This regards the hot wire to the radio....
I already have the speedometer back in the dash and I'm reluctant to take it out again. So, I'm not going to struggle with connecting the radio wire to the ammeter.
I believe connecting the radio wire to the down-stream side of the ignition switch would be just as good ... does anyone see a drawback to that? A possible disadvantage would be if, by doing that, one creates a circuit without a fuse. In that case, one would need to in-line a fuse.

Don't see a problem. In my 1950 the radio can be connected to the accessory position of the ignition switch. Chevs of the 40s has the fused connecting wire for the terminal strip.

In the time frame you are discussing, an accessory block was available from the parts department that mounted under the dash and had two sections, one was constant on, and the other was controlled by the ignition switch. This gave you two choices on connecting the radio, or for that matte, any other accessories that were operated by the battery.

Chevradioman, I tried to call you ... I have mis-place the instructions for the installation of my radio and was hoping you could tell me. (I've had it in the kitchen listening to it for a long time ... it's very nice.)
The black, fused wire is the hot wire. Where does the lighter colored wire go? The radio plays fine with the antennae

The light colored wire is the dial light and is connected to the panel connection on the headlight switch.

Got the radio in. Man, it's pretty skosty. I found a convenient solution for the dial light.... Find the hot wire to the heater switch and connect the radio light lead there. Voltage is supplied when the ignition switch is in the 'on' position.
It's not as easy installing the radio as one might think.
Even though I have modern ignition wires, the radio picks up the 'transmissions' fron the engine running - spark plug wires and coil.
Chevradioman, do you have to pull the radio completely out to change the dial light bulb?

Do you have resistor plugs and I'm sure Ray could help you with some kind of filter I think

Yes, thanks Andy. And my wires shouldn't be transmitting much of anything.
Of course it's an AM (amplitude modulation) radio. A filter could clip the amplitude of a spike, but the body of the spike would still obliterate that part of the desired signal. FM (frequency modulation) can be controlled better than AM.

Interference is a difficult subject. Do you have the hood closed? It may be necessary to place a ground strap on the hood. Make sure the antenna shield is grounded on both ends. If a cowl antenna is used it may be necessary to remove some paint under the antenna base. It may be necessary to go to resistive plug wires or plugs. Generator and coil noises are relatively easy to cure. Use a condenser on both.
