Partly because some of the TMP cables - particularly those
from the reference boards to the synthesizers - are longer
than necessary and loop into the connector area. 20 mm long
cables would be better than the current 30 mm cables.

Yes! What is the proper way to set the filter parameters?
I resorted to the K3 Utility and had to set the gain for
the CW filter blind since I could not use the S-meter.
