Re: [TenTec] Tuner and amp

[Robert & Linda McGraw K4TAX <RMcGraw@Blomand.Net>]

Depending on the amp, the input Z to the amp will vary across the band. 
This is specially true on 160M and 80M.  The auto tuner takes care of the 
input Z variation of the amp.  I don't find that the output Z of the amp is 
in anyway reflected back to the radio.
