My 'on the air' name is Tom and these pages are dedicated to amateur radio.
The eight–weeks long Morse Code courses of CWops CW Academy are characterized by clear and goal–driven roadmaps. Courses are provided at four levels — from Beginner (Limited or no prior experience with Morse Code) to Advanced (Operating 20+ wpm and desire to increase proficiency for higher–speed on–air activity). There is no cost or obligation to participate in CWops CW Academy Classes and membership is not required. Enrollment is open to anyone with the desire to learn or improve their proficiency in Morse Code.
Morse Code Training shows a way of improving Morse Code proficiency at speeds above 25 wpm.
Morse Code Circuits presents some circuits related to Morse Code signals.
Internet CW,  allows for full duplex, QSK conversations using Morse code audio signals in Mumble voice chat.
iCW at DF7TV presents some information on my setup for iCW.
Kurt Zoglmann, AD0WE provides a well organized overview of CW Resources for learning and training of the Morse Code.
Sverre Holm, LA3ZA provides an excellent unofficial guide to Elecraft K2 modifications.
A collection of links to Semiconductor Data Sheets may be useful for modifications of kits or for homemade projects.
Wes Hayward, W7ZOI described (QST Magazine, June 2001) an RF power meter based on the AD8307 Logarithmic Amplifier and inspired me to build my PM8307.
The Antenna Analyst AA-908 kit (N2APB) of the American QRP Club (AmQRP) has been completed May, 2005 and successfully applied during portable operations.
George Heron, N2APB offers some interesting kits like a DDS-60 Daughtercard for the AD9850 CMOS DDS Synthesizer at Midnight Design Solutions, LLC.
Frank M Doerenberg, N4SPP provides in-depth information and extensive references on the Multi Band End-Fed Antenna. His publication helped a lot during the design and construction of a 160 meter band Sloping End-Fed Half-Wave (EFHW) Receiving Antenna at a local club station.
Dan Tayloe, N7VE has been so kind to send me a revised presentation of his NC2030 CW-transceiver using the Tayloe Detector.
Douglas Hunter, VK4ADC is the author of the software GPS2Time (Windows) for synchronizing a computer clock using a GPS receiver. Using GPS2Time with a G-Mouse VK-162 USB GPS receiver (u-blox 7) my computer clock deviation is less than 150 ms. The precision of the computer clock synchronized in that way is sufficient for most of the digital modes.
David J Taylor, GM8ARV is the author of the software NTPmonitor (Windows) for comparing the time of a computer clock with a number of external time sources.
