Hi Doug and Stephen,
I did that too. The 958 wouldn't quite cut the mustard. And, I found that the Tx
and Rx frequencies were slightly different, using the 958A in Rx as a
super-regen. So, I designed up a base station with those different frequencies
in it and then all the hand-helds could talk back to base. I used a 3S4, as I
recall, as the detector/AF amplifier/modulator in a reflex circuit. Crikey, that
brings back memories! All in a box about 9" x 3" x 1.5". The biggest part,
apart from the 19" antenna, was the 67V5 battery.
I think I used a pair of 955s and a pair of 3Q5s in the base station. Simple
half-duplex - we hadn't heard of repeaters, then. Used a piece of rubber hose
to fit and remove the acorns from their sockets.

Funny thing, I used to make walkie talkies (2m)
using 958A's back in the 50's and just soldered right to the pins. Never
damaged an acorn tube until I tried using a socket. :-)
