[digitalradio] Try some JT65A

[Andy obrien]

Well, ROS 1 and 16 look like good new modes.  I think I will give up
on this mode until the FCC clarifies the legality for USA hams.  For
those having fun With ROS, don't forget much the same fun can be had
with JT65A (ROS1) or Olivia (ROS 16).

[digitalradio] ROS ability to deal with ALE QRM?

[Andy obrien]

Anyone been able to test ROS 16 with QRM present ?  It would be
interesting to use it on common ALE frequencies and see how it does
when a brief ALE sounding occurs.  The description suggests that is
should be able to cope with the brief "QRM".

Good question Alan.  It does seem quite robust but does not seem to add
anything that Olivia or some levels of Thor.  Too early to say for sure.

Re: [digitalradio] Re: USA digital bandplan chart

[Andy obrien]

Correct, it IS the FCC's plan but with the concepts of Regions 1's plan
squeezed in.  .  the suggestion is that we digital mode freaks use narrow
mode at the low end of the band  segment, leave the weak signal folks alone,
keep wider variants like Olivia and ROS16 for the upper segments, and keep
unattended modes at the upper end, where possible.

[digitalradio] Draft USA digital band plan (feedback solicited)

[Andy obrien]

OK, while the USA drifts from the suggested IARU Region 2 band plan,
here is an  "almost" compatible digital band plan,  "Compatible" with
the Region 1 and Region 2 bandplan for digital modes with a couple of
exceptions where "wide" and "narrow" digital modes are mixed . I mixed
them because the USA has less room for them.  Also one of my suggested
JT65A frequencies for WSPR and JT65A would differ from current
practice in the USA.  IF USA hams followed this suggested plan, it
would be broadly compatible with Europe's digital plan and would
provide a basis for the  addition of new modes and illustrate regions
for suggested "calling frequencies".  Surely too simple?  Feedback ?

[digitalradio] Draft digital band plan (feedback solicited)

[Andy obrien]

I took a look at the IARU Region 1 and Region 2 band plans, removed
areas where there are clear differences (30, 40 and 160, I'll work on
them later) , and produced a plan that is compatible with these two
regions (I'll look at other regions).  While doing this, and thinking
how "easy" the task was, I  realized that the USA may not actually
follow their own region's plan.  I'll look at that next. I am now
off to find the USA band plan approved by the FCC and find where is
differs.  Then, focus on where it agrees.

 However, for a start...what is wrong with this suggested plan for
digital modes?  Could we live with this if individual countries
allowed the use of the band  segments  ?

[digitalradio] ROS "bug"

[Andy obrien]

It seems that an "invalid procedure" error occurs if the the two email
addresses that appear in the @ macro for Baud 16 run together and the
ending ">" of the first one, does not get printed.  e.g.
  This is happened
at the moment every time SV8CS sends his info with a weak signal.
Perhaps it is two @ signs in the same string ?

[digitalradio] Rethinking digital mode band plans-developing a solution

[Andy obrien]

Just some thoughts, critique welcome.

If we think about HF  digital QSOs there are 5 general types.

1. Weak signal propagation "probes" that are frequent in nature and
regularly used by hams around the world (JT65A, ROS, WSPR,  SLOW CW),
Usually the exchange is a signal report, callsign, and location.  No
"Conversation"

2. Conversational digital modes that are hugely popular, very active,
and can include  brief contest exchanges or Dxpedition quick
exchanges. (RTTY, PSK31/63,).

3. Message delivery digital modes in common use, quite active, and
used at times for "emcomm" Pactor, Packet, standard ALE, Winmor,
PSK125-250,  Often fairly "wide" signals

4.  Conversational "rag0chew"  digital modes that are very robust and
used by a small group of hams during weak signal  or low power
conditions ( Olivia, Hell, Thor, MFSK16, ALE400, DominoEX, Throb.
ThrobX)

5.  Experimental "messing around" by digital mode enthusiasts, testing
all kinds of "odd" modes just to see how they work.  No more than 1000
hams  world wide.  Modes include
Olivia, Hell, Thor, MFSK16, ALE400, DominoEX, Throb. ThrobX, PAX ,
Chip, FPSK, RITTY, PSKAM, QPSK, Contestia, RTTYM, ASCII, Voice, ROS 1,
JT64, JT6M, MT63,


A persistent issue (I avoid the word "problem" because I do not think
it is) is that each of the particular interests wants to have a common
meeting place on the dial.  For some uses, it makes perfect sense  and
for others it is not really that essential.  Message delivery systems
and weak signal detection both would logically want a common place on
the dial.  Other modes can be found by twirling the dial or using
alerting system like PSKreporter or Hamspots, but sometimes you miss a
"CQ" because you happened to be down the dial a tad.

So, what "plan" , a voluntary one, could this group of 4000 hams/SWLs
, develop that would make sense and demonstrate the concepts of hams
working cooperatively on such matters.?  One that did not wait for
regulatory solutions.

It might make sense to start with what is currently working or so
"dominant" that attempts to change would be futile, right ? So,
changing PSK31 and RTTY operations is out of the question.  WSPR and
JT65A operations seem well policed by the enthusiasts of these modes.
So that would take care of items 1 and 2 above.  What about item
number 3, above ?  I'm inclined to agree that this group might work
best if allocated a small section of each band, probably in band
segments that allow unattended operations. PACTOR is an issue because
there are so many frequencies used.  In reality though, Pactor,
Winmor, PSKMAIL, ALE,  Packet, and APRS-Packet could all meet their
goals with just a TOTAL of 6 frequencies per band. 2 frequencies per
band for Pactor, one for Winmor, one for PSKmail, one for ALE digital,
and one Packet.  Six  voluntarily protected "channels" per band,
except in emergencies.

