In a message on 12-03-18 Ed Vance said to Holger Granholm:

GE Ed,

 HG> When I had it going the local club decided to close down the packet
 HG> radio system. Consequently I added a microphone and speaker amplifiers
 HG> and had a 70cm transceiver.

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