I'm afraid I've deleted the original request from a 'VK' from a month or so
ago regarding general coverage Tx on a Kenwood TS940S. 
Out of interest I've done some invesigation and an experiment and it seems to
produce the required result.
Here goes..
Remove the bottom cover
Locate the 'Control' PCB. (The rearmost board).
Find PL17/SK17 - a 5 pin 'harmonica' type - about midway along the forward
edge of the board.
Remove the connector and release the individual socket that connects to pin 5
(nearest to the front edge of the board). This can be done by depressing the
barb on the socket through the hole in the 'harmonica' moulding and pulling
gently on the wire.
Once removed replace the connector and insulate the, now floating, removed
wire and socket.
Replace the bottom cover.
(To remove the mod - just replace the socket into the moulding).
In the experiment the rig produced full output power ( >100W into 50ohm dummy
load) over the range 1.5 to 29.999 Mhz without use of the tuner. When the
tuner was enabled it managed to 'tune' the rig into the same 50ohm load over
the full range. How it would perform into any other load is unknown.
Not suprisingly, I haven't managed to get it to Tx down to 73kHz in fact below
1.5Mhz the Tx is disabled.
I hope this reaches the originator of the request.

Roger.
