Art,
3.4 Amps is higher than should be expected (unless there is a KPA100
attached). The receive current on my fully loaded (no KDSP2) is 0.44 amps
at 13 volts - this is only 0.16 amp above a typical K2 with no options. If
the normal transmit current with no options is 2.5 Amps or less, I would
expect the transmit current to increase by no more than the 0.44 amps -
still less than 3 Amps.
Normally the cause of high transmit current can be found in the Low Pass
Filter or possible with the winding of T4. A common cause is failure to
count the turns on the toroids correctly (count the turns that pass through
the center of the core - counting the outside turns can result in being one
turn off). Yes, the K2 will seem to work just fine for all other aspects.
You might ask your friend if he wound T4 for 'better efficiency at 5
watts' - if that is done, the transmit current will be reduced at 5 watts
and below, but if one tries to push it above 5 watts, the efficency
decreases (resulting in higher than normal transmit current).
