Put in verbatim what I typed and showed. [Freq MHz] is what tells the radio to tell APRS what to display. If I am on 146.460. 123.45 etc that will be shown in APRS. I don't really know how APRS.FI or anything else interprets the data.I have a couple TMD700a's and don't see that they support this functionality - but they might. :) If I remember will give a try later in the day when I get home to see what I can see.
@1Louder - point of clarification. Your raw APRS data shows no space between the frequency and the - (dash) but your screenshot above looks like there is one in there. Does the space between the freq and the dash exist in the radio setting and get stripped out somewhere? Also I assume that "[Freq MHz]" is a placeholder for something like "146.535MHz" or does the radio replace "146.535MHz" with your non-data band current freq?
