Hello Folks,

A dilemma facing any newsletter or even a news group is that discussions often become narrower in focus as they progress. They appeal to fewer people, but for those interested, the level of interest can be more intense than ever.

So how does one maintain a workable balance without offending either the general audience, which is less interested, or the specialist audience, which is more interested than ever?

What's New? - from Dieter (DIZ) Gentzow - W8DIZ.

Every once in a while I find a real gem; just wanted to share the info.

This thing ROCKS!!! If you want a FREE software package that does what Microsoft's Office does, but is ULTRA clean, installs clean, imports and exports Microsoft Word and Excel, has tools for GIF and JPG and HTML, and much more, check it out.

The downloaded file was about 50 Meg, a lot less than u$. Oh, and this thing runs on Windows, and Linux. Did I mention Spell Checker, Thesausus.....?

[Ian's comments] - Owing to the extremely large size, I elected to buy mine on CD for the modest cost of about $US 10.00 (including tax, packaging and postage). Internet downloading would have taken me hours on dialup. I bought mine locally in Australia and there seem to be many sites world wide to buy the CD.

My CD arrived and comprised five files:

Ooo_inst.pdf - 509 kB. The 1.0 Setup Guide.
Ooo_font.pdf - 510 kB. Font problem trouble shooting. - 48.9 mB - 158 mB - 104 mB

According to The 1.0 Setup Guide:

General System Requirements
� 250 MB available hard-disk space
� Graphics capabilities of at least 800 x 600 resolution and 256 colors

Special System Requirements for Windows
� Windows 95 or higher. For the support of Asian languages,Windows 98 or higher is required.(Windows 2000 is recommended)
� PC with Pentium or compatible processor
� 64 MB RAM

For those people who may not know, "Homebrew" is DIY construction of equipment etc.

Back in April we had some discussion about the "Death of Homebrew" on the "Glowbugs List". This list essentially deals with valve operated equipment.

I was reminded of my original post today and decided it might well be interesting enough to convert it to a web page. Then again maybe not, you be the judge.

Here's the threat to owners of newsletters and news groups.

Here's the story from Symantic:
Removal tool, Symantec has provided a tool to remove infections of all known variants of W32.Klez and W32.ElKern. If your computer is detected as infected with W32.Klez.gen@mm, download and run the tool. In most cases, the tool will be able to remove the infection.[email protected]


Get your Club Project off the ground! Spread the word...

All I require is a plain vanilla text file (your-file.txt) of your written copy and, gif or jpg files of your schematics and photographs. Don't worry if you think your writing isn't terribly brilliant, that's what I'm for. Most times I need to edit work either for space, clarity or simply making it search engine friendly.

"Like every readout that preceded it, the liquid-crystal display had some severe drawbacks. The earliest digital displays were very crude, but when engineers wanted information as a number, as opposed to a needle position on a scale, they had to devise some way to display numeric digits. One of the earliest instrument displays, the columnar display, often called the thermometer readout, had columns of 10 holes punched in a front panel with a panel lamp behind each hole..."

From my old site, I have posted some addendums to this very popular page.

[A] 45-860MHz Radio receiver based on UV916-tuner

Just to give you some ideas to go on with. This site says:
"This receiver use a TV-tuner, a simple radio-circuit and a interface to a computer. The computer control (set) the receiving frequency from 45-860MHz The purpose of this project is to learn about tuners, it's a pre-project for my Spectrum analyzer project. The UV916 or UV918 tuner is easy to find in broken TV or VCR's".

[B] NASA's RADIO JOVE - Planetary Radio Astronomy for Schools

"Here in the Observatory's Electronics Lab you can learn about constructing receivers, antennas, and other useful equipment for Radio Jove's solar system radio astronomy observations".

(by ever popular demand) -


A baby turtle was standing at the bottom of a large tree and with a deep sigh, started to climb. About an hour later, he reached a very high branch and walked along to the end. He turned and spread all four flippers and launched himself off the branch.

On landing at the bottom in a pile of soft, dead leaves, he shook himself off, walked back to the bottom of the tree and with a sigh started to climb.

About an hour later, he again reached the very high branch, walked along, turned, spread his flippers and flung himself off the branch. Again, he landed on the bottom, shook himself off, went to the bottom of the tree, sighed and started climbing.

Watching these proceedings from the end of the branch were two little birds.

Mummy bird turned to Daddy bird and said, "Don't you think it's time we told him he was adopted?"

Zen Master

The Zen master steps up to the hot dog cart and says, "Make me one with everything."

The hot dog vendor fixes a hot dog and hands it to the Zen master, who pays with a $20 bill.

The hot dog vendor puts the bill in the cash drawer and closes the drawer.

"Where's my change?" asks the Zen master.

The hot dog vendor responds: "Change must come from within."
