A while back I decided to run my R8B off an external power supply. I
can't say my decision to do this was based on any very sound reasoning. I'd read some old posts in rrr about how keeping heat out of the case would promote the long term health of the receiver and, being a little paranoid about protecting my investment, I decided to go with an external supply (despite the fact that the R8B really doesn't get very warm when running off its own internal supply). My guess is that that there's no real need to use an external supply and that my desire to protect my investment made me a sucker... In any case, I've tried a couple of external power supplies, most recently a 13.8 VDC / 3amp supply from Radio Shack, and both of them introduced at least some kind of noise or hash into my reception. It was often very subtle, but enough to be a real problem when it comes to weak signals. When the R8B is running off its own internal supply, it's much quieter. It seems to like it's own, internal supply. So my question is, should just I forget about using an external supply? Thanks in advance! Steve |
