Thanks for opds settings.
Sorry – I have to ask for explanation “Opera software users should tune to 72.8 kHz dial”
Should opds users also set 72.8 dial? If not, then can’t run Opera and opds in parallel from same Rx.
If so, do I also change the additional SL settings (that worked FB last night for OP 16):
CF=1622
RF Offset 72.7 to 72.8

Bob and Dex intend to transmit Opera-64 tonight, WG4XRS on 74.3213 and WG5XRS on 74.3229 kHz.
Opera software users should tune to 72.8 kHz dial to bring the signals inside the prescribed Op-64 passband.
Opds users can start out from Op-16 settings, but reduce FFT bin size by a factor of four from 0.954 mHz to 0.238 mHz.
Example settings for SpecLab with opds-64:
FFT decimation divisor 768,
scroll interval: 20 minutes,
number of exported bins: 32768,
untick use INTEGER numbers only.
Example parameters for opds.ini:
opspeed=64
spotdelay=58 ' seconds
fc=74322 ' center frequency (Hz)
sr=12000.86 'enter your calibrated samplerate (Hz)
dec=50331648 '768*64k
