I received a TT 422 HF Amp a few weeks ago. Everything seems to work
well but I found one problem that maybe someone can help me.
When I go to 40 meters the SWR between the rig and the amp is about 2.2
to 1 at 7.000 and down to 1.6 to 1 at 7300 KHZ.
All the other bands the SWR is flat.
The SWR is present even when I am on the dummy load. 40 meter antenna
My Question is - Should I just order a new board from TT? It looks
pretty easy. But before I do, I just wanted to see if anyone else had the
problem and what was the solution. and yes the 15/10 meter input board
