Parks on the Air
My poor ten month old daughter is home under the weather today. It’s nothing too serious but I knew her teachers would send her home and a day with the baby is still a good day even if she’s feeling a bit puny. While she was napping after lunch, I managed to work eleven POTA […]
Hans Summers’s QRP Labs transceivers are incredible pieces of equipment. I’ve built several and below details my build of his newest offering: the QMX for 20 through 10 meters. I won’t reiterate all the details of the radio which you can find on his website. Instead, I’ll offer all the photos and limited commentary of […]
I’ve built a vertical antenna for 10m, 12m, 15m, 17m, and 20m. This is accomplished through a series of links which create a resonant quarter wave for each desired band.
As a ground plane, I have put down sixteen 10ft radials. These radials come out to just over two wavelengths on 20m, the lowest band of operation for this antenna.
What Kansas doesn’t have in forests or mountains, it makes up for in geographical oddities. Mushroom Rocks State Park is only five acres in area and is littered with a collection of sandstone formations that look like eggs on top of pedestals. For a day in February, it was warm so there were lots of […]
In Part One, I wrote about the interaction between portability and capability with a focus on the radio transceiver itself. This time around, I would like to discuss how to pair a battery to your chosen radio. Again, portability and capability are paramount. Batteries are among the heaviest and bulkiest elements of any portable radio […]
POTA, or Parks on the Air, has to be one of the best ways to liven up your ham radio experience. It combines the thrill of making contacts with the refreshment of being outside. I can’t recommend it enough for hams, both new and experienced. Chances are, there’s a park close to you. Choose your […]
Well, I haven’t been on the air at all in the past six months. My family moved from Arkansas to Kansas back in May. Between moving, house renovations, and my wife and I starting new jobs, there hasn’t been much time for hobbies. When things started to calm down a bit, I looked into getting […]
This particular block should be straightforward. Basically, Diz’s kit ships with a programmed IC for using with a paddle. I believe that we will also be installing the keying switching transistors as well in this section. Components J4 – command button J5 – paddle jack J10 – speed control potentiometer (10k linear recommended; not included) […]
Last time around, I built the power supply and had an absolute blast discovering why components were placed in their particular way. This time, I’ll be building up the audio amplifier section while performing research as I did in Phase 1. In general, this section revolves around placing an LM386, the requisite components that make […]
When building the 5Watter by W8DIZ, K7QO recommends building the power supply first as a troubleshooting measure. If the voltage regulators are installed and giving correct voltages, then you’ve eliminated one potential problem down the line. That, and it is difficult to determine whether everything else is working correctly if you can’t feed power to […]
