... [snip] Only complaint is the Ministry of Truth (CBC) has a 30,000 watt fm transmitter that I can see from my window which causes some problems on the higher SW freqs. Any one know of a filter I could build, or other solution. If you are using an external antenna with a co-axial downlead and the radio is well-screened, Terry's suggestion of an in-line low-pass filter will work. A cheaper solution is a transmission line stub notch filter cut for the offending frequency. Insert a tee connector in the co-ax line. Add a stub of co-ax off the tee, open-circuited at the far end, about a foot long. Trim about a 1/4" at a time until you reach minimum interference. If you go too far, make another one!. Tom |
