[aprssig] HT-220 HT's for APRS

[Robert Bruninga]

Has anyone used the old motorola HT-220 HT's for a simple cheap
APRS radio? I found a box full of them in my garage. 

I remember doing one years ago, and the only rub was the lack of
a PTT relay.  I think I might just use some diodes and 1/4 wave
line this time?

What about XTALS?  That can really run up the cost.
