Hi,
Just loaded F/W 2.72/1.98 with the "Send all firmware" option (so including
data tables). The short audio blast is still there if you are tuned to a
signal when switching on the K3. It really hurts your ears as it seems that
for this short period the AGC is not yet ON.
I recorded the 160M CW contest this weekend using the LINE OUT=phone
or speaker option. I also noticed the short burst when the radio was
turned on.
Any fixes planned for this (change boot order in DSP such that AGC assumes a
signal being present until the RX really starts to receive) ??
BTW. The updated action of LINE OUT=NOR now with outputting monitor audio
during TX is great.
Yes, this should make recording a lot easier, thanks!
I have the set the CONFIG:SUB AF to BALANCE. When looking to the monitor VU
meters on the microKEYER router software it appears that the SUB output is
lower than the MAIN output with the balance knob in the 12 o'clock position
(after equalizing both main and sub with double tapping A>B). This is effect
is also audible (~6dB difference).
What I noticed, but didn't investigate, was that there was a DC
offset in the SUB audio output. I was using Audacity to record the
audio. Using the LINE OUT to a line in on my computer. I noticed
that monitoring the sidetone showed close to a zero (if not zero) DC
offset for the left channel or the MAIN Rx. The right channel
however showed a substantial DC offset. I haven't played with the
new Beta yet, nor have I looked closely at the recording.
