[digitalradio] Final goodbye for early web icon
Not a ham radio related topic but I thought I would share this, I am sure some hams used this. Final goodbye for early web icon By Jonathan Fildes Science and technology reporter, BBC News Netscape's demise A web browser that gave many people their first experience of the web is about to disappear. Netscape Navigator, now owned by AOL, will no longer be supported after 1 March 2008, the company has said. In the mid-1990s, as the commercial web began to take off, the browser was used by more than 90% of people online. Its market share has since slipped to just 0.6% as other browsers such as Microsoft' Internet Explorer (IE) and Firefox have eroded its user base. The company recommends that users upgrade their browser to either Firefox or Flock, which are both built on the same underlying technologies as Navigator. I think we represent the hope that was of Netscape, Mitchell Baker, chair of the Mozilla Foundation which coordinates development of Firefox, told BBC News. We have picked up many of the things that Netscape launched but we've taken them further in terms of openness and public participation. Ms Baker was one of the first employees at Netscape in 1994. Web window Netscape was created by Marc Andreessen who as a student had co-authored Mosaic, the first popular web browser. Firefox logo Firefox uses the same technology as Navigator developers His company Netscape Communications Corporation released the first version in 1994. According to Shawn Hardin, President and CEO of Flock, Netscape played an important role in making the internet a relevant mass market phenomenon. Netscape had a critical role in taking all of these zeros and ones - this very academic and technical environment - and giving it a graphical user interface where an average person could come online and consume information, he told BBC News. During its halcyon days¿it really felt like the internet and Netscape were really the same thing, he said. Other companies capitalised on Netscape's success, notably Microsoft, which began to bundle IE with its Windows operating systems. Netscape is a wonderful browser, and it will be so in the future Comment on Netscape blog Although this lead to legal wrangles over anti-competitive behaviour, IE now dominates the browser landscape with an 80% market share. As a result, Netscape became unviable. While internal groups within AOL have invested a great deal of time and energy in attempting to revive Netscape Navigator, these efforts have not been successful in gaining market share from Microsoft's Internet Explorer, said Tom Drapeau on the Netscape blog last year, when the demise of the browser was first announced. Future return? For the past week Netscape users have been shown a message alerting them to the end of support for the browser. Given AOL's current business focus, support for Netscape browsers will be discontinued as of March 1st, 2008, the message reads. flock logo Flock is designed to take advantage of web 2.0 sites It then suggests users upgrade to either Flock or Firefox. Firefox is the main competitor to IE, particularly in Europe where it has a 28% market share, according to some statistics. The open source browser's development is coordinated by the Mozilla foundation, set up by Netscape staff made redundant in 2003. It has had more than 500 million downloads worldwide and in countries such as Finland it is the most popular browser. Competition is what brings quality, said Ms Baker. Flock describes itself as the social web browser and allows people to see feeds from community websites, such as Flickr and Facebook, and post to blogs without having to navigate to the page. There are lots of ways that people are engaging in having a conversation and Flock is very focused on making that as effortless and convenient as possible, said Mr Hardin. However, not all Netscape users are happy about having to change browser. I'm sad. Flock still needs improvement and I am not happy with Firefox's interface. I'm [an] orphan! read one post on the Netscape blog. Others who posted comments on the blog predicted the browser will make a return. Netscape is a wonderful browser, and it will be so in the future, read one. -- Andy K3UK www.obriensweb.com (QSL via N2RJ)

Re: [digitalradio] Some thoughts on antenna polarizati on for emergency use
For a 20 Mile path to the server I use 28 MHz ground wave, works with 5 Watts pskmail day and night. That is with PSK 250. The server has a horizontal dipole on the roof of a 65 meters high building. When I am at our contest location in Germany, 100 Miles away, I use 80 meters NVIS with 80 Watts from the camper to my home with a horizontal linear loaded antenna. Also with PSK250. Difficult during the night because of high qrm levels. 73, Rein EA/PA0R/P -via pskmail server PI4TUE - -Ursprüngliche Nachricht- Von: digitalradio@yahoogroups.com Gesendet: 29.02.08 16:30:39 An: digitalradio@yahoogroups.com Betreff: Re: [digitalradio] Some thoughts on antenna polarization for emergency use Thanks for the comments, Ralph, Most of us OT's have known about the cross polarization for decades. But it really does hit home when you try it out for yourself. I had never had both horizontal and vertical antennas available to me at one time as I only had horizontal back in 1964 when I was first on 2 meter AM. Later on I only had vertical. I spent some time searching the web for some solid information on the distance issue. Some practical numbers perhaps? There just does not seem to be that much advantage to horizontal the closer the stations are to each other. Some difference on the over 100 mile paths perhaps, but I wonder how often we will use that long a path on VHF for this kind of work. My recent SSB contact to north of Chicago to a high end weak signal operator to my 50 watts with a 4 element beam at a very good location tells me that this 180 mile path might have even been difficult for digital modes. Lots of very warbly audio and severe QSB