Afbeeldingsresultaat voor newPCB board for the PWR SWR meter.

With this board you can measure PWR and SWR in a very accurate way. It has some protection circuitry on board for amplifiers. In its most basic form SWR / Temperature.

New features:

  • auto-ranging
  • adapted for VHF – UHF use.
  • wideband input
  • storage of calibration values in EEPROM
  • I2C display less wiring
  • uses only two buttons to operate
  • less wiring
  • Uses arduino nano, easy programming
  • adaptable to most detectors as AD8313 etc
  • mW meter function
  • prepared for remote operation

Preparing a page and a construction manual about at the moment.

PCB only €10 available.

If needed I can supply 2 x AD8307 and a LT1009 (or replacement) and 2 voltage stabilizers (LT1117 %v & 3,3V) for € 5,00

Please ask for shipping costs!
