Only if you're running in APRS mode.  In "TNC" mode the TXD is adjustable.
 You also get KPC3+ or better digipeater controls in TNC mode.  In "APRS"
mode you only have 4 simple aliases for digipeating.

This one little D700 on a hilltop has sure opened up the 9600 baud network
in the Puget Sound region.

We still have yet to test what happens if a nice long, 250+ bytes, packet
is thrown at it.
