[digitalradio] Only using wide digital modes
Demetre, What you are recommending is completely unacceptable to 99.9% of all hams. Many of us operate various digital modes, both narrow and wide and in between. In the U.S., the text digital sub bands are anything that is not the voice/image sub bands. 73, Rick, KV9U Demetre SV1UY wrote: There is only a simple and logical solution. Don't operate anything else than wide digital in the digital subbands, just like noone in their right mind operates SSB in the CW portions of the bands.

In the U.S., the text digital sub bands are anything that is not the voice/image sub bands. People have been suggesting for years that a small area be designated for automated digital (Pactor, in other words). The Pactor guys have refused. THEY are the ones who insist that wherever digital can go, Pactor can go. The only solution is to do what I do--if a Pactor signal comes on freq, up the power until he has to stop. It works.

And is strictly illegal by Part 97. 5 KW linears are available. Want the address? No wonder why Hollingsworth spends so much time in California.

It is illegal to start on low power and increase the power to maintain a contact on what was a clear channel at the beginning of the QSO? Do you have a cite for that proposition? I would love to see it. de Roger W6VZV

Your statement was that you would increase power to interfere with him/her deliberately.

I said that I would increase power to keep the Pactor station from taking the frequency. By the way, I don't imagine in your investigation of the facts (of which there is none) that you are aware that SCS Pactor modems do that *automatically* ... if the link slows down (say, because there is a live QSO on frequency interfering with them) they increase power automatically. By your analysis this is illegal, of course. But since that is a robot station doing it, of course that is OK with you. de Roger W6VZV
Re: [digitalradio] Only using wide digital modes
One question Roger. How do I get my SCS TNC to automatically increase power John At 06:54 PM 10/14/2007, you wrote: Wrong.

Re: [digitalradio] Only using wide digital modes
The fact is that SCS modems REDUCE the power to what is just needed to keep the link. If QRM shows up, the modem will just attempt to maintain the needed SNR. And it is not done ONLY in the PMBO but also on the user end. I have seen powers as low as 5 watts with a 100 watts radio. Jose, CO2JA --- Roger J.
