Low Receive


Paul Werz
 

Noticed recently my receive was dying? My 101 s meter doesnt move unless its a real strong? signal? I notice a signal from someone giving me maybe 2 s units and my other rig shows 10 S units? What should I be looking into . Any help is appreciated


 

Since it is a fast acting event... the?first thing I would do is replace the receive first RF amp.?
Q1 dual gate mosfet.?
3N211 transistors are still easy to find.?
But any decent, four leg dual gate mosfet
of that ilk.. will tell you if it’s bad.?
I doubt the receive line fuse is blown, as others might suggest.?

The best test will be replace the high frequency module PB1181.
Year ago I saw an exotic problem, the R13 off 1k was damaged or with wrong resistance.
A good idea is measure voltage over transistors leads.

good luck

This is exactly what my FT101Z is doing <see thread elsewhere on here> - only difference perhaps is that this happened suddenly with me.? Assistance from others on here has been much appreciated.? I would be interested to hear how you eventually fix your set....
