That is MOST unfortunate!  It is important to operate in full-duplex
in Mode J-FM, and with the demise of the Icom IC-W32A, the Kenwood
TH-D7AG was the only HT available which had that capability. Every
other multi-band HT available commercially tries to be a scanner 
from DC-to-daylight, and that is inherently incompatable with full-
duplex operation.  I believe that the number of people who can't hear 
their own downlink has alot to do with the amount of chaos on the FM

Please, please, PLEASE!!  AMSAT-NA and AMSAT-*, lobby the amateur radio
manufacturers to make another satellite-friendly HT!  This is important
to the future of amateur radio.
