In May this Continue reading HF Reception: Urban vs. Rural The post HF Reception: Urban vs. Rural appeared…
The endfed antenna has become one of the most popular choices among amateur radio operators in recent years. Its ability to cover multiple bands and its easy installation often make it the first antenna many radio amateurs put up.

It all comes down Continue reading Boost Your End Fed Antenna with Proper Counterpoise The post Boost Your End Fed…
Looking for an affordable plug play solution for a WebSDR, I Found the WEB-888. The WEB-888 is a WebSDR based on the RX-888 Mk.II receiver and a mini-computer acting as a server.

A less common approach Continue reading How to get started with a remote antenne tuner The post How to get…
When you first see an ionogram, it can look quite difficult to read. With all those numbers, lines, and colored dots, you may not know where to start.

If you already have 100 watts and 200 watts PEP output with the Yaesu FTDX10 and TS-480HX respectively, why would you still buy a 300-watt amplifier? The answer lies in full duty cycle modes like FT8 and RTTY. Both modes demand a lot from a transceiver s final stage, something you Continue reading Review of the RM Italy BLA 350 Plus Amplifier The post Review of the RM Italy BLA 350 Plus Amplifier…
One of my long-term experiments involves receiving on HF. Transmitting on these bands works well with a Cobweb antenna for 10m to 20m and a wire with a CG-3000 automatic tuner for 30m to 160m. Reception in my densely populated area on the lower bands is challenging, often facing up Continue reading Reception comparison: vertical vs. horizontal loop The post Reception comparison: vertical vs.…
If you are a radio amateur or wish to become one, and local regulations do not allow you to place antennas outside your home, don t panic, because there are several solutions. There are stealth antennas, of which the flagpole and metal gutter are perhaps the best known.
