This is a shot of the 472 khz band with a 2.7 khz filter
This is a shot of the same band with a 100hz filter note the reduction in band noise between this and above.
This is a shot of the beacon band. My RX is tuned to SFB @ 410 khz I can easily tune the various beacons.
This is a shot of my local RF environment on this vertical from 30khz to 1700 khz. The hottest signal is about -43 dBm. The flag remains on SFB
I shot 3 more pics this morning
This pic shows the radio with 2 slices active. Slice A is tuned to the NDB beacons. The flag is on beacon A M. If you look in the waterfall You can clearly see the morse for A M. If you look up the band to around 408 you will see SFB. Again the morse is clearly visible. The Flex 6300 has a memory built into the waterfall. You can look back 10 minutes in time to see if a signal poked its head above the noise. This is great for monitoring for example the entire 6 meter band.
Here is a shot with 2 instances of CW skimmer active Skimmer really doesn't know what to do with the MCW. Also is presented a screen that reads out noise and signal for each segment digitally. My local time right now is high noon and my band noise @ 390 khz is -119 dBm Very cool!!
Here is a shot watching the entire 6 meter band while listening on 17 M to W1AW/0 in NE
I think the radio works fine in the 472 khz band.
