anyone who's now woken up to this has any ideas on fixing it. I
did replace a shorted bypass cap in one of the modules that was bringing the
power rail down, I guess I can handle that.
If anyone wants to help I can check on the remaining problem, which is that
one of the fault LEDs in one of the modules lights very very dimly but
enough to raise the failure line.
Overall symptom is output all over the place since it's unlocked.
Unfortunately although I have a manual I have no money to pay a professional
and have zero experience at gigahertz frequencies and no test gear and the
only gear I have that works at remotely those freqs is a TV receiver and
tnx es 73,
