I will be running my WSPR standalone beacon with less than 1W to an OCF-Dipole for at least the next 7 nights.
Already received reports from VK6XT and NH7SR so it is working ok...

My name is John and the QTH is Mount Hope in Ontario. The TX is a WSP kit buildas a club project at the PARC in Brampton. It's output power is 100mW and the antenna is a 30m dipole on a 45 degree in NNE direction.
Flex F5000 tranceiver 100W
Flex F1500 tranceiver 5W
Beam TH11DX and CL33
Despite average conditions 160m is currently attractive in EU. This morning around 38 stations on air (tx-rx).
25 dx Spots "across the pond" during greyline from K9PAW, K9YWO, VA3MW/p, VE3SWS, G8HUH, F6CNI, G3ZJG, F59706.
Congrats to John (G3ZJG) for "two-way" contacts with VE3SWS and VA3MW/P- Rarely seen at this time frame.
By my side, I hope to hear and decode Laurence (KL7L), recent WSPRer but yet very active.
One word to say "AGAIN,.."
Back in July I posted an entry to advise that the Martello Tower Group are running a WSPR beacon on 30m. We've received a lot of reports and initial indications are that it's a useful beacon to have online.
As of the 17th September we are also running WSPR on 10m using 300mW to a 5/8 vertical on top of the Martello Tower.
Hopefully this beacon will help with propagation testing on 10m and the fact that it's an 'always on' signal may persuade a few extra people to switch to 10m for a while to look for it.
As always, we look forward to reception reports and we hope that WSPR users will benefit from our 10m beacon.
At the time of writing, 10m is open from the UK to the USA with some good signals being reported.

This may, or may not, be of interest!
The antenna is a horizontal wire, about 80m long and 15 meters high, sloping down a little at the ends. The down lead of approximately 10 metres couples into a variometer matching unit and is tuned against a ground mat of 20 ground rods placed over an area of 100 m2. The estimated ground resistance is 11 ohms and the antenna radiation resistance calculated as 0.33 ohms. The overall set up has therefore an efficiency of 2.9%. My transmitter currently produces 50 watts output and therefore the erp is estimated as 1.45 watts. I round this up to 2 watts to be safe and this is what I declare in the spots.
I do intend to build another smaller transmitter to produce an erp of 0.1 to 1 watt and will run this later.
I can be contacted by email
I will be trying my 8 Band Buckmaster OCF dipole and 1 watt tonight.
Well by the end of the Month i'll be dipping my toes into digital modes, have already installed JT65, 9 and WSPR software to the laptop and my folks are getting me this for my birthday, http://www.g4zlp.co.uk/unified/DM_MiniPRO.shtml I'll be using it initially with my 857D and then my Icom 718 (once the 40m mod is done!)
I want to apologise for incorrectly posting 6 meter contacts when in fact they were 30 meter contacts.
Seems my PC and FT847 stopped talking to each other. I do not know what can be done to correct the data base.
Sorry for any inconvenience. Cheers, Dick
I will be testing my 17' Vertical at 1 Watt on 20m during the day today (9/16/2013) using Elecraft K3 and SignaLink. My location is FM18qt south of Annapolis, MD and west of Washington, DC.
I will take matching heard/hearing contacts and upload to LoTW during the week.
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.

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.

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.
