[Elecraft] K3/KPA500

[Ken K3IU]

Hi Brian:

Just want to give you a datapoint regarding your comment 
about different power output for the 2 FSK frequencies. I 
just tested my K3 (#202) using a jumper across the FSK input 
on the ACC connector and using my Diamond SX-200 power meter 
I can not see any difference in power at all on the two 
frequencies. I checked at low power (5W), mid power (60 W) 
and 100W. The needle on the meter doesn't move when I key 
the FSK input.

It is not my intent to start an argument about this, but 
just thought you might want to know my observations.

73, Ken K3IU
