PA0O with WSPR on 160 m

Here is an analysis of very interesting WSPR spots, that were made by Jaap PA0O. The spots were made from the 19th of oktober until the 12th of november 2015. The band was 160 meter. To reduce the length of the table, I only listed the stations that received more than 60 spots.

The strongest signal was received by G8DYK over a distance of 600 km. The longest distance was 6400 km, to N8OQ.

The lower the Calculated lowest possible power, the stronger the signal.
A Calculated lowest possible power of 1 milliwatt, means that a signal with a power of 1 milliwatt, should be received with a SNR of -29 dB. This is a solid copy in WSPR.

Spots over 2000 km or more.

Thanks Jaap for the interesting data.

The spots were made on 160 mtr, during daylight hours.
The lower the Lowest Possible Power, the better the propagation.

K5MQ WSPRs on 1.8 MHz with 1 W

I received a fine comment from Dave K5MQ on my previous post:
Dave further mentioned that he was using WSPR with a power of 1 W om 160 m.

 I usually run WSPR with 1 watt here. 
Have been on 160 meter WSPR the last few days. 
Have received a 3 stations from the UK, two at 5w and one at 20w. 
The furthest my 1 watt has been heard is VE6 at 2994km from my QTH in Lousiana.

Here is a table with spots from Daves 1W WSPR signal from the 16th to the 28th of February 2015.
The lower the Calculated Lowest possible power, the better the propagation.

How to read the table:
K9AN at a distance of 1000 kilometer, received Daves signal 143 times.
45 Of these spots were received with a SNR of about -9 dB.
So the Calculated Lowest possible power is 10 mW
The lower the Calculated Lowest possible power, the better the propagation.

Thanks to  Dave K5MQ.
It's my pleasure to make the WPA (WSPR propagation analysis)

* The Calculated lowest possible power is the power that could  by received with a SNR of -29 dB.
     The stronger the signal the lower the Calculated lowest possible power.  
     A signal with a SNR  of  -29 dB is a solid copy in WSPR.
