Justin,

If you are looking for a CW filter for nearest 500 Hz, I would recommend 
that you add the 400 Hz filter.
The 250 will not give you a bandwidth much over 300 Hz.  You would have 
to tell the K3 configuration that it is a 300 Hz filter so it does not 
switch to the 2.8kHz roofing filter.
The DSP filters in the K3 are very good, but will not protect against 
very strong signals far outside the selected filter width.  The K3 
Utility will help you set up the filters.

If you are looking to use FM on the transverter, you will want a 13kHz 
filter for that.  I don't know if the internal 144 transverter is still 
available, but the TRN menu will properly select and activate an 
external transverter.

Yes, the new synthesizer is a very worthwhile investment, you will not 
be disappointed.

73,

I notice that the rig has the original 2.8K filter installed, so I’m thinking that I should add a few more filter to optimize performance with some different modes.  Were I to add a 250 HZ CW filter would that also work at 500 HZ?  Also, is there any advantage to upgrading the original synthesizer to the KSYN3a?  I hear that does make the rig a bit quieter.. Would I notice that during normal use?  I’d also like to add some kind of a transverter so that the rig could extend it’s capabilities out to 144 MHZ, is that possible, are there any of those units available on the used market?
