Manager - VK5LA
Andy Williss (VK5LA) Welcome to the Survey Page.

The goal is to help us all gain a
better understanding of the ham
community... what we like... what
we don't like... about various
aspects of our hobby. Let's make
it fun and maybe kick up a little
dust once in a while. I hope you
all will participate and enjoy the
questions.

Please enter your ideas for future
survey questions yourself (click on
the "Enter your idea" link just
above) or send them directly to me
at surveymaster@eham.net .

I often get comments that there is
a commercial interest in the survey
questions and that some of the
questions are "rigged"...I assure
all eham users that the questions
are
in no way influenced by any
company, person or persons.
The questions in the survey all
come via contributions to eham or
are just plain made-up by your
humble survey manager.


Please note that there are many
potential surveys in our queue, and
many of them are duplicates.
Sometimes we combine several
questions into one. We at eham.net
make every effort to present all
content in a way that will be
easily understandable and useful to
an international audience.

Have you tried K1JT's WSPR (Whisper) mode software yet? http://physics.princeton.edu/ pulsar/K1JT/ 1JT/

Survey Comments
WSPR
Yes fascinating to use WSPR, observing propagation changes on different bands throughout the day, the effects of your antenna changes and really just seeing how far away those few milliwatts of RF can be heard.
Many thanks to Joe and everyone else involved,
Try it!!

I find it very interesting & educational to experiment with extremely narrow-band modes that operate below the normal noise-floor of voice or even CW communications.

Advancement of the radio art. Gotta love it!

Posted by N0NCO on November 25, 2012

Psssst, listen close I'm whispering
After another long work day I needed a laugh. Thanks !
After reading how well this "WSPR" mode works I may
jump on the band wagon so as to get MY toaster on the
same page as MY coffee pot to finally enjoy dark toast
and strong coffee reliably !!

WSPR
I enjoy WSPR operations on 20m with 200mw using my SoftRock SDR. Very neat way to appreciate what can be done with VERY low QRP power and a dipole! Once I saw what could be done with 200mw, 1watt seemed like pointless cheating :>)

OK...now I get what you're talking about. (A bit
slow here lately)

Yeah...I saw the D-Star thing...reminds me of a
few years ago there was a ham that had posted
on QRZ about the CQ100 net that he had started.
It was pretty amusing....CQ Skype.

Happy Holidays, anyway.

Appliances in QSO
My fridge got a qsl from the stove!

Good Gawd, what's next?

Posted by AA1BN on November 13, 2011

You are missing my point
John, What I am kvetching about is an operator coming home from a day of, let's say, water skiing, looking at the screen of his WSPR program and patting himself on the back for the "contacts" he made.

A lot like the extra points for "foreign" contacts being awarded in the D-STAR QSO party.

Legends in their own minds.

Posted by KG4RUL on November 12, 2011

WSPR as a Mode
You know, Dennis..."WSPR" is more than just the
automated propagation tool. Of course, you KNOW
that, right? I've MADE QSOs in almost every mode
contained in the WSJT suite, WSPR included, version 7
and newer. Sure it isn't "Name here is Dennis...blah
blah blah", but it's still a QSO. And hey...it's NOT
UNLIKE a QSO made during a VHF contest (using a grid
square). So, keep stating your opinion. Please. I'm
having too much fun now.

Posted by KB2HSH on November 9, 2011

Yes, I use macros
"No human intervention? Are you for real?

You mean to tell me that you DON'T use ONE SINGLE
MACRO button in any of the mode's suites you
mentioned? Be honest now. Using JT65 is like having a
macro QSO. Sure, it's push button...but with the ability
to be copied at much lower signal levels.

How about it, OM...do ya' use macros?

Posted by KB2HSH on November 5, 2011"

Yes John, I use macros for my digital programs and my word processor and my spreadsheets. They are useful tools. Now, back to the reality that a WSPR contact can be accomplished without ANY human intervention whatsoever! So, I have to believe that when you are claiming a WSPR DX contact, you are really claiming it for your computer? WOW! A DXCC totally by automation. You don't even have to be anywhere near your radio.

Posted by KG4RUL on November 9, 2011

A Few QSL Cards!
WSPR does not make "contacts" in any sense that I would agree with. No information is sent other than your call and location. The RF path is one way. The internet handles the rest.

That said, I have received several QSL cards from overseas.

What WSPR provides is a giant distributed antenna range, and you don't have to send helpers out into the rain to man it.

Many times I fire up WSPR to see what bands are open to where. I typically set power to 5 watts, sometimes less and infrequently the whole decigallon. I have hit the east coast on one milliwatt.

appliance vs. technology
WSPR is advertised/marketed/described first and foremost as a software - the only technical description of the protocol I could find easily on the WSPR page, and a pretty superficial one at that, is hidden in an appendix of the software user manual. it seems the detailed technical specifications need to be second-guessed from analyzing the source code of the software.

Amateur radio to me is a technical hobby, and I would like to understand what I'm doing rather than just using a piece of provided software - a software appliance. If I don't feel I could, at least in principle, design my own (crude) implementation, this defeats the purpose. Maybe the "code is the documentation" approach is possible, but I'd rather spend my limited time creating something of my own than reverse engineering someone else's software.

Posted by KC2KCF on November 1, 2011

Yes REALLY John!!
"You know, I almost expected there to be inane
comments from some others. But in your OWN

wouldn't THAT be considered software making a QSO?

