Pse let me have advice on which of the following ARR 2 mtr preamps I should get: P144VDA: 1.0db nf, 15 db gain; or P144VDG: 0.5db nf, 24db gain.
The preamp will be used primarily for AO-7. I operate only portable in a high noise environment here in Manhattan. I doubt the nf difference is at all meaningful in my use. The large difference in gain between the 2 preamps may not be impt. either, that is the real question. My XCVR is the FT-817. Another 817 is used to transmit, running abt 15-20 watts into a small amp. with an Arrow split between 2 booms on 2 tripods only abt. 1 ft. from each other.
So what's the verdict?
Tnx and 73,
