After a storm, and then some shadey guys ripping off our boats; I had to pick
upo some new electronics.

I picked up a garmin 498 sounder & Standard Horizon PS2000.

They both work fine, however, independantly.
When they try to talk (nema) is when I have a problem.

The VHF radio can read the position information from teh garmin. But the garmin
cannot read the information from the radio. (ie: DSC calls)

Garmin is telling me it "does work" and Standard Horizon is telling me that "it
does work" but it doesn't.

I have tried
DSC call
DSC position request
DSC distress

None of them make it to the gps, despite the radio picking it up. I have gone
over the nema wiring about 2 dozen times; so I fear it's a few hours away from
Garmin placing the blame on Standard Horizon, and then Standard Horizon placing
the blame on Garmin.

SO -- long way of getting to my question:
How can I test/see/read the nema sentence being sent from the radio to be sure
it's leaving the radio -- so I can send the gps in, and if it's not sending the
data, send the radio in?

Or, anyone have any bright ideas on what to try?

Thanks
