I like to do a little AM BCB DX'ing so I was playing around with my 6300 on the BCB late last night. I was pleasantly surprised, it is very very good, excellent sensitivity and the selectivity (along with the use of LSB/USB) allows easy copy of stations buried 10 kHz away from a local powerhouse 700 WLW. Additionally the NB completely removed my local line noise without distorting the signal. It's a very good SWL/BCB receiver. Thanks Flex!
