Yesterday I started receiving in WSPR again after a long pause of not being active in this mode. Unfortunately I only could be active by receiving in case of some "internal problems" with other rf-equipment nearby my wire-antenna.
Maybe I get my pappradio running again with wspr - at the moment it wouldn't receive any signal in WSPR... Must be a problem with Fiq-frequency or something with "swap i/q-channel" I think.
It's very difficult to find the cause of this but I am sure I would find it some day.
For those of you who do not have a Software Defined Radio and would like to monitor the incoming WSPR signals on a sprectrum analyzer, try this one, works great!!

Hi, W7FJ put up a video of my VCXO-AXE using a GymBoss as a timer:
I also want to point out that there is an accessory timing board that I developed
which I have used for over two months continuous without synchronization loss.
Anyway thanks to a user for the youtube video; thought others might be interested.
Hi all, just to let you know, a while back I created a Facebook group for 160m WSPR enthusiasts. There is a few people who have joined the group from different countries, its quite good and easy to advise of your activity and meet up with friends with similar interests.
As a bit of an experimental thing, I thought I would make some group pages for those interested in 10m WSPR and 6m WSPR, just to see how it would go and give those on Facebook an interest group that caters for them too.
It may be especially helpful on 6m to help group those interested together and may help get some longer paths achieved.
I know there has been a WSPR Group page, which covers everything, but not everyone wants posts about 30m bands etc. So I thought I'd set these up for those with specific interests.
10m WSPR Facebook group - http://www.facebook.com/groups/188699241232946/#!/groups/188699241232946/
6m WSPR Facebook group - http://www.facebook.com/groups/188699241232946/#!/groups/361822510505153/
Anyone interested is quite welcome to join. At least it will give WSPR and these bands more exposure and chance to attract other users who may come across the groups in their travels around the Facebook world. And a good way to get to know other WSPR users with similar interests.
I finished the receive portion about a week ago but for the life of me could not seem to pick up any signals. Had what seemed to be signals on scope / waterfall but nothing decoding in any software.
Last night I went out and got a set of speakers so I could hear as well as see what was going on. Tried using a headset before but can't really walk around the house with them:)
This way I could just let everything run and come to the radio if I heard something.
Anyway this morning heard my first CW on 15M. I don't know the code so not sure who or where it came from but no doubt it was a good signal. I was getting worried the radio wasn't working. Using a small but relatively powerful dual core DC powered micro computer I built. The computer and radio only pull about 60 watts max off a deep cycle battery.
Time to move on to transmitter stage:)

I built a Softrock RXTX Ensemble transceiver for 40m/30m/20m. Running it with WSPR 2.11 r226, I made my first contacts with the transceiver today, running it with a pack of rechargeable cells, wired to a Creative EMU-0204, with no PowerSDR or VAC. I will be describing my setup in a separate entry soon.
Dear, it's a 3rd day in a row I am able to hear as well as am being heard by VK0TH Travis at Macquarie island on 30m/WSPR around 21-22z. Wish we could try JT65-HF one of these days while conds last yet...

Been tinkering with Ham radio for over 30 years, got licensed in 1982. Since those days that have gone by I have tinkered with SSB,PSK31,JT65HF,HELL Modes,and recently found an interests in RTTY.
I live in the Philippines at the moment with my wife and son, and I usually spend alot of my free time operating on the bands. Last few years its been 6m as well as the others. I find the hobby to be very rewarding and more enjoyable than anything else.
I also enjoy other radio hobbies like Shortwave and Ute bands, and have been to many shortwave stations over the past 20 yrs, like KTWR,FEBC(SAIPAN)AWR guam.
Will post what I can and also on my webpage www.myradioworldandcatches.com/blog
Here I am...first time logging on the wsprnet! Glad to be here. I will be on the learning curve for a while but hope to get talking to some of you folks out there. I am only on 30m with a small j-pole antenna, so I don't know how many folks I'll be able to talk to. Best wishes to anyone reading this!
Last night I compiled, and wrote a quick how to compile WSPR 3.00 under Debian testing (wheezy) amd64 and the problems I encountered in the process.

