[Elecraft] XG1 and K2 question

[Dale Putnam]

Hi Ed,  I calibrate the S meter with the preamp off... that allows the gain of the preamp to be measured and evaluated also.And gives a "standard" of S 9.And, with my two K2s, I seldom use the preamp on any band, until conditions allow, I find plenty of gain, that overpowers the filters with the preamp and amped noise. However, I did, before I realigned one of them, notice that I was using the preamp quite often as the band noise was low... and.. when measured, so was the sensitivity. Realigned... no problem.... and I have gotten verysettled with the low noise from the rx on a quite band... the preamp, many times will add enough noise to make it sound like the band is alive... when if fact.. the band is alive.. but with signals and not so much noise.
Have a great day,

> Hello K2 receiver wizards, what makes more sense when using the XG1 to set the S-meter on a K2, pre-amp on or off? As you well know, pre-amp makes a big difference on 40mtr......I suppose most K2 owners turn pre-amp on from 20mtrs and up, while turning it off 160-40 for better selectivity.
