I am at the point where the first check of the front and control panels check out OK and all seems good but I was wondering how others attached the minature coax to the banana plugs for the RF Probe construction. It looks as if one would destroy the plug as the hole where I think you solder is awefully close to the threads of the plastic screw-on caps. Thanks for the Help!!

Steve,
I didn't solder mine. I just placed the wire in the threads of the plastic and screwed the plug into it pinching the wire against the plug. Seems to work fine for me.

It also looks like you need to save 6 or 7 inches of the RG-174 for the
frequency probe. I didn't see any other uses for it in the manual -- I hope I'm not wrong! Leigh. Sam Binkley wrote: > Steve, > I didn't solder mine.

Steve,
Solder carefully so you don't get solder in the threads. Should some wick through, use a utility knife to cut the solder out of the threads. There is an alternative - don't use the banana plugs at all!!! If you have an old computer power supply laying around, try your DMM prods into the pins of one of the sockets that were used for the hard drive connections - if they have a nice fit (and most do), clip the red and black leads to a reasonable length and solder them onto the DMM end of the RG174. Then stick your DMM probes into this socket and measure away. In fact, you probably don't need RG174 at all (unless the probe is to be used in a really high RF field area) - that end is DC and will be quite accurate even without shielding, so solder about 5 inches of the wire from the computer PS cable directly to the RF probe board. I find this easier than pulling the bananna jacks out of my DMM - just stick the prod tips into the socket. 73, Don W3FPR ----- Original Message ----- I am at the point where the first check of the front and control panels check out OK and all seems good but I was wondering how others attached the minature coax to the banana plugs for the RF Probe construction.
