[Elecraft] K2 and RTTY-settings ?

[Dominik Bugmann]

Over the weekend I successfully managed my first RTTY QSO's during BARTG
RTTY Contest. As you can read on
http://www.swiss-artg.ch/hb9czf/contests/bartg03rtty/bartg03rtty.html I
experiecend some initial challenges.

I used MMTTY with standard setup (Mark 2115 Hz and Shift 170Hz)
On my K2 I enabled RTTY mode "r".

Is there a RTTY guru on the list who can answer following questions:

With help of GRAM I tried to move my filters to 2200 Hz center frequency.
- on 10 + 15m I could move the filters to 2200 Hz, on the lower bands it
would not work (the range was too small)
- then on the lower bands (20,  40, 80) I had to switch to "RTTY Rev" in
oder to move my filters to 2200 Hz.

Is this the way RTTY works on a K2 ?

Due to the fact I had to run "RTTY Rev" I also had to reverse the mode on
MMTTY.

What filter bandwidth would you recommend ? Same steps as for CW ? Over the
weekend my smallest filter was 1.6 kHz and sometimes I had inband QRM (as
expected).
