Re: Zetagi 131p
The resistors are directly solderd to the antenna socket. So it makes me no wonder why it does behaves like that. It is a design fault or cost effective. Maybe both...

Re: Zetagi 131p
Mine's weren't. I had a pcb there. Regardless , the position of that switch shouldn't affect the RX. I might have another look at the images I have to see if I can see , or think of anything.

Re: Zetagi 131p
Here it is. In HI position the RX signal has to pass through the resistor. In LO position the resistor is bridged.

Re: Zetagi 131p
That's only on TX. The relay isn't energised on RX , so the resistors do nothing. Have a look at the diagram I posted. I think they're (131 and (135) the same.

Re: Zetagi 131p
In my old model the resistors are directly solderd to the input socket. Maybe a newer model is different?

Re: Zetagi 131p
Yeah. I'm now looking at the diagram on P1 that Claude posted. It looks different. On HI both resistors are bypassed on RX and TX . But they're switched in on LO on both TX and RX.Is your RX being affected on HI or LO ?

Re: Zetagi 131p
That's not the 131 Claude. It's the 135. You already posted the diagram for the 131 on page 1.

Re: Zetagi 131p
According to the schematic posted earlier in the thread the 180 ohm resistor should be one watt

Re: Zetagi 131p
is it ok it is 2 or 3 w because i have a little trouble finding 68 and 180ohm metal film resistors.
