Hi EE and Gang
Was wondering if EE/SunSdr can modify the software on receive for the MB1 software extended VHF freq to copy the WX stations on 165 MHz, it would be very welcomed by Many Hams here in America especially during Hurricane and Tornado season. Thank you all

Hi, Erik
Receiving of 160-240 MHz frequencies is the third Nyquist Zone for MB1 and SuNSDR2 PRO, ADC can receive up to 700 MHz.
Unfortunately, these radios do not have BPFs for these frequencies and if you'll receive a signal on them, it will be rejected by normal BPFs.
It's possible to receive signals at higher Nyquist Zones via ADC IN or XVTR connectors, but it's not supported in the ExpertSDR2, yet.
I added your suggestion to the wishlist, we might add it in the ExpertSDR2 1.3.
