  "FT650 NOISE BLANKER MOD"

If you are unhappy with your FT650 noise blanker here is a quick mod.
The mod involves shorting diode 4013 which will increase the gating
time of the agc line to the noise blanker.
This is located on the if board.
This will inprove the noise blanking by several S points under heavy
power line noise.
