Subject: [IC-7000] Ignition noise, please help
after a lot of research I purchased an Icom 7000.
after installing it in my Chevy Tahoe, I am getting S9 plus ignition noise on all HF bands. of course this renders the radio useless.
I have the radio grounded to the engine block. And my antenna mount is grounded to the frame of the truck.
and I have wired the radio directly to the battery.
I have disconnected the antenna from the mount in the ignition noise goes away.
this only occurs when the antenna is connected.
and of course I get the same results if I disconnect the coax.
also, I have tuned a 40 meter ham stick with a one to 1.5 ratio.
coming back to the radio an hour later without adjusting the ham stick,
I am getting a 4 to 1 ratio.
VSWR does not seem to be stable.
I am hoping the members of the group are able to help me with my frustrations.
thanks in advance Shaun.
