Portable 40m Direct-conversion Transceiver Design
Having finished my master’s degree over a year ago now, I’ve started to see my thesis show up on various academic web sites. I decided I should probably link it
7MHz Transmitter with AVR Soft-keyer
In my last post, I went over the design of a Colpitts crystal oscillator design that put out a moderately clean 7 MHz signal. In order to match the output
Testing a 40m Wire Dipole on Mt. Hood
Here’s a quick video showing how I deployed a DIY 40m dipole antenna on Mt. Hood a while back. Though not the most interesting video, I think it shows the
mobile APRS setup…
here’s a picture of my mobile APRS setup in the Jeep. it’s been a fun project from time to time. eventually, i plan on constructing a 2m vertical antenna to
Signals… from space?
none other than. yesterday, i attempted to record some very weak signals for the amateur satellite, ECHO AO-51, with my trusty Yaesu VX-3R. most of my attempts had been unsuccessful
