Hi folks.
Just a quick question.
I have a trb-x3 echo board that up until recently had endless echo if wanted.
It has now gone funny where the endless echo no longer works.
I’ve read the instructions over and over and can only see the set up section shorting coach shield and j2 black wire temporarily to set.
Anyone had this issue.
Many thanks

    Coax question. I just put up a new Sirio monsoon base antenna with 100’ of rg8u coax testing with myMFJ antenna analyzer shows 1.4 swr at 26.965mhz and a 1.1 at 27.405 mhz . When I checked the ohms it’s steady a 30 ohms across the entire bandwidth.
  • @ Geoexplorer69:
    Is 30 ohms worth worrying about in a 100’ run of rg8u ?