That would leave items 4 and 5, above. That's mostly the  members of
this group,  Since there are 4000 of us, 4000 collective brains should
be able to develop a band plan for a) Conversational communication and
b) experimental messing around using a mixture of wide and narrow
modes.  Ideas ?


The outcome  , in my mind, would allow a new ham to consult a chart
that looks something like..

  160   80
  75   4030
   20etc, etc.
PSK31 (general)   .xx to .xx   to .

Showing that each mode should not cause problems, is not an FCC or
IARU requirement , if by "problems"  you mean that people get upset
when it is used on "their frequency".  It IS a problem if people use
any mode without checking to see that the frequency is clear, but
other than that... staying within the allocated part of the band, is
all we are expected to do.  It makes sense to stay clear of known
sections, like the PSK31 area, JT65A areas, RTTY DX calling area,  but
ROS has as much right to be used within a ham's allocated part of the
band, as any other digital mode.  Just listen first, and use it (if
legal in your country).

I missed their rumblings, but did not know anyone was using ROS near  the
JT65A campsite,  I will be tuned to 14080 until Man U and Everton match
starts.

[Andy obrien]

My station is listening for ROS signals on 14080 USB (dial).  I am
interested in how ROS does across the Atlantic around 10-1300 UTC when
20M is usually marginal.  Hopefully I will receive some European or

Re: [digitalradio] Re: ROS, legal in USA?

[Andy obrien]

Andy, I think you are incorrect.  50% of the 89 messages , so far, are
related to the legality in the USA issue.  You are also preaching to the
choir, here.  Most of the member agree that the regulations in the USA
should  be as you suggest, and many representations have been made.

OK, now back to reading Skeleton helmet regulations for the Canadians..

[digitalradio] ROS experiments

[Andy obrien]

My "experiments"  (many receptions and 2 transmissions)  today with
ROS 1 and ROS 16 shows that it is quite an effective mode.
Congratulations Jose.   Of particular interest to me  were the several
occasions where I decoded a signal that was not visible in the
waterfall or audible to my ears.  It will interesting to see if Tony
K2MO gets a chance to put this through the Pathsim tests and compare
it to Olivia.  My "guess" is that it will be close to that of Olivia
1000/32 , perhaps within 2-3 dB.

I should also point out that I think the software is well designed and
layed out.  Over the years we have had many modes come and go.  I
suspect that in 2-3 years time, ROS will still be used.

[digitalradio] FCC Spread Spectrum

[Andy obrien]

 3. " Spread spectrum is a technique whereby the energy of the
transmitted signal is
distributed over a wide segment of spectrum.  The signal power density
can be very low and the
duration of a transmission on any frequency in the segment of the
spectrum can be but a fraction of
a second.  SS systems, therefore, can evenly share all of the spectrum
in the available frequency
segment, despite a number of stations transmitting simultaneously.
They can often share the same
spectrum unobtrusively with non-SS systems because the transmissions
may not be noticeable to a
casual listener. "

 4.   Special Temporary Authority to experiment with SS
transmissions was granted to 25
amateur stations affiliated with the Amateur Radio Research and
Development Corporation 16 years
ago.  These experiments involved on-air evaluation of different
spreading rates, frequency ranges,
and interference to stations transmitting other emission types.  On
the basis of these tests, two types
of spreading techniques -- frequency hopping and direct sequence --
were authorized by our rules.
Under our current rules, SS transmissions may be made on authorized
amateur service frequencies
above 420 MHz with transmitter powers up to 100 watts.  Since
introduction of SS in the amateur
radio service, numerous commercial applications of SS have also
evolved, including personal
communications services, remote meter reading and position locating.

Re: [digitalradio] RTTY and mode selection on radios

[Andy obrien]

FSK is RTTY but so is AFSK.  Some rigs support the use of RTTY in FSK while
others require a TNC or sound card to generate the tones.  FSK on
transceivers tends to invoke narrower filters and the frequency you are
receiving is displayed differently.  The serious RTTY guys tend to prefer
FSK.

This post from the N1MM Logger reflector illusrates some issues..  (see also

Jose, a button that hands over to the other person in the call

e.g.  k3uk de p5dx kn

K3UK would have "P5DX" " in the destination" box.  I think it would be the

[digitalradio] ROS band plan , and other modes

[Andy obrien]

Avoid 14075-76 since this is where JT65A is on 20M.  I like the idea of us
all be around  the  same place with differing modes, that way, we can hear
people calling and do not have to constantly twirl the dial.  Since most
people's waterfalls , including the one in ROS, are 3kHZ wide , and people's
rigs often use an audio range of 3 Khz, I would like to suggest that ROS
stay within 3 kHz of where everyone else is.  Avoid the PSK31, JT65A, and
usual RTTY ranges but have MFSK16, Hell, PSK63, ROS, Thor, Throbx, Olivia,
Pax, ALE400, Dominoex and MT63 all in the same area.  Close to PSK31 too,
that way we can interest PSK31ers to try the odd sounding mode.

