Hi Gary,IMHO, there no great benefit from using an audio filter for QRSS. I tried the "DSP" in an FT897, and also a narrow analog filter (which I use for CW on LF), but couldn't see an improvement on the waterfall screen if the "contrast" and "brightness" controls are properly adjusted. It is more important to have a good noiseblanker in the receiver's frontend . 73, Wolf DL4YHF . |
