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
