In the shack a Kenwood TS-830 was driving a MFJ Active filter which drove
the bookshelf speaker.  This was loud and sounded good (*almost* as good
as my National HRO-5TA1, circa 1946 !!!).  I'm wondering if similar audio
quality could be obtained if the K2 drove an the active filter with a
good amplifier (or equilizer etc.) and a good bookshelf er???  Has anyone
tried this? If so please comment."

Speaking of the TS-830, I use my old TS-830S speaker (an SP-230 with
selectable passive filters) with my K2.  On SSB the audio is quite
adequate and  sounds good.  I drive it with the K2's rear panel audio
output.  I also use an old pair of Radio Shack "Nova 20" 8-ohm stereo
headphones which plug into the phone jack on the SP-230 and the SSB audio
is loud with them also.

On SSB, I never have to increase the audio gain pot on the K2 beyond the
9 o'clock position with either the K2's internal speaker or with the
outboard speaker or with headphones, however on CW there is not adequate
volume even with the audio fully clockwise unless I turn the AGC off when
receiving weak signals.  (No, it's *not* a K2 filter alignment problem!)

I still have the TS-830S and its companion VFO-230, which I'll sell when
I get my new Ten-Tec Orion, but the speaker is quite handy and I'll keep
that.
