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

   Signals at 10368.820 MHz
