[Yaesu] Mark V w/Linear Amp Problems

[James C. Hall, MD]

Hi Javier:

I see this all the time with my Mark V to a Alpha 87A to Ten-Tec tuner 
and out to the antenna via Array Solutions RatPak antenna switch.  The 
only thing I can figure is that there is some reactance in between the 
amp and the Mark V that is not tuned out.  Now, I don't use the tuner 
in the Mark V to tune this out - Alpha advises against using any tuner 
in front of it - but, boy, am I tempted !

73, Jamie
