Opera deep search users,
 
here are some details on how=20 to adapt opds to the new Op-2H mode for 29.5 kHz.
 
If you are using an USB receiver, = you=20 could tune to 27.98 kHz *** dial and process the audio band = around=20 1.52 *** kHz. This will put Bob's QRG near the middle of  = the=20 passband of standard Opera software, so if you want you can = run both side=20 by side. The=20 following settings will then let opds analyze a 3.9 Hz wide = passband=20 centered on 29.500 kHz:
 
Audio samplerate:=20 12000 Hz
FFT decimate (divisor):=20 1536
FFT length: 65536  (119.2 =B5Hz bin width).
FFT center frequency: 1520 Hz  *** =
Number of exported FFT bins: = 32768
Waterfall scroll interval: 30 = minutes
L2 bandpass filter before noise = blanker: center=20 1520 Hz ****
 
**** Note: According to later info, = Opera -2H=20 actually wants 1550 ... 1600 Hz audio. So if you like to run Opera and = opds on=20 the same receiver, you should select 1575 Hz for SpecLab's center = frequency=20 and filter, and tune to 27.925 Hz USB "dial".
 
In opds.ini, the following lines need = to be=20 edited:
 
opspeed=3D128     = 'Op-2H speed=20 (approx. minutes)
spotdelay=3D116   'delay spot timestamp = the same=20 way as Opera (seconds)
fc=3D29500      =      'FFT=20 center frequency=20 (Hz)
sr=3D12000         =   'your=20 calibrated samplerate (Hz)
dec=3D100663296  '1536*64K decimation = * FFT=20 length
 
Many built-in soundcards are now = supporting 96 kHz=20 ADC samplerate. If you own one of these, the much prefered option would = be to=20 connect the antenna directly to the soundcard, doing away with the = receiver and=20 it's possible drift. In SpecLab, = you=20 would then directly enter 29500 Hz center frequency for the = bandpass=20 and the FFT, select an approximately 8x higher FFT = decimator from=20 the dropdown list (13824 instead of 1536), and modify the dec = factor=20 in opds.ini accordingly (dec=3D905969664). You=20 can then use samplerate correction with one of the military MSK = stations to=20 remove any remaining drift.
 
Finally you will have to enter = potential=20 transmitting stations to the search list callsloc.txt:
 
WH1XBA fn12lq
WH2XBA = fn42hi
WH3XBA=20 fn31ls
WH4XBA em95tg
