Missing first element in sidetone
I have a number of questions based on my experiences to date, especially today when I operated SO2R CW for the first time. I will raise those questions here as a series of postings, so that anyone with advice or insight can respond selectively.
The operating setup is identical for all questions.
· SmartSDR 2.2.8
· N1MM+ 1.0.7201.0
· Windows 8.1
· Headphones are plugged into the radio, not the Maestro, speakers are not used
· Paddles are plugged into the key jack on the radio and the Iambic setting set to Enabled and to B
Q4: I prefer to operate CW with the sidetone at a very low level, barely audible. While operating today I had the sidetone set at 7. Depending of the AGC-T setting, I find I sometimes cannot hear the first element of a transmission via the sidetone. The element is only missing in the sidetone but is transmitted via RF. The common advice for setting the AGC-T is to tune to an empty part of the band and reduce the AGC-T until the band noise just begins to fade. Today, that occurred at 60. With AGC-T = 60 the first element is totally missing. With AGC-T = 45 the first element is partially audible. With AGC-T = 30 all of the first element can be heard. But at an AGC-T of 30 there are signals in the band that can be seen on the panadapter but cannot be heard in the headphones. Is there a work around for this? There are lots of moving parts here and I wonder if there is some other adjustment I should be making to avoid this. The missing first element is problematic since not being able to hear it ruins my rhythm, especially when sending by hand. It’s as if the AGC attack time also changes as AGC-T is decreased.
