SM50 Constant Open Squelch
Posted: Mon Sep 08, 2014 8:04 am
Hey Guys,
Working on an sm50 VHF that has an open squelch problem. The radio is programmed with TPL in Tx and Rx. The Rx light blinks constantly and if the radio mic is removed from mic clip there is constant noise from the speaker (as if in permanent monitor mode). The radio receives fines and when in mic clip the squelch opens at about -119dBm with the proper tone. The radio does transmit but has no transmit audio. Have tried different mics. Not sure if the two problems are related or not. I have disabled all of the buttons on the radio to make sure its not somehow getting into constant monitor mode.
Any ideas would be much appreciated.
Thanks
Jamie
