I realize that there are a couple of posts on this subject - I would like to add another use-case in addition to EmComm (for which I think this would be VERY useful): Sailors on yachts that rely on HF for communications could use VarAC if it gave them the easy ability to send a position report without transcribing GPS coordinates into a message. Some yachters are using JS8Call for this currently, but if VarAC had a GPS connection, it would be a much more useful tool.

My purpose: to add an additional VarAC frequency choice which could be used for EMComm or other local purpose without 'hogging' the standard VarAC freq. - I tried adding 7.050.000 to VarAC_frequencies.conf at the bottom of the list - as did my test buddy - We both selected 7.050.000 and I started beacons. I also sent a broadcast text. - My test buddy received the beacon and test, but I did not receive his and I did not see his transmission on either the VarAC waterfall or on my radio's waterfall. ( I am using FT-991A). It seemed to work only in one direction. I suspected something on his end, but we could find nothing strange and when we returned to the standard 7.105.000 VarAC freq everything worked normally. My test buddy was using a Kenwood TS-2000 with SignaLink. - I tried again with another friend, this time using 7.085.000 ( avoiding some other common digital modes). Different test buddy and similar one-way results. Is there something else I need to change in settings in order to use a custom frequency in VarAC_frequencies.conf ? Thanks for producing such a useful tool! Rick Lovdahl KJ7ROX

I can see that I can broadcast to 'ALL' or to a specific callsign. Is it possible to send a broadcast message to a set of defined callsigns? That would seem to be a great EMComm feature! Thanks for an amazing tool!
