Hi Guys. I guess I am lucky that I have a zip drive. It was donated to
me along with some zip disks, for helping out a friend with his computer
(he is not very "computer literate" and needs a lot of help at times).
By the time my log file gets to be over 100 Megabytes, I hope to have a
CD-R/CD-RW drive. I don't get to operate very much the last few months
anyway. But that's what happens when you are a full time College
student, and work too!

Hello all,
Here in the UK the problem from my view is PACTOR especially in the
evenings on 3580 & 7070, 14070 is nearly as bad. Several times I have been
in QSO and been clobbered by PACTOR stations(Mailboxes ??) and lost the
contact.
It has always baffled me why the powers that be advocated putting PACTOR &
PACKET working in the midst of other modes, I think they should have been
put either at the bottom or the top of each band so that they would not
interfer with other modes. (perhaps also RTTY)
I am on most evenings looking for QSO's on 3.5 or 7 but not many stations to
be heard. The same applies to Hellschrieber.

Again I will repeat what I have been saying for a long
time. PSK31 belows in the RTTY sub-band. Not in the CW
band. Thats why I use 7080. Its at the bottom of the
40 meter RTTY sub-band. PSK31 is far more kin to RTTY
than CW. I dont understand why DX stations have such a
problem with this. There are ttons of them working
RTTY there. Maybe I am overlooking something.

Subject: [psk31] MixW32 1.24
The latest release of MixW32 psk31 (and more) software deserves some
comment. I have been a big fan of both psk31sbw/wd5gnr and Logger 6.10
versons of PSK31. Up until quite recently I felt if you had the computing
horsepower that logger was the best implementation of psk31 that I have seen
and used.
With respect to MixW32 in its most recent releases:
There are tons of features that work very well that I'm not going to get
into. The purpose of this post is to sort of update my "assessment" of the
software, because of the many improvements that have been made that
actually affect how well the software works. (And also because I was pretty
critical of MixW32 when it first came on the scene.)
Over the last several incarnations, MixW32 has improved dramatically. Not
only have new features been added, but existing performance issues have been
dealt with. The software is being updated regularly.
In the most recent release(s) the logging has been improved (but it still is
not even remotely a match for logger 6.10) and many other features have been
added or improved on. A couple of highlights:
1. Clicking on the callsign enters it into the "system" for logging and
exchanging callsigns. (first appeared in Logger, congrats Bob!)
2. Packet using the sound card has been added (300 and 1200 baud).
3. Packet support for a KISS tnc has been added (I haven't tested this)
4. RTTY performance appears quite good, esp in the face of multi-path.
5. Processor loading continues to be very light.
In general, my initial observations about MixW32 are turning out to be true.
It has great potential. Its psk31 performance now seems to rival psk31sbw,
with many additional features. It looks like it is intended to support SSTV
and quite a few other modes in the future. It can currently be used as an
SSB voice keyer. The IMD measurement can be inserted as part of the signal
report. (insert macro)
Things I don't like:
1. The logging is primitive. (but improving)
2. The IMD measurement seems sluggish. (but it does work)
3. Tuning indications that work great for other modes seem to be ineffective
for packet. I could only get close with the waterfall.
In summary,
When I first registered MixW32, I was a bit disappointed with its
performance on psk31. I was impressed with its versatility and potential,
but didn't think it was "quite there yet" on psk31. I thought the interface
was "crude", somewhat clunky and unrefined. There were many features that
didn't work right or were unreliable. With the most recent releases, I have
to give credit to Nick ...at least for psk31, the software appears to have
"arrived" such that it is competitive with the best software available for
this mode. Of course, part of the value of the software is how open ended
its mode selection looks. This product could end up being "one-stop
shopping" for digital modes and a voice keyer...all making use of the sound
card.
It isn't free, but at this point, I consider it well worth its price for how
it performs on psk31 and rtty and it will only become more valuable as the
feature set continues to expand at its near exponential rate!
There was a lot of talk about this program when it first came out. I don't
think it lived up to its initial billing and perhaps has become lost in the
shuffle of wonderful improvements in psk31sbw, wd5gnr front end, and Logger
6.10. This post is basically saying that MixW32 may be worth a second look,
now that it has matured a bit.

