In my quiet rural location with a 7 element long yagi fed with feeder
totalling about 0.5dB of feeder loss, I find that the K3 is sensitive
enough (just) to hear to the band noise floor.
My Icom 7800 was more sensitive on 6m (& a superb 6m radio in general)
but since the K3 is sensitive enough to hear to the band noise floor I
suspect that adding a premap in my case is not going to help.
Eavesdropping on EME QSO's ( i have yet to do EME on 6m with the K3)
seems to indicate that the in my setup adding a preamp is going to make
little or no difference.
A simple test is to compare the noise level of a Dummy load with the
noise level received on an antenna. If you hear more nose on the antenna
than you do on the Dummy load then it its unlikely that adding a preamp
will help in your situation.

Don‘t complain. Nobody will understand. Or care. And certainly don‘t try
to fix the situation yourself. It‘s dangerous. Leave it to a highly
untrained, unqualified, expendable professional.
