Rob,
abt  the three modes relative
I understand intuitively what is the best EbNaut. But with character longer than 4-5 seconds
OP32 with Deep Search (idea by DF6NM) is now very well RX now. I believe that not much worse OPDS32 by DF6NM
WSPR15 takes a little worse than OP32 with Deep Search. But much better than WSPR2
EbNaut need for substantially better performance TX/RX. I'm going to do this for the next season

Alex,

Your multi beacon is a great tool for the 2200m LF Band!  I’d be interested in learning about your design and implementation approach for the multi beacon.

Do you have any information on the weak-signal performance of the three modes relative to each other?

Thanks again for putting your beacon on the band.

73,
Rob - K3RWR
