Portable hand-crank power in a backpack size...

I have previously posted about an upcoming 12V portable hand crank electricity generator for the commercial market. Here I will report about a Mil-Spec portable hand crank generator that might just be the solution for you.

Sometime back I ordered a Clansman Hand Generator (please perform internet search on these as I do not want to bias you on whom to order it from). It generates 24 Volt DC (open voltage) at moderate speed cranking and a maximum of 30V (open voltage) when cranking at the maximal speed  that I can still manage relatively comfortably. Please see YouTube videos for further details on this crank generator.

So how could you use these 24V to charge a portable battery? Just connect two small 12V batteries in series... and you have a heavy duty (yes - that does also imply fairly heavy weight).

2014 ARRL Field Day - NTS-style message Bonus

ARRL HQ replied today regarding my inquiry about further details on the 2014 ARRL Field Day "NTS-style message Bonus".

It is the message format which is of interest and not the message carrier, i.e. as long as it is in proper NTS radiogram format & via RF. Quote:

"Yes, messages sent via NBEMS or Winlink will count for Field Day bonus points as long as the messages are in the proper NTS radiogram format and the messages leave or enter the Field Day site via amateur radio RF."

That will be most exiting! I can think of: voice (ok, that's nothing new), CW (this neither), FLMSG (within NBEMS suite of free software programs), WinLink, HFLink ALE AMD and APRS as being possible carriers of the radiogram, with the last two likely the least common choices for most HAMs. Maybe I can think of a few more by Field Day… Why don't you too bring something new into YOUR Field Day activation, with some new modes of message relay?

Thus, the Arkansas HF Digital NVIS NBEMS Net (AHDNN) will be operational and have extended operational hours during Field Day, schedule to be announced on the AHDNN newsgroup, NCS: N5AT.

Additionally, the Arkansas Radio Emergency Services Club will send NTS radiograms via all above mentioned digital modes of communication.
