Ultimate 2 QRSS Kit →
Hans Summers’ has unveiled his new Ultimate 2 QRSS Kit featuring 500Hz to 40+MHz DDS and plug-in LPF filter modules. The kit sells for about $27 USD and additional band filter modules are $4 USD ea.
The kit supports the following modes:
- QRSS mode (plain on/off keyed slow CW)
- FSK/CW mode (frequency shift keyed slow CW)
- DFCW mode (dual frequency CW)
- WSPR mode (Weak Signal Propagation Reporter)
- Slow-Hellschreiber (frequency shifted slow-Hell)
- Full-speed Hellshreiber
- Half-speed (“DX”) Hellshreiber
- CW (plain CW)
- Customisable FSK patterns
Other features:
- DDS-controlled output frequency (through-pin DDS module, no SMD soldering required)
- Plug-in low pass filter boards (available for 9 HF bands)
- 24-character LCD + two-button user interface
- User-programmable (callsign, message, speed, FSK, mode, etc.), settings stored in EEPROM
- GPS interface, for locking the frequency, timing and location information
- On-chip generation of WSPR encoded message (no PC required)
- WSPR maidenhead locator can be generated from GPS-derived latitude/longitude
- Selectable “frame” size, for stacked QRSS reception
- Plain CW callsign identifier at selectable interval
- Produces 150mW RF output on 30m (lower output on higher frequency bands)
- Higher output power by additional PA transistor and/or higher PA supply voltage
