Merging is a problem, because if you're going to have a translating digipeater, that doubles the traffic on the output side from all the dual-protocol stations. And it would be quite difficult to write a good OpenTRAC<->APRS translator, because some single OpenTRAC packets map into multiple APRS packets, and not cleanly (for example, how is an OpenTRAC sub-entity represented in APRS? how are APRS Telemetry packets mapped into OpenTRAC entity values when there is no fixed meaning of APRS telemetry fields?). I know this, because my YAAC program speaks and receives both protocols, and has a tough time coming up with consistent data display to end-users, and that's just doing the merge at the presentation layer, rather than translating and re-transmitting.<br></div><div dir="ltr" data-setdir="false"><br></div><div dir="ltr" data-setdir="false">And promoting OpenTRAC still doesn't deal with the existing hardware base of APRS-only devices (ex.: Kenwood D700's don't do OpenTRAC natively).

Icom’s conscious decision to not include analog APRS in their radios baffles me. And there are other manufacturers such as AnyTone that are limping along with half-rate implementations of APRS that do more to harm the ham community than help. Thankfully they seem to realize the error in their ways and have been making a slightly concerted effort to remedy their sophomoric attempts with the original AT-D878 and AT-578 with the recent release of the AT-D878UV2 Plus and the AT-D578UV3 Plus - both still leave a lot to be desired. </span></p><br clear="none"><p dir="ltr" style="line-height:1.38;margin-top:0pt;margin-bottom:0pt;"><span style="font-family:Verdana;color:rgb(0,0,0);background-color:transparent;vertical-align:baseline;white-space:pre-wrap;">I think we can all agree that the APRS standard stagnated and has largely remained the same for the past several years.
