In case you are using SpecLab / opds correlation detection software, and decide to move down from 137.55 to 137.50 kHz band center, here's what you'll need to change:

- SpecLab FFT settings: reduce center freq by 50 Hz (eg. from 1550 to 1500 Hz) - SpecLab components, L2 blackbox, bandpass filter: reduce center freq by 50 Hz
- set up display range at left side of waterfall: eg. fc=1500, sp=106
- edit center freq in opds.ini from fc=137550 to fc=137500, and restart opds.

Best 73,
Markus (DF6NM)

For 136 , mid band is now 137.500 , decoder pass band +/- 50 Hz
