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.

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?
