Using a 5W Linear Amplifier with a 200mW WSPR Beacon
Testing Three Antennas Simultaneously using WSPR with WSPRlite
QRP-labs.com offer a range of cost effective electronics kits for radio hams. I chose to order and build their 20W Dummy Load kit.
The kit is simple to build, consisting of x20 1KΩ 1W resistors sandwiched between two PCBs with a BNC connector. There is also a diode/capacitor circuit for detecting the peak voltage, if required.
Following my purchase of the Sotabeams WSPRlite WSPR beacon a few weeks ago I have just built the optional Low Pass Filter (LPF) kit for operation on 40/80/160m which I will primarily use for 40m. You can see my review of the WSPRlite unit on our club’s website.
K1JT’s superb WSPR protocol has kept me busy/addicted for months, but until recently I was RX only, relying on the global network of other Ham’s WSPR transmitters so that I could spot and report them to the central WSPR database using my station to get an idea of propagation conditions, my antenna performance and just for fun!

Mainly for radios without a separate RX aerial input. This is the simplest and smallest version. I chose to use the relay that W6PQL uses on his projects: see his website www.w6pql.com which has many other fascinating projects.
The W6PQL method was used to improve isolation - see circuit diagram picture.
The Pixie is a well known and very good value 40m CW QRP kit. I used it as a build project during my Intermediate studies in 2015. I’m certainly no CW / Morse operator, but it was interesting to construct and it worked!
Pixie operates on 7.023 MHz, with such low power (<1W) you can see that the “dummy load” supplied is adequate just being a resistor.
Thanks to Ripon and District Amateur Radio Society, six Club members passed their Intermediate exam on 9th August 2015, including me! We're all excited about those new 2E0 call signs and the extra privileges that brings to the hobby.
Next steps include the Advanced remote learning course provide by the Bath Club, organised by Steve Hartley G0FUW with additional support from our club here in Ripon. It's a higher level of challenge, and the first few weeks demonstrate that even higher privileges require some serious study and exam prep.
