Biking and Playing Radio (NEQP 2018)

On Sunday, May 6th, 2018 I rode my bicycle to a construction site with a good location for working portable. I set up my SOTABEAMS dipole and used my YouKits HB1B Mk III to make some contacts. The New England QSO Party event was being held that weekend and I worked 6 stations in a fairly short time.

It seemed like the sidetone of my HB1B devolved into lots of clicks and very little tone after a while. Not sure why but it was annoying. A great day for ham radio!

Easter Island on 5 Watts (from St. John USVI)

I’m on vacation for a couple of weeks. I brought my KX2 to the Caribbean and made this quick video to show you my contact with Easter Island. I also show you my setup – which includes an unusual antenna. I hope to make many more contacts, as time (and the wife) permits! – Cliff

For more info on the antenna… see Page 9 of this manual… http://www.elecraft.com/manual/E740054%20KXAT1%20man%20rev%20B.pdf

Bike. Radio. Japan!

I took my KX2 this morning when I went out to ride my bicycle. I found a good place to put up my dipole where I could be in the shade. After working 2 Japanese stations, I used my phone to record video of me working a third station so you can share in the joy of portable QRP.

Why not take your radio with you when you go out for a walk, a hike, bike riding, etc. You never know what will happen!

New England QSO Party – From Bobcat Ridge

This past weekend, I took the Mountain Topper radios (3B and 5B) to Bobcat Ridge and worked a bunch of stations.  In this video, I show my antenna setup and work 5 or 6 stations. At the end of the video, I show all of the stations I worked.

Not bad for 3 watts and a wire antenna.  I was only transmitting for about 90 minutes, total.  The various contests running this weekend made it super-easy to work QRP!

FIRST LOOK: MTR-5B (Mountain Topper 5-Band)

LNR Precision (www.LNRPrecision.com) recently released the first  production batch of their new Mountain Topper 5-Band QRP radio.

The MTR-5B is THE new pocket-sized QRP radio to have.  Highly Recommended!

As soon as I took it out of the box and hooked it up, my first contact was CN8KD in Morocco on 30m.  I take that as as good omen for all of the fun I will have with this amazing little rig.

In this video, I show you the improvements over the (still awesome) MTR-3B radio. I then hook it up to an antenna and take it for a spin, letting you see the new four-line LCD display and some of the many cool features.

 

Build a Computer to CW Interface

Using a  well-known circuit, I show you how to build a simple computer interface so  your logging software can send CW through your radio.

The logging software simulates someone using a straight key.  It changes the voltage on an RS-232 pin and the electronic circuit uses a transistor as a switch, grounding the lines as though someone grounded the contacts of a straight key.

This interface will let you work a contest or pile-up using your logging software – without having to use a key or paddle.
