Small Wonder Labs: DSW-II

DSW-II sorozatú adóvevő Kit leírása, változások a korábbi sorozathoz képest: Monoband CW, single-band The DSW-II uses a PIC microcontroller and an AD9835 Direct Digital Synthesis (DDS) chip to achieve crystal-based stability and full-band tuning range. Other noteworthy changes: More output power: 5W max (4W 20M), rear-panel adjustable down to < 0.1W Broad Tuning Coverage* Battery-friendly operation Built-in Keyer (mode B) Morse frequency readout> Receiver Incremental Tune (RIT) Band / RX current 14.00-14.10 / 55 mA 10.10-10.15 / 40 mA 7.00-7.15 / 40 mA 3.50-3.725 / 30 mA

• Coverage is specified for purposes of SFDR(Spurious-free Dynamic range); the DSW may be operated outside of these characterized ranges at reduced SFDR values.

- Receiver response is flat within 3 db over a 150 kHz tuning range - Transmitter output power is flat within approximately 1 dB over the coverage range. Output Power: 5W (4W 20M) max. at 13.8V, adjustable Supply voltage: 8-15V Sidetone: 800Hz, fixed SFDR: >60dB over specified frequency TTDR/ MDS: equal to SW+ IF Filter BW: ~500Hz, any band
