[TowerTalk] Tuner SWR won't stay down

[Tom Osborne]

Hi Roger.

Yes, I did try that. I disconnected the torroid from the circuit.  I 
think it is something getting hot but just can't feel anything that gets 
overly warm inside.  It does drift faster at high power than at low 
power.  I also connected the input coax connector directly to the 
capacitor and the output coax jack to the other cap.

I thought it might be the coil getting hot, but it is not even getting 
warm.   May end up scrapping it and just using the parts to build 
something else.  It is a real puzzler.  Thanks and 73
