The Weak Signal Propagation Reporter Network is a group of amateur radio operators using K1JT's MEPT_JT digital mode to probe radio frequency propagation conditions using very low power (QRP/QRPp) transmissions. The software is open source, and the data collected are available to the public through this site.

Please note 80m frequency change to 3.5686 MHz (USB)

Please note, the WSPRNet site has been updated to reflect the change to the 80m WSPR frequency which is now 3.568600 MHz USB.

Thank you to K1JT and G4ZFQ for pointing this out.

[From Admins] Map issue -- a fix of sorts

The issue with the Google Maps is related to the change Google made on July 16th, 2018 that severely curtails the free API limits. WSPRNet will be transitioning to an alternative mapping solution as soon as possible.

In the interim I have added a new field to the User Profile form for storing your own Google Maps API Key, if you want to get back to the way things were. You can get your own API Key by following the link below and I would strongly encourage you to read the Q&A down the page.

1) We can't receive second and higher harmonics of WSPR signal because
a) Subband's WSPR is not multiply on different bands.
Example: CW Signal 7030 KHz, second harmonic is 14060 KHz may be received by skimmers or operators.
WSPR signal 7040.100, second harmonic is 14.080.200 and not in 14.097.000...14.097.200 subband.
b) Four frequences of WSPR signal will have wider step in higher harmonics and could not be decoded.
See WIDER-2F-wspr.PNG

due to the situation that hams have to use two different frequencies for wspr activity on 60m, I tried to configure my equipment for decoding both signals at the same time. In Austria only RX is permitted on 60m :(
Flexradio 6300:
Slice 1: RX - Audio DAX RX1 - SmartSDR COM 4
Slice 2: RX - Audio DAX RX2 - SmartSDR COM 5
more tricky was to start wsjt-x in two instances.
Thanks ve2ebk for the post in groups.io FT8 Blog.
first instance in the windows cmd window with wsjtx
second instance with wsjtx -r=2

Finally a first active night on 160m with 213 UNIQUE dx spots "across the pond" by 53 spotters (NA+EU).
Recall of the previous season, first active night: Dec05-2017 258 UNIQUE dx spots.

Best RX stations of the night:
- SM4GOJ(15NA), GM4OAS(14NA), G8DYK(12NA), PA0O(11NA), PD0OHW(11NA), F59706(9NA), TF3Z(9NA), G0LUJ(7NA), OZ2JBR(7NA), AD5GH(6EU)

Good luck all,

In conjunction with the 6m WSPR Group on Facebook, we have conducted a trial run of some awards for 6m WSPR operators in Australia during November. This was quite successful.

For December a similar awards scheme will be on offer. Awards are -

December 6m WSPR Two-Way Reports Top 5 -
The top 5 Australian stations as listed on the KB9AMG database will be eligible to claim the following gift voucher values as an award for their efforts. Vouchers can be from electronics, hardware, grocery stores etc.
1st $50, 2nd $40, 3rd $40, 4th $30, 5th $30.

Hello I'm learning how to post a report on this site. Could someone here show me how. I've been posting my posts on the wspr site in Twitter to Chris Fallen. Thx in advance Ve6gpt Gord

The spots from 17:54z to 18:46z (24 Nov.) were in MF, not LF band. Sorry.

Though I signed up over 2 years ago, I finally got everything configured and am on the air on WSPR. Putting out 1w for now through my end fed sloper. Hope to see a lot of data over the next period of time to help me understand how this station works.

I have been posting reports for 30M using my KiwiSDR and a 30 Meter loaded whip. Considering the band conditions, I have been pleased to see reports from up and down the west coast.

Heard Joe 8yrs ago ,update to the software display are magic. 73 good wspring

Now trying out a home brew mag loop based on the G4ILO Wonder Loop.

Hi.
I just released my new WSPR Desktop transmitter.
It is an open source Arduino based transmitter just like the previous one.
This one comes built in a box with four low pass filters and covers either 137kHz-3,8MHz or 7-18MHz or 21-50MHz depending on what model you order.

Configured from a PC software but will operate standalone using it's built in GPS for time keeping and position.
Powered from 5V USB so it suitable both for the shack and on the road or hike.

Like many other WSPR'ers I have gone SDR. Recent 3 band spots have been from a KiwiSDR , a nice tool.
But from now on (5th November 2018) the RX is a Red Pitaya board running Pavel Demin's exceptional software on eight bands LF and up, I will continue using my 50cm. E field antenna which works very well and is almost invisible. Pavel has been very kind in assisting me over a silly set up error that came from You Tube!
