[Elecraft] K3S Initial setup calibration problem

Hi Tom.

Ya can't always cure stupid (me of course, not you)! :-)

On waking today, it occurred to me that I had not enabled FL3 for RX and 
TX!!! Obviously I'd configured FL3 filter parameters, but totally forgot the 
rest.

I've now removed all of the config and enabling for FL1 until I install a 
filter in that position.

The first obvious thing after enabling FL3 was that even without an antenna 
connected, the receiver sprang to life and I'm quite happily listening to 
5/9+20 signals on 40 metres (with an antenna connected of course).

The 5W calibration worked like a dream and the ATU is now responding 
correctly.

I am now a happy bunny and am happy to have learned something.

Now to fit the KPA3A.......

I hope your issues are as easy to fix.

73,

Alan. G4GNX

Hi Alan,
I am also a new K3S owner/assembler. I had the same symptoms after powering
up the K3S the first time, no errors (that later resolved itself and I
received the KPA3A alert after clearing with Display button and power
cycling several times during Filter Configuration - have 2.8kHz, FM &
400hz). I have also been puzzled by not hearing any signals at this point on
any band, just the noise. However, during the troubleshooting of the
Wattmeter calibration I listened and transmitted with an old Ten Tec Omni D,
I did hear the Omni transmit on the K3S receive and visa versa while
transmitting during the K3S Wattmeter Calibration.
Get a good night's rest and we will press on later!
