Hello DK7FC Stefan.

 

Congrats, but I am sorry because your LF WSPR signal is very strong here in JN19QB (about 180 µV in SPM3), and of course I cannot copy any other station when you are transmitting.

 

Please be kind to set your Tx traction as usual,  between 10 to 20 % instead of 50 %.

 

The goal of WSPR is to transmit with low power and also to listen the band for giving some RX reports to other transmitting stations.

 

It is the same problem, at times, when you are transmitting on OPERA 32 at 100 % without any pause for listening. In this case, others stations have no chance !

 

Best 73 and good luck.

 

Andy F6CNI.

So now i joined the WSPR group and start to do some test transmissions

with the normal 2 minute WSPR code, using Markus' tool. The goal is to

see if the tool works properly and what decode levels i can obtain in

various distances.

 

A 2 minute WSPR beacon is running here in Heidelberg / JN49IK, 50% TX

time. I will run it until tomorrow 6 UTC.

 

Reports apprechiated :-)

 

Please can we try to move the LF reports/hour peak in the diagram above

the level of the 20m band? ;-)

 

Tests using the 8 and 32 minute WSPR will follow soon.

 

73, Stefan/DK7FC

 

PS: TX pwr may be a bit reduced in first tests, abt. - 10 dB f.s.
