Ok Bob
All the Opera
qrg's are set as 'Dial
set USB'
The speed change , changes
the mid audio pass band of the decoder , but
the RX [ and TX ] Dial set remains the
same
In this case , If Markus
is trying to detect your signal with
correlation , it may be better to use
the exciter in CW mode and pick a
qrg inside the Op65 pass band ...that
means any other station , simply sets 73 K
usb op65 ..... using audio drive
the system places the carrier in the
lowest s/n 'slot' and
checks at each tx-rx-tx change over ,
not a problem for the Op decoder that
can track round 32 signals in the pass
band , is not ideal for correlation

Markus; I am following Graham's [G0NBD] instruction to move
higher. He said set upper sideband exciter to 73.000 and should be on
74.44-5 am not sure if actual transmit freq is 74.4 or if tone is 1500 hz so
would put me at 74.5. Have to get confirm of this from G. Graham you
read this e mail? Where should receiver be set for receive window?

Hi Bob,
I'd be interested
to set something up to catch Op-65 on 73 kHz. But I need to
know your actual RF frequency (not dial) - presumably not the
same 72.401 kHz as for QRSS?
Not sure
whether pseudorandom noise sidebands from the time-signal station
DCF77 will be a problem here.
Best 73,
Markus (DF6NM in JN59NJ)

Recovered from the psk-map
Substantial signal levels ! Op65 ~ -43 dB s/n , , thats +13 and 18 dB over the limit , range about 220 miles ? 20 watts would do !
