Tactical Corner / Re: Nuclear War Survival — How To Survive a Nuclear War
« Last post by CPR on June 21, 2018, 09:56:59 AM »
Well I saw the video.. It looks like a toaster or oldschool radio. If you got that used I should get some radioactive testing probes to check the geigermuller tube if its still working.
You can try to convert röntgen to sieverts using this: https://www.unitjuggler.com/equivalentdose-umwandeln-von-rem-nach-Sv.html
0.5 Röntgen is 5 mili Sieverts. Thats pretty high. I am not sure if the unit you have shows those readings in unit per hour or what?

What do you think of this one:

Reviving an old topic...
I got myself a TerraP+ geiger counter. They seem to be pretty good, in Ukraine and Japan they are beeing used a lot. I live near a nuclear power plant (30km), so that's a wise investment IMO. Once or twice a week I measure the gamma dose. Actually I made a video once about radiation 101, trying to solve some mysteries about it:

Anyway, I dont think TEOTWAWKI will ever happen. The government will establish law sooner or later. IMO prepping is just about to fill the time gap of lawlessness until it is functioning again.

You defiantly will not regret learning morse code. It’s not like buying a computer interface to run FT8 and after a few contacts getting bored of it and regretting the purchase. Learning morse code is a lot more rewarding and even if you eventually bore of it, it will always be useful. It’s not a product, it’s a skill.

I agree that digital modes like FT8 have limited usefulness to the preppers but that’s not their target users. On the other hand, FSQ was designed specifically for emergency comms. Modes like FSQ and Olivia are very handy to the emergency communicator. FSQ can even send messages while the receiving station doesn’t have an operator present at the radio.  They perform better than CW. They can send faster and in worse conditions. Their only downside is that they require a computer. This adds weight, complexity, points of failure, and power requirements. If you can afford the additional weight and power requirements they are a good way to go.

I have an IC-706 in my suburban and am setting up a mobile station that can run digital on all HF bands. This mobile station will be able to run digital modes for extended periods of time until I run out of gas. Then the foldable 22 watt panel will allow me to run the station for short intervals.

This thread got me thinking though, when was the last time I even heard a QRP station?
Do you do much CW? I’m in the El Paso area and I have regular QSOs with QRPers on CW. I’d estimate that ¼ - ⅓ of my CW QSOs are with someone running QRP.

I was referring to QRP on SSB, I don't do any CW yet but it is on my serious to do list this coming off season (HVAC Contractor).  I will probably go ahead and get MRP40 just to play around until I can become proficient with CW.  The digital modes such as FT-8 are neat for testing antennas but I really don't see them being useful as much as CW in SHTF.

I still need a wolphilink for my 817, but yes, thats a good idea for a comparison!

Sotabeams makes some good stuff. That looks like a nice balun. If you can set up a wispr beacon it might be a good way of doing direct comparisons of the antennas.

Antennas / Linked Dipole
« Last post by CPR on June 20, 2018, 08:29:30 AM »
For quite a time I was interested in building a resonant multiband dipole or linked dipole.
I see a lot of benefits in it, especially no tuner is needed therefore no loss for qrp. Although you have to carry a bit more of equipment, the linked dipole should perform the best regarding noise and stuff - so they say.

Anyway, I got myself the dipole center with a 1:1 balun kit from sota beams.
I found a great tutorial on how to trim the wire :

http://amateurham.co/4-band-linked-dipole-how-to/

So in the following days I intend to build the linked dipole and will keep you updated.
I'm quite curious about the performance compared to the random wire end fed antenna. I intend to use this linked dipole with my 6 meter telescope pole.

I seriously doubt I will be running around performing comms ops like some guys plan.  More than likely it will be if and when its time to move to a new location.

Running high power rigs in the air in SHTF is like drawing a target on your back. Also you need to change locations often or your shack will become a target.
In the civil war in Yugoslawia, HAM operators had an important role in relaying information to the army as the Croatian army and informational infrastructure was not present / cut off. Resulting in pinpointed attacks from the aggressor on villages with active ham operators. Just sayin. If they saw an antenna on your roof, your house was gone.
