Hi Mike,
There are several types of Best :)
Best power-efficient for QRP texting: Olivia 500/16.
More QSOs on 20 meters when the band is open: PSK31.
More likely to get a message through, any time: ALE.

Hi,
If this is such a great mode, I wonder why so many call it a pactor
pest or a plague.
Maybe the answer is on this website: http://www.digipan.net/
Have a nice day.

Hi Steinar,
FWIW Pavel Jalocha's code is *very* easy to use, it took me just a couple of
hours to get it running in DM780.
It will be interesting to run a few QSO's next week - maybe even USA on 20m -
who knows?
Now back to the coding...

I'm very much a newcomer to digital modes, so please pardon this
question. I'm interested in designing a QRP rig that uses digital
modes for portable operation in the field, much like the KX-1 and ATS
do for CW. Other that PSK31, which digital modes are best suited for

Hello Patrick.
Thanks for your explanation.
Do I understand your S/N figures well?
Let's say I am using a 100 watts transceiver.
If transmitting
* MT63 à 10 bauds: - 5 dB and 100 wpm, 1000 Hz bandwidth, crest
factor 0.1
then I will be actually able to send energy equivalent only to 10
watts
All good points, Demetre,
While Pactor modes can not go as fast as the 8PSK2400 modes, I suspect
that it does compete well with those modes in real world HF conditions
when in the +5 to +20 dB S/N range. From everything I have been able to
find, none of the $5000 ALE modems can operate much
Hello Vojtech,
This problem of crest factor and linearity exist too with the Video ID (the one
you see appear on the waterfall).
If I send Contesta 16-50, due to the high number of carriers (CMT-Hell) I am
going to have a crest factor equal to 1/(square root of n) so very small, so

You are very correct that Clover II was not a very good mode,

considering the price, since it was only a bit faster than Pactor I and
perhaps similar in ability to operate in weak signals.

Thank you for the information on RFSM2400, as many of us suspected that
it would require a very good signal to work well. Once you reach a
threshold of adequate S/N, it probably works as

No computer needed. Also when you're operating QRP you need a large
number of potential stations to work. I really pitty the portable QRP
station with a budipole antenna trying to work the small handfull of
stations he might hear on an oddball digital mode. You might just as
well leave the

Andy,
Heard some digital tones around 14077 between 1845 to 1900 UTC, but
signals was not strong enough to decode. Sounded like Throb or DominoEX?

You never know who you are going to meet.
you will find a guy named VITO ALBANO palying drums. He took my

Since Pactor 3 can't be decoded with soundcard software and the SCS
decoder is relatively expensive, most hams can't decode Pactor 3
messages. Thus when QRM'd by an unattended Pactor 3 station, most
hams can't determine the offending callsign and so can't initiate an
appropriate action.
The only mode I have ever used that comes close to the feel of Clover
II, is the new ALE FAE mode. Currently, it is a non-standard form of ALE
and only available on Multipsk. But after you make the connection, you
don't have to switch back and forth. I did not have good luck with the
mode
Hi all,
I would like to add my two cents.

The reason that the Winlink2000 owners do not want busy frequency detect
is that they invented a particularly effective version of such a mode
and found that they would have extreme difficulty finding a wide enough
bandwidth to operate. The signal detection circuit would be reset to
standby
That was my daughter.

The same happens with pactor, keyboard mode (also on packet).
You type, the message accumulates in the buffer, until you press the
ENTER key, or exceed the buffer set size.

First off PACTOR 3 supports DCD control so it can listen before it

their automatic MBOS not support the DCD control, but the human
