Re: LF: R7NT multibeacon

[Alex R7NT <r7nt.73@gmail.com>]

Rob,

I have DDS VFO and original sofware by Alex RN3AUS  rn3aus.narod.ru/dds_tx/index.html (maybe online translate from RU to EN?)

scheme http://136.su/index.php?action="">

The program can also work as a multibeacon through the text sequence from the txt-file. For example, there was such a cyclogram for this multibeacon

[1]

FREQ=137602

MODE=WSPR

DOT=15

[2]

MODE=EbNaut

DOT=2                  ***Symbol 2s

CODE=8K19A

CRC=16

TIME=hh:14:55      ***Start time from hh:15

MSG=R7NT

FREQ=137541

[3]

FREQ=137541

MODE=OP-32

RUNTIME=1730  ***1730s 28min 17s - not 32min !

[4]

NEXT=1

REPEAT=30   ***30 times from [1] to [4]

[5]

MODE=STOP

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,
