That is exactly what I've been looking for! I've started using a Ten Tec RX320 
lately and it doesn't have a built in noise blanker. I've got an electric 
fence around the horse pasture that I can hear at times. My other main 
receivers have NBing circuits that seem to deal well with the noise, but 
there's not NBer in the RX320. Some kind of external blanking is just want I 
have been thinking I needed to research.
