I have a GME 3400 2-way, complete with a 4.5db aerial. I can receive "loud & clear" from others, upto 12 or so klms away, but when transmitting, my signal is difficult to receive by others that are more than 1.5 to 2 klms away. The problem is consistent whether I'm in front, middle or tail-end-charlie. Aerial is mounted half-way along left-hand mudguard.
It has been suggested that I get the signal tested. Does anyone know of someone that can do this in
Sydney - I live on the southside. "Outsiders" often refer to it as "the shire"?
The radio has been installed for about 5 years, but only recently become aware of the problem.
Thanks
Brian

Hi Brian,
first I would
check all connections, cable and antenna for breaks, loose connections, dry solder joint, and the antenna mounting point. Without using "techno jargon": When you transmit, you are putting out "power" along your cable and antenna, so any weak point it will break down. On recieving, you don't have the same "power" in reverse, thus no
breakdown. Similar principal to your 12 Volt system: poor connection, put a load on it, and it fails. same with your radio. Hope this helps.

I have had a somewhat similar problem transferred my old radio to the new car was talked into a windscreen aerial ie only 2 stripes on the screen as the
Perth dealer claimed to have had good success with them . I could get the incoming signal fine but could not transmit more that 2 k's and that was only in flat country .
Spoke to my bloke and he will alter and put an aerial on

Thanks new boy.
Hopefully my problem is as "simple" as an aerial issue.

i had exactly the same problem with my old GME
uhf radio, my problem was the mic lead. GME are known for this problem when they get old.
the guys at Olbis just down the road from me got a new mic out of the packet and plugged it in and checked with the guy in their workshop, radio worked fine with new mic. plugged the old one back in and it was abit ordinary, wiggled the mic lead around and it was abit worse. a new mic has fixed my problem, might be same for you.
think it was about $50 for a new mic.

when i say my old uhf, i mean it's about 10 years old and in it's second 4wd vehicle. so not to bad for a uhf i reckon, and now with new mic it's still going strong.

My 3400 had the same problem.....the mic lead wires had snapped off eventually from flexing at the mic, though i never knew until one day i did a "radio check" in
Brisbane and nobody answered. :-)
Seems i had been listening for several months yet couldn't transmit.....also explains why my quick response to a couple travellers and truckies went unnoticed ("hey mate, your tiedown ropes are dragging on the road" etc)
I pulled it apart and redid the connection which fixed the transmission issue.
