Band Decoder & Antenna Switch

April 30, 2013: Remote Box Done!

On the bench .. Made in RD Congo 9Q


I plan to build a band decoders and HF antenna switch. For two radios, Icom 756PROIII and YAESU FT-2000. For Yaesu, no problem, Output data works fine. For the Icom, no other choice than go through the CI-V output rather than the ACC2 connector without WARC band voltage.
I will use the vacuum relays Jennings models RJ2B or RF3A.

Updated on time.. 73 Georges 9Q1EK - VE2EK - ZS1II