I''d like to suggest we look at using this mode on WARC bands too

[digitalradio] ROS Modulator- Frequency-hopping spread spectrum (FHSS)

[Andy obrien]

>From 
>http://go2.wordpress.com/?id=725X1342&site=rosmodem.wordpress.com&url=http%3A%2F%2Fwww.box.net%2Fshared%2Fq4e20pgnef

"ROS uses a Spread Spectrum technique known as Frequency-hopping
spread spectrum (FHSS). In a conventional 16FSK system, the data
symbols modulates a fixed frequency carrier; but in a FH/16FSK system,
the data symbols modulates a carrier whose frequency pseudorandomly
determined. In either case, a single tone is transmitted. ROS
modulation scheme can be thought of as a two-step modulation process –
data modulation and frequency hopping modulation—even thought it can
be implemented as a single step whereby the frequency synthesizer
produces a transmission tone based on the simultaneous dictates of the
PN code and the data. At each frequency hop time a PN generator feeds
the frequency synthesizer a frequency word (a sequence of l chips)
which dictates one of 2^l symbol-set positions. The frequency hopping
bandwidth, and the minimum frequency space between consecutive hops
positions, dictate the minimum number of chips necessary in the
frequency word.
In the receiver, the received signal is first FH demodulated
(dehopped) by mixing it with the same sequence of pseudorandomly
selected fre1quency tones that was used for hopping. Then the dehopped
signal is applied to a conventional bank of M noncoherent energy
detectors to select the most likely symbol."

This raises an issue that I have faced, that the digital modes are still so
much of a minority mode, that many days we just run in to the same hams over

[digitalradio] Amazing ! Multispsk with SDR 48 Khz RS ID

[Andy obrien]

While I am not to first to test this, I am happy to have  MY first
success with Multipsk, an SDR, and RS ID.  Patrick should get a Nobel
prize for this, it will make digital mode hunting even better .


It works as advertised. Phil KA1GMN and I did a test.  I placed my
received on 18090 and Phil sent an RS ID (he was CQing) on 18100  As
you will see in http://www.obriensweb.com/phil.jpg  , the wider (48
khz wide) Multipsk  detected his RS ID , sent an audible "beep" to my
PC , and alerted me visually that an RS ID was detected up 10 kHz.
This could be very useful for bands like 20M where there is quite a
wide range of frequencies for the digital modes (14065 to 14109).

I finally did this by stealing my son's PC , just to test.  My Pentium
2.3 single core CPU would not handle the load, but my son's Pentium
single core 2.7 CPU did so, easily.  See
http://www.obriensweb.com/multipsksystem.jpg  for system info.


Thank you Patrick.  At the moment, Multipsk is the only application
that lets you feed wide I/Q data to it so that you can decode signals
wider than the normal audio bandwidth,

Re: [digitalradio] Re: WINMOR software.

[Andy obrien]

You can monitor using Winmor's "MH" list.  That way you will get  a list
callsigns heard , but you will not see any traffic passed

example
2010/01/18 17:33:31 KM4Z 44 (EM73XW)
2010/01/18 15:57:26 NC5O 70 (EM12PX)
2010/01/18 14:07:43 I3FUE 40 ()

Other than that, all you will see if the callsign, occasionally, of people
making connnect  requests.

[digitalradio] ALE and "protected frequencies" in the USA

[Andy obrien]

I have received three emails in the past 3-4 weeks suggesting that the
FCC has an application to "protect" certain HF frequencies  and
reserve for exclusive ALE use.  Two emails also suggest that people
operating on ALE frequencies have received emails asking them to NOT
use the frequencies .  Is this just "junk" information ?  Has anyone
else heard from people objecting to others using frequencies commonly
used by ALE operators. ?  Can anyone verify that the FCC is
considering an application to exclude non-ALE stations from certain
frequencies ?

[digitalradio] Formation of WARC Century Club

[Andy obrien]

Following some interest from members of the 30M Digital Group, we have
formed the WCC (WARC Century Club), based on some of the ideas from
the Straight Key Century Club .

The goal of the WCC is to promote non-contest activity on the 30,17,
and 12M WARC bands.  This virtual  club is for all modes (SSB-phone,
CW, and D igital) as permitted by license class and individual country
regulations.  The group issues WCC numbers and encourages the exchange
of numbers with other  members during a WARC band QSO.  Several awards
have been established.

Please consider joining this group.  An application for a WCC number
can be found on the WCC web page at
http://www.obriensweb.com/warc-cc.html. A mailing list has been
established at http://groups.yahoo.com/group/WARC-CC/

Re: [digitalradio] Re: SDR-Radio with DM780 20M Digital Band

[Andy obrien]

Hi Again Ed.  I did play with the 3 VFO feature of Simon's software, see
http://www.obriensweb.com/3vfo20.jpg
http://www.obriensweb.com/3vfo.jpg (17M)

It is nice to be able to 'see" the CW , digital, and phone portions, and
click back and forth to actually hear when needed.Thanks for pointing
this out.

yes, Simon and Patrick have amazing skills.  My next venture is to get more
adept at figuring out the transmit side of things , since I am using
"separates".  I have managed to protect the front end of my SDR receiver, no
overload when I transmit.  I am manually tuning the transmitting rig to the
received SDR signal, it would be nice to sync the two rigs without tapping
in to the IF stage of the transceiver. I can do that with SpectraVue but
like Simon's software and would like to sync SDR-Radio  with the TS2000.  I
suspect there are ways to do this already and I just need to explore the
possibilities.


