[MRCA] Need Transworld TW-100 help

[jkarlow at comcast.net]

Al –

 

I looked through the parts I have here and found a box of new spares for the TW-100. Included in that lot is a new 100 Hz Synthesizer M5 in its anti-static wrapper. I removed it from the wrapper and it does show the 5.120 Osc Adjustment so this is probably what you are looking for. It has a green sticker on it with date 3-10-92. The M5 has been in storage here about 20 years. I no longer have a TW-100 to test it in so it is as-is. $75.00 plus shipment to your place.

 

Hope this helps,

Gang,

The 5120 KHZ frequency-reference output from my M5, 100Hz Synth, module is only about 40mV P-P even when disconnected from the rest of the radio. Manual says I should have 2,8 VRMS.  I've changed the oscillator and buffer transistors to no avail.  DC voltage seem OK.

Doe anybody have a spare module, or even just the 5120 xtal?

Any help or suggestions appreciated.  Yes, I have a message in to the guy selling modules on E-bay.

This is for my Flyaway that I'd like to get running for the MRCA Gilbert meet.

Al
