India, Norm? Hope you're taking advantage of some excellent tandoori chicken and Mulligatawny stew while you're there. Thank you very much for the generous Twinax offer. Were it not for the blue jacket (it's needed for a WWII transmitter), I'd snap it up. Still have some Twinax connectors scavenged from a AS-400 set up stashed around here somewhere for the R-390s...
Fred: I do need some 4 conductor shielded for the exciter power cable, same make up. Any of that around? I gave up on finding cloth covered a while ago. Plenty of 2 conductor AC power cord around with cloth covering, repops for antique lamps, appliances, and radios.
Did think of the twist-and-shield approach, Shane - even found some tinned copper jacket for sale online. Figured I'd ask the experts first then roll my own as a last resort.
Rick, the transmitter is a Meissner 150-B, early WWII. Uses a repackaged Signal Shifter for the exciter/VFO. Here's a link to the manual and schematic that Rob/K5UJ scanned and put online a few years back. Photos near top, parts list and schematic are near the bottom:
http://home.fnal.gov/~atkinson/lowres150b.pdf I did look at some Belden mic cable (8412, 8422 etc) but think I could only find 20-22 gauge stuff. Probably would work just fine? The exciter has provisions for adjustment and calibration to the transmitter, of course. I'm not looking for a museum-correct restoration per say, mainly concerned with things working right electrically. There are also things like cable clamps inside the transmitter that require a certain cable size to clamp onto and so on. Black or even gray jacket is fine. I think the transmitter uses 16-18 inches inside at most, and the manual calls for a 5 foot RF connecting cable. It uses the Amphenol 80MC2 connectors which are sitting here ready to go.
TNX for all the offers and suggestions, guys. Still a few parts away from blast off, but getting there.