Having fun learning...

Andy.

[digitalradio] Focus on Hamspots

[Andy obrien]

While the "digitalradio" sked page will continue, I am switching the
primary recommendation for digital mode "spotting" to Hamspots (
http://www.hamspots.net/).  Laurie VK3AMA  has provided many
innovations to this service in 2009 and plans to add even more in
2010.  The Digitalradio tab on the K3UK Sked Page will remain but will
likely continue its current role of being more a "chat" room for
people trying to test digital modes.  For alerting as to who is "QRV"
and via what mode, Hamspots is better suited, especially now that
there is some integration with PSKreporter.  While the average PSK31
enthusiasts will almost always find someone to have a QSO with, the
original Digitalradio sked page was set-up to help those wanting QSOs
on other digital modes, and to avoid the wrath of DX Cluster sysops
who wanted only "real DX"..  Over the years things have become diluted
as people use a variety of web sites to announce their presence.  It
is my opinion that the digital mode enthusiast will be better served
with a common website where all can go, and reliably catch news of who
is active, and on which band.  The Hamspots and PSkrepoter partnership
seems to be the best site.  For those married to all three, my link to
them all on one page is still available via
http://www.obriensweb.com/skedpskr4.html

Re: [digitalradio] Is there a ham in SW Minneapolis/Bloomington who can help me to go digital?

[Andy obrien]

Hopefully you will here from a local ham.  If you do not, I may be able to
help, I have some experience in setting up a digikeyey with the Icom 7000
and Icom 746 Pro, I helped a ham in my area get all set for digimodes .

I would recommend that you start with  the DX Lab suite of applications.  I
recommend this not only because they are good, but also because the author
Dave AA6YQ is very responsive to any needs,  and Joe W4TV from Microham USA
also works effectively with Dave on such matters.  . DX Lab includes
Winwabler, this will give you RTTY and PSK only, but that is about 90% of
the digital mode activity.  If you eventually want to add other more exotic
modes, adding Multipsk would be logical because it seamlessly interfaces
with the DX Lab applications.

The game plan in such matters is to first get the Digikeyer device router
installed and talking to the program within DX Lab called Commander.
Commander will need to achieve two tasks, read the frequncy from your Icom
and toggle your Icom between transmit and receive when desired.  If that is
achieved, we are pretty much done. Then , when Commander is configured
correctly  we set-up Winwarbler.  Winwarblerd decodes RTTY and PSK.  and
seamlessly interfaces with Commander.  The set-up for someone who knows what
they are doing is less than 10 minutes.  Macros are fairly simple but take a
little time to customize , same with things like color schemes, etc.  The
souncard issues are taking care of by the Digikeyer because the sounccard is
part of the Digikeyer.  The set-up key factor is to point to the correct
audio "codec"

DX Lab Suite also includes DX Keeper, great logging software.


Windows Vista may be the challenge, I have no experience with that, a tiny
bit of experience with Windows 7.

is 192 Khz at the moment.  I expect that I will move to something like
an SDR-14 in the future and have 30 Mhz capability at some point.  I
am glad I did not plonk down a hard earned  thousand bucks to find out
that the software isn't;really  'ready" yet, and that my PC's will
need a major upgrade.  So, I am happy with the learning curve at the
moment and will be better prepared when ready to move up in a serious
way.

PSK "skimmers" are essentially already within FLdigi, Multipsk,
Winwarbler, and DM780.  Broadening PSK callsign mining to four of  5
Khz segments should eventually be possible , and not very taxing.
RTTY skimming during a contest might require several 100 kHz segments,
that might be tougher than skimming the same bandwidth for CW signals.
 I suppose the serious digital mode skimmer would want to continually
keep an eye on all PSK31 and RTTY signals just like the CW enthusiasts
want all CW segments.  If there were eventually PSK31 and RTTY
skimmers, the remaining Olivia, Hell, MFSK16, and THOR signals would
be something most would happily manually watch/listen for.


Thanks for sharing your benchmarks.

Re: [digitalradio] Multipsk- CPU tests with SDR-IQ Direct active.

[Andy obrien]

Well, you can run the SDR part of Multipsk (just press SDR  I/Q Direct
button in the configuration area, then press RX/TX to return to the main
screen.  Then you will see the SDR waterfall open up.  The problem is that
without an SDR, you will only get up to khz of signal, same as the regular
waterfall.  Som other than testing CPU load, it defeats the purpose.

I am guessing you are correct about the dual versus single core.  I may try
to minimize the other items that my PC boots at start up , but they aree not
listed by the Task Manager as taking much CPU.

[digitalradio] Multipsk- CPU tests with SDR-IQ Direct active.

[Andy obrien]

Interesting data , Tony.  I am was surprised that our similar computers have
so dissimilar results.  So , I checked a few things on different PCs here at
my location.  Here are my results, The CPU demand is based on maximizing
Multipsk's tasks (SDR-Direct active, with full RS-ID on and regular
waterfall at 4 Khz) . Casual readers of this thread should note that
Multipsk under most common scenarios for ham radio,  uses much less CPU than
below.

