Hello SDR OMs, I uploaded 4 new SDR designs. All 4 new designs are based on use 74HC4053 IC as S/H (sample and hold ) element in demodulators , modulator and transceiver.
1. SDR HF I/Q S/H (Sample and Hold) Receiver-DR3X from 30 kHz-35 MHz for 3 bands harmonically related with 1(one) oscillator or 1 XTAL 2.SDR HF I/Q S/H (Sample and Hold) Receiver - DR2B from 30 kHz- 35 MHz with external LO (local oscillator) 3.SDR HF I/Q S/H (Sample and Hold) Mono band Receiver - DR2C from 30 kHz- 50 MHz with LO (local oscillator) at receiving frequency 4. Low power SDR HF I/Q S/H (Sample and Hold) transceiver- ADTRX1 from 30 kHz-35 MHz with external LO- part1 VY 73/72 and GL in SDR homebrew Tasa YU1LM/QRP www.qsl.net/yu1lm ------------------------ Yahoo!
