PIC16F876A LCD RF Power Meter with Data Logger: PM3

  

 

 

 

 


Dual Channel LCD SWR METER by I2TZK

I2TZK has made enough efforts in making this Dual channel SWR Meter with Data logger. A free PC software is also offered by Tony/I2TZK

 


40db RF Attenuator for PM3A

 

HF 40db attenuator is basically designed for PM3A RF Power Meter. However, it may be effectively used for other measuring purposes.

 

 


Antenna Matching Balun for QRP Radios

 


PIC16F877A LCD HF 100W SWR Meter: FD-SWR-HF

This 100W HF 2x16 LCD SWR Meter uses advanced PIC16F877A and have accurate RF Measurement pick-up board using a toroidal indictor bridge. Has back-lite control and simple two button menu operation. 

Meter displays Forward, Reflected, actual power to antenna and SWR.

 


PIC16F88 LCD VHF SWR METER : FD-SWM-VHF

This 2x20 LCD HF/VHF SWR Meter measures & Display SWR and Forward power and has a bar graph too. Uses PIC16F88 with inbuilt 8MHZ Osc. and has 3 front panel buttons for menu control.

Uses standard PL/SO239 sockets. 

 


PIC 16F876A 500MHZ Dual Channel RF Power Meter with Data Logger: PM3

PM3 is a version of PM2 with Data Logger Output and supports remote LCD & Menu Button placement. 

PM3 has a remote Sensor Board:

 


A Simple AD8307 RF Power Meter: FD-PM1

 

Coming soon

 

This is a simple AD8307 based 500MHZ RF Power meter which uses 10 LEDs  giving 10db step reading from -80db to +10db. Uses a LM3914.

 

 


RF Dummy Load 50 Ohms 10W

 

 

Resistive dummy load for 50 ohms will handle approx. 10W and has detector output for measurement
