I bought a 9volt battery for the XG3, today. Running at 0 dBm on 14.020 it puts out a nice clear CW note reading about S7-8 with the XG3 sitting about a foot from the K3. I have a 2m rubber duckie as antenna on the XG3 and the triband beam 50-feet above the shack on the K3. I lowered output to -33 dBm and still have a CW note though now about S1 and hearing a little ac noise coming thru the K3.
I switched to 28.020 and clean signal at either 0 dBm or -33 dBm; switched to 144.220 and good signal there, also. So I guess I hear some ac on 20m. It has nothing to do with the XG3 - End of subject! BTW the signal is just as stable and on frequency at 2m as on 20m. I have had other xtal signal sources that drifted many KHz constantly for the first 30-min to an hour of use. I hear NO drift! wow! There was a little freq. offset at 28.020 but I can always do the calibration if I really care. Frequency accuracy is fine as it is. Note this is with the K3 equipped with the K3EXREF so it is within 2-Hz accuracy. Out of interest I connected the XG3 to my EIP-538 freq. counter and it shows 1.819.997 MHz +/- 2 Hz; 20.020.014 +/- 5 Hz; 144.220.250 +/- 20 Hz. This counter has an internal TCXO that shows no error with my Rubidium standard. I bought it for receiver sensitivity measurements and filter tuning, and the stability is more than adequate for that. I haven't played with the XG3 utility but now that my CoilCraft 7-pole LP filters and filter boards from Clifton Labs have arrived I will try making some response curves, scanning with the XG3. I am making up four LP filters for use on the workbench (and with the XG3 when I want to eliminate harmonics). The filters were free engineering samples. I will show the results on my website. 73, Ed - KL7UW, WD2XSH/45 ====================================== BP40IQ 500 KHz - 10-GHz www.kl7uw.com EME: 144-1.4kw, 432-100w, 1296-testing*, 3400-winter?
