Hmmmm, wierd. My filters dropped in. I don't recall soldering. Anyway,
the 400 hz filters are great. I also had a 400 hz filter in my TS440.
When it went to Kenwood for repair, they took it out to do their thing
and would not reinstall it.
I sent email to the new owners (W2VJN) at INRAD and they were most
accommodating and sent me instructions for putting the filter back in.
(I had lost the original. Pretty neat service, considering they did not
make the original sale.
