RE: [digitalradio] Pskmail Server in U.S.
The first mult-protocol pskmail gateway is now in testing. At DA5UWG we have an XNet server running on the pskmail server, which functions as a pskmail/AX25 gateway to pactor transport links on 20/15m , to the db0pdf packet digipeater, and to the IGate packet network. 73, Rein PA0R -Ursprüngliche Nachricht- Von: Rud Merriam k5...@arrl.net Gesendet: 18.05.09 02:19:24 An: digitalradio@yahoogroups.com Betreff: RE: [digitalradio] Pskmail Server in U.S. I'll have to agree with Russell that I have not seen hostility here toward packet. If I may offer some constructive criticism, not meant as an attack. When you start a message with what you have is nice but WE have... you are likely to engender a defensive reaction. Addressing the issue of packet, you certainly are aware that better protocols exist for use on HF. That is one of the goals of ham radio to experiment and develop new technologies. PSKMail is a very positive illustration of this. They created one means of providing a messaging capability that has evolved to utilize new capabilities as they became available. The NBEMS is similarly positioned to lever new developments. Packet has technical shortcomings that have been addressed by other protocols.

As it stands today, the Skipnets transport miscellaneous bulletin traffic to keep the system exercised. There is some personal messaging, but there is a great deal of underutilized capacity for more point-to-point messaging between amateurs. No non-ham or 3rd-party traffic is transported by the Skipnets, but ham-to-ham communications are definately encouraged. A new HF network roughly modeled on the SkipNets is currently under development, but the first servers will probably not appear for some months yet. There are still numerous issues to resolve.

Re: [digitalradio] Propagation: 20M all day now with digital modes?
Andy, With a slight improvement in the solar flux numbers and the longer periods of sunlight in the northern hemisphere, I wonder if we are at the point that 24 hour per day will be common using the robust weak signal digital modes? I think you have it right Andy. Ionospheric models show that the 20 meter band stays open much longer in summer than in winter, especially for locations within the northern hemisphere. A few paths come close to being open for 16 hours or more. The predictions also say that this happens regardless of where we are in the solar cycle and it all seems to correspond well with on-air experience. It seems logical since the summertime ionosphere is exposed to more direct sunlight for much longer periods of time. The polar ionosphere would seem to benefit most from summertime illumination. It seems possible that a slight variation in the 10.7cm solar flux could have some influence on propagation, but I would imagine it's much less significant compared to the seasonal changes. I've learned that it doesn't always go hand-in-hand with conditions and is often misleading... Quoting Robert Brown (NM7M) ... the 10.7 cm. flux has its purpose, indicating the presence of active regions, and it is a mistake to think that changes in that flux are always associated directly with the state of our ionosphere. I have been able to work Europe on low power with a vertical as early as 0800 hrs, in the past month Europe did not usually open until around 1200 UTC. That's a near perfect match to VOACAP's NY-EU predictions. The predicted 20 meter band openings start around 12:00Z in January and they slowly creep up to 08:00Z in May. I have been heard in North Carolina at 0730 hrs UTC the past couple of mornings using JT65A Could be residual F-region ionization left over from the daylight hours - possibly Sporadic-E. easy QSO conditions with ZL2BLQ on 20M (CW) around 0200 UTC Nice one Andy - the time coincides with VOACAP. The band is supposed to peak between 0200 and 0400z.

Re: [digitalradio] Sound card systems for ARES
While we are not there yet, things have improved over the past year or so. You could use packet, but it is a mode that requires very good signals to work. The only sound card packet program without an expected cost is Multipsk. It supports 300 and 1200 baud packet. Multipsk also has the FAE/FAE400 modes that can work with much weaker signals in a full ARQ mode. Not as fast as packet with good signals, but moderate speed is better than zero throughput when conditions get more difficult. Supports both peer to peer chat and messaging, but no e-mail. The NBEMS system (fldigi + flarq) will provide ARQ messaging with several modes but will not support ARQ peer to peer chat which may be important when involved in public service/emergency communications. Their philosophy does not support e-mail. The PSKmail system can provide e-mail (limited number of servers at this time if you are in the U.S.) but if using the Linux client, can also provide ARQ peer to peer. This is planned to be added to the Windows version. I don't know of any other interest from developers who are planning to add peer to peer digital communication in one software program. Winlink 2000 is developing a sound card mode to work with their e-mail system but their philosophy does not support HF peer to peer connections, so the software will have very limited use for practical public service/emergency communication where you need to send messages between peers since you may not have the infrastructure remaining for mail systems. The ideal from my perspective would be to have an easily understandable sound card software program that works on HF or VHF, handles peer to peer traffic as well as e-mail, and adapts to the conditions with appropriate protocols. We are beginning to have the pieces, but no one has bolted them together into one system, HI. Easy to say, but not easy to do. The closest thing that I can see is PSKmail using WINMOR or something similar as the adaptive protocol. That would be a killer digital program for public service/emergency use. 73, Rick, KV9U Lee wrote: Hello Folks, I am looking for what you have used or have read about.

