Can anybody recomment a Crystal house?

[mountritter]

Can anybody that has worked on old radios recently, point me to a crystal manufacturer that can cut crystals for 2 older type radios?

One is the old Harmon "4R series railroad radio", which had modular and removable transmitter (33 TS-1) and receiver (28RS-1) modules. They each have removable "channel elements" that have a small circuit board inside. My application is to use the receiver modules and make a web MP3 streamer that will take two railroad channels and broadcast the content in stereo over "Shoutcast" or "Radio Reference" web streaming.

An alternative to the Harmon I have available would be to use an old Motorola "Railroad Mitrek", which has a similar arrangement with channel elements.

Can anybody point me to a source for re-crystalling these types of channel elements?

Thanks in advance.

have you checked with bomar or crystronics? it's been a while since i ordered any crystals but either of these usually can do it.

I would recommend bomar or icm on this list.

Oscillator Manufacturers, Crystals, Resonators, Oven Controlled Oscillators, QPL Devices

BTW: You should send out the channel elements to them and
allow them to temp compensate them after installing the crystals.

They always work better that way.

I've used Bomar on several occasions over the years and they always did fine for me. I don't know if they still offer the option where the longer you can wait, in weeks, for delivery the lower the price goes. Not by a whole lot but it's still less expensive than "rush" delivery.
