Hi David:
I've noticed something with my K2/100 and wonder whether this is normal
behaviour or not ??
When I switch to a new band and send CW using full power, I don't seem to
get full output power on the first couple of dits (or dahs), according to
the bargraph power meter. After the first couple of dits the meter reads
full scale, and continues to do so whilst I remain on that band.
I also get the same thing when the turn the power back to 10 watts.. I
only get the first 1 or 2 LEDS lit with the first couple of dits, but then
full scale on the rest.
This is normal operation. The K2 incorporates a digital (rather than
analog) ALC circuit. As such, it must sample the output power level in
order to be able to determine how much drive to apply. This takes
several output cycles to accomplish and that's why you must apply a bit of
RF in order for the ALC to find itself and do what it needs to adjust for
proper output level.
Cheers,
Tom Hammond N0SS
