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
Q1: When toggling back and forth between the Slice A entry window in N1MM+ and the Slice B entry window using the Pause key on the keyboard, there will occasionally be a cracking or popping sound in the headphones. The slices are on two different bands. This is not the mechanical sound of the relays switching in the radio but is audio being generated as part of the radio’s audio stream. It is similar to the sounds mentioned in this post:
and the associated YouTube video. Aside from being annoying, it problematic if a weak station begins to call during the noise.
