Description
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: [![Progress](https://img.shields.io/badge/HF%20Upconverter%20%28TH%29-tested-green.svg)](https://github.com/IgrikXD/Easy-SDR) [![Progress](https://img.shields.io/badge/version-8.1.EE-blue.svg)](https://github.com/IgrikXD/Easy-SDR) [![Bug report](https://img.shields.io/badge/Google%20Form-Create%20bug%20report-red.svg)](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/
