[digitalradio] Monthly Digital Mode Sprint?
All, I think we could benefit by borrowing an idea from the NAQCC. The North American QRP CW Club runs a two hour Sprint each month that seems to bring a fair share of ops out of the woodwork. New members are always being added so they must be doing something right. A digital mode Sprint should show similar results and putting the emphasis on multi-mode contacts for additional points would take care of the modes that sit dormant. There's also the camaraderie and the opportunity to sharpen skills on modes that are less familiar. Just a thought... See http://www.arm-tek.net/~yoel/index.html Tony -K2MO

The same applies for the fldigi as it targets the second most HAM used operating system today. With pocketdigi I cannot expect much contribution even if I provided source code, because its target group is much smaller notwithstanding the fact, that the PDAs are often replaced by the tiny cheap diskless PCs. Actually, there seems to be a single contribution on the way for PocketDigi - one French sailor is fine tuning Amtor / NavTex. So there will be open source codec for flDigi and DM780, hi. 73, Vojtech

RE: [digitalradio] Re: The next big thing - Using Swarm Intelligence
Open interfaces can be as effective as open source. Look at what PSKCORE accomplished long before Moe AE4JY released it to open source. Mori-san JE3HHT's MMTTY has also been effective as a RTTY engine, and remains closed source but provides programmatic access to its functionality. 73, Dave, AA6YQ -Original Message- From: digitalradio@yahoogroups.com [mailto:digitalra...@yahoogroups.com]on Behalf Of Vojtech Bubnik Sent: Friday, May 01, 2009 8:57 AM To: digitalradio@yahoogroups.com Subject: [digitalradio] Re: The next big thing - Using Swarm Intelligence On the other hand I use free community software such a DotNetNuke where community collaboration has really worked I was a big proponent when I was a student.

RE: [digitalradio] Re:Solar Cycle 23 Sunspot Group Re-emerges
I agree, Marc. While there are theories, our present knowledge of solar physics provides no solid ground for predicting what may or may not be happening. Extrapolating empirical observations taken over the past few hundred years is risky, since they literally represent a quark in the bucket with respect to the sun's lifetime: http://en.wikipedia.org/wiki/File:Sunspot_Numbers.png Longer reconstructions based on geologic evidence indicate that there's more at work than a simple 11-year cycle with sporadic minimums: http://en.wikipedia.org/wiki/File:Sunspots_11000_years.svg How 'bout that peak at 9000 BC? 73, Dave, AA6YQ -Original Message- From: digitalradio@yahoogroups.com [mailto:digitalra...@yahoogroups.com]on Behalf Of Marc PD4U Sent: Friday, May 01, 2009 11:36 AM To: digitalradio@yahoogroups.com Subject: [digitalradio] Re:Solar Cycle 23 Sunspot Group Re-emerges But is the solar minimum the (only necessary and sufficient) explaining factor for a global cooling?

There simply is not enough data yet for either global cooling or global warming. A 100 year period could be simple blip in the geological climate record. The temperature data over the last few thousand years shows several temperature blips, both to the warm and the cold side, as well as a longer term warming trend coming out of the last ice age. Whether or not the data from the last 100 years means anything within this trend probably won't be clear for another century or two. -- All rights reversed.

Re: [digitalradio] Re: Ready for Q15X25 packet test ...
Based upon the modulation developed for WINMOR, is it fair to say that some of the wider and higher speed modes will be roughly equivalent to Q15X25? It still is perplexing to me as to why Q15X25 did so poorly (based on numerous comments from those that tried it) yet the modulation is surprisingly similar to other high speed modes. Comparing it to other modulation schemes that have automatic adaptability: Digital# of spacing baud modulation mode tones of tones rate Q15X25 15 125 Hz83.33QPSK Pactor 3 18 120 Hz100 QPSK - speed level 6 Pactor 3 14 120 Hz100 QPSK - speed level 4 Pactor 3 14 120 Hz 100 BPSK - speed level 3 WINMOR 15125 Hz 62.5 PSK/QAM WINMOR 15125 Hz 31.25 4FSK Could the answer be that was due to the fact that it can not scale for varying conditions? I have anecdotal comments that P3 rarely operates at SL6. Maybe others who have experience with P modes can give us some idea how often it needs to drop to lower levels. When that happens, it would seems reasonable that Q15X25 would not be possible to use. 73, Rick, KV9U There is no standalone versuion, you can find driver for Flex32 called soundmodem too.

RE: [digitalradio] Who Is Where Now : Idea, needs inventor
I suggest that the Mode column contain the Operating Mode, e.g. CW, Olivia, RTTY, Pactor3. We don't really care what mode a user's transceiver is set to... Having the each user's grid square and region (SA, NA-E, NA-M, NA-W, EU-E, EU-W, AF-N, AF-S, AS, AN, OC) would be helpful for beam heading and propagation purposes. If successful, a simple listing of online participants would be overwhelming. The ability to easily filter the list is fundamental, e.g. show me everyone QRV Olivia on 20m. 73, Dave, AA6YQ -Original Message- From: digitalradio@yahoogroups.com [mailto:digitalra...@yahoogroups.com]on Behalf Of Andy obrien Sent: Friday, May 01, 2009 7:00 PM To: digitalradio Subject: [digitalradio] Who Is Where Now : Idea, needs inventor Take at look at this fake web page http://www.obriensweb.com/whoiswhere.html I was thinking about the idea of a reverse DX cluster or an expansion of the concepts behind hrdlog.net .

You don't. What is happening is that YOU have software (probably MixW or DM780) that sees something like 73 and the software uses a waving-hand icon that is on your hard drive.

The groundwork to make more than half of this application work from a life feed from HRD is in my freely available software FreqMode2HRD. At least the part of the software that can listen to or take readings from the rig is all there. Once you have the data, forming an xml packet and shipping it off to a port via UDP is cake. It's a neat idea, but I'm zapped for time at this time. If it's reading from HRD, the logging program connection is moot.
