My Kenwood (Trio) TS850SAT has a number of filters fitted for better CW working. I have the 500KHz filter in the 455Hz IF, and the 270Hz filter fitted in the 8.83 MHz IF. Along with the Radio Shack DSP-30, this makes a very nice CW station.
The Radio is coupled to a Yaesu FL2100B or my Collins 30L1 which was built in 1961. (2 years BEFORE I was born!).
My keyer is the famous CMOS superKeyer II (pictured on the bottom right in the photo) from KC0Q, and the Iambic key is a twin paddle model from DK7UD
