Projets
Translation pending…
This page will cover some completed projects, in providing schematics, photos and explanations. Future projects will also be exposed here and members wishing contribute are welcome.
A simple short list to start:
Projets already done:
- Building a receiver – Softrock Ensemeble RX2
- Building a QRP transceiver Softrock Ensemble RXTX
- Home made dipole antenna, 40m band
- Building twoJ-Pole antenna (144 & 440 MHz)
- Setup the shack area in the Lab
Work in progress:
- Design & build an home made HF 200W PEP amplifier, for the 40m band
- Multi-band grabber (based on a QS1R)
- Build a new wire antenna. Dipole with traps to cover the 40m/20m bands
- Tiny QRSS / QRPp transmitter, with home made oscillator (possible extension to a self-contain WSPR,using a micro-controller Arduino or Microchip).
- Modification of commercial pager to use them on amateur bands + modulation tool used to create a local network of pagers.
- Adapt an old TTY machine for the amateur band
- Spectral analyser (waterfall) and demodulator using HTML5/Javascript
Possible further projects:
- SDR receiver based on a FPGA/ADC 100Msps, Ethernet output
- SDR receiver lite based on a Microchip or ATmega and an audio 96k ADC. Ethernet output
- Transverter 1.3 GHz
- Instrumentation signal generator 1.3 GHz (PLL & ref. osc. 10MHz)
- 1.3 GHz antanna, ex: Quados
Next radio experiments:
- QRSS emission on the 40m band
- Trying some digimodes on the 40m
