** How do you delete your own post?? - It looks like this is interference from somthing at night in my driveway and not during the day! **

Hi All,

I have a Puma Defender 2015 with a GME built in UHF (4500) - works well with no issues.

I have a GME handheld (6150) held that works OK with other people's radios (based on radio checks)

If the 6150 is transmitting I get intereference on the 4500 - a low level frequency sound is output on 4500 - the Alpine sub also gives out a 'short sound burst' on end of transmit of the 6150.

I have tried hi and low power settings on the 6150.

It looks like the same fuse (front 27) is used for the Alpine system and the 4500 - is that an issue?

Also noting that when the GME was installed I also had a FM Aerial installed on the bullbar - not sure if this is part of the problem - although removing the FM aerial whip only makes a difference to the FM tuner reception.

Thanks,
Col.
