Running 3w to ATAS-120 mobile antenna on 20m daytime.
Tried my first ever transmission on WSPR this evening. On the very first TX period I got this:
2013-08-26 18:10 G0LRD 14.097194 -24 0 JO02 1 HS0ZLG OK03gr 9435 74
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.

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.

Thank you for looking me up on here but please do go look me up on qrz.com and leave your call sign in the web button.
10.8.2013 I have started a test operation of simple homebrew DDS beacon. It currently operates on 6m only (WSPR and CW FSK 50.045 MHz) using 5W to 6 ele Yagi (heading mostly NW) from my home QTH but it is able to work on all HF bands as well (planned 80 and 17m), I will try it later. Plan is to move it to more convenient location later. Time schedule: there is a table with 10 timeslosts, each lasts 2 minutes. There are defined a mode (WSPR or CW) and freq for each slot. The timeslots are processed cyclically (that means sequence repeated every 20 minutes).
Hoping to be able to do some tests on 40 meters starting in September, running small compact aerials such as the CFL and EH etc
Costa Rica TI (tango india) is a country with a few, but dedicated,
amateur radio operators. We enjoy WSPR-PSK-CW, always learning and helping... any questions??

I enjoy experimenting with antennas and using WSPR to evaluate antennas has been an invaluable tool. I also use the SoftRock RXTX Ensemble under Linux and recently wrote some software that allows you to use the RXTX Ensemble as a VNA for reflection measurements. This has also been an invaluable tool for antenna experiments. You can find the VNA code at: http://pysdrvna.googlecode.com
I've been impressed with the mini whip antenna used at the main websdr station: http://websdr.ewi.utwente.nl:8901/ You can find out more about the mini whip at http://dl1dbc.net/SAQ/miniwhip.html Recently I had the chance to borrow a mini whip antenna and test its performance with WSPR. The results from the 30M tests were interesting:
Attic Dipole at 6M height: 820 spots, 174 farther than 4000km
MiniWhip at 3.5M height: 736 spots, 188 farther than 4000km
This was for the same ~20 hour period. The attic dipole had the most WSPR spots, but most of those were of fairly local stations. As expected from theoretical models, the dipole has better high-angle reception when compared to a vertical. The mini whip had the most distant spots. It has slightly better low angle reception compared to the dipole, again as expected from models comparing close to the ground dipoles and verticals. When you look at the actual SNR db numbers reported by WSPR, you can see local signals are clearly stronger on the attic dipole during the day. As night comes, the two antennas produce more comparable spot strengths. The fact that the mini whip actually had more distant spots was surprising and very encouraging.
Have just got my Ultimate 2 WSPR beacon running this afternoon. Currently it is lying on the table here in the shack. Power supply at the moment is 4 x 1.2v NiMH AA rechargeable cells. I am running the PA at 4.8 volts also. I fitted all the BS170 fets so the final has 3 in parallel. Measuring about 300mW into the feedline.
How's it getting out ? I have it on 80m at the moment and the first spot was from VK1KF receiving me at -20dB S/N, a short hop of 2890Km. Not using any GPS time correction yet but that will happen later this week all being well
Inviting all to sidetrack a little from WSPR my website : vk6xt.com
I can use trhge special call VI100ACT on 40m until August 7 2013. Since that call cannot be used in WSPR I will use my own call VK1WJ and all contacts mane in WSPR count also vor VI100ACT. Paper QSLs only for VI100ACT please!
