My old Motorola L43-GGV Base Station (TA190) just had a failure.

Most unique,  The old International transmit Crystal had  F-609 adapter pins attached to the standard F-605 case so

it would fit into an FT-243 socket. The adapter pin became unsoldered and caused a squeal on the

Tx audio. I pulled the crystal and one pin remained in the socket. I resoldered the adapter pin and the rig

works OK now, Maybe for another 10 years. All the electronics at Ice Station Zebra are unheated so it gets really

wide temperature cycling. Temperature cycling wrecks everything.

Put the crystal in a gold oven and you won't have all the problems!? If you don't have an oven, let me know and I will send you one.?Glen, K9STH?

Thanks Glen,

I have plenty of ovens.

The crystal was ordered with the F-609 pins, I don't really need the F-605's.

There could be some internal connection problem but since the first repair worked I am going to try for another 10 years

of failure free operation.

I still have quite a few of the 4-pin, and 6-pin, gold ovens left over from when I owned the Motorola reconditioned equipment facility for the south-central United States (from 1970 to 1979 when Motorola went out of that "end" of the business).? Most of the ovens are in boxes stored in the attic!?Glen, K9STH?
