[1000mp] Receiver Attenuator - defective

Sat, 20 Dec 2003 18:01:57 -0200

Gentlemen

I have the same problem reported in the emails below. Per diagrams probably
resistor 1151 (47 ohms) opened. Anyone could give some tips on where these
resistors are located, what a type of resistors and what to expect when
replacing them.

Thanks PY2XB

Exactly.

You have blown a few resisitors in your ATT switch. It's quite troublesome
during the contest and they are easy to replace. They act as a sort of fuse
so to say.
