  • Upgraded project to build with PSoC Creator 2.2 and the 96kHz frequency stability mysteriously improved on some radios. Nothing in the Cypress release notes explains why.

  • Added 96000 Hz sampling rate.
  • Tuned PCM3060 output levels.

  • Calibration is less confusing. The Si570 registers are recalculated when the calibration is changed.
  • I/Q channel reversing for the transmitter. See:
  • Local oscillator tunes down to 120kHz. I don't have filters designed for 600m and 1750m, but the radio is prepared for this.
  • More sensitivity on 20m.
  • 4kHz noise completely eliminated. This was coming from CPU interrupts which have been replaced with Verilog.
  • Better timing for narrow FSK protocols like MEPT_JT(WSPR) and JT65.

  • Initial release.

Source code is on GitHib.

Firmware can be loaded using any JTAG or SWD programming tool that supports Cypress PSoC 3. I use a Cypress MiniProg3. Settings for the programmer application are: SWD, 5V, RESET, and 10-pin. Be sure to disable clearing of EEPROM if you don't want your calibration erased.
