Chen, That's all true ... but the new software authors do not make that clear in their documentation. Some authors stick with 2125/2295 and fail to include a "reverse" or "invert" function to put Mar
Joe, Please contact me off the list ... I have information for you but your ISP is blocking e-mail from my ISP's mail server. Unfortunately, I can no longer use any of my alternate e-mail addresses t
Jim, ARRL and others promoting regulation by bandwidth have stated that the bandwidth limits are maximum and not minimum. Thus "conventional" RTTY would receive a significant expansion in the availab
Since the original language was mine ... "Freely available" is downloadable from a central site or available for the cost of postage and media. "Working software" is software that decodes all varian
Not on your life ... 160 has had problems for 30 years (ever since LORAN sharing went away) due to incompatible operating modes and usage. There aren't enough "gentlemen" who respect "gentlemen's' ag
No ... protocols do not do a bit of good if a vast majority of amateurs are not software developers with access to many thousands of dollars in development tools. With analog protocols (voice, CW an
Van, The FT-1000/FT-1000D has always had a fixed 10 KHz per revolution dial speed (100 KHz/revolution is the "fast" button is pushed). If one of your radios has a variable tuning rate, it has the Int
How absurd! If the average amateur cannot decode an interfering signal, how can he determine if the content is such that it NEEDS to be sent to the Commission for enforcement action (pornographic, c
Interference is not the only reason to refer a signal to the Commission seeking enforcement action. Unless you are advocating that the Amateur Service be turned into a quasi-commercial mobile servic
I am simply saying that in order for the Amateur Service to be effectively self- (or peer-) policing, the Commission has every right (and the duty) to permit the use of only protocols and modulation
Fro: Peter Laws: If you are going to change shift, why not make it 45 Hz or even 22.5 Hz (minimum shift keying) as advocated by JE3HHT? 170 Hz based on reducing the shift from 850 (170 = 850/5) as de
Absolutely not the case ... the FCC can prohibit the use of any protocol and/or any modulation system for any reason. If they wanted to require Amateurs in the US to use only International Morse in t
The STA work was all done at 200 Hz shift, 300 baud ... I was a member of that group in the mid-to late 80's. The STA was issued to ARRL and the results were the basis for the (misguided) rules that
The tube is rated for 2 KW anode dissipation with water cooling ... perhaps a water cooling system would significantly reduce the blower noise <G>. All the switching and filtering might be an issue
Not even RF detection but decoded band data and/or computer control. The decoding isn't so much the problem as the 2 of N selection matrix - particularly with the need to maintain isolation, etc. 73
It's not "good form" but it does not cause any harm other than resetting the "QSL date" if the data happens to match the other station's entry. 73, ... Joe, W4TV _____________________________________
Bill, If they're in my division and they're too busy to respond to my request for a QSL, they're too busy to represent me. I'll vote against them the next time. The non-QSLers should be posted somewh
It is also relatively easy to see when a particular station last uploaded logs from the LotW "home page" ... Terry's work is nice and I hope it causes some people (both League Officials and members)
John, It is likely that tone frequencies in your friend's Mark V Field do not correspond to the tones in his receive software. Assuming MMTTY: Demodulator: Mark 2125 Hz Shift 170 Hz AFC: AFC OFF (not
