4. 2 x 16 LCD Display with BL

5. Signal Level measurement in dbm, vpp and rms

6. 50 ohms input impedance for both ranges

7. Frequency "off-sets" set by PC program.

8. Free PIC Firmware & PC WIN Software by Tony/I2TZK

Counter is designed on a double sided PTH Board and works on USB or external DC12V power. 

Fc3 is designed and developed for Radio Amateurs looking for economical frequency counter for their hobby work and wish to measure RF signal Level at the same time. 

Analog Device's AD8307 is used to measure RF level very accurately in DBm, Vpp or RMS. 

Counter works with PC or as a Stand-alone. PC Connection is auto detected and so is stand-alone mode.

Front panel push buttons are provided for RF Meter Mode and HF to VHF Frequency measurement modes.

A PC program is specially designed for FC3 by Tony/I2TZK is provided for configuration of IF Off-sets and AD8307 related parameter configuration thru USB interface.

FC3 Complete KIT uses (and Includes) AD8307, ADA4789 and MC12080 in SMT package and are supplied pre-soldered on PCB for those who do not like to solder these tiny devices. Assembled FC3 may also be available but buyer need to calibrate RF Measurement using PC software.

Kits and assembled FC3 are available. Only use Standard Osc provided with kits. Do not use TCXO in place of supplied Osc as the TCXO is not yet tested by me.
