Radio Interference

I recently got an older radio from my grandmother that has remarkable reception and clarity. I like to listen to it as I go to bed, but the problem is that whenever I want to change the station, I have to turn on a light. This is frustrating and it hurts my eyes, so I'm considering putting a small green neon tube I just got behind the dail on the inside. I just want to know if the inverter for the tube will cause any kind of interference inside the case. Does anyone know anything about this type of thing?

Thanks!

hmm

I'd think neon or flourescent would just about have to cause interference. Nature of the beast.

If the radio is AM, then any

If the radio is AM, then any kind of gas discharge tube (neon, flourescent, cold-cathode, etc.) will create interference. As tomlevens suggests, an LED would be better. You might also consider using a small incandescent bulb running at less than rated voltage. This will create a nice warm glow and a very long life.

oh yea

Those EL wire / CCFL lamps generate TONS of radio noise. But the frequency is usually 1-4Khz so it's probably not a problem unless it's an AM radio.
