EI3KD works Cape Verde Islands on 144 MHz to set new DX record

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

QRP Guys Portable Tri-Band Vertical Antenna 40-30-20m

A Weekend Antenna Project

ve3ips

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

Buddipole Design and Tuning

ve3ips

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.

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

50.06-50.09 Beacons
50.0-50.1 CW
50.090 CW Calling Frequency
50.06 QRP CW Calling Frequency
50.7 RTTY Calling Frequency
50.100 to 50.130 DX Window (USB)
50.110 DX Calling Frequency (USB)
50.115 DXpeditions
50.125 USA National SSB Simplex Frequency (USB)
50.1-50.6 Weak Signal, AM
50.260 is the WSJT Meteor Scatter
50.270 FSK Meteor Scatter
50.300 FM Simplex Calling Frequency (West Coast)
50.385 USB PSK31
50.4 National AM Simplex Frequency
50.885 QRP SSB Calling Freq

Upcoming ARDF Events

Happy longest day of the year and start of the Summer!
Important dates coming up for the ARDF (please check website for more details www.ardf.ca):
 
Jun-23 -> ARDF 80m demo at  SARC Field Day 
Jul-7 -> Practice ARDF foxhunt 80m
Aug -> Visit and ARDF fox-hunt in Victoria (TBD)
   Our annual traditional event with friends from Victoria. Last years event was sprint ARDF with 12 transmitters hidden and on 12sec transmitting cycle, hence as sprint name.
 
Sept -> Abbotsford ARDF fox-hunt (TBD)
   We would like to have another event in this area to popularize the sport.
 
Should you have any questions, ideas, suggestions, etc, please contact us.
