Out portable on the Lincolnshire Wolds
Following a recent presentation at the South Kesteven ARS by David Gordon G6ENN where he talked about his successful portable operating I was encouraged to constructed a simple dual band 'flower pot' antenna (design from VK2ZOI) using some RG58 coax and 25mm conduit.

My previous attempts at portable operating have largely involved HF and slightly heavy equipment (my Yaesu FT-857D and Sealed Lead Acid batteries) but I decided this time to try VHF/UHF as we were going to one of the highest spots in the area. This allowed me to travel light just taking along a Baofeng UV-5R and the antenna sticking out of the rucksack.
Just setting off with Boris & Eddie |
Parking up in Donington on Bain we had a short 4 mile circular walk planned allowing the wife to collect a dozen geocaches along the way with a short detour at the top to visit RAF Stenigot. The walk climbs to the top of a hill, but it isn't a long ascent by any means or overly strenuous. The view back included the impressive Belmont Transmission Tower (just visible over my shoulder in the picture above) which before it was shortened in 2010 was reputably the tallest structure of its type in the world.

The Lincolnshire Wolds is the highest area on the East of England between Yorkshire and Kent and so there are many structures that take advantage of the elevation. In addition to Belmont we could see the Radar station at Wolds Top/Normanby Hill and Lincoln Cathedral in the distance, but we were interested in what was in front of us the remains of RAF Stenigot.

View back |
After the Second World War, the site was retained and in 1959 it was upgraded to a communications relay site as part of the NATO ACE High system, which involved adding four tropospheric scatter dishes. The site was decommissioned in the late 1980s and was mostly demolished by 1996 but the toppled dishes remain.

What's more you aren't far from the Lincolnshire Coast, so after our walk we went to Mablethorpe for the afternoon and fish and chips which were well received.

Amateur radio below 9kHz
Until a few years ago, the conventional wisdom was that you needed huge power and huge antennas to be copied “beyond the garden fence” at VLF and ULF. In recent years much has changed and time and again great distances have been covered by amateurs with quite low power and modest antennas.
The trick is great stability, very narrow bandwidths and long integration times, often of days. For several years just detecting a carrier was enough, but in recent times people have been sending simple messages using EbNaut software.
When at the old QTH I detected signals from several European countries using simple, homemade gear and free software.
Although not totally up to date at all times, I try to update news of amateur VLF and ULF experiments at https://sites.google.com/site/sub9khz/ .
Simple yagi for wi-fi router
This was first seen some weeks ago and I saw it earlier today in an email from Twitter. It shows you how to make a simple add-on yagi for your wi-fi router.
In my case I get sufficient range with the router “as is”. You might find it useful if you need to increase the range in a certain direction. It is a simple idea, which I like.

To help with your NPOTA withdrawal
POTA is the United States arm of WWFF and POTA encompasses not only NPOTA, but State Parks as well. So if NPOTA was difficult for you as an activator, POTA should be easier as it will include many places that were not part of POTA.
Take for instance, the Great Swamp Wildlife Refuge (KFF-0454) here in NJ. I drive through it every time I go up to HP28, Morristown National Historical Park (KFF-0746), which is part of NPOTA. Since the Refuge is administered by the US Fish and Wildlife Service, it was not part of NPOTA - but it IS part of POTA. My favorite portable operating spot, Washington Rock State Park, is also part of POTA (KFF-1635).
Activation requirements for WWFF are a bit stricter. For a valid activation, WWFF requires 44 QSOs, while NPOTA required only 10. Happily, according to my good friend Greg N4KGL, POTA also requires only 10 QSOs for a valid activation. A good day's worth of portable operations should cover you. If you're bound and determined to work towards Activator awards, then you have a good program here to fill your heart's desire.. Me? I'll just be happy to have the "excuse" to go out and put some NJ parks on the air.
I've only just registered and have not looked into all the details about how to upload logs and stuff; but I am bound and determined to put some parks in New Jersey on the air this coming Spring and Summer for the chasers that are really into this.
