The above is news to me.  I rarely hear any digital signals on 40M much 
below 7.065.  The bulk of keyboard digital activity seems to take place 
from about 7.069-7.075 or so.  If there is a trend towards digital qsos 
down around 7020-7040 it is not discernible.  It is true that SSB from 
countries that permit it around 7070 is sometimes a problem, but I sure 
haven't noticed a "trend" towards USA ham using the digi modes moving 
down around 7020-7040.

Hi Andy,

Yes, USA ops can continue to use ~7070kHz for PSK31 and other digi
keyboarding within Lower 48 States, but it is unlikely they will work
much DX there, because ~7070 the prime part of the band for QRO SSB in
the rest of the world. The DX simply cannot hear the USA signals
there, and they don't want to work digi keyboarding there due to their
bandplans...

On the other hand, USA hams running low power will find it is very
easy to work digi keyboarding DX to Asia around 7025-7028kHz and DX to
Europe and other areas around 7030-7040+ kHz.

Re: [digitalradio] Re: New to PSK31 - advice please ??

[Brett Owen Rees VK2TMG]

Adrian,

Old computer scsi cables or cable cut off vga monitors works well and will
give you many more nicely shielded pairs than you will ever need for any
hookup. Differential SCSI cables come in lengths up to 20 feet or so. With
vga cables there is normally a bare ground wire mixed in with the various
cable outers which I ground at the PC end. I don't use an isolation
transformer and no rf problems so far.

Of course, if you have RF in your shack that will not help things. This
could happen if you are using the tuner in your rig and have a high SWR
after the radio - in which case you could have high currents on your
feedline in the shack (no doubt my technical description is bad - but I hope
you get the idea). Running coax to a tuner at the feedpoint to the shack
will help in reducing this issue.

Also, do you have your speech compressor switched off? Also, you may be
running your radio too hard at the low power setting. Does it work better if
you run it at full power but thottle back the drive?

Best of luck with it.

Re: [digitalradio] Best 40KHz for PSK & SSB QRP on 40 & 80M?

[KV9U]

Erik,

You are quite right.

Theoretically, U.S. hams can use CW across the 40 meter band (depending 
upon their license class), as well as operate Digital modes in the 
Data/RTTY subband of 7.000 to 7.125. In practice, this is probably not a 
wise thing to do. I would be hesitant to operate digital modes below 
7.025. That area is the Extra Class exclusive subband and that generally 
means CW and particularly DX CW.

The ARRL Bandplan calls for the RTTY/Data area to be from 7.080 to 7.125 
which suggests strongly that the ARRL is not keeping p with actual 
operating practices since the PSK31 watering hole starts at 7.070 most 
any time.

I personally have not operated digital modes below 7.070, other than CW, 
but then I have not been actively seeking DX contacts. ARRL does list 
the spot frequency of 7.040 for RTTY/Data DX and I am sure it would be 
OK to spread out from that frequency as needed if there was a lot of 
activity there. Here in the midwest U.S., I don't think that I have 
really heard much RTTY/Data below 7.070 though.

73,

Rick, KV9U

[digitalradio] Re: New to PSK31 - advice please ??

[Leslie Elliott]

Hi - If you want a complete soundcard interface in kit form, at a low
price, I recommend the one being sold by Dinish Gajjar, VU2FD.  I bought
one recently, and am pleased with the quality vs price.  It only costs
$18 US and I paid $5 US for air mail shipping from India to the US.  So
for $23, I got all the parts, isolation transformers, an opto isolator
for PTT, and a beautiful PC Board.  There is no step by step
instructions with it, but the schematic, parts list, board layout etc.
are all available on his website, as well as ordering information.  Here
is the link:  http://www.foxdelta.com/products/soundcard.htm
You have to provide
your own cables, but it makes it easy to configure it to your own needs.
I am capable of scratch building a interface, but at this price, I
imagine it would have cost me more to track down and purchase all the
individual parts, plus I got a nice PC board too.

Actually, I just re-read that.  They were not QSL'd , just QSOs.  I

Hi Andy,

As of 15 December 2006, the USA "data" subband defined by FCC is
7000kHz to 7125kHz. So you are fine at 7035kHz.

Throughout much of the world, including USA, the traditional operating
practice has been for 7000kHz to 7025kHz to be somewhat of an
"endangered species preserve" for morse CW. However, that certainly
isn't set in stone in USA. 

