EasyEDA project for easy and quick build HF upconverter for work with shortwave bands on SDR receivers. Project include schematic for HF upconverter and PCB. File "HF Upconverter PCB (TH): Converter (SINGLE-LAYER OPTIMIZATION)" has been developed for more convenient producing of a PCB in home conditions using toner transfer or photoresist method. ## Current development progress: [](https://github.com/IgrikXD/Easy-SDR) [](https://github.com/IgrikXD/Easy-SDR) [](https://docs.google.com/forms/d/e/1FAIpQLSeUFM1p15N_vk8X_blSnZp6jPlZe_qRhiRlmntscx6jF2yRqw/viewform?usp=sf_link) **Frequency range:** 0(depends of mixer) - 30MHz; **Power:** USB type B, DC 5 V; **RF connector:** SMA; **Feed line:** 50 Ohm coaxial cable; **Used PCB Material:** FR-4; **PCB thickness:** 1.6 mm; [Easy-SDR project page at GitHub][1] Original schematic: [Basic SDR Upconverter v1.0][2] Buy SDR receiver: [RTL-SDR.COM][3] ## List of changes: Version **8.1.EE**: changes of the toggle switch (SW1) on the printed circuit board, now the contacts of the case are soldered to the GND area. Version **8.0.EE**: the RF line width has been recalculated using [Saturn PCB Design V7.08](http://www.saturnpcb.com/pcb_toolkit/). At the moment, the resistance of the RF line is close to 50 Ohms. ## How to contact me? - E-mail: igor.nikolaevich.96@gmail.com - Telegram: https://t.me/igrikxd - LinkedIn: https://www.linkedin.com/in/igor-yatsevich/ [1]: https://github.com/IgrikXD/Easy-SDR [2]: http://www.on1bes.be/sdr_up_conv_v1.0_ade1_125_en.html [3]: https://www.rtl-sdr.com/shop/
