I captured this the day after I got my 6300. There's a ham less than a block away me. With my TS-530s and Softrock his SSB would destroy most of the 20m band. I mostly use digital modes in the lower part of the band and this has made 20m unusable. Of course with the Softrock, not only was 20m unusable but so was 40m. I knew the 6300 didn't have the preselectors, so I was expecting some disruption of the band. When I took this screen shot I was still getting familiar with the 6300 and hadn't set up any apps yet, but from the panadapter I think the lower part of the band will be ok. He hasn't been on since last weekend so I haven't been able to verify that assumption yet. My question is, how much difference would the preselectors make? What are my options if I want to try reducing this interference?
Even with the TS-530s I wasn't able to clearly understand him enough to get his callsign. I could with the Flex.
