I hear you Bob. But I still need a preamp with my K2 on 160 and 80M when
using my receive antennas. I use pennants, ewes and flags, which are very
inefficient, but have decent directivity and help me over my transmit
antennas.

Subject: Re: [Elecraft] 80M Preamp request
Preamps are handy to boost the performance of radios with poor front end
sensitivity or for use with antennas with poor efficiency. However one has
to be
extremely careful that the addition of one does not actually degrade the
performance of the radio.
The K2 with it's built in preamp switched on seems to on a par with the
best
radios at present available in the market on this score with an extremely
sensitive RX front end. I would also have thought the ambient noise level
on 80
and 160m in a greater part of the world unless you intend moving to
somewhere like Antactica would have largely negated the benefits of almost
all
preamps. Without being extremely careful with the gain and type of preamp
you are
adding could have an adverse effect on the performance of your K2.
The normal problem is how do sort out the wanted signals from the ever
increasing layer of electronic smog that is emanating from modern
electrical and
electronic appliances, particularly on 80/160m?
