This is a comment about the choice of 7.040 as the WSPR frequency on 40 meters. I recently posted a benign comment on the QRP list about openings in propagation based on my spots on the 30 meter band, and received a polite but negative comment from a ham who loves QRP CW on 40 meters. His negative feelings arise not from 30 meters, but from 40M. He points out that 7.040 is still a QRP calling frequency, occupied by CW ops for many years. There always was a kind of loose "truce" with the RTTY ops who also, unfortunately, claimed this same frequency for many years, and the ARRL has listed both modes on this frequency. Now, however, with the popularity of WSPR and its long transmission time, and its automatic long running nature, it is a problem for CW ops. Frankly, considering that WSPR only needs 200 Hz of bandwidth, why can't we just move the 40 meter frequency up a few KHz? The forty meter conflict is responsible for considerable ill will among QRP ops, and is unnecessary. If this has been raised before, I'm sorry. But even if it has, I hope that the power behind WSPR (Joe, are you there?) will consider a small change.
I will be qrv sunday from local sunset till next morning sunrise 18/19 Juli for some RX test on Top Band.
Will be only RXing with my ALA 1530 loop antenne, will put him in direction NW/SE.
So lets see what we can receive this night.
As a longtime user from WSJT programs for MS and EME I also tried the WSPR program after some talk with Jan PA3FXB last friday at our clubmeeting.
Saterday I RXed a whole day and night on several bands, and on sunday I also did my first TX attempt.
Was very surprised to see my signal was received at many places in EU and even in the US!!
I am using about 1 to 5 Watt out from my FT-920, as antenne I have a 1/4 wave vertical tuned for 20 meter only.
Is great fun to see it is working in combination with the internet page WSPRnet.
Well done all!!
Greetings Johan, PE9DX, JO33md.
Been running 5 watts on 10 for hours with no spots. Bumped it to 10 watts and seems N5VP heard me. Using a 10 meter Ringo at 20 feet.
Jim ... K8CXM
had rig activated whole day on 17mtrs, but only AB3IU hrd, lots of RTTY.
Now listening on a vertical antenna.
Last week was a bust. Tonight...results.

I'm exploring WSPR for the first time. This is also my first attempt at a digital mode besides morse code. I'm not clear what the maximum spottable frequency is.
I'm using my old Dell lap-top running Win98SE with an FT-817.
I intend to try 6m, 4m & 2m with WSPR. I would like to try 70cm & 23cm.
I changed from DTR to CAT for PTT and gained rig control in the bargain.
With the 756pro antenna on Auto, the antenna switch remembers the setting
for each band. Nice.
Using a dedicated sound card for both send and receive seems to make WSPR
stable under Ubuntu.
I had to download, configure, and compile the current hamlib to get the
756pro to play under WSPR. With Fedora, the list of rigs on station setup
comes up blank. Entering the rig number manually makes it happy.
Under Ubuntu, WSPR would not save and restore the 756pro selection.
I suspect entering the rig number manually would solve that.

Yesterday was a good day for 4m Wspr: Stations in Essex, Northamptonshire, Merseyside, Greater Manchester and Cumbria were spotted, or spotting, on the band. The four metre Wspr database runneth over!
I will be on air every evening whilst the radio works, usually between 5-9pm for anyone who wants to try. Generally pointing South-East towards the continent (anyone out there?) horizontally polarised. I can switch to vertical given notice.
If you want to try and you have no one to listen drop me a message and I'll happily try and spot you.
Thanks to everyone who had a go, it was fun.
A little while ago I got tired of XP wasting more than half
my office computer's memory. I coughed up $125 to upgrade
to Windows 7 64 bit premium. If there justice, the cost of
W7 should be subsidized by hardware makers. Let me count the
ways W7 forced hardware upgrades:
Video board - The current video drivers for a Nvidia 9600gt
caused the status messages for WSPR to disappear. Upgrade
Sound board - I had been using a SoundBlaster Live! with WSPR.
No support. I got a $13 board that worked for a while, sort of.
It quit working when I added isolation transformers to the radio interface.
Now I am using a $90 Xonar DX board which is reputed to have W7 drivers.
