Yes, this does help - your research is giving this feature some bones.  I've done a bit of googling on that sentence, found the generic layout for this message (below).  This should be easy to implement, we just need to figure out what is expected for Fields 3 & 4 (Communication Mode and Power Level).  Then we can get this on the dev plan.

 

        1      2      3 4 5
        |      |      | | |
 $--FSI,xxxxxx,xxxxxx,c,x*hh<CR><LF>
 Field Number:
1. Transmitting Frequency
2. Receiving Frequency
3. Communications Mode (NMEA Syntax 2)
4. Power Level
5. Checksum

Walter, this is cool!  I'm not sure what the communications mode setting is all about? There is actually a command to adjust the power output level of the transmitter?

Thanks a ton for looking into this!

I doubt many radio's will do anything with those values...but we still need to figure out what to put in there so our message can be properly formatted.  If you can find more info on the spec, please share - my googling hasn't turned anything up yet

Walter -

Rick at ICOM tech support (800 872-4266) told me while the A220 does require a complete FSI sentence for this feature to work, it only uses data from the first two fields (Tx freq./Rx freq.) and ignores the other 2 data fields (Comm mode/Power level). He further stated replicating the NMEA FSI string produced from a Garmin GPS product would produce the desired result. Although he didn't specifically say, I would think the proper checksum value would also need to included at the end of the string.

Sorry to dig up an old post but the search function was coming up dry.

Any updates to adding this functionality?
