[TenTec] Tuning Rigs

[Bob McGraw - K4TAX]

I fully agree with Jerry on this one.  It should be a requirement for every 
ham station to have some type of reliable antenna bridge and a dummy load. 
Then use the bridge to adjust the antenna or the tuner and use the dummy 
load to adjust the amp.  Connect the amp to the tuner or antenna and you are 
on the air and no QRM generated.

Day after day on the nets that I participate the "tuner uppers" jump on 
frequency and twiddle and twiddle.  Oh the auto notch takes care of the 
heterodyne but it still sucks the AGC.  The FCC considers this deliberate 
QRM.  Ask yourself, are you operating legally?
