Nice description, Merv. Would be nice to have the diodes internal with a BNC just for this purpose. Perhaps this could be an add-on kit in the future, if Eric and Wayne will leave any additional space inside.

I made an adapter from a small box that has a male BNC on one end, diodes inside, and a female BNC on the other end, I use a whip with a bnc for general hunting, or a coax cable to a hand held loop antenna for some directional work, depending on freq in use. Works quite well as you can see the noise pattern that is bugging you and see the signal increase or decrease much better than on a metered instrument. For a battery I steal one of my model aircraft LiPo types, have several packs that are 5000 ma 12 volt, they last plenty long to noise hunt. Just have to overcome the idea of taking the P3 out of the shack into the field. :o) 73 Merv K9FD/KH6 > IMPORTANT - If you do this, make sure to protect the P3 IF input with > back to back diodes.
