Hello elecrafters, i am looking for a device to reduce/eliminate the noise of a 2m ssb-receiver.
What the circuit should do: Reduce (or eliminate) the noise of the rx when no signal is present, like a squelch, but much faster. It should be an analog device, not a dsp-device. It should be external ( e.g. input from the receiverŽs headphone jack). Background: A friend of mine runs a transponder 144Mhz ssb -> 432Mhz fm. The fun with ssb input and fm output is that 2 or more persons can have a conference like on the telephone. There is no interference (whistles when 2 signals present) like on fm , because there is no carrier in ssb. We would like to eliminate or reduce the noise in the pauses. I heard that musicians use a so called ŽnoisegateŽ, but could not find any circuit on the web. Any ideas anyone?
