I disagree with all the other posters who said this is possible and easy. This would be easy with an ID-800 or ID-880; they do not have an internal GPS, and rely on a serial NMEA feed from an external GPS. The IC-2820 has a GPS inside the radio (on the UT-123 D-STAR board). What you plug in is not an external GPS - it is just a GPS antenna. What you want to do would require either simulating the RF transmission from several GPS satellites, or injecting the feed into an appropriate place inside the radio (assuming it uses serial NMEA internally - I don't know if it does).
If you want to send and receive position reports via a computer, then this is simple and can already be done, but it sounds like you want to use the radio's GPS features, which is a different matter. 73, Brian VE7NGR On Fri, 2010-02-19 at 16:09 +0000, jkvochick wrote: > > I have a 2820 installed in a place where receiving a GPS signal would > be very, very, difficult. > > Sadly, without receiving a valid GPS signature, some of the other cool > features, like distance to station doesn't work. > > Since this radio is installed in a fixed location, I was wondering if > you could inject an appropriate rs232 signal from say an Arduino > microprocessor board, so that the internal units believed they had > valid psiiton data? > > Jim WB8AZP > > > > >
