Richard, if you want to announce that you are operating
both a BBS and a KA node on the APRS frequeency
then put that info in your APRS POSITION COMMENT field
or in your APRS STATUS packet. That is what those
fields are for.
Do *not* also send out an HID packet EVERY 10 minutes
which is just useless QRM to everyone and everything
else on frequency. It is just an innefficient use of the
channel and was never intended for there to be HID packets
The ONLY reason APRS decodes HID packets is so that
you can use APRS to monitor OTHER channels and see
what is out there... HID packets should not be on APRS.

Bob, this seems like another instance of where we disagree. In most
would agree with you, but I run APRSDos, and I re-enable HID manualy
time I re-start the program. WHY?
Well, you've said many times that APRS was designed for "real time
operation. It's not a far jump from "tactical" to "emergency" use. I
station set up to be useful during a total loss of commercial power.
radio and TNC will be powered by a 12v size 27 "deep cycle" battery.
computer that runs APRS will not be powered.
I have set my TNC's mailbox to be available, and set the TNC's KANode
well. Both of these could be quite valuable during an blackout when
"normal" communication channels are out. BUT if I have HID set to off,
will folks know that this resource is available? As a "backup" I have
the Beacon to once every 60 min and to use the standard APRS "quit"
(somewhat confusing during 'normal' times, but very valuable during