Shack Computer (Dell Opitiplex GX260 , 2.3 Ghz CPU single core , 1 gig RAM.
Windows XP.  Multipsk  = 95-100+ % (not usable)
Home PC  (Dell Optiplex GX270 , 2.7 CPU single core , 512 RAM, WIndows XP.
Multipsk = 65%  , worked well.)
Low end Acer Latop , 3 gig RAM, Windows 7.   .  Multipsk = 75%, worked fine.

Ironic that the one PC I want to get Multipsk to work on is the one PC that
it does poorly on !  The good news is that when maximizing Multipsk on a
basic PC , with not a lot of other  things multi-tasking, Multipsk will
work.  I am especially  pleased to see it work well on the Windows 7 laptop
which only cost $247.00

So while the  desktop computers do not have identical parameters (different
system files, ect) , I am intrigued about the 30-35% less CPU demand on the
PC with only 512 RAM but .4 Ghz more processing speed .  Does .4 ghz more
speed usually make that much difference..  Your outcomes , Tony, also
intrige me about what difference I might discover if I add another gig of
RAM to my 2.3 CPU ham PC.

[digitalradio] Understanding Virtual Audio Cable ?

[Andy obrien]

I understand sound cards.  For digital modes, we need to know how to
set up audio coming in to the soud card and out of the sound card.
When there is more than one sound card in the PC, we need to know how
to set up digital mode applications for the desired sound card.  All
relatively easy (except  the odd nomenclature in Windows Sound Mixer).
 A couple of years ago , I was having coffee with a neighbour ham who
had a new Flex 100 and he was explaining that digital mode with that
radio was a challenge (back then) and that they had to use "Virtual
Audio  Cable".  I remember reading something about it, briefly, and
then forgetting about it.  There is something about the term "virtual
audio cab;le" that causes my mind to melt, I have a hard time grasping
what it does.  Probably the word "cable" that is throwing my brain
off.

The other day, I  downloaded Virtual Audio Cable. I took a quick look
, got  awfully confused, and closed the application.  I figure that
this weekend, I will open it again and finally try to figure it out.
Would I be far off if I guess that VAC essentially creates an audio IN
and OUT path similar to having a second sound card?  I am not sure
that I have any ham radio applications that require VAC, but i figure
I better finally learn what it can do.

Re: [digitalradio] SDR-Radio with DM780 20M Digital Band

[Andy obrien]

Tony, my shack PC sounds like yours.  A Dell P4, 2.3 CPU , but only 1 gig of
RAM.  Perhaps we can compare current system resource utilization for regular
Multipsk ?

Regular Multipsk in PSK31 mode with a 4,3 Khz waterfall uses 25 % of CPU.
With RS ID on , about the same 25-26%

With Panoramic decode.. CPU increases to around 30%.

Then Multipsk with Direct I/Q mode invoked  ,   CPU increases to 60%

Then RS ID in SDR /IQ direct  invoked, Multipsk uses 90% of my CPU.


The above is JUST Multipsk related, obviously other applications , like a
web browser being open, add more demand.

My daughter is away skiing this weekend, so I may "borrow" her Vista laptop
and do a comparison.  I do not know what is realistic  for Multipsk with all
its SDR receive capability and RS ID.  I don;t really understand what actual
performance increase one could expect if CPU was 3.0 Ghz rather than 2.3,
Also not sure what performance improvement going to a dual core around the
same clock speed would produce.  On my shack PC, Multipsk seems "close" , I
am guessing if I could eek out another 10%  it would run just fine.  I'm
reluctant to put more RAM in to an old machine, but I do have a compatible 1
Gig memory chip that i could pilfer from another PC and see if 2 gigs of RAM
ease demand on the CPU.  I'm guessing it would not make much difference.  I
do have plenty of HD space.


Hope you and the family are all OK,

[digitalradio] SDR-Radio with DM780 20M Digital Band

[Andy obrien]

One of the things that I wanted to accomplish with an SDR receiver,
is the ability to keep an eye on the  whole 14065 to 14115 frequency
range.  If I was down on 14074 monitoring ALE 400  traffic, I would
miss Olivia signals that popped up in the 14109 area.  I would also
miss Hell signals at 14068.  Now the SDR affords the opportunity to
keep an eye all all at once.  My venture in to SDR from a digital mode
perspective has led to a discovery that,  other than Multipsk, the
current state of the art does not support direct monitoring of wider
I/Q data.  I'm also challenged in that my PC cannot cope with the
Multipsk CPU demand when I try direct monitoring.  So, at the moment I
am visually monitoring signals with the SDR and using traditional
software methods to decode the 3-4 kHz of audio that is fed from the
SDR to applications like DM780  or Fldigi.

At this screen shot http://www.obriensweb.com/sdrdm780.jpg

you will see how it appears.  I am simply using DM780 and SDR-Radio
software together.  When I need to transmit,  I just use my TS2000
after dialing in the signal discovered by the SDR receiver.  Simon
HB9DRV will likely "integrate" these two applications later in 2010.

I did catch a Russian on RTTY this morning that I would have otherwise
missed while I was slumming it in PSK31-land..  Multisk does RS-ID
over this entire 14065-14115 portion, and DM780 is likely going to
include this ability in the future.  If people use RS-ID often enough,
it will be really "cool" to monitor 14065-14115 and get RS ID alerts.

