[Elecraft] K2 Problem in NAQP

[Jim Harris]

Don,

Thank you for the suggestion.  I've already done that and it looks like both are now the same.  I want to do an on air test before getting near another RTTY contest so I will have to time tweak anything before I have another panic during a contest.

I still don't understand why 15 meters was okay and 20 and 40 meters were not.  I know about the inversion of side bands at 17 meters and above.  But in my thinking the problem should have occurred there as well but on opposite side bands. 

Thank you again for your help.

 
Take pride in the USA. 73


Jim, W0EM

Connect the K2 to a dummy load, and connect a short antenna to the K3 - place the antenna close enough to the dummy load to give about an S-9 indication on the K3.  Transmit with the K2 and listen with the K3 - you will know immediately whether it works or not.

Hopefully, I can get an on air test in a day or so with a friend to confirm all is well.  In spite of my best effort I guess I goofed it up the first time.  I've been unable to find clear instructions in the assembly manual nor other instructions available on the internet on what values are correct for the BFO and DAC values.  Those values are in the assembly manual for LSB/USB and CW and it's reverse but not for RTTY.  I guess I had a one in two chance of getting it right and didn't do well on the odds.
