Thanks all for discussing the post for my TS-120.

I had the radio open to torque down the band switch knob. For some
reason there was a wire that had been cut which had something to do
with the 15 MHz WWV/ JJY circuit.

The radio with the wire "cut" would draw about 15 amps in the WWV/JJY
switch while transmitting but would not put out any RF power. I did
not keep the key down very long, in fear that what ever was drawing the
current would be destroyed.

So I reconnected the wire and very little current is taken if the key
is pressed now on JJY. My thoughts is that someone was trying to get
the wwv/jjy switch to transmit as I can see on the schematic that is
wire disables one of the radio's RF sections. Maybe a possible mod to
get up to 18 MHz.

Since no power is radiated, there must be another tuned-circuit that
prevents any RF.

I was listening to the 20 meter band today, while the s-meter was not
giving the same signal strenght as a reference FT-757, the TS-120 could
copy every weak signal the 757 could.