Last week I started to transmit with my new multi-band wspr beacon. Hardware is here:
This is multi-band multi-mode beacon and now I transmit wspr and opera (http://groups.yahoo.com/group/O_P_E_R_A_/) on 10Mhz, 7Mhz and 3,5 Mhz, RF output power after filter(s) is approximately 11-14 milliwatts, input power ~ 30 mA on 12V DC battery.
Signal from propeller IC PLL is dirty and I decide to not use any amplifier.
Antennas: quarter wave vertical for 30m, quarter wave vertical for 40m, two phased verticals for 40 meters and long wire for 80m.
On 30m I received many reports from EU but noting from DX stations. On 40m with vertical max distance was north EU about 2600km but with two element I have almost every night some report from North America stations. Till now I don't receive any report on 80meters and next days will try with different antenna.
I receive only EU 30m opera reports, nothing on 40 and 80m...
73 to all,
The best amplifier is antenna :-)
I was surprised to see MY OWN call sign and decode appear in the decode window, history window, as well as corresponding signal trace on the spectrograph!
Not considering unlikely things such as reception of my own LDE (Long Delay Echo) or some other amazing effect... or someone using MY call sign, XMIT frequency and power settings, or recording my beacon and retransmitting it, what could account for this strange event? It has happened on three different occasions.
My only thought is that, if WSPR allows for full DUPLEX decoding with duplex sound card, that I may be getting some over modulation or cross talk between the input and output. BUT that does not explain how my decode is appearing AFTER my 2 minute XMISSION. (I have photo of the screen shot I can send to anyone)
I have searched WSRNnet and there does not seem to be an UPLOAD for these decodes.
I have seen info on how double decodes can happen for a rcving station, when the beacon station is over modulating- but that is not what is happening here. I am seeing and decoding a signal exactly as I am beaconing, and it is in the proper 2 minute sequence and info etc. Signal strength is -2dB...loud.
I do not think anyone would use my station info to set up their own beacon, intentionally or otherwise. Has anyone had this happen or know the cause? I had not been in the shack at that moment to "hear" speaker copy, so I can't say what is happening "real-time"
Is the mother-ship acknowledging their reception, as in the movie CONTACT?
Thank you all for the support you've given me regarding the WSPR animated GIF generator program! I've tweaked it, added a few features, fixed a glaring bug, and have released version 1.0 at this URL. Please continue to send me feedback, bugs reports, and ideas for additional features!
PS - For those of you that used it and got the dreaded 'No Spots Found' message, please try again.
From time to time WSPR's reports a decode that is just "Too good to be true".
To a newcomer they are something to get excited about. Is this WSPR mode really that amazing.
Sometimes they just "don't look or feel right" to an experienced WSPR's eye.
Sometimes they are just plain "WRONG"
If it fails the Database filters, IT thinks it is Suspect and is simply not entered in the DB.
If it passes the Database filters and is entered it may still be suspect.
Filters are not intuitive, they don't ask all the right questions and think about the Answers.
There are a few simple checks you can do, that should confirm if a Decoded Spot is Suspect.
Date and Time are rarely suspect, unless you know you were not on air at that time.
Look at the Callsign, Is it a Normal Format (prefix, number, suffix), recognise the prefix?
No, a quick check with QRZ.com or a similar DX Call book Listing.
"The search for 6p7frs produced no results!, MMM, 6p7frs looks like a callsign from Pakistan".
Not a good result, Suspect ?
Look at the Band/Distance, 50MHz, 5123kM, a Long way to go on a quite band, 1600kM is my best DX today. Not a good result Suspect?
Look at the S/N ratio -29dB, thats right at the decoders limits. We know WSPR was working very hard trying to decode something, ALL_WSPR.txt confirms the 6p7frs data looped through the error correction system 16,018 times to produce this Decode. Not a real good sign!
Look at the Grid Square BG24 the WSPR Map tells me in the middle of Antartica, Only 4 digits, A Pakistani in Antartica far from all known bases. Not an expected result Suspect?
Look at the Power, 501 Watts, Odd figures, Wattmeter that accurate?, Not really QRP,
(10 Watts or Less). Again Not a good looking result Suspect?
So our Suspect Spot Below Failed on most of the Simple Tests and I Believe it should be consigned to the Bit Bucket where it obviously belongs.

Well, I joined WSPRnet and made an account some time ago but just finally started actually using WSPR now that I have decent HF radio.
I now have a Yaesu FT-450 and am amazed at how far a low watt signal will travel in wspr.
I am really enjoying this mode and seeing so many stations active around the world.
Remember, it's a beta, and for now there's only data for December 1, 2011 thru 23:58 on the previous UTC day (assuming my auto upload scripts work!). Please enjoy!
Some of the features:
1) Search By receiving callsign (Who did I hear?)
2) Search By Transmitting station (Who heard me?)
3) User-defined spot aggregation time
4) User-defined delay between frames
5) Choice of 2- or 4-character gridsquare blocks
6) Option to draw and label grid boxes
7) Option to suppress frames with no spots
8) search limits by start/stop time
9) use transparency to make files smaller
Already Planned Features
1) Add search limits for bands(s), distance, power, etc
2) Customize legend to only show bands heard
Since I started WSPRing 3 years 38 weeks ago on 30M, I have heard data signals above the Wspr slot. Of course you actually listen to the audio when starting Wspr.
Just this morning I heard a JT65 signal inside the Wspr passband, starting up WSJT I monitored the JT65.
It was a C91 station sending a CQ, also on the WSJT waterfall was my old data signals.
Looking at the screen capture it looks like a narrow FSK signal from one station to another, one strong (S9) and the other weaker signal in return, then stops.
The signals have been on the same frequency never changing, possibly a comms link, for what purpose I haven't got a clue.
Have you heard them?
Does anyone know what it is for please post a reply.
If any 160m WSPR enthusiasts are interested, I've recently opened a "160m WSPR" Facebook page.
Just myself and Derek VK6DZ on there at present, but others from around the world most welcome and let us know what your up to in the world of 160m WSPR.
