ARRL report the National Institute of Standards and Technology (NIST) FY 2019 budget request includes shutting down “NIST radio stations in Colorado and Hawaii” — in other words, WWV and WWVH Continue reading
Good morning dear ARDF fellows,
South Africa’s SARL News report the ILLW takes place over the weekend of 18 and 19 August and, according to the entry list, Namibia has two lighthouses registered and South Africa has thirteen lighthouses registered for the event. Continue reading

On Sunday the 5th of August 2018, Mark Turner EI3KD managed to work D4Z on the Cape Verde Islands off the coast of of Africa on 144 MHz, a distance of some 4163 kms. This remarkable contact, made on CW, was a new record for tropo in IARU Region 1. The previous record of 4130 kms was set back in July of 2015. Continue reading
A Weekend Antenna Project
Joe N2CX had come up with an idea for a portable antenna for NPOTA use that covered the 40/30/20 m bands. This pairs nicely with the LNR MTR3B as well.
The QRP Guys worked with Joe to create a kit and a wind winder element to it.
Basically its a 1/4 wave on 20m with inductance being switched in as needed for the other 2 bands.
As per the QRP Guys manual https://qrpguys.com/wp-content/uploads/2018/05/tri-band_vertical_assy_042918.pdf I went ahead and an hour later I was ready for testing.
SWR on 20m is below 1.3, and the other bands are under 2 to 1 depending on the frequency.
A great piece of kit for the antenna box
The fiberglass rod is the chinese 7m fish pole that was $12 US
The Buddipole or (Buddistick) in a vertical orientation is simply a quarter-wave ground plane antenna. It is typically mounted on a tripod and mast about eight to twelve -feet off the ground. The elevated counterpoise runs at an angle to a counterpoise stick (driveway markers from the hardware store). The reason for the elevation of the counterpoise is to get the feed point impedance closer to 50 ohms and reduce the ground losses by a counterpoise laid on the ground. The trick then is to lengthen or shorten the counterpoise to get to resonance.
Don’t complicate it with 32 radials as I typically use one or two with great results.
Icom Inc. will be holding once again a D-STAR (Digital Amateur Radio) QSO Party this year. The global event will take place between September 22nd at 0.00 and September 24th at 24.00 (UTC).
The format of the party will be the same as in previous years with the goal of encouraging D-STAR operators to communicate with as many other operators across the world via D-STAR repeaters.
The prizes on offer this year have not been announced yet, so keep an eye out for the latest updates on the D-STAR QSO Party 2018 website www.icom.co.jp/world/dqp .
Entries for the 2018 International Lighthouse Lightship Weekend, ILLW, are on schedule with 250 being listed so far. Continue reading
With the resurgence of interest in the Magic Band, please print and refer to when listening.
Listening is not the right approach, call out on the assigned channels looking for activity or monitor beacons to check for activity.
DX Maps is also a useful tool
