[TenTec] Tuner

[Steve Hunt]

At 3.5MHz, the SWR(50) of an 80m dipole cut for resonance at 3.8MHz 
could easily be 12:1 or higher. Depending on the length of the coax, 
that can present impedances at the tuner that will be well outside the 
matching range of a 238.

I just can't seem to find the combination.  I'll try your suggestions and watch the meter closely as I may be missing the sweet spot I'm looking for.
