hi everyone,
i am having a weird problem w/ a gm300.........i have it programmed to the freq and pl's i want. but when i key the mic it does send a signal but my portable cant hear it........i see the s meter go up on the portable but no audio, as if the gm300 is not sending the pl tone.......if i take of the pl's on the portable it all works fine..............i tried it w/ a maxtrac and that works like it should. just the gm300 does it

any ideas?

Check your programing again........this is most likely the cause.

i triple checked........freq n pl are right........i even tried diff pl's.....could there be any onther place in the software which could inhibit the pl's?

otto

Check for PL Inhibit programmed into the accessory connector. If its there, change it to NULL

yea i looked it is null

man i am lost
...........maybe te pl board is shot

Are you using DPL? Is it a non-moto portable? If so, try programming it with inverted DPL.

Other than that you'll probably need to look at it on a service monitor.

no i am tryin to use 192.8...............it recieves the pl ok ........dont seem to transmit it tho......grrrr got me frustrated

anyone have any ideas?

Well, there is the reference mod adjustment on the RF board, perhaps somebody turned it down. It's the blue pot closest to the front of the radio. The pots usually have a magic marker line on their side from the factory, you can tell they've been adjusted if the mark doesn't line up.

Also the GMs have a problem with the feedthrough connector between the logic and RF boards, see my post here: http://batboard.batlabs.com/viewtopic.p ... eedthrough
I've never seen it cause the problem you're having, but I suppose it's possible.

thanks........i'll have a look at it

well i tried everything i could...........it just wont tx the pl..........i turned off all signalling ....sequences all i saw in reference to tx.........i tried the logic board connector to........how can i reset the entire radio
maybe that will help

otto

i found it weeeeeeeeeeee.........it was an internal jumper.........go figure ....i was playin around w/ the jumpers (i figured i had nothing to lose) and poof the pl was transmitted.........thanks for all youe idea's guys i do appreciate them
