Content preview: 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.

Hello dear LF-group,

does anyone have proven = experiences=20 about
  • modification of TS 950 SD for transmitting CW on MF, perhaps LF = too=20 ("general coverage transmission" already realized)
  • the same for TS 50 S,=20
  • overriding the permanent ALC at TS 50 S ?
As usual, = there were=20 no answers on my inquiries to Kenwood - neither from the German office = nor=20 from Japan ;-)