Considering USA's recent diminishment of the data subband segment on
40 meters, the projected increase in the number of Extra operators,
the declining use of morse CW in the world, and the increasing use of
digital keyboarding, the trend is heading toward more digital
keyboarding being used in USA in the 7020kHz-7040kHz part of the 40m
band, especially for DXing. This is compatible with bandplans and
actual use of digi keyboarding in the rest of the world. The newer
keyboarding modes are able to decode better than -13dB SNR, so this
makes low power DXing a reality for the average USA ham on 40 meters.
 Throughout most of the world, 7040-7100kHz is filled with QRO SSB.
The SSB QRM makes 7040-7100kHz somewhat uncompatible with low power
and weak signal digi keyboarding DXing.

Check the band chart, CW,  is allowed from 7.000MHz to 7.300MHz, the 
segment from 7.000MHz to 7.025MHz is for Extra license only, but CW, 
data and, RTTY is allowed in that segment of the 40 meter band in the US.

I think I can understand why.  Why does it have to be so complicated to

[list email filter]

I thought that 7000 - 7025 was the Extra CW / RTTY / Data segment?  At 
any rate, aren't we (USA licensed amateurs operating in ITU Region 2 or 
in international waters aboard a USA registered ship) allowed to operate 
CW anywhere we have privileges (with the exception of 60m)?  Or have I 
missed something with the recent changes?

USA

7000 - 7125 is OK for Data

7025 - 7125 is Data & CW

CW is not permitted in 7000 - 7025

Re: [digitalradio] New to PSK31 - advice please ??

[Chas Nagel]

Two things I did when I started out with BPSK31: I purchased a Donner interface 
(Web address is http://donnerstore.com,) and I purchased a PSKMETER (Web 
address http://www.ssiserver.com/info/pskmeter). Also when tuning up and 
adjusting your sound card use a dummy load and you should not have to run more 
than 40 watts, usually less. Donner makes interfaces for a number of popular 
rigs. I mention Donner's only because it's probably the simplest to hook up but 
their are many good interfaces on the market some that do quite a bit more. So 
you need to do some research. 
   
  Enjoy.

'direct' - no opto or transformer isolation. 
I can read the PSK31 quite nicely (using DigiPan) - and load up the TX
on low power (10W) - but higher TX power seems to generate odd squeaks
and general instability
...also - I have yet to get a reply from any other station on PSK -
which makes me wonder if my signal's getting distorted past the point

Does anybody have a source for 1:1 audio isolation transformers ? I
can't seem to find them from the usual suspects (ebay, CPC...?) -
would need to be an organisation that ships to Ireland.

Many thanks in advance

Re: [digitalradio] New to PSK31 - advice please ??

[Andrew O'Brien]

Adrian,

How are you connecting your PC to the radio?  It just a straight connection
of cable from/to the souncard and rig?  I did this year ago when PSk31 was
new, even with this potentially poor method I was able to get 20 watts out
without an nasty raspy signals.  20-30 watts is plenty of power for PSK31 in
Europe.

In the old days of PSK pioneering  the most common QSO task was one of
getting signal reports.  Operators were happy to spend time with a new PSKer
and let them vary their ouput levels until any distorted signals were
eliminated or greatly reduced.  If we can find a ham from this group that
can set up a schedule with you, it will help you a lot.

Aside from the isolation issue, there is also the need to make sure that
your signal is not too "hot", that your audio output from the soundcard is
low.  In Windows soundcard mixer, make sure you have the audio slider at a
fairly level.  Start low and increase it slightly.  I assume you have also
read about the need to check your ALC settings.  No ALC reading , or a very
slight hint of ALC on the meter, is usually recommended.

Sorry I can't help with a source of opto isolators in Eire.  Do they have
Dixons there or Tandy?  In the USA Tandy sells them.

[digitalradio] Re: Best 40KHz for PSK & SSB QRP on 40 & 80M?

[expeditionradio]

In our current IARU Region 3 bandplan, 
digi keyboarding is 7025kHz-7040kHz. 

SSB 7030kHz-7100kHz is totally packed with SSB voice signals here.
Often there are SSTV signals 7033 LSB and strong Siberian CW beacons
around 7035kHz-7040kHz.

In actual practice, if one goes with the bandplan, 7025kHz-7030kHz
seems to be the only spot remaining for digital keyboarding here in
this part of Asia... with 7025kHz-7027kHz the best spot. That's where
you will find most of the JA, BY, and HL digi stations also.

Just remembered to look at Andrew's proposed calling
freq. list and the new ARRL band plan list on my wall!

Do these look OK for digital & SSB modes if one is
limited to a 40KHz total range?

Note:  I want to be certain that at least part of
each segment is in the USA General Class portion
so I don't miss those ops.
