Hi When you calibrated the meter during alignment and test part 1 the receiver was not functioning because it did not exist yet. Now that you have the 40 meter receiver working you will need to reset the calibration on the S-meter. You would normally wait until the K2 is completed to do all of the final calibration but you can do it at this stage if you want and then check it at the final test and calibration.

Hi all, I just finished "Alignment and Test, Part II" on my K2 S/N 5361. All readings are well within spec and I've also quickly compared the receive on 40m to my TS-570DG. It's afternoon here so no whopping broadcast signals yet, but so far what I've heard with the K2 seems very promising. I only have one question. When I disconnect the antenna from the K2 and put the RF gain to maximum, the S meter shows S7 while I would expect it to drop down to bottom scale. The meter has been calibrated during the testing of the display unit, all was well then. Connected to the same antenna as my TS570 the K2 shows around 20dB higher signal levels on the meter. Should I recalibrate the meter? According to the manual recalibration is only necessary after changing the AGC threshold which I haven't done. I've only aligned the IF amp and the 40m bandpass filter as per the instructions on p64 of the manual. I do not have a signal generator here so if you're sending in any hints please take this into account. Thanks for your help Glenn ON4WIX _______________________________________________ _______________________________________________ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.
