[Dstar] IC-92AD & GPS Mic interaction and intermittent screen fault

[Nik Presser]

G'day all,

I wonder if anyone else has had the same intermittent fault that I've been having, as I'm reluctant to send it back to Icom unless I really have to (because I love it and would hate to part with it for a couple of weeks). 

On occaisons, maybe a couple of times per month, after powering up the radio (IC-92AD with GPS spkr/mic) and usually activating the GPS receiver (via the button at the top of the GPS mic), the screen goes blank after about 5mins and randomly flashes a thin line across the screen. Nothing will reinstate the screen apart from turning the radio off then on again. From here it behaves normally. Warm starts of the GPS don't seem to worry it. It seems to be on rare occasions, perhaps the cold-start of the GPS receiver triggers this fault. 

When I'm using the radio without the GPS spkr/mic connected, such as either on it's own or an Icom headset (via Icom switchbox) via an Icom Y-adapter cable, the fault never occurs. So all of this is pointing me in the direction perhaps there's something happening with the GPS spkr/mic that once the GPS cold-start has finished it's aquisition cycle, that it's causing an issue with the radio. Warm GPS starts seem to be ok. On very rare occasions, not even turning the GPS receiver section on at all will produce the fault. 

This intermittent fault only occurs once and then never to be seen again for the remainder of the day. It's a fault that I'm resisting annoying Icom about unless it becomes a regular event, although because I've parted with quite a few dollars for this system, perhaps I should send it in while it's still within warranty.  Has anyone else had an issue similar to this at all??

Cheers,
