Back on 20

I moved back to 20 meters running .17 watts as best as I can measure

N4EKV QRV on WSPR!

Yaesu FT-817 running 2W into a ZeroFive 50ft vertical which is fence-mounted with a few additional buried radials. Had RX working last two nights. Tonight I dusted off my old RigBlaster, reconfigured it for the FT-817, and bingo! Spotted by a VK7 on 40m in the first few hours of operation.

6 meters

trying 6 meters for a while, beam now at 300 deg running 3.5 watts

First time using WSPR last night

I made the splash last night to try out WSPR for the first time. I had been fighting with the website to actually get a working password in addition to proxy problems related to internet explorer that kept me from communicating with the server. Who knew that Internet explorer's proxy settings were different from the Firefox proxy settings... I didn't (for those of you that are as slow as I am, I use Firefox and hadn't opened IE ever on this machine).

Being a low band guy, I started out on 160. I was heard by a few stations in CA and in between but activity was generally kinda slow. I already knew that aurora activity was going to make any real worthwhile test a bit of an impossibility. Furthermore I am going to have to figure out how best to deal with automating my RX antenna selection process or at least come up with a protocol, perhaps listening to EU through their sunrise and then switching around to JA or VK/ZL. Fortunately the F/S is poor enough that I can probably avoid missing signals to the NW of me.

I switched down to 80m and there were plenty of signals so I fired up around 40 dbm and was heard by a number of station in the northeast in addition to G0 and EA4. Even with all the noise from listening vertical, I was hearing most of those reporting me, including the Europeans. I was excited to find that VK4 had been hearing me on his sunrise, about 3800 miles from my antipode.

I am currently sourcing parts to modify my RX antenna switching logic as well as changing how I de-tune my TX antenna on receive to avoid noise coupling into the RX antennas and hope to have all of that working in a couple of days. Until this is worked out, I apologize if I don't hear some of you. I am spoiled by the RX antennas and live in a noisy location just south of Dallas, Texas so some things just cannot be helped.

I hope to be back on the air tonight about an hour before Sunset on 80m and look forward to running this evening!

MAP QUESTION

MY MAP FUNCTION DOES NOT SEEM TO WORK. ANY SUGGESTIONS?

BEN, KR6E

First impressions

Running WSPR 2.0_r1714 on Windows XP Pro SP3 and a Ten-Tec Omni VII (588).

Since the O7 has an octopus breakout cable which brings audio line in and out to phono plugs, all I had to do was hook up to my PC's sound card line in and out connections and I was ready to go.

Although the WSPR application doesn't have a rig selection for the O7, the Jupiter config worked fine for changing frequencies, and VOX works for transmit control.

I notice that when WSPR is first fired up, the rig is NOT automatically set to the frequency for the selected band. Changing to some other band and then back to the desired band will then select the correct frequency.

I spent a while trying to get XMIT levels working right. At first, I simply cranked the XMIT power all the way down to 5 watts, but had a hard time adjusting the rig's line level input and the PC's line level output to a point just below ALC activation. I finally found that running the rig at full power (100 watts), but with a lower audio level gave me a less touchy range of settings that allowed me to get 5 watts out as indicated by the rig's own internal watt meter (assuming that it's correct). Another advantage to setting the rig's power this way is that the internal antenna tuner still works; when the transmit power is set below about 15 watts, the tuner won't activate when the TUNE button is pushed.

I spent a few hours playing with the program for the first afternoon, and was pleasantly surprised by how many people I was hearing and how many people were hearing me.

The big surprise was that I appear to be something of an alligator on 40m and 30m, where I'm heard by lots more people than I can hear myself. This runs counter to my real-world experience of not being able to work the folks I hear, especially on 30m.

I really expected better results when I left WSPR running in receive-only mode overnight on 40m. Reports from only two European and one Australian, with the rest confined to North America.

big signal on10.

hello and hope to sqo with you soon.more to come.k2csx mark.

Welcome new WSPRers!

