Mike was MOST helpful to me in getting my 2-110A's on the air...great stuff!
More helpful was obtaining a service manual off E-Bay which allowed me to
fully understand the beast, and enabled retuning of the 2-2.5 mhz band to
1.8-2.0 mhz. The detailed transformer strapping info was helpful in changing
everything over from 208 to 240 volts.

I did not want to bypass the drivers on my units. I bought 30 db 300 watt
attenuators off E-Bay so that my exciter can run at 100 watts power for max.

RR! I did not want to loose any of this, so I kept my units fully "stock" and my
exciter running at a power level consistant with it's best specs. (FT-ONE)

Same here! totally awesome, no-tune, and fully remotable. I never push
mine above 1500 watts due to the relitavely small tank coils and many
door knob caps in the tank circuit. These beasts are loafing here, and
should last me a long time.
