ARRL Field Day 2014 announcement



Stay tuned for more updates...



- Public Announcement for immediate release -


The Arkansas Radio Emergency Services (A.R.E.S.) Club, The Central Arkansas UHF (CAUHF) Club and the Central Arkansas Veterans Healthcare System Ham Radio (CAVHS) Club have once again joined forces for this year's ARRL Amateur Radio Field Day @ the VA Hospital.



We three Little Rock Amateur Radio Clubs will once again be participating in the annual ARRL Field Day event the weekend of June 28-29 on the Historic Ft. Roots Parade Ground, Little Rock, Arkansas using the call sign N5AT.

We will be operating with emergency power and alternate power, erecting a 20m beam antenna, wire antennas and a magnetic loop antenna. There will again be a dedicated SSB station, a dedicated digital station, a digital&voice GOTA station and a VHF station. Digital operations will be CW (straight key) and sound card based modes, including Automatic Link Establishment (ALE AMD).


The AHDNN net will be conducted from this site between 1600h and 1700h CDT, 7.070 mhz 1000Hz +/-, MT63-500L.
Technician Class Licensees - SPECIAL NOTICE: Please check-in with CW on Center Frequency, we are listening out for you! Net will be conducted using the NBEMS software suite with FLDIGI and FLMSG to facilitate section "7.3.6. Message Handling” of the ARRL Field Day 2014 Rules. NBEMS nets in adjoining states have planned to stand by.


We have decided to organize the event per the NIMS / ICS model, as to increase our knowledge and experience with it, making use of and learning about the AUXFOG. We will have an Educational Activity and hope that the Little Rock Boy Scouts will be able to join us! http://fd.ema.arrl.org/FD_ICS.html

Irrespective of the above, our focus is - as always - on the great cameraderie between the clubs and it’s members, where everyone is invited and welcome to visit and operate.

Although we have chosen to follow the ARRL Field Day 2014 Rules Objective closely ("To work as many stations as possible on any and all amateur bands…” and to "developing skills to meet the challenges of emergency preparedness as well as to acquaint the general public with the capabilities of Amateur Radio.”), we will nonetheless approach it as we always have, with a degree of leisure appropriate for the searing heat at that time of year!

If you have time, come join us!


Directions to the park are here: Google Maps directions and please see the map at the bottom of this post, we will be located on the Parade Ground.

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).

Portable solar-, hand-crank, wind-, water-power in a backpack size...

...sound too good to be true? You might be in for a surprise!

If you go RaDAR, you owe it to yourself to...

Go here:
and also see this:

I have searched around and have run trials with various equipment for some time now, solar panels, various hand cranks, charge controllers, but have not found anything which is as all inclusive as this promises to be and most importantly - actually working. I look forward to the product launch and more detailed specifications scheduled for May 2014.
