...he thinks it's funny that I stepped in it

maybe my 858 noise blankers needed the mod if it stops images from happening from strong signal mixing. whats the mod?Based on my experiences with both boards, and having both the President (D858 AM/SSB board) and the Uniden Washington (MB8719 single AM conversion board) along with the Cobra 2000 GTL (MB8719 dual AM conversion board), I prefer the D858 chassis for sensitivity, as both my President Washington and Teaberry Stalker II can RX a signal down to .32uV (.32 microvolts). Both the MB8719 boards drop RX at about 3uV (3 microvolts).
However, provided that you do not do the NB/ANL mod for the D858 chassis, the MB8719 boards do have better NB/ANL filtering.
For me, at least where I live adjacent channel rejection on the D858's and the MB8719's are very close, not enough of a difference for me to choose one over the other. I don't have any issues with my D858 boards being muffled in any mode.
It's really just a matter of preference. You go with what you like.
and i found the specs on a 148gtl that show .25microvolts sensitivity for ssb. i know its tremendously sensitive, i can hear things on it that my icom and yaesu dont. if yours tests down to only 3 microvolts ssb then you have a dead if stage or need an alignment
