Nice instructional video. By using the Passband Tuning knobs, you can practically eliminate any atmospheric noise from the CW tone by using them independently. Turn PB1 one way, and turn PB2 the opposite putting a very steep skirt on both sides of the carrier frequency, rather than turning both passbands in sequence. Might want to give that try sometime. The IC-7300 is a joy to use and operate!
The result of doing that is the same as making the filter more narrow. You get the same results. Compare and see. I can't tell any difference. If you do that, watch the little window in the center get more narrow as you turn them in opposite directions. That center window is your passband. You still end up with the noise in the center.
Steve - Nice, clear explanations and advice. I think you might find the noise less objectionable if you used the onboard DSP from Icom. I use my NR all the time. It is best to leave it between 9 and 1130 on the dial - that way you don't over process the signal.
At last something I can apply to my 7300. I've been neglecting buying the darn thing because I found it to be lousy on cw. I haven't turned it on for 2 months and relying on my 756 PRO II.
This video is still relevant in 2022. I'm going to play with this tonight to attempt to help with noise issues. 73 de W5EN

Thanks for your expertise, just received IC 7300 looking forward to learning more from you

Thanks Steve. You're really helping me with my new IC-7300.
Tnx Steve! I really appreciate your videos! You are the reason I purchased my IC-7300.
Best regards, brian kn4r
Thanks Steve. Got my 7300 a couple of weeks ago. My first fancy rig ever. Enjoying your tips.
Good to hear from you Jim and congrats on the new fancy rig! Mine just keeps getting better.
