[Premium-Rx] WJ DRX-308 and WJ VM101 for sale

[Terry O']

These are parts of various sales configurations of the RS-160 system.  
The VM-101 creates up to five markers for the tuned frequencies of 
handoff receivers on a 21.4 MHz spectrum display.

The RS-160 system was often sold with the RS-168 and the VM-101 created 
marker dots for on the RS-160 SDU (typically an SM-7301) for up to five 
receivers in the RS-168, allowing a handoff receiver to be quickly tuned 
to any pip that pops up on the spectrum display.

I have one of these systems in operating condition and it is pretty 
slick considering that this is 1970s technology.  I haven't tried it, 
but the VM-101 might work with any 21.4 MHz IF receivers that have an LO 
out and any 21.4 MHz SDU.

The DRX-308 extended the frequency coverage of the WJ DRO series up to 
1000 MHz from the stock 300 MHz.   It was often used with the DRO-308, 
but I suspect it is a repackaged  DRX-1000 and would work with a wider 
range of DRO readouts.

Both of these units are mentioned in the RS-160 context here:

I haven't written it up yet, but the most famous international incident 
involving an RS-160/RS-168 system was the recording President Ronald 
Reagan made public of the Russian MiG pilot talking with his commanding 
officer about the Korean Airlines passenger flight KAL-007 before it was 
shot down.

Best,
