High Standing Wave Ratio (SWR) is a common frustration when setting up or maintaining an antenna system. It indicates that power is being reflected back to the transmitter
Getting your amateur radio license is like getting a driver’s license: you’ve passed the test, and now you finally get to get behind the wheel. The “best” gear
When you’re building an antenna, you quickly realize that the math on paper rarely matches the reality on the roof. One of the biggest culprits is the Velocity
Ever since I heard of BITX radio, I have been wondering how that name came. The BITX (Bidirectional Transceiver) is called such because it utilizes a unique radio
Testing method modified from: #132: How to test MOSFETs with a DMM – a few methods… https://www.youtube.com/watch?v=gloikp9t2dA&t=106s (W2AEW). (I am using analog Multimeter instead of a digital one.
VU2EVQ Linear HF Linear Amplifier is useful in combination with uBITX QRP radio. Will give about 100W output on 40m and lower bands. About 40W output expected on
We are currently experiencing a G4 Severe Geomagnetic storm resulting from a solar coronal mass ejection which occurred on 18 January 2026. Read that crew on the ISS
Today morning I woke up to see this on the NOAA Space Weather Prediction Center! Friends in high latitudes will be flooding X with wonderful displays of Aurora.
Predicting amateur radio band openings is a mix of analyzing “space weather” (the solar engine) and monitoring real-time activity (the results). For a seasoned operator or a technically-minded
For the 80m band (3.5 MHz) in my location today, the best window depends on whether one is looking for local Kerala/South India contacts or trying to reach
