After the windstorm that broke his previous antenna, Mike is back last night with a "160m full sized vertical". I try to imagine !!
Despite poor conditions, Mike is the only one NA station crossing the pond and now take place in my 160m challenge list with 1W.
In the night Jaap (PA0O) had opened the way.

Congrats Mike and Jaap!
I've just made dedicated 20m WSPR machine.
Using AD9850 dds and its 125MHz clock is GPS disciplined.
TX final is 2SC1306 so, power is maximum 3W.
Now, I'm testing on the air.
I will test 6m WSPR beaming to south at around 10:00z.
Frits (W1FVB) gave a good example of fine tuning of window time, % time tx and pwr TX:

Thanks Frits to be on air so late for you. I hope to spot soon your 1W as Tom (G8HUH) did!
The last few days (Friday to Saturday) has seen a very bad rain storm, hitting my part of the U.K. infact our village was cut off for some hours due to flooding.. At some point during the storm the CFL died .. I think it was water ingress into the matching unit, I will carry out a post mortem when I can get the aerial down to ground level, in the mean time running I'm running a small HomeBrew active aerial at ground level RX only.
hi Jay VE3SWS-
Very good on the "real 2 way" qso mode! It was popular a few years back, but slowly faded away partially due to the long transmission sequences.. If you don't mind trading in the 5.9hz width sigs for something slightly wider- take a peek at the semi-new mode in WSJT-X ver2 called JT9-1. This popular 2 way qso mode's sigs have a width of 15.6hz, and a transmission time of 50 seconds.
WSPR 2way q's were typically found on jt65a channels, with a df around +300.
You can find JT9 sked activity on "obriensweb.com/lotw", and "Hamspots.net/jt9".
I'm open for JT9 or WSPR 2way skeds, just shoot me an email.

It was great to finally try the WSPR QSO mode in WSJT 7. Thanks to Jim, WB5WPA for the QSO - it worked out really well. It took a while to get the swing of the timing and the software, but the last few transmissions back and forth were perfectly timed and decoded wonderfully - we have the hang of it now :). It seems very boring until those 3 or 4 seconds you get to select your reply and send. You have to verify the other station heard your previous transmission, then select the appropriate response; all in the short couple of seconds after the Decode completes and a second before you start transmitting automatically at the top of the minute. I encourage more people to try this - It's still WSPR with all the wonderful SNR benefits, but can actually have a QSO similar to JT65. I wouldn't want to do it all night, but it's fun none the less. I attached a screenshot of the QSO for those who may want to look at this further. Thanks! & 73 -- Jay -- VE3SWS
Spots reported by la5zl thursday between 07z and 09z on 15m.
was actually rx'ed on 20m.
Excellent night session on 160m WSPR with great opportunities and so, great spots!!:

This morning greyline gave me 3 new NA Callsign to my 160m wspr Challenge.
I want to thanks all and hope soon same conditions to spot you with lower power!!
A warm hello to my friend George (K9PAW) still on air with 1W !! : i spoted him for the third season.
Seven European stations have taken advantage of the same opportunities so congrats to all.

Ran the CFL last night on rx test, with a very low tx ratio. This CFL is now mounted at approx. 8 meters ( 25 Feet ) above ground. It was setup up on 7.040 Mhz, where the bandwidth is much more than I expected, over 100 KHz. This little aerial is only 40cms (15 inches) in diameter. With this setup in the horizontal mode, this tiny aerial heard two Vk's and several east coast stateside stations plus various European stations. At Midnight 31st August this little setup goes on line for an extended test on 7Mhz.

This modification to GM4ISM's Excel Spreadsheet polls real time WSPRnet data and estimates the signal path quality for various communication modes: WSPR, JT65, Olivia, PSK31, CW, RTTY and SSB. These charts show expected signal dB over threshold on these modes with user-defined transmitter powers and relative antenna gains. The values below threshold are in red, above 6 dB in green and intermediate in yellow. http://www.qsl.net/kp4md/wsprmodes.htm
Note: This Microsoft Excel spreadsheet requires support for Visual Basic macros and may not work with some Excel program clones.

Tried my first ever transmission on WSPR this evening. On the very first TX period I got this:

9435km from 1W into a poorly positioned 20m off-centre fed dipole. Very pleased!
Today 24.8.13 using a Pro Am 17m band mobile whip.
I spotted this morning, with a little advance, my first North American station of my new season in 160m WSPR, as usual in my gray line:

I hope to do a great new season (27 unique NA call on the previous season) and see again all familiars of this nice band.
73 to all, Patrick, F-59706
For the last year or 2 I have played with WSPR, but never had a dedicated WSPR station. I have one set up now and will let it run for when I am home. Its tough going from a non-digital mode station to a digital mode station and makeing sure all settings are correct, as far power and audio levels. I am using an MFJ-249 radio interface card as the interface. This is a little dated, since it interfaces VIA serial port as the PTT.
Hope to hear everyone on the air!
Used the antenna analyser tonight to setup the CFL on 7.040Mhz , then just for a quick test I left it running on RX on 7Mhz.
Most surprised to hear signals from around Europe, the CFL is just 40cms in diameter and its just plonked on the shelf next to a netbook and softrock ensemble, and all at ground level. Should prove an interesting test when its mounted on the house apex at approx. 5 meters.
I found this article/ adjustment to be very helpful, I had a sideband/harmonic about 100KC high that I could not get rid of, this sample rate synchro procedure cleaned it up. Thought it would be a good idea to share with the group, in case other's are having similar prob's.
As I understand it the 30m WSPR subband ends at 10,140,100
although I know that the WSPR software includes a little bit
of overlap by default.
Unfortunately QRSS activity tends to start below 10,140,100Mhz
and there seems to be a few users using WSPR below the accepted sub band.
It may be a TX error and users not aware of it, but it would be nice
if WSPR'ers could bear in mind the QRSS activity below 10,140,100 please.
