While we're on the subject of Wavetek gear. Does anyone know of a source for manuals for 1882A and 1880 CATV analyzers? I've got prelim op instructions for the 1880, but nothing for the 1882A and no service manuals for either. They are both currently functional, but I need to make a few mods.

I have seen 75 ohm cable work well with 50 ohm systems. The slight loss due to VSWR is offset by less loss in 75 ohm over 50 ohm for the same size cable. If one wants to trim the cable to provide a perfect match I would suggest this method. Measure the power at the output of the transmitter into
