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.
Having run for 3 weeks or so with 5-50 watts into a vertical half-wave antenna I have switched to horizontal antennas. There was some criticism of my use of vertical polarisation on the Four Metre website. I don't believe this to be a significant issue as there do not seem to be any stations working 4m Wspr anyway. I did want omni-directional coverage and a vertical is the easy method. However the turnstile is complete and up around 25 feet. I am running 10 watts and have had some signal reports from human listeners on 70.0286-USB so the signal is getting out. However, as with the vertical there does not seem to be anyone active on 4m Wspr and it's not possible to be spotted unless there's a wspr receiver on frequency. Check the old database.
I'm off work this week so I'll keep it going on 70.0286 USB during daylight hours.
I did receive some communications via email from continental stations suggesting they'd like to spot, even though they are not allowed (as yet) to transmit on 4m. Here's hoping...
... on 30 m but unfortunately there are 3 or 4 stations that send all over each other right in the middle of the freqeuncy windows at 200.
Please after setting up your WSPR program choose something under or above the default setting on 200 to be sure not be overlayed with another station. See screenshot.

I'm obtaining very good TX results on 30m with a poor balcony mounted fishing road antenna,
about 4.5m of AWG28 wire, oriented at 45 degree, feeding a 4:1 UN-UN (T200-2) transformer, followed
by a Z11 PRO2 tuner.
At firts TX shot, reached New Zeland, ZL3TY, and many US East cost stations, with a power of 5 watts.
Then Venezuela, YV4GJN.
Thanks to both for their WSPR activity.
It's good to see some more distant stations on 10m after months of just hearing locals.

These are incorrect. Perhaps I switched between bands without terminating the Wspr program. What a shame it would have been nice. Bri G0MJI
My one-watt radio wave on 17m(18MHz) band was heared in URUGUAY.
The distance from Japan to Uruguay logged is 18584Km and this is the maximum record ever since I started WSPR.
Uruguay is almost opposite side of the Globe, so I may not get longer distance in future.
Thank you CX2ABP/Rodolfo for operating WSPR.

I've been mildly interested in WSPR (and weak signal in general). Today I decided to listen on 10m - put the RX loudspeaker on the table next to my netbook running WSPR. Shortly after it decoded 4A4BEJ at 2127Km which correlated with the database.
Wow! Nothing special here RX wise, just a quarter wave vertical and IC-706. I'm going to work with WSPR more often and think about an audio interface to the transceiver. Reading the forum here shows a good community around WSPR as well.
Good WSPRing - David.
Got my WSPR station setup. Using an FT-817 running 1 watt into a sloping 30 meter dipole. Upper end of dipole is at 50 feet. The slope should favor the west. On the first transmission the farthest station to hear me was K7LG at 3014 km. SNR was -18. Eight stations heard my first transmission: W6SZ, K8CYV, SWLPMTN, K7LG, VE7THZ, W3HH, AB6OR, AC0NM.

There is a Colorado station that seems to be very potent. W5OLF is easy to communicate with.
I'm guessing W5OLF is near a mountaintop?
I have ventured off of 30 meters (default) a few times, but have not had any response from any other band yet. I will be trying this in the future. Unfortunately, I don't have easy access to run an antenna outside. I have to crack open the door, setup my buddipole and run a line out the door. It's a very temporary station.
Will continue to experiment here in Missouri.
I really like this WSPR. I'm experimenting with it right now. I was surprised to see that I had heard a Japanese station recently...since I'm here in Mid America (STL)
I will be leaving my reciever on and seeing how many reports I can upload in the next few days.
My doublet, an ATU and a borrowed TS450s, and i'm up and running. I don't have a data interface, so i've plugged in the headphones and placed them on the laptop, near the microphone. It works!! I've heard my first 10 spots. So now I can search for my callsign on the database and get some hits. Hooray.
Now, why am i getting upload timeouts? Must sort out a data interface. Must tidy the shack up so i have desk/shelf space so i can leave this kit running... must get a longer piece of paper for my to-do list....
Hi. 6m WSPR users, please have a look at this post: http://wsprnet.org/drupal/node/1807
Just having a lazy day on 10.3870Mhz and running the transmitter at 2 watts.
Antenna is my Horizontal loop of 40 Meters of copper wire.
Not doing bad so far, Heard America and Italy as ususal.
Conditions seem variable, some QSB and bad band noise but workable.
Sorry, after double checking the power out i find i am in fact running just 1/2 watt!
This should be fun.
TRX is the Kenwood 480Hx and using ALC control to turn down the wick.
I've been trying out WSPR for just a few sessions now. Even my puny little signals have been heard all the way from NA to Australia - all from my little QTH in suburban London. This really is quite addictive.
Spent the weekend shaking down one of the first production unit FLEX-1500s with WSPR. My first experience with WSPR and lots of fun! WSPR 2.0 seems to run very well with PowerSDR. 13K km @ 0.5w, 2400 km @ 50mW. Watching for 30m to open up again tonight then going to connect the transverter output +3dbm and let it run for the night. Thanks to the folks that have done all the work to let me have some fun!
I wanted to express appreciation to all who sent emails and responded to my inquiry about setup of the Yaesu FT-817 on WSPR. It's been working like a charm all week, sometimes on 40, mostly on 30M. What a hoot!
I am having so much fun seeing how far my puny signals can be heard and vice versa! I've dropped it from 5 watts at first, to 1 watt, and now run mostly 1/2 watt.
Looking forward to seeing you signals on my activity screen/map! 72 (that's the QRP version of 73!)
Based on the discussion in the forum and some offline email, I have updated the frequency list to show 144.489 as the 2m recommended frequency. Please let me know if this causes any issues for anyone.
