[Elecraft] K2 and RTTY - a few questions

[Andy, KU7T]

Hi,

 

I literally worked my first RTTY QSOs ever last weekend in the WPX RTTY
contest. Was a lot of fun.  A few question come up.  I have aligned my
filters according to the well written document of Don, W3FPR at
http://www.mail-archive.com/elecraft@mailman.qth.net/msg103915.html.  And I
seemed to have done it right, because switching through the filters does not
move the signal, just tightens the roll off.

 

Question 1: My frequency is 1000Hz off compared to what DX cluster spots
show.  When I see  a spot at 14.077 it, is for at 14.078. This must have to
do with the fact that the filters centers at 1000Hz, but is there a way to
compensate somewhere for this? Would be nice to be able to use the band map
of my contest program to jump to stations I would like to work.

 

Question 2: I noticed that 15m and up, I had to put both MTTY and the K2 in
RTTY reverse.  Is this correct? I happen to remember that the switch to USB
from LSB happens on 20m. Now I am wondering if this is something special for
RTTY or not.

 

Thanks