Posted by KB2HSH on October 18, 2011"

I am referring to a piece of software handling the whole QSO without ANY human intervention - NOT PSK which requires a human to control the software. And I also enjoy Hellschreiber, THROB, MT63, RTTY, SSTV and other modes ALL with human intervention.

WSPR & JT65 LINK
Well I have never heard of this so I tried to go to the link provided and it did not load, 4 times I tried. So I tried the link in 1 of the reviews and nothing again. So I will try this someday if they ever provide the correct WEB Address.
73 everyone.

Posted by N0YG on October 31, 2011

JT65 and WSPR
My comment is don't knock it till you have tried it. New technology can be amazing and lots of fun... Never stop learning!

?
Do you actually talk and/or COMMUNICATE with the person
at the other end...? Or are you merely an extension of your
computer, i.e. the "hardware" needed to run the "software"...?

If it's the latter, then, "YUCH!!!" is all I can say. One can only
hope the novelty of this latest fad might fade into oblivion,
or some obscure niche of Amateur radio.

WSPR
WSPR is an amazing tool. With just a couple of watts reports from across the planet are possible on many HF bands with simple antennas. It was a real boon when working on 500kHz and 136kHz as the reports via the internet database allowed me to optimise my equipment and antennas. It is not a communications mode, more of a beaconing mode. A truly great piece of software, and free.

Posted by G3XBM on October 24, 2011

I run WSPR on 1 radio @.5w all the time just to check probigation around the world you don't have QSO's on it. I run JT65HF @ 5w for my QRP DXCC.

Just starting to really pickup on 160m JT65HF should be quite a few there this winter for DX contacts will work a lot better than CW at -30 db

WSPR
First I've never heard of it, second I refuse to connect my "Hamming" to a computer. I prefer to do it the old fashioned way. The most modern thing I tried was the AR9800 Digital Voice for two years. It was a bitter disappointment.

Posted by N4VNV on October 22, 2011

WSPR is amazing!
Ran this off and on last winter, and the results were amazing! Often ran with 1 watt out,and had reception on 80 M in Japan. 1 watt on 30 was heard in VK6 LP on 30! It is fun to switch antennas to see if one is better than another, which I did with my 30 M vertical and a 50' high 30 M inverted Vee. Usually, the Vee was better, but not always. Fascinating to witness the vagaries of propagation.

Posted by K8CXM on October 21, 2011

WSPR anf JT-65HF
Both of these modes are interesting. I've
spent a bit of time playing with JT-65HF. Was
running 2 watts to a piece of wire in a tree,
but now I have an actual antenna I can use.
It will be interesting to see what I can work
this way. I got lots of reports from Europe
with the QRP/Crummy Antenna setup.

WSPR is nice for when I want to play radio
but not have to do much. I can turn on WSPR
while I go about my other work.

Clock synchronization
The problem with WSPR is the need to have
synchronizsd clocks at both ends of the digital
conversation. That pretty-much killed it for
me. I think the timing issue makes the thing a
PITA. On the other hand, YMMV. And I may just
be a grouchy old curmudgeon. :-)

Posted by VK2DMH on October 19, 2011

WSPR = "Weak Signal Propagation Reporting", developed by K1JT. Google K1JT to learn more about weak signal software.

Posted by KV1E on October 19, 2011

WSPR & JT65
I use both since several months! and it's amazing. From north of France with a simple vertical i'm heard in VK wtih 5 watts or less a 16000kms DX!!!
With JT 65HF, a low power of 30W is oK to contact South Africa or Japan.No need hot vitamins! Numeric modes= The other voice on air... and a good practice to survey propagation.

Posted by F1HKN on October 19, 2011

A WSPPR...what?
What ever happened to just calling CQ?

Posted by KG4CLD on October 19, 2011

If you CAN'T hear them you CAN work them !
Other than WSPR,I don't know of another amateur
mode capable of detecting signals as low as -33dBm.
WSPR is a fantastic propagation analysis tool. I use it
to quickly find out where my 5W signal is being heard
and how it compares with other WSPR stations in my
region. The analytics reported automatically to
WSPRnet.org are fantastic. The latest version can even
frequency hop when connected to your transceiver's
CAT interface. Newcomers should keep in mind that
WSPR is not a "2-way" mode and contacts cannot be
counted towards DXCC or any other award.

REALLY DENNIS?
You know, I almost expected there to be inane
comments from some others. But in your OWN
profile...you mention that you enjoy PSK. Well, RUL,
wouldn't THAT be considered software making a QSO?

Posted by KB2HSH on October 18, 2011

As Exciting as Watching Paint Dry
The subject line tells it all. And hearing brags about a "contact" made automatically by a piece of software????

Posted by KG4RUL on October 18, 2011

Two Different Modes
Don't confuse WSPR (MEPT_JT) with JT65A.
They are different entities altogether. While you
can make QSOs with MEPT mode, JT65a(b and
c as well) is the commonly used mode.
Amazingly, "WSPR" allows captures of signals
as weak as -33 dB. Pretty incredible stuff.

WSPR/JT-65
The most commonly used implementation on HF is the JT65-HF software which is available at
http://iz4czl.ucoz.com/index/0-28

Give it a try--you'll be amazed at the performance. Most users routinely run less than 10 watts. Now that 10 meters is open, there's quite a bit of activity on that band.

Not for the ragchewer, though--short (about 4 minute) formatted exchange.