[digitalradio] Save Priority Settings In Task Manager
All, Prio is a program that allows you to save the priority of a process in Task Manager. Windows changes the priority to the default once the application is closed so it will not save your preference. They say that changing the priority to a higher setting may help with some applications that need more processing power. It might help if your digital mode software is running a bit choppy. http://www.prnwatch.com/prio.html Works with WindowsXP / Vista.

Re: [digitalradio] Re: Sound card systems for ARES
NBEMS is the only application that would meet your DEC's requirements, find it within the latest implementing of FLDIGI. It contains ARQ PSK31, ARQ MFSK16 and a few other modes. Also facilitates email exchanges on a point to point basis with the ability to drop email off in to the Internet. It is all free. Then, in a few weeks time (maybe couple of months) expect Winmor to be added to the Winkink system. Winkink currently handles files and email via packet radio and Pactor. Pactor II and Pactor III require expensive TNC's but Winmor will allow sound card digital applications to connect to a server on HF. Thus, with NBEMS you have a very easy system of point to point error correcting communication. With Winmor and Packet in Winlink , you have the ability to do everything else. The two combined will be about as elaborate as hams can get, ALE systems notwithstanding. Andy K3UK
[digitalradio] Re: Sending MFSK16 Images with DM780
how do you send pictures with HRD/DM780?? Create a macro with the send-pic command. A window will open when the macro is sent. Open the image you want to send and choose Grey to send in black-and-white - the default is color. The image will go out automatically. The image size / transmit time can be changed by resizing the send window. The pixel size and the time is displayed at the top of the window. Larger images will need to be resized. You can also insert an image into a CQ macro with DM780 - see below Tony -K2MO CQ CQ de YOURCALL send-pic CQ CQ de YOURCALL pse kkk stop

RE: [digitalradio] Question for the Linux gurus
Hi Dave, First would be to make sure there really isn't support for it. If you can get to a bash shell, and get logged in as root, you can run ifconfig, and see if it lists the USB ethernet adapter. I say this from the perspective of an even older laptop, for which I had (of all things) a parallel port to ethernet adapter - and the installation I did recognized the presence of the adapter, and initialized it. Run ifconfig -a and note what interfaces it comes up with - probably just the loopback interface, but if the laptop has an infrared port, it might also be reported. Then plug in the USB ethernet dongle, wait 10-15 seconds for Linux to enumerate the device, or if you're running from CD, perhaps longer - wait for the CDROM drive to spin down? Then run ifconfig -a again and see if there's a new interface. At that point, if it's connected to a network with a dhcp server, you'll probably have a working network connection.

RE: [digitalradio] Question for the Linux gurus
Thanks, Bob! The question has been rendered moot, however, as I opted to sell the laptop. It would have taken too much money paid out for memory to make it a viable machine, and even then it would have only had 256M of RAM. As a side note, I loaded XUBUNTU on it, and it worked. It took five minutes to open an application, but it worked! It even recognized the Ethernet adapter! It just wasn't worth investing any money in at this stage.

If you want XP, microcenter has hp mini's refurbs with 1.6g intel atom, a gig of ram, etc for $229. Full sized keyboard, which is my only nit with the eee's.

Re: [digitalradio] Re: Sound card systems for ARES
Andy, While you could use different systems, it gets very, very complicated for non-digitally oriented hams. Just take some one who has never used this stuff and really is not all that interested, but needs to use it anyway and you will see how challenging it can be, HI. Winlink 2000, even with WINMOR, is not going to help them much either since it does not support the critically needed peer to peer function on HF. Some might think you can somehow use packet radio on VHF but in our area that might give you 15 miles in some directions, so is not very practical. We must have NVIS for practical Section and Regional communications. The only sound card system that can actually do what they want on HF really does seem to be PSKmail although I would consider it somewhat nascent here in the U.S. at this point. I am even toying with setting up a server here in Wisconsin, but not so much because of my central location, but mostly for experimental use, public service potential and certainly emergency use when the peer function is added to the Windows version. As you know, I have not been able to find a Linux distribution that works adequately on my equipment. With the recent release of Ubuntu 9.04, this may be solved after all these many years. While most hams will not consider Linux at this time, and it does have its shortcomings, it does have some advantages and would be needed to operate a PSKmail server station. The really neat thing about all this is that we are coming closer to some really good solutions for casual use and public service use of digital technology. And anything that you expect to work during an emergency, must be regularly used on a frequent basis to be there when you really need it. 73, Rick, KV9U Andy obrien wrote: NBEMS is the only application that would meet your DEC's requirements, find it within the latest implementing of FLDIGI.
