The SunSDR2 PRO is extremely sensitive with performance similar to ANAN-100. With the 10 dB preamp turned on you can expect MDS figures better than -131 dBm and up to -136 dBm on some bands. On the 2m band I could hear a signal at -140 dBm which is exceptional. This would make the radio a real contender for weak signal work on the 2m band.
