then using the K3 in DATA A mode
this often is caused by incorrect audio levels
the k3's audio level should show 4 bars with the 5th bar flickering
I have run my K3 with the 5th bar solid and it still worked ok
the power out level is set by the K3's PWR knob
most other rigs have a different way of setting this up
doing it 'their way' on a K3 results with the varying power levels you
are seeing

Output power of my K3/100, SN 79xx, without KAT3 is very unstable in DATA A
mode. The symptom is;
1. With setting 100W output on 14MHz and 10MHz, I get 100W output for a couple
of seconds, then suddenly the output goes down to 10W or so.
2. On 7MHz and below, the output power never go up to 100W with setting 100W
output.
3. With setting around 20W output, actual output sometimes stay around 10W.
Upon holding TUNE button a couple of seconds, the output goes up to desired
level.
I guessed this might be caused by RF interfere. However, checking with dummy
road gave the same results.
These happen only in DATA A mode (I have not tried in AFSK A mode).
I got stable 100W and a little up in FSK D and PSK D as well as CW. (I have not
tried SSB yet.)
I manually made Transmitter Gain calibration without error since K3Utility
calibration capability does not work with K3 with 60m disabled for Japan use.
Any thought on this problem?
