Hello Tom,
although the TS950SD is in my my shack since
1991..I never made the modification for general tx coverage. I don't think it
can transmit on 500 kHz if you carry out the mod, but probably could be used as
starting point unplugging the rear connection between driver and PA and
replacing with a devoted external PA (I'm using this rig in such way to drive an
external 137 kHz xvtr).
Just for info, I was disappointed about the
frequency stability of TS950SD: a rock in reception (both direct on 137k or via
the xvtr on the 10 MHz band) but on tx, although the PA was cutted out, not
suitable for qrss with several Hz of drift...now I found a a 10MHz Rb oscillator
that is used for LO on the xvrt and divided to 10 kHz to control the PLL via the
rear input.
Let me know if you get a useful signal from the
drive out socket on 470kHz.

Subject: LF: Modifications of Kenwood TS
950 SD and TS 50 S
Hello dear LF-group,
does anyone have proven experiences
about
- modification of TS 950 SD for transmitting CW on MF, perhaps LF too
("general coverage transmission" already realized)
- the same for TS 50 S,
- overriding the permanent ALC at TS 50 S ?
As usual, there were
no answers on my inquiries to Kenwood - neither from the German office nor
from Japan ;-)
Tu es 73,
Tom, DK1IS
