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 […]
When I first began my ham radio career some seven years ago, I was immediately drawn to kit building. One of the first kits that I discovered was the 1Watter, offered by Kits and Parts. I held off too long on getting that particular kit because of the small SMD parts and the lack of […]
