Normally, when I am operating digital modes, I start out with the full
3.6 kHz bandwidth and only tighten it up when I need to. The non
standard mode is likely a much better fit for some rigs. In fact, it

Sholto, does Multipsk support 2/250? I didn't see it in the selection list.

Has anyone ever experimented with the 2 tone Olivia submodes?
How does say the 2/250 mode compare to regular RTTY?

After you came up with the idea Sholto, I was fooling around with Rtty and
Olivia 250/2, and they are very close to the same speed.
MixW has 250/2 , so was playing with it.
It would be interesting to see which would do better under poor conditions,
which are the norm lately

Has anyone tried the SkyOFDM mode or Stanag-4285/4539 modes for Amateur
communications in the SkySweeper program?
All I have is the demo which doesn't allow live contacts but it can save
and load to a wav file which could be replayed I think.
According to the SkyOFDM config there are options
Ham Radio Deluxe/Digital Master 780 would have the 250/2 as well as many
other mode as well as even 125/2. I measured the throughput of 250/2
and it appears too slow for practical use at around only 10 wpm. Not
competitive with 45 baud RTTY at 60 wpm. I am sure it would be quite
robust
John,
I am not sure which software implements the 2 tone variety other than
the Olivia Aid program?
It occurred to me after posting this that maybe the 2 tone variety of
RTTYM might be the best candidate as a comparison with RTTY.
The RTTYM mode uses a similar 5 bit character set so would be
That's an interesting frequency to select for the source of voice qrm. I
wouldn't be so fast to blame VE's or other non-US stations for this increased
interference. That is the BFO (14070 dial) frequency for virtually every

I am almost always willing to try different modes. It surprises me how
few want to do this. However, I admit that many times you try the mode
and realize that it is not going to become popular for one reason or
another.
Any new mode must have some attributes that other modes don't have and
I have been hearing more activity that appears to be illegal voice than

No...but MixW does, from the very useful to the very useless tones/BW

Good idea, Sholto;
so, do you want to try this somewhere? 30m has been good for us in the past

Sounds good. Let's coordinate via

I don't recall ever using the SSTV part of Multipsk but would be willing
to try it. 20 meters would likely be our best band between WI and FL?
Perhaps 14.074?

Does anyone have or know where I can find some windows based software for the
MFJ-1278?
Intrested mostly in rtty but other modes would be usefull as well. Don't ask me
why I want to mess with
the old thing, but guess it just because it there on the shelf. Used to have
multicom but
A quick search of this group for MFJ-1278 software may give you the
