I have a radio. No clue how to use it. What's the best option for recharging it? [/quote] I would learn how to use it, and then set up the following: A galvanized garbage can to store it in. Galvanized lid, too. A cheap used laptop ($100) with MuliPSK or Hellschreiber software A 150 watt inverter and computer / radio power supplies A 10 watt solar panel with charge controller A 12 vdc deep cycle battery (doesn't need to be in the can) An antenna for the radio. Once you have all this together and prove it works with Hellschreiber, put everything minus the battery in the can. Seal the can with aluminum tape. Keep the battery on a trickle charger. The 10 watt solar panel should give you four hours of daily operation. A 60 - 80 watt panel should give you 24 hours a day use reliably. Don't know if a panel that large can be put in the can, which it needs to be for EMP.

Only thing on a panel is blocking diodes right? [/quote]

The question that has been kicked around on various threads is what if the GLP effect fails? How do we get the juicy info if it all goes sideways?
One way to do this is with HF radio on the 20 meter band using 50 watts, using a text mode called Hellschreiber - also called Feld-Hell.
Here's an introduction to this mode:

The idea would be to have a master station receiving at 20 meters throughout the day. 8 am CST to 7 pm seems to be the best for radio propagation at this frequency.
PRIMARY: 14.064 Mhz
SECONDARY: 14.075 Mhz
TERTIARY: 14.077 Mhz

Every day, say at 5 pm CST, a digest of all the field reports received with Feld-Hell would be retransmitted several times via CW. Then the master station goes into receive mode.
You wouldn't need a transmitter to get these reports. A HF receiver like a Grundig could receive the transmission, and a laptop with free Hellscheiber decoding software would display the daily digest.
You can download the software here:

And radio-computer hookup information is here:

Alternatively, a computer with an external microphone could conceivably receive the transmission by simply putting the microphone near the radio's speaker - no splicing wires would be needed.
