Apologies for piggybacking on this thread, but these seem to be the same as fitted to my Radiovision Hambander receiver - see thread 198465.
If anyone has one surplus I'd be interested!
Thanks,
Roger

Roger,

I don't think the plugs I sent Andrew will fit your Radiovision set, because the dimensions are wrong. Compare those I gave for the plug in post #13 with your 11/3.5mm dims.

I have used Richard's connectors to make up plugs cables for my CR150. I turned up some parts from scrap aluminum to make them fit RG58 cable. One connector is a shorting plug as the CR150 has a balanced aerial input on two coaxial connectors. By shorting one input to ground it becomes an unbalanced input. To put it another way, the aerial input coil primary is connected to the centre pins of the two connectors, so grounding one gives an unbalanced input. The connectors were originally designed to take a cable similar to RG213, which is not that convenient to handle.
The CR150 is working well. I just need to repair the case and front panel...

That's really nice workmanship!

I had a CR100 back in the 70s; don't remember the precise details of the rear panel connections but found it a rather annoying radio to actually _use_ on the HF bands; Somewhat drifty, but was great for listening to Luxembourg on 208M MW.
