Some projects I (KK6MK) have done,
and information, hopefully, useful to others. Most are related to amateur radio.
- GL a Palm Program
- The program runs on Palm Handhelds. It
computes the distance and bearing between two locations.
Favorite locations can be saved in MemoPad and
recalled into the program. This does most of what the
old DOS program did (but no keyer). It is easier to use in
- 10GHz and Up Log Tool
- An Excel spreadsheet. It calculates
and generates logs that can be submitted to the ARRL for the
10 GHz and Up contest. It was done with Microsoft Excel 97,
but as far as I know, it works with newer versions.
- 3600 MHz Synthesizer / mixer
- A synth and mixer. A small board designed by AA6IW and AF6IF. Generates
3600 MHz which feeds a mixer to convert between 3744 MHz and 144 MHz.
Intended as a component for a 24 GHz radio.
- Toaster Oven Soldering
- Others have done this before me, but for the 3600 Board project, I
soldered some boards using a toaster oven. This link describes that process
and how I temperature controlled the oven.
- DistBear Calculation Tool
- An Excel spreadsheet. It calculates the distance and bearing
between two maidenhead grid locations.
It was done with Microsoft Excel 97, but as far as I know, it works
with newer versions.
- CPwin a Code Practice Program
- CPwin is a Windows program to assist in learning or practicing
Morse code reception. A unique feature is that it has a voice prompting
mode, where after a sequence of letters are sent in CW, they are then
spoken in voice.
- EME Tracking Board
- This page describes a replacement design
of the interface board used in the F1EHN EME tracking
system. This board is based on a Microchip 16F877
microprocessor. The board is compatible with the original
F1EHN design. JJ, F1EHN, has now done a nice layout of this
board which is available on his site
- 10 GHz Radio
- The first radio I built to use in the ARRL
10 GHz Contests.
- Satellite Converter LO
- How I reverse-engineered and mutilated a
satellite down-converter to use its Local Oscillator.
- Kenwood TR 9000 as IF
- Modifications made to a Kenwood TR 9000
2M all-mode radio to use it as an IF with microwave
- GLKEY program
- Click here to download the DOS program
GLKEY. This is an old program written in the early 90s.
It's a program that computes distance/bearing
between two locations and also contains a CW generator
that can key a radio. I wrote it to use in the ARRL 10
GHz contest. The distance/bearing portion can read and
save data to files containing favorite locations. It is
in a self-extracting zip file, about 98K.
Sorry, no documentation. Expand all into dir where you will run
it. Look at cfgproto.txt to get an idea of the parameters
that can be entered into the configuration file:
- Mod to an HP Z3816A GPS Timing Receiver
- Description of a modification I made to an HP Z3816A GPS Timing Receiver.
This mod takes 4 existing 19.6608 MHz outputs and converts them to 10 MHz outputs.
