Hi Werner:
With respect to your second problem, the mic high / low setting is
working on #202 with latest firmware. It is easy to demonstrate if you
set the MAIN:MIC SEL to high (rP.H in my case), set compression to
zero(0), and MIC gain to zero(0), and the METER to display the ALC. Tap
the XMIT button to key transmitter, speak into mic and increase the MIC
gain to produce an ALC indication of 4-5. Then reset the the MAIN:MIC
SEL to low (rP.L in my case). Now, without changing the MIC gain or the
compression, tap the XMIT button and speak into mic. I see no ALC
action at this time. This clearly indicates that the high / low setting
is working.

today I observed a problem with my K3 ATU.
on some bands the ATU does not find a fix.
I connected the transceiver to a 50 ohm 100 Watt dummy load.
I tried on
1850 - no fix - rattle rattle - display says: - . - with Xmit: 1.0 - 1
3700 - quick fix 1.0 - 1
5330 - no fix but when I press transmit it shows 1.2 - 1 1.0 ATU in bypass
7080 - no fix with xmit 1.0 - 1
10142 - no fix with xmit 1.4 - 1 (tuner inline - 1.0 - 1 tuner bypass)
14142 - quick fix 1.0 - 1
18068 - quick fix 1.0 - 1
21000 - quick fix 1.0 - 1
24890 - quick fix 1.0 - 1
28000 - quick fix 1.0 - 1
50750 - quick fix 1.0 - 1
second problem:
I have the impression that the switch from Mic high and low level does not
work anymore. I observed a low power output (about 40W max) with Mic
high sensitivity, and no change when I switch to low. Front and Back panel is
the same.
I hope I can get a hint where to look.
