I would check very carefully for a Coax failure or other short/Open in the signal path. I would then check the antenna with a second rig or receiver , if you have one available
Next check the k3 carefully to ensure that you have not inadvertently selected the wrong antenna port, RX antenna input input etc. If you have the transverter interface check to see if you can hear ok on the RX antenna input, this would help rule out the ATU Your wattmeter will not give meaningful power measurement results without a dummy load, even then the results will be a bit of a 'ballpark figure' Until you resolve other issues carry out your tests at a low power level (20W or less than 2W might be good choices) Also both the Low pass filter and the Surge arrestor expect to operate in a (near) 50Ohm environment but presumably the system is relatively close to this when functioning correctly ?
