I've never owned a Jupiter, so this is an educated guess. I suspect it is a low-cut for the transmit audio. I would set it by ear listening to your transmit audio and by getting signal reports from smart guys on the other end, but somewhere in the 400 Hz range is probably a good starting point.

Think of it this way -- anything below 400 Hz is useless for communications. Telephones, for example, transmit nothing below about 400 Hz. But your mic will produce a lot of audio below 400 Hz, and that will use up transmitter power. so filtering it out is a good thing.

I have not had the time to explore my Jupiter settings --
are you saying that the settings allow the user to select
both upper and lower level rolloff?

So you'd recommend rolloff below 400 and above 2,000?

Thanks! & 73, doc kd4e