I just wanted to welcome all the new users of WSPR and this site. We have had a flood of new users as a result of the publication of the WSPR article in QST, and I hope the site holds up under the new load. There are about 7500 active users of this site (meaning someone has registered, been activated, and subsequently logged in). About 600 of those have come since the publication of the QST article a week or two ago. As you can see from the Stats page, we are now seeing about 500 active call signs using WSPR on the bands each day. There are two main purposes of this site:

  • To be a repository for collection of WSPR spot data
  • To be a place for WSPR users to help each other, through creation of content, questions/answers on the forum, etc.

Heavyweight database queries are the biggest cause of occasional performance problems with this site. If you want to do a bunch of things which require heavy grinding through the whole history of spot data, please use the Downloads page to fetch the data you need and crunch on it locally. That being said, there are a number of enhancements which we hope to make to the site over time to provide more capability.

I also want to give special thanks to two fellow admins who have been managing user accounts for the last year or so. Lately, they have been doing a fabulous job of keeping up with the deluge of new users:

  • Trevor Smithers, G0KTN
  • Stu Phillips, K6TU

TX locks

Transmission locks on ignoring the TX time interval setting. When I use the tune control the TX stops at the set time interval. Signal is transmitted as I have confirmations from the database. I am using a TS-2000 with a Rigblaster Plus interface. Thanks for any advice.

Yeasu 817

Finally got the Yeasy 817 running, had to run the audio straight into the mic connector, running 1 watt into a tribander.

Magnetic Loop Antenna

Amazing! I tossed together a small magnetic loop that is working beyond my expectations. I took a piece of scrap 3/4" hardline 15 feet long and formed it into a 4 1/2' diameter loop. Stuck it on an old piece of PVC pipe with tie wraps. Made a coupling loop out of # 12 wire and a stub capacitor out of an old piece of RG-8. Propped it up against the fence in the backyard, about 4 feet above ground. I'm using it on 30 meters for the last few hours and getting spots from all over Europe and even Australia.
I must build one properly!

Wonder if my 40m horiz loop as a vertical on 160m will be heard?

I wonder if my 40m horiz loop as a vertical will be heard on 160m tonight. 4nec2 says it should have -21 dBi maximum gain.

AA4GT

I am on now I have to learn how to use this progrom.

Hi...

I´m testing today 10 m band... My signal has been received in Australia !!! is fine.. here only 5 w and windom dipole very close to the roof...
best 73 and enjoy WSPR mode... really is amazing.

WSPR 2.10 on Win 7 Pro

I use CAT (ICOM 756 Pro ci-v) for PTT and QSY.

The rigctl sub program fails to run
complaining about a missing libusb0.dll

Ham radio Deluxe 5.?? does not seem to need this
DLL to talk to the radio.

uninstalling 2.10 and reinstalling the old version
gets WSPR back on the air.

SoftRock RXTX Ensemble arrived

SoftRock RXTX Ensemble arrived today. Starting to build it up.
Meanwhile, I built a direct copy of a Alpha Delta DX-CC antenna, which is now installed at 10mtrs AGL.Working well with contacts into UAE and USA on 17mtrs and 15mtrs.

WSPR 2.10 on 64 bit Fedora Rawhide

Rawhide is the development branch of Fedora on which new
ideas are tried out before general release. At the moment
Rawhide is working with the Nvidia driver so I can run
Compiz and all that good stuff.

I used SVN to get the current WSPR code. After installing
required packages, WSPR compiled. I had to change permissions
on ttyS0 to allow regular users to use it with WSPR.

Only bug so far is a recurring one - the rig selection menu
does not display anything. I had to note the rig number from
the Windows version and type that number.

bin neu hier bei wspr

hallo
kann mir einer sagen wie das bei wpsr im ernstfall mit den qsl karten geht? oder fallen die hier ganz aus?

wenn ich der einzige bin der das nicht weiss, freue ich mich auch ueber eine direkte mail an
DL7Kat@web.de
will nicht unbedingt eine diskussion ausloesen
danke und 73
kat
