[Collins] Off Freq... Need Collins XTAL's

[k1kq at motorhomesusa.com]

Hello Folks:

I'm looking for the USB XTAL's for my 32S-1 and 75S-1. They are off frequency and I'm chirping like a bird on transmit. 

We have determined that between the xmtr & rcvr radios, one XTAL was high and the other is low netting a total difference between the 2 XTAL'S of 104 cycles. We tried to put a pot on the crystal in the transmitter to pull it down to 456.350, but no joy. I would be interested in hearing from anyone who has had the same problem with an S-Line.

In the mean time, I'm wanting to hunt down 2 XTAL'S to possibly replace them in both the xmtr and rcvr with good ones. The LSB XTAL's where also off, although not as much, so I may also need a pair of them.

They are...

- USB - 456.350 khz - Part No. BL290-8706-000

- LSB - 453.650 khz - Part No. BL290-8705-000

I seem to remember an outfit in Council Bluffs, IA and or Bellvue, NE that was supplying the Collins Crystals. I'll post this to the Collins reflector, as well.

Thanks in advance for any help, suggestions or parts you may have.
