Well, I guess KD5NDB disagrees with Elecraft also, as well as with me. I say again (for the third time), they told me that it was best that the 4 MHz be set at exactly 4000.000 kHz. If not, the built-in counter is not accurate. And, as I said before, because of temperature changes, the VFO doesn't retain accuracy, so why bother? If he can get Elecraft to change their opinion, fine. 73, de Earl, K6SE
