-----Original Message----- I am the second owner of K2 #2289 ... I wonder about its rx sensitivity ... it just seems like the PRO 2 has better ears. --------------------------
One has to be careful about confusing audio output with sensitivity. The K2 tends to produce less audio output with weak signals than other rigs and that leads us to conclude it doesn't hear. What it doesn't do is reproduce all signal levels at the same audio level. An S9 signal is just as loud as the band noise in most rigs because their AGCs are very aggressive & flat. They turn the gain down for all signals to match them to the quietest signal, effectively making audio output constant. The K2 has some slope to its AGC. Loud signals produce more audio output than quiet signals. Band noise is quieter than signals. So as you listen to the K2, you don't hear much unless there is a signal there. The K2 is still picking up everything the Pro 2 is, it just isn't amplifying it as much. An interesting test would be to turn AGC off on both rigs, set both with RF gain max and AF gain so they are the same volume, then tune in very weak signals. I bet they both pick them up equally well. - Keith N1AS - - K2 5411.ssb.100 - _______________________________________________ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.
