Speaky CW/SSB/PSK 5 Band. Available for 80, 60, 40, 30, 20 or 17m bands. A transceiver was described in the ARRL SSB Handbook using bipolar transistors. Assisted means that spotting networks are allowed. 1 with the companion audio codec board the first thing that came to mind was a portable SDR. The Lets Build Something Transceiver project currently has two transceivers on the air and we know of several that are in various stages of the build. Accessories. I built it anyway. I started off by attaching wires to pins 8 and 9 of the Raduino board. I’ll probably change that soon as it is still fairly low output and doesn’t sound that great. It is the perfect solution to your portable operation needs - small, lightweight, wide 20 meter frequency coverage and low current drain, extending the life of your portable power source. Four State QRP Group is honored to have been selected to kit the new transceiver. RTC03 HF Transceiver Controller with Si5351 Freq Synthesizer VFO/BFO + Enclosure. The QRPver-1 v3. We simply take a lot of old ideas and put them into a sort of mental kaleidoscope. Seems to work, with over 20dB of directivity without any adjustments. QCX (QRP Labs CW Xcvr) is a kit designed by Hans Summers (G0UPL), a high performance, image rejecting DC transceiver; basically a simplified implementation of the NorCal 2030 by Dan Tayloe (N7VE) designed in 2004 combined with a Hi-Per-Mite Active Audio CW Filter by David Cripe (NMØS) and combined with commonly used components in HAM and. QRP SSB Transceiver This project was started with some inspiration and ideas from N6QW and DK7IH who both have lots of similar projects on their web sites and Youtube. Homebrew RF Circuit Design Ideas "There is no such thing as a new idea. The transceiver is only for continuous-wave (CW) use, which would normally mean you’d need to know Morse, but thanks to some clever modifications to open-source apps like Quisk and FLDigi, Morse. Adequate knowledge in radio electronics is required in using this Product. The entire transceiver, minus the digital board containing the Arduino, Si5351 and the display, was built on a small 6″ by 6″ copper clad, double sided board. Without an antenna and the HDSDR spectral display bandwidth set to 5. The fact, price still the main concern and consideration to start or to buy a HAM equipment. The RS-HFIQ has three separate DC isolated ground planes; RF/Chassis ground, Baseband/Audio ground and Digital ground. HBR1HF 40m HF Transceiver, HB14HF (40m Band HF Transceiver) This is a complete assembled and tested homebrew mono band transceiver, 2x IRF 530 Final RF amplifier 35-50 watt RF power output, SSB mode, 16×2 char LCD, Si5351 VFO and BFO synthesizer.
