Bob,

Good idea to change the thread title!

What in this list will improve TX audio -- other than the KSYN3A (which I already have in my K3)? Speaker audio improved, yes, but that seems to be RX only.

FWIW -- I think the K3 is already a "great" radio, but agree that the K3S will be still greater. But for me, if I had to choose only one item on the list below, it would be the KSYN3A -- and I've already chosen to add it to my lowly K3 :-)

Of the other items below, I've already added the coverage of 630 m and below, and will likely add the new DSP board with its RX audio improvements when it comes available.

Here's the enhancements and improvements to the K3S

From the K3S data sheet:
* Enhanced look and feel, with new LCD bezel, soft-touch VFO knob * Ultra low-noise synthesizer for exceptional strong-signal receive performance and transmit signal purity (KSYN3A) * USB port—integrates remote control and line-level audio, eliminating the need for a PC sound card and audio cables * Second preamp for 12-6 m weak signal work (on included KXV3B module) * Multiple attenuators, providing steps of -5/-10/-15 dB * Lower-Loss ATU option with true bypass relay (KAT3A) * Redesigned AF output circuitry for outstanding speaker audio * Accurate, high-speed CW transmit even in SPLIT mode * Coverage of the 630-meter band (~470 kHz), and lower

IMO - these are things that will make a good radio a great radio.

73 Bob, K4TAX
