Peter -
1. If the filter is 1.8KHz
2. If the filter is not defective
3. If the alignment of the TR-7 on USB, LSB is correct
The filter should operate well without using the PBT.
It almost sounds like your alignment of the USB and/or the LSB trimmers
should be looked into.

I have a 1.8 khz narrow SSB filter on my TR7.When using this filter it is
very hard to center on speech and is very echo like.Pressing the PBT
improves things dramaticlly.Filter works great on CW and almost makes you
think it has been mislabelled?Any comments.
Thanks Peter
