[Elecraft] K-3: RTTY Dual Passband Question

[Claude Du Berger]

Hello Dick.
Some will prefer to use Dual-PB all the time, in RUN-CQ
and some in S&P. It's a choice.

I am new with the K3 but found a little difficult to tune rapidly
a station in S&P using the DPB. It is so sharp. Maybe with 
practice it would be ok.
So I decided to use it only when I was inf RUN-CQ mode with the
DSP filter at 300Hz. I had the clarifier ON if need and resetted
via my CQ macro. 

In RTTY my SHIFT is always centered.
If you had problems with off-freq. it probably came from
using AFC and NET on MMTTY. Here I have them OFF all the time.

I will be still experimenting that in the BARTG contest.
One thing for sure, I could feel the improment using a K3 in RTTY.

  Question: If you don't normally use Dual Passband while in RTTY Mode,  then 
  is it true that you need to be careful where the "SHIFT"  control is set?  
  I am new to RTTY and in last weekends NA-RTTY Test I  was NOT using Dual 
  Passband, and I was often off-frequency when  changing bands as my SHIFT 
  setting was often different for each  band.  I believe if I had been using "Dual 
  Passband" that I would  have been on frequency as that disables the SHIFT 
  control.  Question:  if your not using DUAL PASSBAND then what is the proper 
  setting for SHIFT?   Perhaps centering the SHIFT in the middle of the K-3's on 
  screen display?
  Or is it true that if NET is On in MMTTY then it will put the  transmitter 
  on the receiver frequency even if SHIFT is not centered?
   
  Thanks for your thoughts!

  Normally I dont need the DPB. But when in RUN-CQ mode with QRM in the  last 
  NAQP I was very happy to have it.
