Phase / stability makes no difference to the Op
decoder performance , guard band
for OP64 is 100 mHz
, OP32 200 mHz , very unlikely to
drop within 200 mHz ! , 1 Hz
separation at OP64 could hold ~ 8
stations , afc will track the cross over's ,
plot would look like Clapham junction .
Good luck , 73-G,

Subject: LF: WE2XPQ OP32 136
WE2XPQ testing Op 32 136kHz - think Ive got the PTT and
controls keying now using the Ultimate 2 drive source - will hopefully be up to
600W in a few mins. Still driving the spiders out., so will let things warm up
slowly - around 35A loop current. Will see if Im phase continuous - the Tx is
"on" all the time and Im just switching the RF drive, Im justnot sure if
the gps driven freq stab/corrections occur when in Ulitmates "transmit"
mode. If so it may muck up the phase - We will see but Ive not seen
any transitions so far.
