How does a tuner… tune?
Most ham operators know that by combining inductors and capacitors in various configurations, they can tune their antenna impedance to match their transceiver. Many people, […]

Often forums, Facebook pages and other “free-speech” places offer food for thought about many details related to our hobby. This time I stumbled upon a conversation […]
I happened to stumble across some antenna projects showing common mode chokes 1:1 baluns made of some turns of coax wound on T200-2 iron powder […]
In my experience with computer antenna simulators (I mostly use 4NEC2), I had the feeling that those tools, if correctly employed, can be quite accurate. Unfortunately, when working […]
that is the question, for many ham radio operators. A simple, resonant, single band, plain-vanilla horizontal dipole, does really need a 1:1 balun… or not? […]
It can happen that a “PC Programming Password”, set on the Tytera MD-380/Retevis RT-3 “CPS” programming software, is lost or forgotten. If that happens, there […]
The recent Tytera MD-380, also known as Retevis RT-3, is very nice DMR portable UHF rig. However, one of its weak points is the programming […]
One of the most tempting all-band cheap antenna solution when a lot of space is available is the “long wire”. The idea is to lay a […]
In the world of HAM radio, there are several myths that survive through generations despite them clashing with laws of physics. However it is quite […]
(Note: this article is available also in Russian, thanks to Oleg UA9UAX!) [PL-259 vs. N on 430 MHz follow-up] – Many OM assert that they can not withstand the performance […]
