Tnx to all for the spots and comments on the recent 136 activity! Ill be running WSPR-15 for the next week or so if it continues to run satisfactorily under the XP compatibility mode. Even sequence,
Two T/A spots from Geoff, G0LUJ, last evening on 2200M at -35dB and -37dB show WSPR-15 to be a viable mode on 136 KHz. I will continue nightly WSPR-15 transmissions for the next week or so. Does anyo
Hi Domenico, LF I agree with you that EbNaut is the way to go for DX in LF. And QSOs can be made using short symbol durations at least equal to a long QRSS mode Would be interesting if you recall th
Hi Rob, Indeed, i have a suggestion. If you can transmit EbNaut messages, then let's try if it works. My RX is not overloaded any more. Due to the high QRN i gave up with the 17 kHz TA attempt . Las

Jay, Thanks for confirming that my current setup is actually getting out with a message that can be decoded! Ill continue transmitting this message over the weekend to test out everything in the tx c
Paul & LF, I am using an HP3325A with an external GPS-stabilized 10 MHz reference as the exciter for my current EbNaut transmissions on 2200m. The 3325 feeds my Hafler 9505 amplifier through a MiniCi
Hi Rob, Your first trials led to a new distance record for the mode on LF, well done! With the 11.9 dB at DF6NM you could have sent a 50 character message!! As Paul says, the constant phase in the 3

Markus, Thanks for the report! I will be glad to continue the test for several more nights if you can monitor on your end. Does your analysis indicate that an hour tx period is perhaps too long? Tnx
Hi Rob, Decoded your message here in Heidelberg, JN49IK from a small active E field antenna. See attachments. Some details: TX begin /UTC SNR / dB in 289 µHz carrier phase Eb/N0 [dB] 00:00 20.64 -18