So, just over a week playing around with the SDR receiver... I see the
potential... digital mode applications are not quite "there" yet.
When they are "there" (as in Multipsk) my PC isn't.  This $41.00 Ebay
PC may eventually get retired for a slightly improved one with better
CPU. OK, back to keeping an eye on 14065-14115.  A-ha, an SV3 calling

[digitalradio] Super narrow filter: PSK31 with HB9DRV SDR-RADIO

[Andy obrien]

Finally!  When I bought my TS-2000 a couple of years ago, I was aware
of one criticism for the digital operator  super narrow filtering
in SSB was not as easy to achieve as in other rigs.It can be done via
a radio equivalent of standing on your head , using CW to receive and
USB to transmit.  The steps to achieve that are not easy to automate,
so I have found it difficult to cope with those monster nearby PSK
signals that swamp the waterfall,  and could be eased out if I had
better  filtering in USB. So, tonight, I decided to see how that would
be addressed with my new SDR-IQ receiver and Simon Brown's preview
release of SDR-Radio .  I was very happy to be easily able to dial in
narrow filters, til my heart's content.  All at the stroke of a mouse
slider, couldn't be simpler.  Simon's software is still very early in
development , so not yet seamlessly integrated with his DM780.  Take a
look at this screen shot if you are interested,
http://www.obriensweb.com/36hz.jpg

I highlighted items of interest in a red ellipse. I used Mixw to
decode the PSK31 because SDR-Radio does not do it itself.  Yes, I
know...  Mixw displays 20M, but I was actually on 80M.

 I have yet to try this when there  is a monster signal nearby  that
needs to be nulled out , but I think the results will be good.

[digitalradio] Future of ALE and HF Link.

[Andy obrien]

I have decided that I will not be a part of HF Link,  in the formal
sense.  Many members of the Yahoo group HFlink have been helpful over
the years and Steve especially has  been of tremendous help to all.
However, I have concluded that the rigid control and moderation of
that group, have contributed to the failure of ALE to take hold as an
effective method of  amateur radio communication.  Despite years of
efforts, ALE remains perhaps the least used method of ham radio
contact management, and is regularly used by less than 75 hams
world-wide.  I know of no other amateur radio method that is dependent
solely on one group , and that one group has such prohibitive
practices that it essentially dictates terms. The copyright policy of
the HF Link group is directly contributing to a lack of openness that
is rarely seen in the amateur radio world.   PSK and digital modes
have many organizations and email lists, CW has lots of groups,
SSB-phone a zillion clubs, RACES/ARES accepts a wider choices of
systems, weak signals modes like JT65A have varying groups, but ALE on
hams bands remains centralized via HF link.   Winmor has tight control
on the software but is generally open to input and openly allows
dissent. ALE should be allowed to flourish in an "open market" where
hams take the idea and help it evolve and succeed.  Steve and Charles
Brain have made huge contributions but the warehousing of it via HF
link have reduced it to a little understood concept .  I will continue
to use ALE both PC-ALE and Multipsk . but no longer associate with HF
Link.  I have raised this matter before , and have received
constructive comments the suggest that the "control" is to prevent
"ALE bashing"  .  I think that there  is not a lot to "bash" about
ALE...it is a very effective system, However the protectionism
exhibited by HF Link has harmed ALE more than the occasional ALE
bashing would ever do.  So, the problems of  "busy detect" and
unattended operation notwithstanding, I will remain an advocate of ALE
and hope others will help it get rid of its shackles.  Heck , lets get
rid of ALE as an "emcomm " concept , it isn't really (it could be ,
one day).  ALE might be more "sellable" as a DXing method or net
control software!

Regardless of who is in Govt at the current time, there seems to be an
increase in the USA of hams who express political opinion over the air.
When I first became a ham , my mentors explained that expressing political
opinion over the air was not within the ethics of ham radio.  Alas, this
view seems to have changed over the years, at least in the USA.  Interesting

[digitalradio] PSK/ digital mode SDR software ?

[Andy obrien]

My shack PC has some resource  issues when using the only software
that I know of that has some digital mode SDR support, Multipsk.  This
is because it requires Multipsk AND a SDR software to be used in
tandem.  The TWO applications are more than my system can handle.  I
do have CW Skimmer that does NOT require an additional application,
thus it runs within my PC''s capabilities,  While I try to free up an
better computer, I wonder if there are any existing SDR applications
that DIRECTLY  support digital modes ?  Something the equivalent of CW
Skimmer for digital modes, where you just press "start" and the SDR is
activated and digital mode decoding occurs  ?

Re: [digitalradio] Re: Initial thoughts on SDR

[Andy obrien]

Thanks for  the comments, everyone.  An SDR certainly makes the experience
in the shack even better.  Steve, I do have VAC on my PC but I have not
figured out what it does yet, your comments are interesting.  AFter 24
hours, I have used my SDR-IQ with CW Skimmer ( amazing with an SDR) ,
SDR-Radio, Winrad, and SpectraVuew.  I have finally figured out Winrad and
SpectraVie, while both appear "geeky" they do work quite nicely and have
useful features.   The only thing I have not got running is Multipsk with
SDR-Radio, Multipsk with wide panadaper display PLUS SDR-Radio is too much
for my PC.  I am surprised because I would have thought a P4 with 2.3 CPU
and 1 gig of RAM would have been able to run just these two applications.
However, SDR-Radio in is "technology preview" takes about 55% of my CPU even
at the lowest display settings and least bandwidth.  I assume beta releases
will see that improve.  Multipsk in is regular use takes about 15% CPU but
increases to 30-40% when I activate the SDR features, even with just 44 kHz
display .  The two combined crawl to a halt.  So I need to play around with
my PC some more and see if I can dump any loaded background applications.  I
will also try Multipsk with Spectravue and see what happens...

