[Elecraft] Sunspots!?!?

Doug,

I lived through cycle 19 of the sunspot signals, and did not find any 
problem with receiver overloading at that time.  We did not have the 
Elecraft gear at that time, but what we had was not up to the 
performance/protection that is typical for Elecraft.  Receivers have 
gotten much better in dynamic range and lowered MDS in general and 
Elecraft rates near the top of the heap.

The AGC in the K2 and K1 (and K3/K3S) can handle the strong signals with 
no problem.  It is not much different than reports of performance during 
a contest where there are strong signals and weaker signals.

If we have a strong sunspot cycle, the weak signals will get stronger 
along with the more powerful stations.

73,

I’m specifically interested in the K1 and K2, but in general, is there a realistic problem with overloading of the front end? Or, assuming that you can hear signals from all over, will the selectivity, etc., be sufficient?
