Unfortunately, those are also the hours where you won't find propagation on 3580. Or the middle of the night, when a working ham will probably be asleep for good reasons...

Re: [digitalradio] Re: An open letter: W1AW and 80m psk31 interference
Allow me to throw in one more thought... I believe we'd all be better off if the "machines" were segregated from the humans. This is an extension of the current flawed attended/unattended scheme. Let's keep one segment of an Amateur allocation reserved for all the manual usage and put the "machines" in what we used to call the unattended segment. Given that concept, the code practice sessions would be moved to the machine segment of the band... 73 Bill - WA7NWP On Fri, Sep 25, 2009 at 7:51 AM, Bill V WA7NWP wrote: >>> Why is the code practice sessons even needed now ?

Re: [digitalradio] Re: An open letter: W1AW and 80m psk31 interference
An over the air copy is much better practice. After all, you get the qrm/qrn/etc. in there, which is real stuff, and prepares people for radio copy, versus the perfect signal from a computer. Even better than the perfectly keyed copy from W1AW would be simply listening to some ops send - with hand keys. I use a straight hand key to teach code, then when the students hear perfect machine sent, their should be no problem in copying that.

When I was working on my Extra, I got myself up to speed listening to W1AW. I suspect that people still do that; who am I to tell them that they have to use a computer instead? Maybe they do it while driving to or from work; for a while, I did, and was happy to be able to do so. I grant that Morse proficiency no longer is required for licensing, but it certainly is required if one is to work CW, and I find the W1AW sessions to be useful in keeping my speed up when I don't have the opportunity to get on the air and pound brass. I'm not entirely happy with the ARRL, but I do appreciate this service -- though I very strongly wish they'd move the 80m transmissions away from the digital sub-band, and have told them so in no uncertain terms. -- Mike Andrews, W5EGO mi...@mikea.ath.cx Tired old sysadmin Announce your digital presence via our Interactive Sked Pages at http://www.obriensweb.com/sked Recommended digital mode software: Winwarbler, FLDIGI, DM780, or Multipsk Logging Software: DXKeeper or Ham Radio Deluxe.

In 1955 very few probably had tape recorders or an easy method to get perfect code practice.

It turns out that W1AW has been looking for alternative 80m cw frequencies for a while now. We just did not know about it. > I do question why this frequency was used as the primary PSK31 frequncy. In my opinion, the why isn't nearly as important as the fact that we have a problem on the band nowadays. The fixed frequency psk kits have been built and cannot easily be changed to another frequency. Why is an interesting question to prevent future problems like this, but we still need to find a solution for the current one. -- All rights reversed.
Re: [digitalradio] Re: An open letter: W1AW and 80m psk31 interference
I was about to reply to the question of why the choice of frequency for PSK31. I could not at the moment, but I see noone has addressed this point. It happens that 3.579545 MHz (NTSC color burst) were aboundant and rather cheap in the age of analog TV. So, they have been used in some designs I have seen of simple PSK equipment using the cristal for both carrier oscillator and pass band filters. If you have a "normal ham transceiver", that is tunable, well, just rock the dial, and that is all about it. Buth those simple rock-bound PSK transceivers cannot QSY. 73, Jose, CO2JA PS: Who uses a tunable radio Participe en Universidad 2010, del 8 al 12 de febrero de 2010 La Habana, Cuba http://www.universidad2010.cu - SEGUNDO SEMINARIO INTERNACIONAL LEGADO Y DIVERSIDAD.

Re: [digitalradio] Re: An open letter: W1AW and 80m psk31 interference(A dissent)
Far as I can tell, they have NEVER done that. That is a sore point to start with, but can you imagine a time when there is never a psk signal on that band (and the band is open?) I cant! The stupid part of it all is that the whole band is available for CW, so why cant they find someplace where there are no signals, and not near a narrow band signal? Another suggestion is on top of some ssb net that is just a bunch sitting around telling others to get off their freq especially when someone else was there first) There are lots of those useless nets.

Re: [digitalradio] Re: An open letter: W1AW and 80m psk31 interference
Like almost all large organizations with professional management, the ARRL has become devoted entirely to the perpetuation of itself. Paid public relations people write glowing statements expounding the dedication of the group to egalitarian principals, but to properly evaluate their motives you have to look at their actions, not their words. The ARRL is not dedicated to the benefit of Ham Radio, it is dedicated to the benefit of the ARRL.

I have found it frustrating when I am on that freq and THEN they start up. I wish they would simply QSY when the freq appears busy. Andy K3UK On 9/22/09, frankk2ncc wrote: > > > > That sounds like a very reasonable request. Well written and good job! > > f, k2ncc > > > -- Andy
