momentary jt65 signal drops

Dave Danforth
Dave Danforth Member
Recently my Flex 3000 on jt65 will show a fattening of the sig on panadaptor.  This is accompanied by a reduction in vertical element of sig, power supply meter drops 6-9 amps and the power meter on the 3000 drops about 10 watts.  The monitor tone has a weird "swish" sound at the time this happens.. Thoughts?  Running powersdr 2.7.2

    Could the power amp be folding back due to bad SWR?

    Could be a drop in the sound card audio as well to the F3K, causing a drop in rf.

    How much memory have you got and how much is allocated to the swop file I think its called.......To speed things up, windows saves a lot of repetitive stuff to memory for quick access. Are you running other software at the same time which dont need to run excepting anti virus. Try removing any apps you have running on the task bar. Unless you have a super computer, you will need all the processor power you can get incl memory.
