NVIS Research Paper Available

Many Amateurs experiment with, or use on a daily basis, NVIS (Near Vertical Incidence Skywave) Antennas. The ARRL published info and a link about this on Thursday. This paper is open to any with the link – you do not need to be an ARRL Member to access it. This is an in-depth scholarly article, but do NOT let that turn you aside. There is much to be learned here.

[NOTE: At Press Time the link to the paper in the original ARRL article was bad, however I have corrected it the excerpt below]

A thorough and fully annotated discussion of Near Vertical Incidence Skywave (NVIS) is available in the research paper, “Radio Communication via Near Vertical Incidence Skywave Propagation: An Overview,” by Ben A. Witvliet, PE5B/5R8DS, and Rosa Ma Alsina-Pagès.

First investigated in the 1920s, NVIS propagation was rediscovered during World War II as “an essential means to establish communications in large war zones such as the D-Day invasion in Normandy,” the paper notes, adding that the US Army subsequently sponsored a lot of NVIS field research, especially between 1966 and 1973. More recently, NVIS has become a popular means to enable close-in communication on Amateur Radio HF bands between 3 and 10 MHZ. NVIS can be used for radio communication in a large area (200-kilometer radius) without any intermediate manmade infrastructure, and it has been found to be especially suited for disaster relief communication, among other applications, according to the paper.

ARRL Incoming QSL Bureau

Everything, and I mean EVERYTHING that you could ever want to know about getting real live QSL cards into your hot little hands can be found right there. If it ain’t here, you don’t need to know about it!

[Excerpt]

The ARRL W5 Incoming QSL bureau is operated by the Oklahoma DX Association. The bureau consist of volunteers who provide this valuable service to their fellow hams. Cards arrive at our P.O. Box from various sources, such as other DX bureaus around the world and the ARRL Incoming Bureau. Upon arrival, the cards are presorted by a group of volunteers. This presorting consists of grouping the cards alphabetically by the first letter of the call suffix, for example, W5ABC, WB5AFG, N5AA would all go in the same “A” stack. The presorters then return the sorted cards to the bureau manager. Each letter of the alphabet has another sorter assigned to handle the actual mailing of QSLs and notices when a ham has cards on file but no envelopes or credits. Every two months, the cards accumulated for each letter of the alphabet are mailed to the sorters. Each letter sorter is then responsible for matching up the cards with envelopes and mailing when enough cards are accumulated to cover the amount of postage provided. They also notify any ham who has cards on file but no envelopes. Please check the Procedures and Dos & Don’ts links for details on proper procedures for using the W5 QSL Bureau.

Upright “V” Dipole

This is topical (for me at least) this week…

[Excerpt]

The concrete lanai of a condo is about as bad, technically, as it gets for limited space antennas.
In addition, there are usually house rules and condo bylaws.
However, there should be some provision for antennas.
Most condos have had to contend with the direct TV satellite dishes and the rules for those should also cover Ham antennas.
There may be restrictions on things like visual impact and especially attachment to common areas.

Read it all here: http://www.chem.hawaii.edu/uham/vee.html


$4 Satellite Antenna

Simple, inexpensive and lots of fun!
Here is an easy to make home brew antenna that can get you on the air working satellites or be built for use as a portable hand held antenna to extend the range of your HT.

It’s a dual band 2m/70 cm yagi antenna made with common materials and cost very little to make. Also, the antenna is fed with only one coaxial cable and does not use a duplexer.

Worldwide YL DMR Talkgroup

When Gary asked me to write about the WWYL Talk Group 955, the first thing that came to my head was, an old Connie Francis song that as a kid, I used to change the words.  From “where the boys are”, to “where the girls are”!!

 I am just now setting up my DMR radio. So expert, I am not (yet).  However, a very nice YL, Dvora, (4X4NW) from Israel, is helping me.

 So what is Talk Group 955:  just a bunch of YL’s, or it will be as soon as we can get the word out!  We do not have any specific nets set up yet.  As soon as we get this organized, we will and I will let everyone know!

 How do you get to the talk group?  All the info is published in http://w5nor.org/okdmr/. In order to add the talk group details (transceiver dependable), you should refer to the codeplug page http://w5nor/codeplugs/index.html). Just remember, Worldwide Young Ladies talk group, WWYL is TG 955. The Code Color (CC) is 1, and the Time Slot (TS) should be set to 2.

 You can listen to the recorded archives here: http://hose.brandmeister.network/955/

BTW there is a talk group set up for JOTA #907!

 Collector & Emitter

Here is the direct link to the historical issues of CORA’s almost 30 year long, monthly publication, The Collector & Emitter. Lot’s of great stories, True and Fiction, MANY club meeting notes, Happenings in Oklahoma Amateur Radio, and for me at least, a ton of memories about the Amateur Radio Dealers which we had in the OKC area. Lots and lots of fun reading.

When you start reading these, the clock will just melt away…
