Hi Tony, I have seen a situation where a section of thin aluminum plate was cut to fit on/over the original PL module. A Comm Spec TS-32 was placed on the Aluminum mount/plate with double sided tape and parallel interfaced with the original MSR-2000 PL module. The plate "stood off" from the MSR-2000 PL Module PC Board with classic threaded standoffs. Probably the 3/8 or 1/4 inch length 4-40 or 6-32 size were used.
Working from memory... I believe the original circuit only used the Decoder section (portion) of the TS-32 but I'm sure it wouldn't be rocket science to make encoder work (taking the encoder gate/mute on/of operation into consideration) on more than one CTCSS encoded tone. One might suggest a couple of contact Emails to the remaining Surplus Radio Dealers... I'd contact Ted at MDM and go from there... also posting a want on various yahoo radio groups like this one. cheers, skipp > "kt...@..." <kt...@...> wrote: > > Hello Everyone, > I'm in need of two 97.4Hz PL reeds for an MSR2000 using the TLN5073A duplex > card (one TX and one RX).
