Anyone have one of these? Ive just bought one with no manual. What aux
antenna should I be using and where should the aux antenna be located in
relation to my main antenna.
Secondly, what is the procedure for tuning the gain,phase1 and phase2
controls.
Try to get teh AUX antenna as far away from your main antenna as
possible: I use a 12.5m wire fed via a 9:1 Un-Un in my attic.
I'd suggest setting the gain to about 3/4 open, then I'm afraid it's a
question of fiddling with the controls ONE AT A TIME until you
minimise the interference. Tuning can be quite sharp!
And just in case you kill it by applying HF at the wrong moment: the
FETs are J310s...
