I have my ten element 2m antenna vertically polarized mainly for repeater op. Was wondering how other ops place their 2m beams.

Traditionally it is vertical polarization for FM and horizontal for SSB
and CW. Kevin. KD5ONS On 6/20/2013 5:46 PM, Harlan wrote: > I have my ten element 2m antenna vertically polarized mainly for repeater op.

I keep my 13 element 2m beam horizontal for SSB work. I have some kind
of pulsating interference from an unknown source in the FM portion of the band for it to be of much use.

I have mine horizontally oriented for SSB and CW. It's an old 10-element beam and seems to do OK for FM repeater use as well.

Aren't many repeaters collocated with other commercial equipment on those giant (1500') broadcast towers we see all over the plains? My ham buddies in NE Iowa tell me this is generally the best anyone can do, even if it costs a bit.

I just made a round-trip from Florida to Montana in the past two weeks,
scanning the 2M and 70CM simplex channels and repeaters along the way. In 6 days on the road I heard exactly one conversation. And it was on 146.520 between two 18 wheeler hams on I-90 in South Dakota.

When you travel our direction (winter time for you snowbirds) you are invited to utilize a very active 2-Meter repeater system known as the EAARS Network.
Go to http://www.eaars.com/eaarsnetwork.html for information and map locations of the various nodes. 2 Meters is very alive and well in the southwest US. Also see http://nm5ml.com/ for total New Mexico coverage. Good luck in your travels. de Milt, N5IA -----Original Message----- From: Larry Ewan Sent: Friday, June 21, 2013 8:01 AM To: [hidden email] Subject: Re: [Elecraft] OT: 2m beam orientation I just made a round-trip from Florida to Montana in the past two weeks, scanning the 2M and 70CM simplex channels and repeaters along the way.

I use a small yagi vertical (13B2) for one of my FM antennas for a while.
With it @ 65' and 50w could work repeaters as far as 170 miles away most of the time. Using a good preamp and 165w about 225 mi or so. -----Original Message----- From: [hidden email] [mailto:[hidden email]] On Behalf Of Richard Fjeld Sent: Friday, June 21, 2013 9:35 AM To: Ron D'Eau Claire; [hidden email] Subject: Re: [Elecraft] OT: 2m beam orientation Here in the plains the closest thing to a mountain top is a gopher mound.

> ....repeater activity is almost dead... ============== There are about 30 repeaters audible from my QTH, some on 2M and some on 440. My 2M/440 radio is turned on and scanning them much of the time. Some days I hear no conversations. There are some weekly nets, and a sometimes a few commute-time chats. But VHF/UHF activity here in St. Louis County seems to be a fraction of what it was 40 years ago, even though I think there may be more repeaters today. Some of the repeaters are rigged to hook into the global linking system so that somebody here can work somebody, for example, in Australia via local repeaters. I've heard that used only a couple of times. Our DX club has a calling frequency that in days past was frequently occupied with tip-offs, DX chat, and general ragchewing, but even that has fizzled down to almost nothing.

I think that's true in many places, Dick.
Ten years ago, there were some repeaters here in the greater LA area that were hopping 24/7. Now, with many of them...silence. I have no idea what caused the change. 73 de Jim - AD6CW On 6/21/2013 7:35 AM, Richard Fjeld wrote: > Here in the plains the closest thing to a mountain top is a gopher mound. > > Seriously though, repeater activity is almost dead compared to what it once was. > > Dick, n0ce > > ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[hidden email] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html |

Somewhere back in the 80's [or so, memory fails me these days], I got
several of the IEEE group Proceedings, among which were Info Theory and Vehicular Technology [my employer was doing a lot of the latter which involved me in a lot of the former]. I read one paper, from Japan I think, about this idea of having very low power radio sites that "portable" phones could talk to, and a computer control system to manage the hand-off to other sites as the caller moved. I said to my cube-mate, "Have you seen this?", and he said, "Yes, what do you think about it?" I replied, "That'll never work, and besides, who would want to carry one of those phone bags around with them everywhere?" That's my answer to Jim's question. I also read about this US DoD program to put multiple satellites in orbit to allow ground devices to determine their position. I figured, "DoD? This will be a huge boondoggle." LORAN-C is now defunct. Being in the comm/computer/defense biz, my wife asked me if we wanted to sign up for this thing called an Automated Teller Machine card at Wells Fargo. I suggested we not bother, just one more card, "Believe me, this isn't going to catch on, who wants a machine giving them their own money?" The only time I've been an early adopter is with Elecraft [K3 #642], and not even then all the time [K2 #4398]. And "computing in a cloud" really sounds like Star Wars although my Kindle Fire at least thinks it has it's own cloud. 73, Fred K6DGW - Northern California Contest Club - CU in the 2013 Cal QSO Party 5-6 Oct 2013 - www.cqp.org On 6/21/2013 4:05 PM, Jim Lowman wrote: > I have no idea what caused the change. ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[hidden email] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html |

Wow! AT&T had cellular service (AMPS) under development in 1979 and put the first system on the air in 1983. What was the novelty that it had to be written up in IEEE-VTS (I was a chapter chair of VTS in that era)? Was it that the Japanese also had it under development in that same time frame? 73 de K2ASP - Phil Kane Elecraft K2/100 s/n 5402 Life Senior Member - IEEE From a Clearing in the Silicon Forest Beaverton (Washington County) Oregon ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[hidden email] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html |

Not quite. Dumb terminals were dumb. Rich web applications place a lot
of the user interface rendering onto the client. Not at all like dumb terminals. The "Cloud" is a bit more complex than what an old mainframe did. And we are only scratching the surface. Better to think of cloud computing as distributed computing. Properly done, its hard to tell where the client stops and the server begins. And that would be the point. 73, Doug -- K0DXV On 6/21/2013 9:08 PM, Phil Kane wrote: > On 6/21/2013 5:23 PM, Fred Jensen wrote: > >> And "computing in a cloud" really sounds like Star Wars although my >> Kindle Fire at least thinks it has it's own cloud. > "Computing in a cloud" is nothing more than an updated version of > mainframe-and-terminals from back in the 60s.

Phil,
IMHO, that is a wise decision. While "the cloud" is supposed to be secure, I have my doubts. The only thing I would consider committing to the cloud would possibly be encrypted off-site backup data, but for now, my RAID file server serves that purpose quite nicely, although it does not offer me off-site backup storage in case of a major disaster. I can write my backup data periodically to DVDs and keep them at a different location should I deem that necessary. I do not have anything that is classified, so am most concerned about data recovery in case a disaster totally destroys the drives on my file server. 73, Don W3FPR On 6/22/2013 11:47 PM, Phil Kane wrote: > Our servers are our property and under our control.
