I'm back on WSPR now from Sydney.

I'm unable to engage in any other radio related activity due to other commitments. I wanted to still be involved so WSPR is it for now.

I've varied the output from my IC-703+ from 0.5 watt to 10 watts. As I am utilising the internal ATU I can only go by the power output reading on the radio. Output from the radio may in fact be less than 1 watt.

Does anyone know how accurate the "Po" (RF power output) reading on the IC703+ is?

Given the nature of my less than ideal non resonant wire I would imagine that radiated power would be minimal. Also, I've only had limited success with receiving signals from overseas (other than NZ/ZL). I've picked up 4 or 5 from the US, and the same number from Europe including the UK.

When I increased my radio output to 10 watts I was received by a couple of stations in the US. Other than that it's only been the east coast of Australia and a couple of spots by NZ/ZL stations. I'm being spotted by some NZ/ZL stations tonight with the radio set to .5 watt max output. This is fun!

I will be primarily operating PSK31 and other digital modes on 30m through the weekend but will WSPR when taking a break from the keyboard or operating voice on other bands. See

Expecting to be beaconing in WSPR mode on 28/50MHz during the next 24 hours when the Perseids meteor shower peaks. Would be interested to receive any reports.

A strong earthquake with a preliminary magnitude of 6.5 shook Shizuoka Prefecture, tuesday morning. There are no damage at Ant site of JQ2WDO and shack room. The quake was centered Suruga Bay, 80km to south-east of Fujinomiya-city, Shizuoka Pref.

As a newcomer to this mode I'm pleased to report that I now have successfully RXed and beacon TXed on 30m using WSPR and my signal is being reported from around Europe (no further yet!). At the moment I am using QRO (5W) into my 28MHz wire halo (via an ATU) which is not an effective 30m antenna, HI.

WSPR would be very useful on 10m as an indicator of marginal openings.

Visity my Home-Page under URL finde Magnetogram for my Latitude:

In the last few weeks I have operated from some places in France using my call and giving the QRA Locator of the spot.
So no I haven't lost my marbles and been giving wrong Locs.
Unfortunately WSPR does not send the full Locator or accept F/G3ZJO so often it appears that I did not move.

Some recent comments have been made regarding false info, I tend to agree that the whole system could be improved, as it is being slowly. At least reports of spots into the future are no longer accepted.

For reference operation was from.

June - Normandy JN091a

This this is my first day on WSPR, RX only (for the moment)
So I've been having a listen around the bands.

I've got a question, how can I check the accuracy of my RX/TX frequency ?

Thinking out loud , next week there is a very big meteor shower (Perseid), with some long bursts, It could be an idea have a 'play' on the high bands. The peak is on the morning of the 12th August, But it will be active a few days before and after.

During the last few days, I have been experimenting on 30 meters with output powers as low as 20 microwatts. No one has spotted my 20 microwatt signal yet, but K8CXM has spotted my 50 microwatt signal at a distance of 553 KM at 2332UTC, 05 AUG 09.

A 100 mW beacon with a step attenuator to an indoor doublet was used for all the tests. All equipment is homebrew and the output power is verified with a HP-432A Power Meter. If you look in the database the power is reported as 0.100 watt because it was too difficult to pull out and reprogram the beacon’s PIC controller chip for each change of power. In any case, there are no provisions to report power levels below 1 milliwatt to the WSPR database.

Other noteworthy spots:
100 uW - K8CXM, 2252UTC, 05 AUG 09, -23 dB, 553 KM
200 uW - AI4SA, 0530 UTC, 02 AUG 09, -21 dB, 333 KM
500 uW - NJ0U, multiple spots 31 JUL & 01 AUG 09, -28 dB to -20 dB, 716 KM
500 uW - K1JT, 1440 UTC, 31 JUL 09, -21 dB, 1215 KM
500 uW - W3HH, 1240 UTC, 31 JUL 09, -28 dB, 764 KM
5 mW – VK6DI, 2232 UTC, 05 DEC 08, -27 dB. 17,858 KM

Nice to see Chine fron Africa,
Also being heard by K1JT

I noticed on my pc a few days ago that I was running out of hard disk space despite the fact that I had not installed or saved anything large recently. I tracked the problem back to the folder where I keep the WSPR program.

The problem turned out to be that under the SAVE tag, the option SAVE ALL was selected rather than SAVE NONE. As a result, I had saved 8,300 .wmv audio files @2.3 MB each which took up 21.3 GB!

I have been running +37dBm to a G5RV @ 10M high. I have now dropped my output power to +33dBm and will be running this for the next 24 hours on 30M. Brad WF7T

Whisper with ATS-3b.

I implemented WSPR beacon transmit mode into ATS3bv-1.5 firmware. It is not the very first standalone WSPR beacon implementation, but it is the first WSPR beacon implementation for a stock
transceiver or transceiver kit. For those not familiar with Steve Weber KD1JV ATS-3b creation, it is a tiny 6 band CW/digital transceiver kit fitting into the Altoids tin.

My alternate firmware may be downloaded from

To get your ATS-3b rolling with WSPR, you will need to download ATS3bv-1.5 firmware, replace
beacon messages in the firmware with yours and flash your transceiver with the modified firmware. The beacon messages are generated by wsprgen application. wsprgen is a tiny windows application based on Mark VandeWettering's genwspr Python script.

I am just getting started with WSPR after reading about it in Radcom (journal of RSGB). I have receive only working at the moment using my FT-817 and SGC-2020. I will experiment with the different bands and see how I get on.
