I saw this instruction in the Easy BITX manual “Use a small piece of wire to wire the four crystals to the nearby ground point to prevent “blow

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

Used the the pH reagent from Freshwater Master Test Kit bought from Amazon, which can test 200 samples for pH, ammonia, nitrate and nitrite. Testing pH is quite

In the world of PCB design, the top-of-board silkscreen is the layer of ink used to print identifying information directly onto the top surface of the circuit board.

I have put myself a target of 6 months time for homebrewing this Easy BITX radio. Today morning VU3TBU mentioned that I may be able to do it

Yesterday I had posted about plans to implement thermal protection for my homebrew HF linear amplifier of VU2EVQ design. Had ordered a digital temperature controller thermostat from Amazon

As per the spots on DXWatch.com, AU7RS team for the VU7 DXpedition February 2026, is already active on 10, 12 and 20m bands. Had a phone chat with

Building a reliable HF linear amplifier, especially one utilizing robust components like the IRFP150, requires more than just a solid RF deck. The protection circuitry acts as the
