I wish you luck! (I'd like to see that as well. The NDB band is pretty crowded here too!) 73, Ken Alexander VE3HLS From: david via Groups.Io <zinc65@...> To: main@SDR-Radio.groups.io Sent: Tuesday, April 10, 2018 6:42 AM Subject: [SDR-Radio] Manual Notch Please Sir, I know you are busy, and there are lots of requests flying around for new, exotic features. But, can you bring the creation of a manual notch near to the top of your list? The attached screenshot illustrates the issue. The waterfall resolution is good enough to read the morse ident (PST), in this case. But the surrounding carriers make it impossible to extract any audio other than the carriers. I'm getting on very well with the rest of the package. I even came to terms with the scheduler, and using NB2 makes huge improvements to code reception. But these carriers close to code signals make some reception impossible, even with narrow filters at maximum length. And no, the auto notch doesn't help. Best Wishes David, GM8XBZ |
