e.g. every 30 seconds delete oldest packet that it is holding onto, or
it could have a "high digi" mode where it will temporarily turn off
carrier detect if it detects the buffer is full so it could go ahead and
transmit, but you wouldn't want the buffer to be so large that it stored
packets older than 30 seconds or so.
If the frequency is busy enough at your 5900 foot site, perhaps the
real solution is to move the digi to a lower elevation. As the APRS
frequency gets busier in some locations, we may have to move the
high digis down to lower locations like cell sites and just have a
few more of them. Alternatively, you could leave your high digi
at 5900 feet, but use a non-standard alias so that it would be available
to people that had a reason to try and send a packet 800 km... e.g.from
up to 400 km on one side of the digi to 400 km on the other side of it).
Of course, with it that high, if the frequency was busy, the chances of
it successfully hearing that particular beacon would be low. High
voice repeaters are great. Only one person talks at a time, but high
digis (at least using generic aliases) really only work where the
frequency is relatively quiet.
With it being an OT2m, you could remotely enable the standard
locally used alias if it was ever needed.
