[Amps] DIGITAL BARGRAPH DISPLAYS

[Conrad PA5Y]

If I were building a new HF amplifier I would be tempted to incorporate a meter and dual directional coupler based on the work of Lofthur TF3LJ. PD0LEW has done some work recently with Newhaven displays which are really bright and look great. Even I managed to get it all working for my VHF PAs. Its cheap and looks good,


Look here for a photos and inspiration.
