A Small Notice to Blog Readers and Followers

For a month of more now, wordpress is getting an attack of fake accounts subscribing to blogs and spamming their comments.

All the fake accounts come from e-mail addresses.

Trying to battle this I think I may have deleted some real subscribers that use Microsoft Outlook.

I am very sorry for this. And I do not know of a way to re-list you myself.

I trust that you have found this blog of value enough, to go to the trouble to re-subscribe/follow.

Thank you!


Do NOT miss out on Bret’s SurvivalComms Youtube Channel

By a strike of luck the SurvivalComms name is used by me for this blog, and by another guy (Bret) for his YouTube channel.

It also happens that we both are focused on practical HAM radio matters for Survival and Prepping.

Bret is not only knowledgeable but also good at breaking down matters and applications  into simple, layman’s terms. Among these are his DIY simple antennas.

So DO subscribe to his channel.

Radio Communications Musings no1.

What is Communications?

The word has obviously has to do with “Community” in the sense of Sharing. Sharing of information that is. But what kind of information?

To put it straightforward, it is about information that will allow proper decision making on all levels of involved parties, and for the task at hand.

Imagine you are in a rescue team searching for an injured hiker. What kind of information would you beam back to base once you find him?The victim status is an obvious one. Time of arrival is another, needed resources and assistance on route is another, etc.

But does the base needs to know that you have arrived at a tight spot and you will have to rig a way to pass the stretcher along a crevice? So in the process you need to judge what to pass on and what to leave out. Cos too much of data may needlessly  burden and clog the command center, delaying decisions.

My Tupperware Baofeng Radio Kit

First I am cheap. Then I am unemployed. And lastly it is foolish to travel to the next big city to find a padded pelican case and pay for it as much as the kit costs, AND as much for gas money. So an old Tupperware brand food container was used. See, I do try for quality when I can!

So I started with placing a carton sheet on the bottom of the box, and continued by laying the items, and marking the dividers position. Then I removed the carton, made the dividers and glued them on. Then I proceeded with gluing thin packing foam sheet.

With a bit thicker packing foam I covered the bottom of the compartments and I also cut a covering sheet by the same material.

And I ended up with the following. Not pretty, but functional, and easy enough for your kid to do.
