If your rx is not good at low freq audio.. maybe it would be easier to just
calibrate down 100 hz per the other radio?
100 hz is hard to hear if it is being taken out by a filter...
Have a great day,

Dale,
Thanks for the info. I’ll tune in WWV on one of my other Ten Tec rigs and zero
beat the Scout counter to it.
Not a big problem but hate to have to keep tuning 100 Hz above the station I’m
working on the air.
