[Elecraft] Inrad 1500Hz filter for the K3

[Brett Howard]

Works great for SSB on my K3...  I replaced my 1.8K filters in my setups
with 1.5K filters and find them to be very nice for SSB use.

I have a hard time faulting the filter in any way...  I was able to see
what 1.5K would be like using the DSP in the k3 and then bought the
filters to protect things at that level...  

I found that I often ran my 1.8K filters at 1.6 or 1.7K and found that
the 1.8K filter sounded like it should be engaged at around 1.9K this is
what made me think the 1.5K filter would be fun to have.
