I was under the impression that CW (and Digital) were legal in the phone bands, not that I've ever tried them there. The problem isn't bandwidth as much as just plain poor operating practice. Automated stations should not be exempt from the rules, or common courtesy. 73 -- Lynn On 9/23/201

Just wait until the ARRL proposal for a 2.1 kHz digital mode bandwidth in the CW/digital segments passes. 2.1 KHz bandwidth ... try 3 to 5 KHz! I'm waiting on the Commission to post the proposal for comments - then I will object to the unregulated bandwidth *and* propose that RTTY/DATA be all

JT65A tends to be found at xx.076-xx.0785 and JT9 tends to be found at xx.0785-xx.080 on most HF bands (substitute 10.138, 18.102 and 24.917 for xx.076 on those bands). Note most RTTY collisions involve the RTTY folks who park on xx.080 Mark (FSK displaying mark frequency). Since space shifts d

It also works wonders to filter out loud PSK31 signals that are overloading your audio A to D converter. Too bad auto notch doesn't work in this situation. (I'd go after the strongest signal in the DSP filter pass band.) Cheers - Bill, AE6JV - On 9/23/13 at 6:23 AM, ma...@elecraft.com (Matt Z

Hi Bob, The K3's notch filter is designed to filter out CW signals. It's about 200 Hz wide, not much more than that. 73, matt On Mon, 23 Sep 2013 08:28:13 -0400, you wrote: >Howdy K3' people: > >I am looking at some signals I'd like notched out. I am using WSJTx, a >Data-Mode .On 30m there is
