K3 Audio Volume

[rfenabled]

Hi

Again today I had soft audio when I turned the K3 on.

I pressed the ATU button and the volume became loud and has remained at that level.

Here are the settings.

7.102.00 LSB
Width. 2.50
FC 0.50
Hi. 1.75
LO. 0.00
Filter 2.1 8 pole
(Others installed are also 8 pole 13,6,2.8 and 400)
Antenna is 80M full wave loop and has a 1.2:1 dip on this frequency)
AF knob was at quarter PAST the hour as the audio is generally very low and has been for a long time.

After the change in volume it sounds great at the 11 o'clock position.

FW ver 3.41

Hope this helps someone figure out what may be causing this up/down audio change.

K3/100 #679

Just a thought, but maybe it is a bad relais in the ATU?
I had once problems with higher SWR at 10m although the antenna was ok. Cycling the ATU on/off cured this problem.

What is your SWR before the ATU tuned the antenna?  Perhaps you have low volume because you're running with a 12:1 SWR?

Gary:

NEXT TIME it occurs, and BEFORE you do anything
else, find a signal and not the S-meter
reading.  THEN re-cycle whatever must be recycled
to obtain the expected audio output level and
THEN re-check the S-meter. If the signal level
has not changed, then the problem is (most
probably) in the AF section. If the signal is now
reading higher on the S-meter, then the problem is RF-related.
