The following is the reply from Digi-Devices answering my query
to them regarding RF Interference (RFI) to the Digi-Panels.
I'm ready to "pull the trigger" and, as I think Dan Gregg said,
just not worry about the unit alarming while I may be talking
if the RFI reduction techniques by Johnny Bridges don't fix it.
I'm unsure what the difference between the standard unit (DP-104)
at $214.94 list and the "GMC" unit (DP-104J) at 209.95 is. I think
Rob can explain that!
I know that I will need the extended harness at $5 for mounting
on the dash, RV battery monitoring at $15, and engine oil temp
at $27.50 in addition to the regular charges.

Hi Mac-
Yes, the integrated circuits we use are very high speed,
and can be affected by ham radio.
We've never had a Digi-Panel harmed by it - they just go
crazy while the signal is hitting it.
We have rf filters built in, but they can only do so much.
Best wishes. Art Woodell

I have heard several reports that the Digi-Panel is severely
affected by signals radiated by ham radio transmitters in
the range from 3 through 450 Megahertz.
Are there any (specific or otherwise) recommendations
on methods to combat this effect?
Many of the folks in the GMC Motorhome group are also
ham radio operators and would appreciate any information
or advice you can provide on this matter.