[digitalradio] Initial thoughts on SDR

[Andy obrien]

I have not had an SDR even 24 hours yet, but here are some random
initial  thoughts.

3 Yrs ago I contemplated a Flex radio and talked to a neighbour who
owned  one.   He loved his,  but warned my that they were very much a
"work in progress" and not for someone who wanted  a "has to do
everything" box.  I decided to put my hard earned cash in to a TS2000
instead.

3 years later, I have an inexpensive  SDR receiver .  I have concluded
that they are still a work in progress, software is still being
refined.  Many things can't be done easily.  However 2010 seems to be
the year we can expect MAJOR improvements  like Simon's SDR-Radio.
While Simon's product is very much a work in progress, it is also a
work of art !  Other software appears "geeky" and will scare  people
away.  Simon's looks like a radio,  and will make the rookie more at
ease.

After 24 hours, almost... I think I will conclude that seeing a whole
bunch of spectrum at once is very useful  but something you will lose
interest in on average ham days, perhaps only when hunting a specific
DXpdition will actually WATCHING the PC screen be something you want
to do.

To really get a lot of joy, you will want software that will do the
"looking": for you and organize what is heard over several hundred Khz
.  Luckily this is available via CW Skimmer for the CW fanatic and via
Multipsk for the digital enthusiast.  I am not sure what you will want
for SSB/phone signals.So, in my opinion, if you get a SDR ..figure
on also owning CW Skimmer ( $75!)  and Multipsk,  Dm780 is likely to
have significant interfacing with SDRs later in 2010,,

Pleasantly, broadcast band "Dxing" and Utility  "DXing" is a joy with
an SDR.  I don't think anyone has invented the equivalent of a CW
Skimmer or RS ID-type station identification for broadcast bands, but
I suspect it could be done if someone thought more about it  (a
digital ID broadcast by the station that software would pick up  and
display on a PC screen ?  )

Interfacing SDR's with things like clusters and logging software is
not as straight forward as it might seem... still refinements needed
for this process.

Eventually, perhaps now ...already, SDR display screens will be simply
bandmaps with station  callsigns .  The gee-whiz spectrum analyzer
type display will be a background item to show off when guests arrive,
.

[digitalradio] Digital modes with an SDR ?

[Andy obrien]

My SDR receiver is due to be  delivered tomorrow.  I am looking
forward to using a wide band panadapter for receive and having my
transceiver sync'd  for ability to transmit when desired.  Since I
vacillate between CW and digital modes , I will enjoy keeping an eye
on both portions of a band at the same time.  I am also looking
forward to trying Multipsk with is SDR capabilities and RS ID
combination.  I assume there are many others with SDR transceivers or
receivers here in this group, and wonder how you are using it for
digital modes ?

[digitalradio] ARES Preparedness / No point in ALE without ARES in USA

[Andy obrien]

I'm thinking about the Haiti situation and the use of ALE stations for
emcomms.  I'm also thinking about ARES and how it handles something
like the Haiti earth quake.

  I was impressed by the turn out of ALE hams on the air in the past
couple of days , over 50 stations ready and 'alert".  I am perhaps
biased , but I think ALE is great for emergency communications.
However, I am not sure about the effective use of ALE as it stands
today.  By default , ALE in North America is connected with HF Link
and their fine efforts to deploy a "network".  Their network has
brought several innovative methods to ALE , such as "pilot stations" ,
email ,  and SMS text messages.  However, as I watch the  ALE network
efforts via the HF Link  web site, I note the solicitations to
stations that may be en route to Haiti to feel free to use  HF link
and ALE for ecomms.  As I thought more about this, I have concluded
that since  the whole emcomm system in the USA is centered around ARES
and RACES (and perhaps a few long established emergency  nets) ,   it
seems to me that ALE stations should be part of national and regional
ARES and be "called out" as part of ARES'  structure.  This would get
many more stations to be aware of ALE's effectiveness and integrate
ALE in to a system that would see its use, rather than  almost beg for
stations to use them.

My challenge to the ARES/RACES chapters that may read this message
is... are you aware that there is a world wide network of highly
capable HF systems that can be activated and called out very quickly?
 Does your  chapter have a ALE capable station that can be activated
in the event emcomm is needed to and from your area ?  Perhaps I would
go further and suggest that each ARES group should have not only at
least one ALE station , but one PSKmail capable server, one NBEMS
station, and one Winlink/Winmor station   ( I know my local county
does have at least  one of each,  but I am not sure if  my local ARES
knows that).

Finally, I would also ask did each local ARES chapter in the USA
activate or place themselves on alert when the earth quake hit?
Before someone says well ,  we are so far away and were probably not
needed, consider the HH2JR request for a phone patch yesterday.  If
Jean HH2JR had requested the delivery of info to your local ARES area,
 did  your ARES activate and assign people to check in or listen to
the nets that ARRL announced?  I'm not talking about some friendly ham
forwarding email about  international net frequencies being left
clear, I am talking about a formal alert activation by each local ARES
in the event local traffic needed to be handled.  Even in my rural
area, I received two emails asking for help in finding family in
Haiti.  Suppose their family had a Haitian ham looking to get a
message in to my  area (or yours ) ?



