Here's the good news though. Â If you have a
current igate on 2m, you can replace the
computer with a UDR56K, attach a USB-to-Serial
cable  to the TNC and radio to continue to
service the 144.39 net, while offering 9600 baud
or better APRS on the UDR56K's 70cm radio. Â
Then you would have a dual band igate with less
power requirement (by loosing the computer) and
a much smaller package. Â Attach a diplexer and
dual band antenna and you are ready to go.
