[aprssig] Displaying Operating Frequency

Nice idea, but it does rely on the rig's actualy being able to be
interogated as to the operating frequency over some sort of remote
control.  Many (most I'd suspect) cannot do that in any way shape or
form, except with extensive hardware modification.

As someone else said, do you want HF, VHF, mode, power, etc etc.   The
"Status" packet could grow and cause congestion of it's own if not

Also, please appreciate that many (most?) ham's don't go and buy the
latest and greatest radio each year, however nice it might be to do so.
They/we just do not have the funds for that.

However...   A version of a tracker, but for home stations, with the
ability to have a keypad stuck on it, or driven from the shack PC (I
think it safe to say the PC or similar device is in a high percentage of
Ham stations, even if not actually hooked up to a radio.)  Then it would
be easy for an operator to tap in whatever frequency or channel they are

Even a dedicated bit of software, with it's soundcard modem and another
VHF radio, and/or net connectivity could do the job?

You could expand on this, and have a PIR sensor in the shack, so that
any "Live" individual in there triggers that, and so updates the
stations presence settings.  So long as you don't end up sending the
status of the family cat jumping up onto a warm radio for a quiet

I suspect it's a lot easier in practice to use the Voice Alert facility
that some APRS equipped radios have.  Not that many people use that,
especialy here in the UK.
