I have a FTDX-3000D and the best general info I could find was not to exceed 30db on the RX port. How did you measure the voltage? I built a small square law detector to measure the voltage on my RX antennas during transmit and took some reading with full power just to be sure.

The problem is I measured about 1,5 V on the K9AY coax loaded with 50 ohms with 100W forwarded to the Tx antenna and I wonder if it is safe for the Rx part of the radio. With full power it would be several times more! I did not find requested information in the manual nor any of known Yaesu dealers has been able to answer my question. Going T/R in this configuration I can hear relay noise in the rig so may I assume all will be correct however a mistake would be very expensive. Can someone give me a reliable information about the safety of the radio? 73, Mirek SP5ENA PS. I realize perfectly that is not a good sign having so much power induced in the Rx antenna. _________________ Searchable Archives: http://www.contesting.com/_topband - Topband Reflector _________________ Searchable Archives: http://www.contesting.com/_topband - Topband Reflector
