Ø  By the way, the D700 TNC is a REALLY mediocre-performing device as well.
   In several test runs, Direwolf and the UZ7HO "Soundmodem" software TNCs
copied almost THREE times as many beacons as the D700 hardware TNC.

The problem in this case was what was doing the transmitting?  A typically
non-tweaked packet transmitter can be FULL Scale on a kenwood and some
other TNC’s and not decoded.  But a properly balanced packet can be fully
dedoded on a kenwood down to only 3 bars on the s units.

The problem is that 90% of all packets on the air were never properly
tweaked for optimum performance.  Just put it up and it works!  (but fails
miserably in weak signals).

Repeat your test with a kenwood doing the transmitting (known factory good
signal) and a kenwood doing the receiving and you will see an order of
magnitude improvement in performance comparted to most signals on the air.
