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.
