My K2 has the 2nd latest chip set in it. It is a 3200 s/n. I have been using it on SSB at 12W. I have the audio compressor on max. I have had hours of great QSO's so far. I know see an option to open up the SSB filter on RX. I use the stock 2.2khz and I like the audio. I find the 1.8khz filter on SSB to be better than that of my Drake TR-7 and Kenwood TS-850. The 1.8khz on the K2 sounds full bodies on SSB. Has anybody done the 2.6khz SSB rx mod? Is it worth the effort, and minimal cost? My only complaint about my K2 is that the RX SSB audio does not have enough low end. The old all transistor Drake TR-7 can sound like tube audio with a few simple cap changes. Has anybody come up with some audio mods. Sure I know the limitations of the LM-386/380 audio chips I was also struck by the choice of transistor used in the RF pre-amp. Why a simple bipolar and not the industry standard Mosfet. I was thinking about trying the bais change in the post IF mixer to get an even lower noise floor. I like to operate pre-ampless when ever possible. I have found this reduces operator fatique. I do have to say that I am still impressed by the K2's RX. However my Drake TR-7's pre-ampless design does give that almost zero noise floor sound. The Rx in my K2 is about as good as my TS-850. The fact that the K2 sounds crystal clear in 1.8khz SSB is shockingly good. The 1.8khz bw on my R-7A is not as clear on SSB on the K2. True as advertised, the K2's RX can compete withe $2000-$3000 rigs. My only nitpick is better pre-ampless performance, and getting that Drake audio sound.
