[RTTY] Being the fox - pileup running

[James C. Hall, MD]

Ed:

I will definitely take your advice by using my basic contest setup as you
have outlined. I don't own a DXP38 or any other hardware decoder, but the
idea of using multiple instances of 2Tone makes a lot of sense. I guess I
would set up as SO2V to get the second receiver on the screen ? With my
MicroHam MK2+, I can simply direct that audio to the open DI.

Thanks for the reply - it means a lot coming from an 'all-pro' !

The DXpeditions I'm familiar with use a standard logger, usually N1MM
Logger, with MMTTY or, lately, 2Tone.  I would stick to that basic setup.

Setting up multiple decoders will reduce the number of repeats required, but
that may not be a big enough factor to worry about.  If two decoders, I'd
use MMTTY Standard Profile and 2Tone Normal.  If 3, I'd add the DXP38
because it decodes off-frequency callers faster (or you'll pick up calls
faster as you tune through a pile-up).  Beyond 3 decoders, I'd do multiple
instances of 2Tone with Flutter, Selective, etc. settings.

If you operate split and have the sub-RX in the K3, I would use that radio
so you can have a DI window on both your TX and RX frequencies.  As you
note, the P3 will be very helpful to monitor multiple stations calling.

Call stacking will speed things up a bit, so that's very useful if you're
comfortable with it and adept at running it.  However, about 40% of the time
I use it in contests, I get silence in return, or else the guy I just sent a
report to simply sends his callsign 3-4 times again.  Outside a contest,
this percentage may rise.  The general public of casual ops may not yet be
ready for call stacking and therefore it could slow you down!

I can't imagine the W1AW/4 pile-ups will be any greater than the P49X ones
and the plan above has worked well there.

I will be W1AW/4 during the 3rd week of March running RTTY. I need a little
advice. I, like many, use N1MM with MMTTY and 2Tone for demodulation during
contests. Being the 'DX' for this one means potentially split operation,
something I do routinely to put DX in the log when I'm chasing - but not
being the DX.

On our DX club reflector, it was suggested that I consider MMVARI and use
its multi-channel RX and browser. This sounded appealing to me as I could
use my mouse and just click the QSO's into the log (using DXpedition mode).
I'm set up for FSK operation. With a waterfall type operation, I worry about
not tight enough filters to effectively copy the signal. It looks good and
I'm reading more on it such as using the Align button to get the target
signal properly tuned. I'll use either my Mark V or my K3. I do have a P3
panadapter, so that's another option to line up and click signals.

I plan on starting simplex and using stacking. If it gets too thick, I'll
run split. Stacking looked like a good idea for DX'ing until you realize
that there's a lot of jumping around on the frequencies in the split window
- probably not practical. My macro responses will be designed for speed -
probably as short as Ed W0YK's !

So, what do DXpeditioners et al do ?
