Re: FT-101ZD MK2 poor sensitivity ..


 

You can do some easy initial checks without taking anything apart. Hook your receive antenna to the rcv ant jack and see if you get normal receive. If you do, check continuity, with power off, between the centre terminals of the main antenna jack to the rcv ant jack. You should have low resistance path here through the lamp and the antenna relay.?
Let us know the results and we can go from there.?

Best of luck

Thanks Chuck,

I need to get oriented with the schematics and the overall layout / functionality of the rig. It's quite a bit of components in there ...
It shouldn't be too difficult to trace the RF input signal. But unfortunately the bulb fuse is fine ;)

Which manual are you referring to ? I downloaded quite a few of them.

I removed the upper casing and the rig looks quite clean inside. It also has the optional CW filter it seems.

I couldn't get to the valves but they're all NEC.
