Got the sub installed yesterday. I found a strong birdie on 10.115
which was all but eradicated by repositioning the TMP.
With no antenna attached I seem to have more noise on the sub than
from the main board. When I am using the CW mode and using the
2.8 > 1.0 > .250 filters, the background noise becomes almost absent
when I narrow the signal to 50Hz.
With the sub it sounds much brighter (I've never adjusted the Rx EQ
on either the main or sub) and when the filter is narrowed to 50Hz I
can hear a noticeable hiss that is not present at 50Hz on the main
receiver.
When using just the one antenna (don't have a separate Rx antenna
where I am at this moment) the CW signals marvellously pop out of the
silence with the narrow filter as on the main board.
They seem to be as loud on the sub but there is a brighter hiss that
accompanies all the filters from 2.8 to the .250 & DSP down to 50Hz.
Any suggestions?
Thank ye, thank ye,
