A power meter is almost a necessity when building your RF equipment. Since I did not have one I decided to build one myself.

IC202 makeover
I decided to upgrade my old IC202 with some new features, a long time ago I already added a new frontend based upon a BF891 and SBL-1 but I now wanted to have a digital readout to have a better and more accurate frequency reading.
ATV generator
For Amateur Television I was looking for a simple and standalone video generator that could do the following:
- Show predefined pictures in graphic format ( .jpg )
- Play movies (in mpeg format)
- Play sound (MP3 or WAV format)
- Simple to use
- Network capable (uploading pictures)
- PAL output
144 MHz Power Amplifier
Finally my 144 MHZ QRO amplifier is ready. Based upon PCB of F1JRD and a BLF578 of NXP. The PA is capable of making > 800W but due to antenna limitations it can only run at about 400 Watt.
