The graphical display of WSPR shows the short path from stations in Europe to Australia in the morning (at 7 a.m. UTC) for the 30 m band. However, I have the feeling that these contacts were transmitted via the long path.

This line in the database makes my heart a little jump :-)

All with just 5 watts on 20 mtrs. wire under the house-top!

fantastic, what could be done with such a setup!

WSPRnet opens up the possibility to measure the efficiency of my magnetic antenna (1m diameter), which stands on a balcony. Radiation in west direction (up to the zenith) is unobstructed in contrast to the east, south and north direction, where the antenna is near (1-2m) iron concrete walls with a hight of 10m. I compared the reception reports of my station (DL1MMK) with DG7RJ (distance 20 km), who uses a homemade Dipole 2*9m at 7.5m heights in SW/NE direction.

For the 30 m band:
Transmitting efficiency: In west direction (long path) the report by VK7ZL (23457 km) is 6,5db better for DG7RJ as compared to DL1MMK.
In west direction the report by W3HH (7930 km) is 5 db better for DG7RJ as compared to DL1MMK.
In south east direction (4Z4TJ) DL1MMK is received with -18 db as compared to DG7RJ.
In north east east direction (RK3IK) this difference is - 15 db.
Receiving efficiency: Interestingly DL1MMK receives W3HH with the same signal to noise ratio as DG7RJ.

For the 40 m band:
Here the theoretical efficiency of the magnetic antenna is reduced -4db. Consistently K1JT receives DL1MMK (transmitting west) now 12 db worse than DL1MMK receives K1JT (see file).

Hi all. Phase 8 was completed sucessfully yesterday evening. Hope to find the time to continue with the rest this week. So far no big issues except some human failure ... hihi. I ordered a nice aluminium case for the kit and also a E-MU0202 soundcard.
Have a good start in the new week!

Let's see what's happening...

I've taken over the living room table, set up the FT-817 and run the feeder out to my portable dipole in the garden.
It is all working! K9OHI, AC2C, IQ4DJ on 30m.

Clever things these computers.

Hello Fans
I coded a little tool to copy WSPRnet Database Spots into DX-Atlas World-Map
with splitting TX and RX Spots of your Call.

You can toggle between TX and RX Spots at the World-Map to interpret something …

Good morning!
I completed the phase 5 of my G3020 kit. Hopefully I find so much time to build the next days as I did last week to get on the air with the G3020 soon. I would be interested to get some information fromt he ones of you that use G3020 og G40 which soundcard you use and which SDR software you prefer.
Thanks for your comments.

Finding this new (to me) part of the hobby VERY interesting.. Amazing who and what time of the day you can be heard around the globe!!

I think that this will really help ( or inspire) me to understand propogation more.
