Subject: Kenwood TS-570D MARS/CAP Modification.
This modification is provided "as is".
It is illegal to operate outside the limits of your class license or
permits.
1. Disconnect the power cord and antenna coax from the transceiver.
2. Remove the top and bottom covers.
3. Remove the top screw from each side of the front panel assembly.
4. Loosen the bottom screw from each side of the front panel assembly.
5. Carefully rotate the front panel forward to gain access to the
Control board (X53-3690-10).
This board is mounted vertically against the body of the
transceiver. It is not the board
that is mounted in the front panel assembly.
6. Locate and remove the chip resistor R41 from the Control board.
7. Assemble the transceiver then perform the CPU reset procedure by
holding the A=B button
depressed as power is turned on.

Fred,
I just did the MARS/CAP mod on my NEW (2 weeks old) TS-570D.
The surface mounted resistor you state in your description is correct.
The correct item number on top of the resistor is "102". There is no
R-41 that I could see even with a magnifying glass.
Thank you for your mod pages and excellent web site.
Jim, N3BRS
