Re: [digitalradio] Re: Digital Frequency List - Bandplans.com

Dave, I think that busy detection can be valuable for kbd programs, especially if the algorithm gives a hint of mode. I will follow up with the SCAMP folks and see if I can get the code from them for use in gmfsk. Then hams can get some experience with how this feature might work, and get val

[digitalradio] Re:All Channels are Busy Channels? Free Decoding Rights?

You're right, Kevin, I should have said "many" instead of "most". The point still stands: at any point in time, not everyone has the equipment on hand to demodulate every mode. 73, Dave, AA6YQ --- In digitalradio@yahoogroups.com, Kevin O'Rorke <[EMAIL PROTECTED]> wrote: > > Dave Bern

You can speak or type any language you want as long as you identify in English if you are operating where the FCC is the controling entity. This question is in the FCC Technician Class License question pool and is addresses in Part 97. Walt/K5YFW -Original Message- From: digitalradio@y

Re: [digitalradio] Re: All Channels are Busy Channels? Free Decoding Rights?

Jon, It is legal to use a foreign language and many hams do this, however, Part 97 requires FCC licensed hams to ID using English. Using any language or code would be in violation of Part 97 if you were doing it "for the purpose of obscuring the meaning of any communication." Using Navaho, o

Doc and others... take it to the correct group. After seeing all of these posts, I know where the problem is. It's in the arrogance and close-mindedness of the few participants in this debate. Discussions over white noise, pink noise, frequency, channel... c'mon, be ashamed. Move on. This debate

[digitalradio] Re: on the status and practicality of busy frequency detectors

I don't believe the issue is secrecy; the author of SCAMP would likely share his experience with anyone interested in adding a busy frequency detector to his or her digital mode software. The impediment is a misalignment between cost and benefit. Were SCS to add busy frequency detection to thei

RE: [digitalradio] Technical descriptions of amateur radio data e missions

I suspect (knowing how government agencies work) that the FCC figures if a "mode" is being used in the public domain and if there is hardware needed to "read" the mode, and they can openly purchase the hardware to "read" them mode, then they aren't concerned with a complete published specification.

[digitalradio] Re:All Channels are Busy Channels? Free Decoding Rights?

This seems like a slippery slope, Doc. Should the FCC have disallowed SSB because when it was first introduced, most hams didn't have SSB demodulators and thus couldn't self-police? Demodulators for soundcard-based digital modes aren't free; they require a PC, a soundcard, and a receiver. Cons

What we need is a comparison table/Excel sheet of all the performance data, including weak signal.

Forget about the dictionary definition of channel. Federal Case Law has determined that a channel is: 1) the bandwidth necessary/required by a properly designed communications mode or RF signal. 2) the bandwidth allowed, assigned, or permitted by a U.S. Government regulatory entity. That would
