Hi, Clark: It sounds like you are dealing with two different issues: Minimum Discernable Signal (MDS) measurement and raw audio power.
The MDS that you are measuring with the XG1 should not be associated with how much racket you get in the speaker or phones. A very poor receiver can make a lot of noise! It all depends upon the amount of amplification the receiver has, which is quite different from the sensitivity. First, are you using a bandwidth of 500 Hz for the MDS measurement using the XG1? The MDS you get will depend a lot upon that bandwidth. Since you are measuring the receiver's response to an unmodulated signal and comparing it to the noise with no signal, the narrower the bandwidth, the less noise energy you will detect with the XG1 turned off, so the better the calculated MDS. CW receiver MDS is commonly calculated using a receiver bandwidth of 500 Hz so we're comparing apples and apples when comparing two rigs. All that aside, the audio level is a wholly different problem. I do not own a K1 so I'll leave it to K1 owners to suggest remedies for that.
