160m Short Vertical Loft Antenna - This is a very small vertical 160m antenna that fits in the loft of even my small house. It was built as a way of getting a signal out on 160m for local AM contacts, but the local noise level was far too high to allow it to be used at night for this purpose. However, on WSPR it did a pretty good job with WSPR spots from a very long way across Europe being received when running 2.5W out.

Homebase 10 - The Homebase-10 is a simple to make wire halo antenna for 10m (28MHz) built using parts available from the local DIY store. The resulting antenna is very effective on 10m despite its small size and light weight. Also shown is a dual-band version for 10m and 6m.

Emergency ham radio frequencies - These frequencies have been adopted into the bandplans of each IARU region to be a focus for emergency communications in their areas. They are not absolute frequencies but instead are centres of activity and emergency communications may be found around 20kHz from these centres. Some countries may maintain other emergency frequencies in their own bandplans due to local requirements, QRM etc

Remote CW Key Project - A simple DIY project for a remote cw key connected to your Flex Rig (actually it can be any other rig). On the remote side it uses and Arduino Uno board and a cheap HanRun Enc28J60 ethernet shield. On the local side it uses a key (better a keyer) connected to a serial port of your pc

Specan Spectrum analyzer - 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

2m to 70cm Transverter Circuit - A 70cm / 432 MHz Transverter Project transverter circuit is an electronic device that converts a radio signal from the 2 meter to the 70 centimeter band and vice versa, allowing a single transmitter/receiver to be used for both bands. It consists of an IF stage, local oscillator, frequency multiplier, and amplifier. The circuit must be designed for minimal signal loss, noise and intermodulation distortion.