Just some food for thought...

Re: [digitalradio] Haiti a test for emcomms

[Andy obrien]

Yes Howard.  The HF Ale network is very active with hams standing by but I
do not see any actual use of the ALE stations, so far.  PSKmail , as I
mentioned earlier, appears tailor made for relaying traffic from/to Haiti .
from a ham to an ISP server.  Winmor/Winlink could also carry traffic from
the island and pop in into the Internet.  The question is ... will any of
these get any actual use,  or will hams on the island revert to old tested
methods...  phone nets and phone patches ?

Although it is perhaps a little early for heath and welfare traffic
related to the Haiti disaster, my Hf station is active and scanning

I did speak to one of my professional colleagues today who is Haitian.
 She indicates very difficult communication from the island.  Some of

Re: [digitalradio] Which Digi Program ??

[Andy obrien]

I will jump in on this topic.. with the TS-440.  Using the TS440, one can
use the RCA Phono jacks on the back of the TS440 labelled AFSK In and AFSK
out.Then use vox to key the rig via software like DM780 , Fldigi. or
Multipsk.  Using this method with plain audio cables results in NO isolation
between rig and computer and increases the chances of ground loops causing
distorted or noisy transmitted tones.  If you keep the transmitted power to
around 25 watts or less , you can usually get a clean signal.  You can use
home made circuits to isolate the rig-PC or buy some commercial products
usually made for car stereo systems that eliminate ground loops.

ClubLog is a GREAT facility. The best bit is that it helps you to correct

[Andy obrien]

I have arranged for clublogs.org  (http://www.clublogs.org) to add
Digitalradio as a "club" .  This means you can connect  to their web
site, registered, and then upload your log .  The upload will be an
ADIF upload.  If you need help with that part, just let me know, it is
quite easy.  You also need to add "digitalradio" as a club you belong
to.  To do that click on CLUBS and pick digitalradio from the list.
You can add other clubs that you belong to, also.Once you have
done that you will be able to participate in a variety of challenges.
One will be between members of digitalradio, and an other can be
digitalradio versus others groups/clubs.  I am particularly interested
in a 2010 challenge for "data" QSOs.  Clublogs.org will allow you to
filter your log and see QSOs and  DXCC entities worked by mode (CW,
SSB , or DATA) .  So upload your log periodically and see where you
stand versus other people and how we stand versus other clubs.  After
you upload your log and join a club, it can take some time before your

the world. Using the logs, it is possible to offer band-mode league
tables, efficient log search tools, analysis for DXpedition planning
purposes and most wanted lists for DXCC entities (including by date,
band or mode for example).

There is a great deal of information that can be mined and analysed in
a standard ADIF file. Club Log can provide empirical propagation
charts, and give back to its users the ability to find "wanted" DX
spots, identify QSLing gaps and perform other analysis of their logs
which might be hard to do with normal logging software. Through Club
Log, I also host online log search systems for significant
DXpeditions.

One of the driving principles of Club Log is to store as many QSOs as
possible, as this makes the reports and statistics more meaningful and
representative. Everything in Club Log depends upon analysing real
QSOs, and or this reason I am very grateful to everyone who
participates. If you have not joined yet, I warmly invite you to sign
up and join the action! It is completely free."

Re: [digitalradio] What's new in SSTV ?

Phil,  Easypal is a whole different world.  Makes MMSSTV appear antique.
Give it a try some time.

[digitalradio] Time for a "Digital Skimmer" ?

[Andy obrien]

I've been playing around with CW Skimmer , again.  I'm 10 days in to
my "trial".  Previously I had tried it and gave up because I was not
too impressed with the CW decoding ability compared to that of
Multipsk ..  This time I have used it a bit more and learned more
about how to use it.  In combination with the reverse beacon network
(http://www.reversebeacon.net/) , plus some useful ways to use it with
Spotcollector and an SDR ,   I'm quite impressed with what can be
done.  Now I'm thinking maybe its time to develop something like a
Digital Skimmer.   PSK Reporter, and application specific things like
PSK "Broadband decoding" in Winwarbler, or  Superbrowser in DM780,  or
 "Panoramic" modes in Multipsk , come close ...but not quite.

To have an equivalent of CW Skimmer for digital modes , we would need
the following...

Ability to detect and decode all common digital modes via RS ID
Detection over a wide frequency range  10 kHz -200 Khz, multiple bands
at same time (with an SDR panadapter).  Multipsk can do some of this
now.
Recognition of any "CQ de K3UK" type call
Placement of any  "QRL "  on waterfall or band map
Placement of any 5NN or 599 on waterfall or band map
Placement of detected  callsigns on the waterfall (some apps can do
this already) or on a band map
Mouse controlled narrowing/widening of the audio frequency range
played via PC speakers.
A web site to accept all these spots without maps (like
reversebeacons.net) that is searchable by call and band.  PSKreporter
is good but maps make it too resource dependent.  Hamspots would be
better suited.

The key would be the ability to integrate "skims"  with  one central
on line repository and the local Telnet server capability that CW
Skimmer has.

Re: [digitalradio] Re: DominoEX, PSK63F Path Simulations

[Andy obrien]

Tony,  when you have nothing to do and are perhaps bored...  can you make a
Youtube video of how you do these tests with Pathsim?  I looked at the
software and it is beyond me.
