[digitalradio] NOSintro -- TCP/IP over Packet Radio is back on the web
Hello all. Following the resurgence of interest in NOS for emergency communications, particularly in the nos-bbs mailing list (https://www.tapr.org/cgi-bin/mailman/listinfo/nos-bbs), and requests from individuals enquiring about the book NOSintro, I have now re-posted the NOSintro web site: ~~ http://homepage.ntlworld.com/wadei/nosintro/nosintro.htm ~~ This is broadly as the site first appeared around 15 years ago (!), with many of the book's 35 chapters reproduced in full. I plan to post the remaining chapters as time allows. Please note that the book NOSintro has been out of print for many years, and I don't have any spare copies. I have no plans to have it reprinted in its present form. -- 73 Ian, G3NRW

Hi All, Tony sent me a fine set of wave files so I'll be able to do what I need to do.

Do I need to access the radio menu and change anything to get this to transmit? Thanks, Jerry WW0E
Re: [digitalradio] Interface
Jerry, Perhaps it is an interface made by Donner. I have 2 of them. Mine has 2 audio cables, the black one for connection to the line input for receive and the red one for audio out from the computer. It has a nine pin din for serial connection for rig control and the connector for either the Kenwood TS570 or Yaesu FT857D. Bob C.

[digitalradio] What mode is on 3.5820?
Anyone know what that seemingly never ending warble is around 3.582 tonight? It's fairly wide, around 300-400 hz wide...sort of a slow warble. Dave WB4IUY

[digitalradio] Connectors
Off topic, however I need some help with my connectors. I have my station connectorized with power poles and a Rigrunner distribution pannel. I find that with the Red and Black pair on the supply end and the corresponding Red and Black pair on the load end, it is possible to short circuit the powersupply if the connector pair is displaced to the left or right. I have tried using a -one up one down- of the tabs on the front of the conncctor pair to form a key, but when this is done on one end, the corresponding end cannot be configured in a matching manner because of the connector shell shows two tongues, where they shold be a tongue and a groove, therefore this connector pair cannot be mated together. I immagine I could remove the tongues and use super glue to hold one pair of connectors together. Does any one have any ideas or a better solution as to how I can solve this problem. 73 Stan N1ZX

[digitalradio] Re: What mode is on 3.5820?
Dave, were you in LSB at the time? Reason I ask, if you centered that signal on USB it would 3k up from your LSB frequency, being about 3.585. Assuming USB, that area is near a QRZ frequency* for ALE (automatic link establishment.) It's wider and seems to fit your description. Check out a vid I created and uploaded to YOUTUBE.com: http://www.youtube.com/watch?v=1cK_FGdu83s ... and let us know if that might be it. Intriguing mode and hope to use more of it. Just a little detective work here, so I could be wrong, but certainly love the hunt! f, k2ncc * http://hflink.com/channels/
