Hello Folks, I have been "On the Air" since April 1953 with QRP. This media is new for me and I hope to be able to take part of it soon.
Best wishes to you all.

QRP QSO on 6 NJ to FL today!
QRV WSPR 6M

Recently the command:

Some weeks ago I was lucky enough to get a spot from Israel for a 1mW WSPR signal. From that day I watched my WSPR reports from the United States more carefully than before. I hoped to cross the Atlantic Ocean with 1mW one day - WSPRing.
But on 2011-04-02 my 1mW WSPR sig on 20m has been spotted by Leigh, VK2KRR, in NSW.
In the local afternoon I had noticed that my 5W signal got rising SNR reports from VK2KRR. For his 10W signal he got reports from my side far above 0 dB. So I decided to reduce power to a level of 0.005W (7dBm). There were reports from down under even for this qrpp. So from 16.58 UTC I tried some 1mW runs. For my transmission at 17.10 UTC I received the following spot:

I was so enthusiastic, that I wrote some rubbish in the chatroom. I thought that it could have been longpath. But of course not in the afternoon. ;-))

By the way - my antenna is a horizontal wire loop 84m circumference, 11m above ground level, fed at the western corner. It does a great job on 40m and 20m WSPR dx.

Thanks, Leigh, VK2KRR, for that special spot and congrats to your big ears. (I saw your new antenna on your homepage)

Werner, DF6MK

My first day using this fantastic piece of software, perfect when you spend a lot of time homebrewing antennas you want to test, had good results way up north within the artic circle, accross western europe and all the way down to VK sotted by the mysterious VKFRG? who are you? as I would love to know what working conditions were used to spot my tiny signal all the way from the deep Tyne valley in Northumberland UK, please get in touch details on QRZ.

Repositioned doublet so it's a plain inverted V, as opposed to having a V in the horizontal plane as well. Oriented roughly North/South.
Transmit power is <1W from barefoot Softrock.

Hayo, DG9BEW, has created a WEB Page to view or compare WSPR Stations with a graphical
interface. The Data Source is the WSPRnet Database which is imported once a night.
The GUI is still BETA but working fine. Please give it a try under:

OK, since no one responded to the forum post, will have to put it here.

There are severe issues of interference from near by users of WSPR from JT65 users and vice versa on the 160m band. Not sure about any other bands? Ive not experienced it on others if it does happen.

I know we have reported problems from USA and Australia regarding this issue. With stations on either mode having their receptions ruined due to the alternating transmissions being to close together and putting up QRM across each others frequencies.

Solutions?

-The two modes need to be moved further appart?
-An alternating program of WSPR one week and JT65 the next week?
-We just give up WSPR altogether as being unworkable?

I have been meaning to get in here for some time now, and finally took the plunge.
Installed the program yesterday, and listened for a while on 20m, heard several beacons.

I may not be back in here as often as I'd like to, but this was a good first step.
Thanks Joe for helping create an exciting future, and everyone else for participating.

73 for now /;^)

Running 24/7 WSPR beacons receiver on 40m with minimalistic setup: SoftRock Lite 6.2 RX, PA0RDT mini-whip antenna and WSPR 2.11.
It works fine!
73!

Well after trying the FT-817 and getting nowhere with it I opted to try out my FT450AT and have it partially working.. Sadly TX'ing seems to be missing right now but maybe useful for reports to others :)

woke up early this morning, set up WSPR on 30m and - after a single TX period received 26 reports:

Yesterday, at approximately 1730L (2330 UTC) near Denver, Colorado USA, my system reported a signal from a station claiming to be in the Antarctic.

I performed a database query searching for this call sign being received elsewhere or appearing in the database as a reporter. Nada! This call sign does not appear anywhere else in the database over the previous week.

I'm suspicious because I'm not using a "REAL" antenna. My antenna is the rain gutters on my home and the transceiver is an ICOM IC-7200. Good receiver but far from stellar.

I'm looking for comments, are users into spoofing locations for fun?

I've noticed the odd WSPR signal right at the bottom of the WSPR display lately.
They indicate good signal strength and timing, but WSPR does not decode them.

I checked my WSPR setup with a counter locked to GPS and my WSPR tuning signal
appears to be within 0.5 Hz of nominal.

I then tuned my receiver down 20 Hz and was able to decode KZ8C and KI7AB.

Moral of the story: If you choose to transmit near an edge of the WSPR sub-band,
don't expect everyone to decode you.

Since October 2011, I've been running a Flex-1500 software defined radio in the WSPR frequency hopping mode coupled to a 40 meter full wave horizontal loop through a 4:1 Guanella balun with no other impedance matching. The standing wave ratio on the WARC bands was significantly over 3:1.

On 21 March 2012 I added a new LDG Z-11ProII automatic antenna tuner between the radio and the balun. Now, with the improved impedance matching, I have measured an increase of 1-2 dB transmitted power to the antenna on the WARC bands. Should I expect to see a similar improvement in receiver sensitivity?

Hello,
Name is Tom and I just installed WSPR 2.11.
I think I have it all setup correctly
I will see if I can hear and if anybody hears me.
Thanks

Rig is a FT-857d with SiganLink USB and wspr 3.0 under openSUSE 12.1
I am seeing multiple images of the same station. The signal is pretty hot in here.
Do they have a image problem with some type of SDR or it it on my end?

Hi Group

I am a homebrew type of person and completed my 30 meter WSPR on March 15, 2013. It took two days to get the thing adjusted to receive. I copied stations for
about 6 hours today and I will start on the transmitter tomorrow. I hope it will not take as long to complete the transmitter. I completed a transmitter unit last week but I
could not get it working. So, I left the transmitter and completed the receiver. I will try a new design which will not have all of the bells like the first. I really enjoy receiving
WSPR stations and will get the trasmitter on line this week

Yesterday I started receiving in WSPR again after a long pause of not being active in this mode. Unfortunately I only could be active by receiving in case of some "internal problems" with other rf-equipment nearby my wire-antenna.

Maybe I get my pappradio running again with wspr - at the moment it wouldn't receive any signal in WSPR... Must be a problem with Fiq-frequency or something with "swap i/q-channel" I think.

It's very difficult to find the cause of this but I am sure I would find it some day.
