[Elecraft] K2 - bargraph reading OK?

[Don Brown]

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
