Subject: TM-731A mod correction The recent posting by VE3EAR was in error with regard to the resistor to be cut to enable out-of-band receive (and xmit). It should have named R25 instead of R57. R25 can be found on the bottom side of the Control Unit circuit card (X53-3250-00 A/3) and is visible and accessible without removing the card from the front panel. The resistor R125 mentioned is actually a zero-ohm resistor, that is, a jumper. The cross-band repeater function is enabled by removing R121, as described. This resistor is zero ohms, and was blue in color without markings. The modification procedure I have seen says to reset the microprocessor twice after making these changes. 73 de James, N5KNX
