Hi Julio,

I am convinced that there is nothing wrong with your IC-7800. It seems
to me that the active antenna is either faulty or a lousy design. You
may wish to return it for exchange (or refund!)

The "muting" button does not change anything in the RF signal paths. You
will need an external switch such as the KD9SV Front-End Saver to
protect the receive antenna input when using dedicated receive antennas.

My favourite QSK station was ZSC2 on 500 kHz. (Yes, I actually got to
operate it once!) The control point and receiver site were on the coast
about 40km south of Cape Town, and the transmitter site - with a 15kW
Marconi MCW (A2A) transmitter feeding a great big wire array via 600-ohm
line - was 50km inland from the control point. There was no
hot-switching problem at all, and no risk of receiver damage either. The
inter-site link was a leased Post office wireline facility. 

Cheers for now, 73,
