[Kenwood] Filter 500Hz for TS450

Sun, 02 Mar 2003 21:37:11 -0600

As an interesting side effect, if you get both and turn them both on, your 
bandwidth turns our to be about 300 Hz. It seems that the filters are not 
centered so they end up with mismatching bandpass, the 8.83 MHz filter has 
a lower bandpass than the 455 KHz filter.
I plugged the audio of a TS-450 with a lot of band noise and ran a FFT 
program to map the frequencies that would pass through the filters and 
noticed that the two CW filters have  a different center frequency.
