[QCWA] What's on your bench?

[Jeffrey D Angus]

A couple of weeks ago, I acquired a Motorola Maxtrac UHF radio.
These were new around 1994 or so.

Deaf as a post, no receive. I was tempted to not bother as it's a
mixture of discrete and surface mount parts, but being a bit
stubborn I took it apart to trouble shoot it.

Having decent test equipment is a plus.

Feed a UHF signal into the radio at 463.8500 MHz and use a
scope probe and a spectrum analyzer to follow the signal and
see where it disappears.

Well it made it all way down to 45.1 MHz at the "receiver sub-
assembly" IC. And apparently the 44.645 MHz 2nd LO crystal
died.

I ordered a new one. It arrived and I soldered it in this morning.

The radio is working good as new.

Looks like the used radio I bought to replace it is going to be a
nice spare now. It works too. ;-)

Some times you have a good day on the bench.
