[App_rpt-users] needed: radios for VOTER system testing

I am planning on doing some testing of the VOTER system here in my local area and have chosen the Madera Country Sheriff's main channel as the source of radio signals (156.240 MHz, 5Khz dev). I need to find a source of 5 or 6 Maxtrac or Radius type radios that have 16 pin connectors (so that I can get discriminator audio out of them). I dont even need them permanently, just long enough to do this testing. It would even be okay of they have non-functional transmitters, since there will be no transmitting done related to this testing (I am just testing the receiver voting stuff). Does anyone have such equipment available for this purpose? Thanks. JIM WB6NIL
