BEACON FOR 10 GHz BAND
Project for beacon in 10GHz band (10368.820 MHz), based on Wade W1GHZ's PCB x 9 multiplier
The beacon will have ID in classic CW and JT4G digital mode and will be installed in KN44HD
BEACON STRUCTURE
Copper pipe cap and brass nuts soldered
Beacon work progress December 2025
Lab test - ADF4350 EVB for 1152 MHz, controlled with Arduino as Signal Generator and Attiny 13 microcontroller
Beacon work progress May 2026
ADF4350 EVB module have a very low signal level at 1152.0911MHz and 20dB RF amplifier added
Beacon work progress June 2026
For better frequency stability, I replaced the PLL's internal 25 MHz reference with an external 10 MHz reference
Because the Atiny 13 microcontroller does not fit the JT4G digital ID message, it was replaced with the RP2040 microcontroller
JT4G needs very accurate time periods, a GPS controller was added
Beacon work progress July 2026
