Hi,

Did you get the latest versions from Elecraft?
The programs posted here are probably out of date...

Hello,

Definitely a low current draw on receive. Now I would also add the 80m band as a requirement, or at least 40m, but 80m is better for NVIS. I am a big fan of CW for its efficiency and simplicity, but SSB is important too, and required for digital modes, though I am not a fan of digital, but it has its place.

Bottom line is, I don't think you can get away with only two radios... You would need an HF radio and a VHF/UHF one for local comms. Some do both, like the Ft-817/818nd but of course, you can only listen to either at the same time...

For me, I would have a small CW radio for bugging out, and a military SSB radio for bugging in or camp setup. UHF Handhelds for group members...

One important thing is to be able to listen to the broadcast news on HF (short-wave)...

Digital Modes / Off-Grid Crypto Transaction Primed for Post-Apocalypse.

Cryptocurrency and blockchain meet amateur radio. Not quite sure what to think of this one. I am always worried about the increasing level of complexity in disaster radio. It is nevertheless interesting to see new experiments involving radio.

Very interesting thanks. I didn't know about the man other than from his book.

Military Radios / Re: PRC-320 Military Manpack Radio, First Impressions.

Interesting thoughts, and I agree as well. For me, military radios are more on the hobby side than for prepping, but their ruggedness makes them a great choice for those situations when transporting them alone on foot isn't required. They are fairly cheap and will survive almost anything. Now, I would rather also have three or four (I have many more) $50-$100 radios than one or two $800 radios... It is also easier to scavenge parts for through-hole radios than surface-mount circuits. If one of my military radios craps out, no big deal, I have more... Sure, I'm not going to carry them all in a bug-out scenario, but they can be very handy.

I am reading a book by F. Spencer Chapman, "The Jungle is Neutral" (highly recommended), where enormous radio sets are carried by men on their back in the Malayan jungle and powered by pedal-driven dymanos... A PRC-320 compared to that is a pocket radio! These guys had virtually no support from the outside... So, all is relative... A group of determined men can accomplish miracles. Sure, we have better options today, and that even is debatable, but my PRC-320 with a hand-crank attachment can be a lifesaver.

Best solution? Have both, use what is most convenient or possible for the given circumstances...

I agree about everything you mentioned, except that I consider the 320 to be one of the easiest radio to use that I ever laid my hands on...

Antennas / Re: Best Antenna for MTB3

Hello,

Yes, the difference is the size. The 240-43 is a bit more efficient but much bigger. I use the 140-size. No tuner needed on 40/20m, maybe on 30.

For my MTR is use this to check SWR:

If the LED is not full-bright, you're ok.

Hello Guillermo, and welcome  :)

Get an FT-140-43 toroid core and a 100pf 3000V capacitor, some 1mm enameled magnet wire...
Use a 67ft antenna wire.

Then see the photos below:





The box above is a Hammond 1594B.

Thanks Ray. If only a handful of people pick up Morse from reading it, that would be great.
