Should the SMTR OF setting that is almost 20% off the factory default be an indication that something is amiss in the receiver gain chain?
No, my K3 is farther than that from the default. I've calibrated the S meter using the XG-3 and done the RF gain procedure. There is no issue with levels from the IF output and showing normal (calibrated) signal levels at -107dBm (S3), -73dBm (S9) and -33 (S9+40) dBm on either the P3 or SDR-IQ. 73, ...

Last night I was adjusting the sound levels into my sound card from a new LP-Pan2 and could not get to S9 using my XG3 at -73 dbm unless the preamp is ON. I also noticed the S meter was reading S7. I checked the S meter calibration using the procedure in the manual and found I needed to adjust SMTR OF to 20 instead of the default 24. I checked two bands 20m and 40m and got the same results. The XG3 is connected to the RX Ant and the ATU is BYPASS. My K3 has all of the latest firmware updates. SMTR MD is ABS so the preamp is OFF. I've triple checked the settings on the rig to see if there is something I missed (like RF gain) but all check out. Should the SMTR OF setting that is almost 20% off the factory default be an indication that something is amiss in the receiver gain chain? As far as I can tell, the K3 is working fine except I can't drive the sound card output to S9 without the preamp? 73 de Clark/WU4B -- View this message in context: http://elecraft.365791.n2.nabble.com/K3-SMTR-Settings-for-S9-tp7600057.html Sent from the Elecraft mailing list archive at Nabble.com. ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to li...@subich.com
