Working so far: Analog APRS (beaconing only), 220mHz, Brandmiester SMS, direct entry TG and other cool stuff. May have to get the Anytone mobile radio next.

For direct entry, change the hold time for manual dial TG to "infinite" in the CPS. Then a long zero keypress and a # keypress to directly enter a TG number - doesn't need to be in your TG list.
220 hack may be detrimental to the low pass filters in the transmitter. I've been using 220 in low power for my Allstar node - no smoke so far.
Anyone else hacking on the 878? The SMS stuff is slick....

Dangit Dave, you're messing up my radio budget.
