This picture explains the various parts of the VU2EVQ design HF linear amplifier circuit. The Pi network of thick resistors form the attenuator for reducing the signal strength
Soldering complex PCBs—especially those involving high-density RF circuits or surface-mount components—requires a shift from “joining wires” to “precision engineering.” When dealing with multi-layer boards or tight footprints, thermal
Setting up a homebrew shack is one of the most rewarding milestones in amateur radio. It’s where theoretical physics meets the smell of solder. Your shack needs to
Had some difficulty in finding the last 100 nF capacitor to be soldered because the slot was a large rectangular slot for C59, unlike the small oval slots
Building a 5/8 λ vertical antenna is a classic project for radio amateurs looking for a low angle of radiation, which is excellent for DX (long-distance) communication. Unlike
The next easy step while assembling Easy BITX according to the manual is fixing five numbers of 1N4007 diodes in the slots shown on the top-of-board silk screen.
That is a fascinating topic, especially for those looking to avoid the losses and narrow bandwidth associated with traditional traps. Controlled feeder radiation usually points toward a G5RV
Operating on the 160m band—often called the “Top Band” or the “Gentleman’s Band”—is a unique experience that requires patience and specific timing. Unlike the higher HF bands, 160m
