identification of bandscope markers
Posted: Wed Jul 31, 2019 6:47 pm
I am curious if anyone can tell me what all the markers on the bandscope are. I believe that the red line marks the current receive frequency and the highlighted area is the bandwidth filter. What are the yellow markers?
Also, I notice that if I switch from USB to CWU:
-- the frequency goes up by 600 hz but the red line stays at the original frequency, The frequency in the display appears to be at the center of the CW bandwidth. Why does the frequency change and why does the red line no longer represent the receive receive frequency?
-- The bandscope grid has frequency indicators at the bottom and the top on the grid and they are offset from each other. Does the bottom represent the receive frequency and the top the transmit frequency?