Subject: [psk31] Bandplans for PSK31 (again)
From Peter Martinez G3PLX
In Europe, all the 80m PSK31 activity (and there is a lot) is centred
on 3580. We can't safely operate below 3580 here or we get jammed by
CW, as we do below 7035. 3580 and 7035 are the bottom edges of the
region 1 IARU bandplan.
On 21 MHz most of the activity is around 21080. Again, this is the
bottom edge of the IARU RTTY band. There is sometimes a bit of PSK31
activity around 21070 in the mediterranean area, but this doesn't get
jammed.
On 28 MHz, I have never heard any PSK31 activity on 28070 or 28080,
but I work a lot around 28120, including many contacts with South
America when the band is open (it's the only way I can practise my
Spanish). The bottom end of 28MHz is heavily polluted with CB, so it
helps to stay higher up, and I have also noticed that the CB activity
seems to be centred on odd multiples of 5 kHz, so it's a bit quieter
on multiples of 10kHz. We chose 28120 rather than 28050 (which is the
bottom edge of the IARU RTTY bandplan) after specific requests from
stations with licenses which do permit PSK31 to be used above 28100.
Please lets all stick to the same parts of the bands, especially
those bands where activity is currently low.

I have to add to Hasan's comments that the FSK31 works very very good , has
an very fast AFC and on 144 mhz ssb with the modern (slightly drifting ) TRX
(like IC-706, IC-746 with TCXO's etc) works under very marginal condnx
better then Psk31. It is an bit more sensitive and tracks much better the
drift.
I noticed that before and in our last tests yesterday-evening over an 150 km
path (deep QSB and hardly audible signals, it again proved to work better.
BTW: We tried out also the PSK-Hell mode (IZ8BLY), which came very near the
FSK31 results.
I wonder if it is possible to have an FSK 42 or 62 mode to compensate more
drift, so we can try out the 432 Mhz and higher.
Perhaps for the Lowfer's an FSK 8 or 16 mode would be nice.....
Cheerio now

Trouble is, your evening is the middle of the day here. I often don't
get on until after 10pm local time, or about 0500Z to 0700Z or later.
I'll check in the bottom of 40m this afternoon (your evening) to see if
I hear anything floating to the surface. Listen closely for my weak
sig. ;o)

I've dug the box out of storage, and reloaded the software.
Can offer 160 thru 10

And to the guy who didn't think he could work ZL on 40.....of
COURSE you can.
But you have to get up at their sunset to do it.....like 3-4 am,

As soon as I'm back on, I will post my monitoring/operating

We get a lot of QRM on the current PSK31 freqs. by CW
and those blasted unattended pactor stations
especially on 20M. Oh well. I work 40M to talk to the
mid to eastern US not DX anyway so in this case it
really shouldnt matter to europe what freq. I use. I
think most people who work below 20 meters arent
really looking for dx anyway. Especially at night.

I tried a little experiment this afternoon. I fired up and worked my
way between (CW) stations in the 7035-7040 segment. I was asked to move
by two CW stations, even though there was nothing within 500hz of me.
Attempts at jamming were just starting as I moved back up to 20m.
That's a very popular part of the band in the US for CW. It is only
10KHz above the bottom of the general CW band. Frankly, it's where I
would normally hang out on CW myself, if I wasn't down in the bottom 25.
That's going to be a hard one to make fly Stateside.

a computer interface for your rig, you can read the operating frequency

both have their uses. Another feature, the program reads the call
following the DE, and enters it into your display for you to accept if you
want to call him and gives beam pointing information to his country.
Every release has some additional features and improvements to
existing features. It's handy having several digital modes in one
package. Makes you even think about using some of them, like
HF packet. I have run numerous tests, and I can't find any difference
between the weak signal detection capability of MixW32 and
PSK31SBW except that which can be explained by having a
larger display. On the down side, I miss having a tune mode, and I
use PSK31SBW whenever I am running a transmitter test.

7040 is the QRP calling frequency in US. It is listed as 7030 in Europe.
QRP stations call on 7040 and move up or down a few kHz, There's a bit
of Pactor QRM, and some non US SSB. To add PSK31 here would be a
big mistake, although I don't believe there would be an attempt at jamming, as
5 watts doesn't jam very much. 7035.15 is just general CW and Peter has
given his reasons several times why 7035.15 was selected in Europe.
If we go to 7070, we will have the same problem as 7035.15.
