A friend of mine has bought a secondhand President JFK.
The radio works perfect, but the original owner of this unit has
limited the variable output power to only 4 Watts instead of the 15
Watts, because he used an amplifier with a maximum input of 4 Watts.

How do I increase the RF output to the original 15 Watts ?

The JFK is an older model six pin mic, has no ASC and has ' deltatune '
instead of the channel 9-19 switch.

THNX !!
