Hi Herb, I wouldn't worry about an S-unit of noise increase, especially on 160.
That's bound to happen with any active device like the MFJ-1025; and with the normal BG noise level on 160, I don't think it'll keep you from hearing anything. 73, Mike www.w0btu.com On Thu, Jan 5, 2012 at 4:20 PM, Herb Schoenbohm <[email protected]> wrote: > ...but I am concern about the noise increase when first hooked up with no > antennas and now i see that even the unit 1025 with out a preamp has a > preamp running and the noise maybe coming from it even with the gain pot > all the way down. .. > _______________________________________________ UR RST IS ... ... ..9 QSB QSB - hw?
