Subject: LF: JT65-a and WSPR Test Friday
21 1800 . 2400 HRs
Will be running dual test , JT65-A
AND WSPR Friday night , 1800 /2400 ish
Frequency will be round 503 Khz , not yet
worked out the transmission format as the
wspr tx/rx ratio is round 10:1 , and
JT65-a 1:1 . this makes sequencing a problem.
If the drive levels are the same, looks may run
WSPR at 503.000 Ae fequency , and the JT65-a slightly above, in
parallel, setting the drive to give -3 db per tone, before onset of alc
action.
Tnx
