Shouldn't. I believe the DSC signals are sent over channel 70; the transmission itself isn't really different than voice communication, except that the generated broadcast is a digital signal rather than an analog audio signal. If voice transmissions work, DSC will as well (assuming the DSC portion of the radio is working.)

From the reported tests on the Nautilus Lifeline handheld, they were able to send and receive voice calls for up to three miles, but the DSC traveled just over 12 miles, and those tests were performed at water level for the handheld.

We are lucky in that our coasts here in the USA are set up with Rescue 21 which is monitored by the Coast Guard. A large majority of even the remote coastal areas are monitored.

This is from iCom's Handheld DSC website

You can also request the position coordinates of any radio listed in the address book. The other radio will reply with its latitude and longitude, and its distance and bearing will appear on your screen. The radio can serve as a GPS and set a course to the other DSC-equipped unit. (DSC doesn’t provide continuous tracking, so if the other radio is moving, you’ll need to make multiple position requests to get the current coordinates.)

iCom support say the M91D isn't programmed to send requests despite what it says above

That seems to be misleading then

I think Scot said a dealer can enable position requesting on the M91D with some programming cable magicry.
Can't think why it would not be a standard capability though.

Interesting.... iCom have replied to me saying they have removed that text from their website and are consulting with iCom Europe technical department to see if this feature can be enabled. They'll get back to me in a couple of days.

Maybe you should get a job with them

I have just been on the Ofcom website and got my dsc portable license with mmsi no etc.

I was very shocked how easy it was, I thought I would have to do another radio operators license as I did mine in about 1990. But it seems not, well it let me have the licence anyway!

Now I have to save up and look for a decent handheld with the gps built in, most now do but not all. So Im told!
