Topband: safely sharing an RX antenna

[Petr Ourednik]

Hi

it sounds like SO2R on the same band... Its interresting for me too. I
am using one solution in CQ160m in order to use 2nd radio for S&P but
its disconnected from antenna and grounded as same as 1st radio in RUN
during TX period. So I am curious what other TBers are using...
