Has anyone on this list used a K2 or K2/100 to drive a Drake L4-B amplifier? What does one have to watch out for and what additions/mods would be required? My main operating mode is phone. Unfortunatly due to "cavernous angioma" bleeds in the brain my former CW receiving ability is impaired so break-in operation is really not important. 73', Bob VE3XM
