EasyEDA: WSPR-beacon |
WSPR-beacon
GitHub project page | WSPR-beacon
A small hardware device for transmitting WSPR messages based on the SI5351 IC. The device has a built-in TCXO to eliminate SI5351 frequency drift, a built-in GPS module for operation with active GPS antennas, transmission time synchronization and automatic QTH locator calculation, and a simple amplifier based on a single BS170 transistor. PCB is made on based on SMD components and adapted for installation in an aluminum enclosure with dimensions 80 x 50 x 20 mm.
Basic characteristics of the WSPR-beacon:
RF connectors: SMA
Feed line: 50 Ohm coaxial cable
GPS antenna type: active, external
Maximum output power: ~23 dBm
Supply voltage: 5V, USB-B, fuse-protected
Used PCB Material: FR-4
PCB thickness: 1.6 mm
PCB copper weight: 1 oz
