GB300 rx radio PL Muting problems?

Postby shadowman » Tue Dec 29, 2009 8:31 pm

gday all i have a GB300 here wich consists of two faceless m120 and a poverty control board behind a 19inch faceplate wich has 1 Mic connector , a on/off volume dial a few leds and a switch for TX/RX wich switches the radio in wich the mic connector is working for. im trying to use a PL tone on the RX radio as it has been set up as a repeater but it currently opens up for any PL or no PL tone at all wich makes it a little to public for my liking, usualy to fix this on the GR300 and other gm300/m120 wich have faces on them i use a RJ45 with two pins linked in the mic connector but this does not work for the GB300 so im looking for a alternate solution? any ideas ?
thanks all

You are close, the HUB, mic hang-up, must be grounded on the receiver radio.

Unless he constructed the shorting plug wrong, there should be a ground pin in the mic jack.

plug is correct , they work on REAL gm300 and m120 but because this unit has no faces on the radios and their is no mic hook pin on the plug on the 19 inch front plate. only ground ptt and mic audio im prety sure. so i need to find hook line the radio on the front pins or inside the unit on the PCB.
