I had TVI/internet lockups running a K3 into 80 & 160m wire antennas with U-verse. AT&T swapped out the modems numerous times, had three different models but no joy. Had their 'top techs' on the problem.
At the time, the 'net was filled with U-verse TVI issues. Switched to cable and no further problems. Lots of folks are using U-verse without a TVI problem, but it never worked very well here. -- Mike Flowers, K6MKF, NCDXC - "It's about DX!" > On Aug 25, 2017, at 4:16 PM, Fred Jensen <[email protected]> wrote: > > Does reducing the power change anything? > > Is there an inherent issue in the K3 which might attribute to this symptom? > > If there is, I'm pretty sure it's never been reported here before.
