[Milsurplus] Russia vs. US

[Ray Fantini]

The latest project around here has been a Russian R-107 transceiver; you
can see it on my web page at www.ka3ekh.net under project of the week.
In working with this radio and the older R-105/8 radios I see many
similarities with the SRR-11/13 radios. Yea, I know they are completely
different radios one being shipboard and the other a field radio but yet
they both use micro print optical displays, cast aluminum chassis with
molded cells for isolation and peanut tubes in removable circuits.
Anyone have any idea how two different countries produced radios using
some of the same ideas?
