Pre-takeoff checklist
I have a King KX155 radio coupled with a King KI209. I also have a Garmin GNS480 coupled with an Aspen Evolution 1000. When sitting on the ground without the engine running, I tune in a VOR frequency on both units (obviously I won't get anything) and listen to the frequencies. They are fairly quiet, with low hiss. When in the air and I tune in a VOR frequency on both units and listen for the morse code, I hear a lot of noise, which sounds like it may be engine noise. I have to be fairly close to the VOR to hear the morse code over all the noise on the frequency. Also, I need to be fairly close, about 20 miles or closer for the CDI to pick up.
Anyone have an idea if this is a bad filter? And if so, which one and where might I find it in my plane?
Also, anything else I might do to narrow the issue down, short of bringing it to the avionics shop (a good 1 hour flight, a day off from work, and sucking my wallet dry) which I'm trying to avoid for now, would be greatly appreciated!
Thanks!
