It does work.

md:beacon e 1
BEACON was EVERY 0 (disabled)


The LED illuminates every minute to Tx the beacon.

         I have done so in the past, but it's been several years.  At
this point, you know the TNC is doing what it should.

         I'm doing all this on memory, but it seems to me that the
KPC-3 would send a blank position if it was in GPS mode and didn't get
good data from the GPS.

         Does the BEACON work?  Set BText to something or other, and B E
1 or something, and see if it automatically lights up the XMIT LED ever
so often.  Don't forget to go back to B E 0 when you're done with this

         Uh -- I've already erased the original message, could you
resend your GPS settings, i.e. beacon timings, etc?
