- не хуже, и не лучше RSP.
А что такое RSP?
Луис И Карлос провели интересный эксперимент:
Interesting test last night. Thank you Carlos
Started with WSPR-2 at 22:14 and the very first transmissions were received by Mario, LU8DPM
It was still no full sunset at Mario's QTH !!
2020-11-02 22:22 EA5DOM 0.475650 -30 0 IM98wn 1 LU8DPM GF03ng 10311 223 2
2020-11-02 22:14 EA5DOM 0.475652 -29 0 IM98wn 1 LU8DPM GF03ng 10311 223 2
After that, Mario reported noise increase and no more decodes in WSPR-2 were reported
Then I changed mode to FST4W-300 and let the Tx running overnight
At 00:00 got the first reports from both of you in FST4W-300

More decodes followed. You can see the S/N difference from you and Mario

Only 3dB difference at 00:45
During the rest of the night only few decodes from Mario in FST4W-300 untill 01:15 which was the last one
2020-11-03 01:15 EA5DOM 0.475646 -33 0 IM98wn 1 LU8DPM GF03ng 10311 223 5
2020-11-03 01:05 EA5DOM 0.475646 -35 0 IM98wn 1 LU8DPM GF03ng 10311 223 5
At 05:00 woke up and decided to change to WSPR-2 untill sunrise. At 05:42 got again decodes from Mario in WSPR-2
2020-11-03 05:48 EA5DOM 0.475647 -32 0 IM98wn 1 LU8DPM GF03ng 10311 223 2
2020-11-03 05:42 EA5DOM 0.475647 -23 0 IM98wn 1 LU8DPM GF03ng 10311 223 2
But the most interesting is that I got also one decode from you at limit and in WSPR-2
2020-11-03 05:58 EA5DOM 0.475647 -33 0 IM98wn 1 LU8DQ GF15ab 10108 224 2
This was one and only. Mario even reported a new one at 06:16 and then I got sunrise here
2020-11-03 06:16 EA5DOM 0.475646 -30 0 IM98wn 1 LU8DPM GF03ng 10311 223 2
2020-11-03 05:58 EA5DOM 0.475647 -31 0 IM98wn 1 LU8DPM GF03ng 10311 223 2
It would be very useful to combine WSPR-2 and FST4W-300 transmissions but can't see a clear way to do it
Does it really worth to use the 5 minutes mode over 2 minutes mode in MF ?
Keep tuned. Further testing needed
