Re: noise

 

Thats good John,

Now unplug the antenna and just touch the antenna ground to rig rear connector ground.
Nothing should be heard on RX.
If you hear AM signals or noise - probably the socket to board may be an issue or a ground loop.

I have had a similar problem when my jumper cable from rig to SWR meter was frayed and ground
was open.

The antenna ground should be isolated from ground of other rear inputs/outputs. They are all connected
internally on the board.

Hi Raj,

yes, I understood. From the board to the antenna connector is correct.
I?€?ve checked for continuity and for any shorts in the connection, but all seems ok.

I'll keep trying - and double checking the connections!

Hi John,

Sorry I meant from the board to the antenna connector.

Check with a multimeter on beep continuity if the connections are proper to the connector.

Hi Raj,

I???€??ve double checked and just now checked again. Centre pin to antenna and shield to ground - all correct.