Oh, the motherboard clock does not work well W7. Loses time like an
old wind-up wristwatch. The W7 sync doesn't work well enough for WSPR.
Windows 7 protection bollixes Dimension 4.
And there are several other perfectly good devices that don't work with W7.
People bitch about Linux not supporting devices! Offhand I'd say W7 is worse.
Most bands on the Wspr map have a filter in the drop down menu. 4m is absent even though it is possible to filter results for 4m in the old database. A very few of us in the UK are trying out 4m Wspr. There are allocations in this band being made available across Europe so there might be others out there who don't realise we are trying (some would say very trying!) :) It would be much easier to get people to try if they could see the activity as per the other bands.
Thank you for reading.
Since I first joined here, I renewed my license and upgraded to Extra!
Just this week, with the help of a post on the forum, I was able to get the IC-7200 fully functioning with WSPR on Windows. The tasks are as follows:
- Go to sourceforge (link) and download HAMLIB v1.2.11
- unzip it. We need just three files.
libham-2.dll.Copy these to the wspr program directory. We want to replace the existing versions.
- Find the text file "hamlib_rig_numbers" (at least it seems to be all plain text) and add this line somewhere:
361 Icom IC-7200 0.5 Untested
The above is a direct copy paste from my own file.
- Start WSPR. See if it complains about something in the hamlib_rig_numbers file. I messed with it for some time, I couldn't see what it was unhappy about, but I eventually got it to take the new line.
- In setup, select:
-- PTT Method is CAT
I have been increasingly fascinated by the precision and accuracy available in digitally controlled VFOs, like TCXOs, and disciplined oscillators using either Rh or GPS standards. But the lowly Si570 driving my Genesis 30/20 is holding to +/- one or two Hz, and it's pretty good against WWV, once calibrated. Right now, I've set my WSPR frequency to 10.140215, and I'm WSPRing away this evening....and that's precisely where it's being reported by most listening stations. I can even tell when some rigs are off by 10 or 20 Hz! My goodness, times have changed when I can see whether another station is off by a calibration factor of a few Hz. FYI, W3HH, you are dead on as close as I can call it! WJ2V
I got a PIC-EL to use on WSPR to save using my expensive HF radio. I got it going but was frustrated by a lack of an output when its transmitting a signal (needed to key a PA) and the DDS60 drift.
I have written up my solutions at http://g4fre.com/wspr.htm.
It includes details of how to GPS lock a DDS60
I am listening on 4m WSPR again today, RX only. Using my old Yaesu Converter and home brew Vertical Dipole antenna.
Results in the evenings last week were encouraging with Spots of G6AVK, 127km, 5Watts to his Vertical only 2.5m off the ground.
HF Tx antenna unavailable.
Rx only. Equipment FRG-100 + 100ft random wire.
Current unattended automatic monitoring of 10m
I've noticed this 'sweep' on the waterfall most days during daylight hours on 4m (in the absence of Wspr signals). When I ran on a vertical omni it wasn't present, when I switched to a horizontal dipole it was faint in any direction, on the turnstile it is quite prominent. I'd have thought it a local sproggie if it were not for the fact it disappears at night - see attached image if it works.
While I have had some support in the attempt to get Wspr going on 4m I have to say there seems to be some antipathy towards the mode on there. Here's one on The Four Metre forum:
''I'm not surprised at all that there is an absence of spots in the database.
In the first instance very few operators will know that you are 4M-active.
More importantly though, why would a cw/ssb operator want to sacrifice their operating time by listening to 70.0286MHz? They will be tuning up and down the band looking out for Sp-E openings - or more likely just watching the DX Cluster for openings.
Or is it an automatic monitoring system when you're not in the shack and we'll just have to park the beam in your direction.
WSPR isn't suitable for VHF anyway, is it? Well - that's what Joe Taylor told me when I spoke to him in person about it. ''
Not exactly encouraging and I felt quite guilty for being the source of this apparent indignance. I did point out that the operators on 6M seem to be doing just fine with VHF Wspr. I thought it was all about experimentation, not sacrificing operating time, well it is for me...
It appears that DL5RBD was receiving 20-meter signals, but reporting them as 40-meter signals on 09JUN2010.
