GE Ed,
HG> When I had it going the local club decided to close down the packet

EV> I was wondering if the circuit used IC's or XSISTORS only or did it

It's completely solid state with, IIRC, one IC programmed for channels
and frequencies and another IC plus transistors. On the additional board
for mic/AF amplifier two more IC's.
EV> Is the Schematic for it on some Web Site?
It certainly is but right off hand I don't recall if the source was the
german CQ DL or UKW Berichte (english VHF Communications).
I usually prefer the german version if the publisher is in Germany aince
I get the contents faster than awaiting the translated english version.
EV> I ain't built any circuits for ages but I would like to see the
EV> Schematic for the Rig You built for packet radio, and later added
EV> Audio to it (for A.M. I suppose?).
I certainly do have the magazine that contained the description if I
only knew which one it was. I'll send you a note when/if I stumble on it
