Re: ICOM SSB and ADSP filter kit?

Since this is new to you, I assume you're not too familiar with SSB communications. Because of the type of modulation and frequency range used, it is highly subject to atmospheric noise, both natural and man made. This is primarily from thunderstorms (even at great distances) as well as local man made noise sources. Your used to that nice quiet VHF-FM radio which is totally different. One very effective and little utilized (operator ignorance) method of reducing this noise yet still allow communication is to reduce the RF gain. That's what the control is there for. The default setting on this radio is maximum gain (level 9). Play around with the settings to get a feel for how it affects the noise and signal you are receiving. A setting of around 5-7 will significantly reduce noise while still allowing the intended signal through.
