Free to a good home is a vintage Knight Kit P-2 SWR/power meter. These are simple and rugged units with many uses, 5.0/5 rating on eHam. This particular P-2 has the interesting characteristic of being hyper-sensitive. When passing 5W to a dummy load, I had to turn the sensitivity control almost all the way CCW (i.e., min sensitivity) for full-scale power meter deflection on the Forward setting. Another P-2 that I own required nearly full-CW rotation (i.e., max sensitivity) for FS reading on Forward under same condx. If I connect the gift P-2 "backwards," i.e., transmitter to antenna port and vice-versa (forward / reverse paths are symmetrical), sensitivity appears normal. Wiring appears correct and the knobs are new.?

Could make an interesting project or could be a "feature" for QRP ops! Any takers? Best, --David KM6RI
