The RU-20 was produced in the Ex-Yugolsavia by RIZ under Collins license. In fact it is a PRC-515.
This unit is a good example of neat design and functionality. It just works. Only a few controls put you directly on the air. The antenna tuner is fantastic and tunes anything.
It is a 20W HF transceiver that really performs like a 100W rig.
I made a new Li-Ion battery for this radio, you can see the how-to on my channel: youtu.be/towhJoXaPNY
You can also modify the power output youtu.be/Vxm44d6K2KQ
