A summary of common calling frequency for each digital mode on that band.
RF Power measurement using a DVM, RF Power measurement using an RF detector, RF Power measurement using an Oscilloscope and using a Spectrum Analyzer
QRP is a Q-code originally meaning reduce power, but now has come to mean operating a radio that outputs 5 watts or less for CW or 10 watts for SSB.
Notes, hints and tips on starting with morse code, how to approach learning the code, how and when to get on the air, learning and using abreviations, common Q-Codes and a sample morse code QSO.
This a well performing, simple two band transceiver. The transceiver design is inspired by the S7C superhet. A dual-band transceiver with a crisp receiver and a clean SSB signal
An easy to build 6 watts SSB transceiver for 14MHz. BITX is an easily assembled transceiver for the beginner with very clean performance. Using ordinary electronic components and improvising where specific components like toroids are not available, It has a minimum number of coils to be wound.
QRP is a way of operating that involves using low power transmitters, that are no more than 5 Watts for Morse or data modes, or 10 Watts pep for voice. Introduction to QRP operations
A two tone generator is an essential test gear made with just four transistors that helps you evaluate your amplifiers, mixers, receivers for distortion. Distortion makes all the difference between a pleasant receiver and a horrible sounding one, between a clean transmitter and bad, splattering one on air.
The Specan is actually a very simple but robustly built receiver. it is, in essence, a double conversion superhet receiver with 112 Mhz and 12 Mhz Intermediate frequencies. The first mixer uses an Si570 as the local oscillator. The Ardiuno that controls the Specan is a very flexible microcontroller board that you can program in simple C language
