Hi all. I bought this scope on fleebay for 61dollars spose to work come with 14 day return if it doa. The problem is the its no probes or manuel. I understand it is the same as a 465b but is the milatery version. I found a manuel for it. Know im asking what probed i need for it. Also can i plug this in the back of my B%K 1040 where it say scope.for modulation or do i need a pick up for it. Thanks Ben. :confused:
 

I don't know about a B&K but a decent RF pickup can be fashoned out of a minibox.

Put one SO-239 on one end and another on the other. Join the center conductors with a piece of RG-8 or similar inner conductor with the insulation still on it.

Install a third connector. BNC is a good choice. Make a one or two turn loop around the RG-8 insulation and ground the other end of the loop. Run a cable from the BNC to the vert input on the 465.

Always terminate the lead to the scope's vertical amp with a terminator or resistor of the same value as the impedance of the cable you use for the pickup. This keeps ground loops and junk to a minimum.

    Hello gentlemen and Ladies. I have the dreaded RCI-2990 receive issue where my radio gets distorted when people get close to my location. I found the C90 Capacitor, but I can not for the life of me find the C89 capacitor. Can or does anyone have a picture of the exact location of C89 ? Thank you in advance, Wes
