First I want to establish that I'm in the market for a K3 and will definitely buy one---just as soon as I can get one 2-3 weeks ARO. (Hint)
I read the digest and I saw the question was raised about the poor transmit IMD performance of the K3 as reported in the QST review. If this was addressed by Elecraft, I failed to see it, and apologize.

Which with I agree and which (again) raises the question about the transmit IMD performance of the K3. What if the other station is using one? It is commendable to strive to build the best possible receiver but at this point what good it going to be if every other station on the air is a K3? Our receivers don't get to operate in a world where the only interference is from two, pure-as-the-driven-snow, signal generators carefully combined into the front end. Instead they have to deal with all of the garbage transmitted by their neighbors. Shouldn't the K3 be a better, not worse, neighbor than the competition? So I humbly propose a new transceiver "composite" test. Receiver performance shall be measured by using two other like transceivers, operating at full output power, as the signal sources for the measurement(s).
