Vey nice test Andy. Thank you for sharing your results
 
I'm also transmitting QRPPP (may be with one more "P") with just the Ultimate-3 connected to antenna
 
Have been using a vertical 11m high without coil. But last week I finally installed a 70m perimeter loop
and managed to get it tuned to 477KHz. On my monitor at 7Km I have imporved by 10dB with the loop
 
I'm transmitting WSPR-2 and Opera8. So far have got my first (and only) WSPR report from about 500Km
at David EA1FAQ. And last night got a few decodes from Iban EB3FRN
 
I don´t know which is my ERP. But can be probably well under 1mW  ??
 
Next step is an small 25W PA. But for the moment will keep on QRPPP

Congratulations. QRPPP is certainly fun and a real challenge for the RX stations.

Muchas gracias Iban.
 
last 3 nights I tested 20, 1 and 0.1 milliwatt ERP. Here the results :
 
Date night ERP mW  Total Spots received me Total stations received me Max QRB km
April 24 / 25 20 370 21 1284
April 25 / 26 1 45 9 730
April 26 / 27 0,1 19 5 587
 
To night, I’ll be QRV with 0,05 Watts ( 50 micro Watt).
 
Best 73 to all.

HI all.

 

Last night, I tested WSPR 2 MF using 1 milli Watt ERP transmission : 1 Watt output TX, 12 dB attenuator and – 18 dB antenna efficiency.

 

Thanks to the 8 differents stations reports :

To night, same test but using a 22 dB attenuator instead of the 12 db. The ERP be around 0.1 milli Watt (100 micro Watt). A new challenge.

 

I hope some reports coming from 2200 to 0400 TU...

 

73 to all.
