No Reception thru ANT1 or ANT2 but Yes thru XVTR

Craig Gagner · June 2021

I am running a Flex 6300 and today the radio suddenly has no reception through either ANT1 or ANT2 ports. I do get reception through XVTR port however.

Also, when I key the transmitter out through ANT1 or ANT2 with a dummy load at 1 watt I get a high SWR.

Any suggestions are most appreciated.

Best,

W7PHG, Craig

When my 6400 does strange things, like no output power, reset usually fixes it. Sometimes it takes a “factory reset” (white power switch light) to get it to work correctly.

Thanks; I tried a reset; that didn't work. However, I put a dummy load on ANT1 and a high SWR was returned. On a whim I hit the ATU button and the ATU made one click and rendered a low SWR. Everything seems to be working as should at this point.

Hmmm.....I'll keep an eye on it.

Thank You,

W7PHG, Craig

Can you disable your ATU and run for awhile? [I know you can bypass your ATU.] Are the antennas all low enough SWR to run that way? Perhaps a relay was sticking in the ATU??
