Gus,

Getting a report from AA1A is amazing - really well done Gus. WSPR is remarkable with very low power signals.

As you may know, I have been using <1mW ERP for several weeks and have been heard by 27 stations in 5 countries with best DX 896kms. I now believe my ERP is approaching 2mW. I am hopeful that you will hear my tiny WSPR signal one night soon - maybe tonight overnight Gus?

Dear LF group,

After running beacon WSPR night 6-7 November with only 10 mW ERP (125 mW) TX power on 500 kHz it gives me great surprise, that a very long range can be achieved with extremely small power!

Dave AA1A got a decoding where the distance between us is 5756 km.

Also a number of EU stn’s reported decodes.

On previous occasions, with a power of 1 W ERP is Laurence KL1X/BY3A reported a number of decoding where the distance between us is 7284 km.

I would also like to thank the other reporting from the night's 10 mW broadcasts, and note that WSPR is a fashion which is particularly suitable for very low power!
