*Will a Timewave DSP-9 will be of any help with jt65 signals for my FT-871 ?**

*This device is designed for voice and CW noise reduction, I doubt it will make much difference for JT mode signals. Either way, it is designed to take speaker level and impedance audio input and output also at speaker level and impedance. Assuming you meant to type FT-817 rather than FT-871, then you would connect your sound card or rig interface to the DATA socket on the back of the rig which provides and consumes line level and impedance audio and is suitable for direct connection to a sound card.*

* *Does the TCxO filter help considerably - the radio is coming with the CW filter ?**

*The TCXO option is always handy for data operation, particularly if you intend to use it on VHF ad UHF, I doubt it make a big difference on HF or 6m.*

**Does the CW filter help as much as the TCXO does for JT6?*

The narrow CW filter is not useful for JT mode operation.
