[digitalradio] Weebly-warbly on 80m?
Listening this morning (Monday) in the UK on 3633 kHz at around 0300 UTC, I heard a strange weebly-warbly digital signal that continued for at least 15 minutes without a break (then it sent me to sleep). The striking characteristic of the signal was that the data rate was very low (a few bits per second?), and the transition between the tones wasn't sharp -- it seemed as if each tone glided gracefully up/down to the next. At first I thought it was ROS, but I haven't heard ROS like this before. Any ideas on provenance? -- 73 Ian, G3NRW

[digitalradio] Packet in the UK?
I'm catching up with what has happened to packet in the UK since I was last involved way back in 1999-2000, if anything. Are there any AX.25/TCP/IP networks/nodes/switches/BBSs still operational? Where can I find up-to-date information on networks, key players etc? -- 73 Ian, G3NRW

Re: [digitalradio] Opposing 60M proposal

Surely all that's important is to permit CW, SSB and narrow-band data (say, max 500 Hz) of *any* flavor that is permitted in Part97. Restricting data to just two or three modes is very short-sighted. If these modes become outdated, or ground-breaking new modes appear on the scene, you will have to keep going back to FCC to get the license conditions changed. -- 73 Ian, G3NRW

[digitalradio] Alinco DX70 on 5MHz?
I want to modify my Alinco DX70 for experimental digital transmissions on 5MHz. I have already discovered this: http://www.hampedia.net/alinco/dx-70th-tx-and-rx-mod.php It says that to "TX/RX everywhere remove both jumpers c and e", which seems straightforward. However, in my radio, jumper e is already missing, whereas in the black-and-white photo on the above site the jumper e is in place. So I want to be sure that jumpers c and e are indeed the right ones to remove -- the so-called "jumpers" are actually tiny SMD resistors, so I don't want to make a mistake. Has anyone here successfully done this modification, I wonder? -- 73 Ian, G3NRW

Unfortunately they are not really *emission* designations, describing just the characteristics of the *emitted* signal -- the designations also specify the *method* of generating the emitted signals and the *content* as well. This leads to the utterly ridiculous designations that you see in: http://life.itu.ch/radioclub/rr/ap01.htm Do you realize, for example, that when you are sending Morse code, the emission designator is now 100HA1AAN, and when you are talking on SSB the designation is 2K70J3EJN? (Incidentally, there is no mention of spread spectrum on that page). This is just codifying for the sake of codifying, and I do not believe the fine distinctions between method and content have any practical use. As technology continues to outstrip the legislators, the situation will only get worse. Bottom line is that to get things changed to something more meaningful and useful, you have to convince the ITU. This will not happen any time soon, so we are stuck for now with the useless designator mud pie. John, your mind is not feeble. You are applying common sense in a very non-common-sense world. -- 73 Ian, G3NRW

For Russian, under Windows XP, I switch to Code Page 28595 (ISO 8859-5) Cyrillic. As a general point, I wouldn't want you to expend a lot of coding effort in implementing Cyrillic support -- there are many far more important and interesting tasks for you to work on, I'm sure. My original question was simply to find out if any packages support Cyrillic out of the box -- it wasn't a directive to do some work!
