Anyone familiar with the Metheny Corp Madison, IN Model LJM-RB DTMF
decoder board? I have two of these on a used VHF Engineering RPT-144
repeater I picked up.

I would like to find the schematic for this board.

Thanks much,

-Jim

I'm looking for more of a similar item as this repeater board version...
I want more of the LJM 1 Metheny Corp. Long Tone Zero Decoders for '0" DTMF tone to active a remote speaker on any radio. I just found one yesterday at Cave City, KY Hamfest and I had been looking for one for several years. I had one back in late 70's or early 80's and it got away from me somehow. On the cover of the grey box it is called "STORM-ALERT" EMERGENCY DECODER MODEL LJM 1. If anyone has one to be rid of please let me know. 73 KA4ADF
