That may not be necessary as the Prolific driver issue that exists on Windows doesn't exist on Linux, IME. I use an IO Gear Prolific based USB to serial adapter without issue and have for several years over a number of kernel releases as I run Debian Unstable on the box the K3 is connected to. I chose the IO Gear after determining that it generated far less RFI than a cheaper Prolific adapter from another source. > All filters below are in Both Main RX and Sub RX > SSB: > KFL3A-2.8 2.8, 8 Pole Replacement filter, RX, plus Sub RX > KFL3A-2.1 2.1, 8 Pole I have the 2.7 and 2.1 k filters. In my situation when I set the High Cut on LSB to cut out a group that is 2 kHz lower than our net frequency every morning--dialing the high audio frequency down to 2150 Hz--the rig cuts in the 2.1 kHz filter and they are GONE. I would not be without the 2.1 kHz filter, but I do question my need for the 2.8 kHz filter even though it has steeper skirts. I've found that dialing the bandwidth down to 2.6 or 2.5 kHz probably results in the same performance. You have to know, but I've been satisfied with the 2.7 kHz filter and am glad to have the 2.1 kHz filter for rough/contest conditions. > CW: > KFL3A-1K 1 K, 8 Pole > KFL3A-400 400 Hz, 8 Pole I also have the 1 kHz filter that I prefer for some digi stuff and general listening on CW. I also have the 500 and 250 Hz filters and really like the more narrow BW for source and pounce on a crowded contest band. As you are choosing the AM filter you'll have to decide on which to choose so the 400 Hz filter may be a very good compromise for your operating preferences. I appreciate that you're choosing the 8 pole filters. As you have nearby stations which I don't have, this may be a very wise choice. The DSP does a lot on its own but will benefit greatly with good filtering ahead of it and your choices show that you're thinking in this direction. I think you will enjoy the performance. 73, de Nate, N0NB >> -- "The optimist proclaims that we live in the best of all possible worlds. The pessimist fears this is true."
