Sooooo, I went and checked the radio again. Before I pulled it out, I powered it up to check this and that. When I wiggled the new right angle antenna connection, the squelch noise would come on and off a little bit. When I held it in place with the noise and keyed the mic, I didn’t get the antenna light. I thought “aha,“ this will be an easy fix.
The radio comes off the bottom of the mount I made. That mount (with the 10,000 spaghetti wires) doesn’t have to come down to access the CB power and antenna, but it leaves you with a space about three times the size of a pack of cigarettes to play with the wires with my elephant-foot fingers.
I made up another right ankle connector on the workbench, with more attention to detail than I think I’ve ever done on such a thing.
.
I made the pigtail a couple inches longer than the initial one, so I could loop it around and connect it more easily, never stressing any wire. I know from past experience, adding a couple inches of coax isn’t gonna make a significant difference to anything. So I cut the old one out and put this one in very carefully.
When I powered it up, it eliminated the intermittent contact when I wiggled the antenna jack, so that problem was solved. But I still had no signal in or out at all. Wouldn’t you assume, as I have, that the problem is somewhere right there at that antenna connection?
I pulled the plug, and checked the continuity of the coax from the lead to the shield, that was OK. I pulled the jack off the antenna behind the driver side and checked the same thing, that was OK. I was surprised to find a little bit of corrosion, which I cleaned up.
Wondering if it might be interference between the two antennas, I tried the radio with that one side antenna disconnected. No luck. I have to remove the spare tire to access the antenna base at the other side, so I pretty much just gave up for now.
I was so frustrated I just had to let it go for a moment. I cleaned up and came inside.
I’m going to try taking the passenger side antenna loose and see if it makes any difference. If not, I’m going to take another antenna mast and attach it to the coupling behind the driver, and see if that works (only one antenna connected with the new antenna). If not, I’m going to connect the back of the radio directly to the new mast with a new cable, bypassing everything in the truck, and see if that works.
While I have the radio out, I’m going to check it on the test bench again, and wiggle the CB side of the antenna connector to see if that makes any difference. Even if it checks out OK, if I test it with the third antenna again, I’m going to try it with another LTD 29 before I put this one back in.
I’ve done this stuff a 1000 times, but this one really has got me.
If that doesn’t work, I’m thinking of just leaving the window down and shouting up and down the road….
