[Elecraft] OT: CTCSS tones for repeaters

One additional note. When repeaters send CTCSS tones, many 
radios depend on the poor low frequency performance of small 
speakers to suppress the audio tone. This approach fails when 
using a car audio system to get enough volume to overcome wind 
noise etc. Having a fairly steep rolloff below 300 Hz available 
would help with this situation.
