[Elecraft] K3 Couple of issues during CQWW RTTY

[Joe K2UF]

I had the following two problems during the RTTY contest this past weekend.

 

1.-   I had to reset the mode from FSK D to AFSK A many times.  Usually when
I changed bands or a large change in frequency within the same band.  When I
get to the top of the band and want to go back to the bottom of the band I
would type the frequency in N1MM.  Radio would QSY to the new frequency but
the mode would revert back to FSK D.  This would not happen every time but
quite often.

 

2.-  Using the K3 / KPA500 setup with N1MM running on a Win XP desktop pc
with a soundMAX sound card.  The K3 running about 25 watts and the LINE IN
level set at 10 the KPA500 power out would start at about 60 to 70 watts.
Each time I would call/work someone the power out on the KPA500 would
increase.  After 8 or 10 calls/Qs the power would be up to 400 to 500 watts.
If I changed the power level on the K3 down 1 watt and then back up 1 watt
the process would start all over again.  I do not have the same problem on
CW.  I have not used the amp in a CW contest yet, but I have worked several
DXpeditions/DX stations sometimes calling for over an hour. The amp output
would stay where it was set.  

 

I have looked over the K3 manual and could not find any hints about problem
1.  Problem 2 is a real puzzler.

 

Anyone have any ideas?

 

Thanks  Joe K2UF
