[Elecraft] FMT and KX3

[Kenneth Christiansen]

Hi to the gang

The QST article on page 37 of the April 2015 edition looked interesting to me. I started out setting up and testing my K3 along with the free recommended Spectrum Lab software. This looked to work quite well and I expected to get better than ordinary results. Just for the fun of it I fired up the KX3 and to my surprise it did even better than the K3. I had run the temperature compensated frequency setup last year and I found it would go for hours and never move even 1 hz. I ran the FMT after helping teach the ham radio licensing test Wednesday evening. My results were +1.04 hz on 20, -0.14 hz on 40 and -0.77 hz on 80. This is unbelievable that I could do that well with no additional outlay of cash. The last time I tried this was with a Ten-Tec Omni D, a frequency counter, and several home brew cables to measure the VFO, BFO and AF signals. I made the requirements that time about 30 years ago but sure did not have the accuracy of this time with the KX3. 

I feel using the K3 on CW with the spot control and no computer would easily get good enough results to get listed on the FMT web page in the second most accurate group.

This is just one more example of how well these Elecraft rigs work. Thank you for the unbelievably great rigs.