making phone contact barely possible. But it would have been most interesting to try digital on that path to get a feel for it. For digital modes I can operate 160 meters up thru 6 meters, but not 2 meters at this time. Perhaps some of you have tried calling CQ on PSK31 or other modes on say, 6 meters? I have done this many times on 50.290, but no luck and have never heard anything either. I have heard some PSK31 on 28.120 but nothing local as it was likely all Es. Using repeaters is absolutely not an option since we are specifically trying to operate without infrastructure and if the repeaters are operational, other communications are likely to be operational as well in an emergency situation that we are preparing for. And with our terrain, 20 miles on VHF FM through a repeater, can be difficult. Our repeater drops out in several directions when you approach that point when operating mobile, even though the repeater location is on a high water tower at about the highest point in the county. We will find out a lot more this spring/summer when we do the 2 meter SSB tests and find out for myself. Maybe I can convince someone to operate VHF digital? We hope to do something with 6 meters too, but Skip recommends 2 meter SSB equipment for NBEMS digital. We will also be trying several HF antennas to compare portable operation. We have mobile HF operation with my wife's vehicle, but you lose ground wave on 75 meters within 10 to 15 miles. Since there is minimal NVIS pattern from a vertical HF antenna, mobile operation does have its downsides for close in work. Much of what hams think is ground wave on HF, can be NVIS. If the FoF2 drops down to 2 MHz at night, I have found it impossible to try and communicate on 80 meters with a station only 20 miles away. And that is using CW! To give you an idea of the problem that an ARES ham faced this summer during the 1000 year flood, he was stationed at a remote location that was well out of range of the repeater. I just measured the distance and it is only like 15 to 18 miles and yet he had no way to hit the repeater from that location, even though he had a very good portable setup. The only way he could contact the DEC to coordinate ARESMAT help was with cellphone. He later admitted that this was a ridiculous situation. I pointed out that if he is serious about an amateur radio solution, he, and others in ARES/RACES, really need to give consideration to getting their General class license and having HF capability and have the equipment and know how to use it. The only other possibility that I can think of is 2 meter SSB phone/digital, but as I have said, no one has tested the efficacy as yet. In terms of the EOC, we have had several Field Day activities at the site and we tried to set up an 80 meter dipole but the building really does not fit that kind of antenna very well and is festooned with many other antennas that we don't want to interfere with. So if we absolutely must set up HF at that location, we can quickly install a sloper dipole. Not pretty as you point out, but will work. An alternative would be to have a VHF ink to a home station that has emergency power. Or
Re: [digitalradio] Some thoughts on antenna polarization for emergency use
Hi Ted, That's a good thought, but the problem is that achieving more than a 16 to 25 mile range without a repeater requires more gain (on at least one end - usually the home station end) than you can get from a lindenblad antenna, a big wheel, a ground plane, or even a 5/8 wavelength vertical. The portable end will also generally be at a lower elevation than the home stations. According to Cebik (http://www.cebik.com/ao/ao16a.html), the Lindenblad antenna has about 6 dBi of gain, and the big wheel about 7 dBi. Those antennas will work at the portable end, but on the home station end, more antenna gain (approximately 10 dBi or greater) is needed to ensure spanning a wide disaster area up to 100 miles without a repeater. For exceeding the distant obtainable by repeaters, which are usually positioned as high as possible, and usually higher than the typical home station antenna, even 3 dB of extra gain can make the difference between 100% copy and no copy. The Lindenblad is most useful for satellite work, where it can accomodate circular polarization and a high angle of reception. For operators already using repeaters with FM-only transceivers, the move to SSB is the major change (i.e., a new transceiver!), and the antenna change to horizontal polarization is relatively minor. In many cases, where 5-element vertically polarized beams are being used to hit repeaters, it only involves fliping the beam 90 degrees. In fact, any such beam can also just be rotated 45 degrees and handle both vertical and horizontal polarizations, but with a 3 dB loss in gain for each polarization. There is a whole new world of fun available on 2m SSB and digital that those who only work VHF via repeaters are missing. Instead of collecting countries, VHF SSB stations collect grid squares, counties, and states, so there is quite a reward to be had for joining the horizontally-polarized VHF world on 2m as well as being ready to assist with emcomm. 2m SSB is not all weak signal operating. Using my 13 element 2m beam, I have consistently worked horizontally-polarized mobiles over distances just exceeding 100 miles, when the elevations of both myself and the mobile do not exceed 30 feet ASL. 73, Skip KH6TY - Original Message - From: Theodore A. Antanaitis To: digitalradio@yahoogroups.com Sent: Friday, February 29, 2008 4:16 PM Subject: Re: [digitalradio] Some thoughts on antenna polarization for emergency use How about the best of both worlds (or at least an approximation thereof). I would suggest for two meter home station applications that a lindenblad antenna is a versatile compromise omni-directional antenna that works equally well with both vertical and horizontal polarizations. The complexity of construction is not that much greater than for a big-wheel or three dipole array.
