               TM-701A REPEATER CROSS-BAND MODIFICATION (REVISED)



This Mod is from KENWOOD



Perform The following modification to allow the TM-701A to operate in the

repeater cross-band mose.



MODIFICATION:



1. Disconnect the power supply and antenna.



2. Remove the top and bottom covers (12 screws).  Disconnect the speaker wire

   from the transceiver.



3. Locate the green jumper wire shown in figure 1. Using a sharp pair of wire

   cutters, cut the jumper in half.

   CAUTION:Cutting the green jumper allows the TM-701A to transmit from 142 to

            151.995 MHz. Protect your license by only using frequencies that

            you are authorized to transmit on.



4. Solder a jumper wire to the foil side of the TX-RX board as shown in Figure

   2.

5. Assemble the transceiver by reversing steps 1-2.



6. Reset the microprocessor by holding in the MR key as the power is turned on.





The repeater cross-band operation allows the TM-701A to receive on one band and

re-transmit the signal on the other band. The TM-701A alternately displays the

two bands until a signal is received. The transceiver will then display the

band that is re-transmitting the signal. The shift function cannot be used

during the repeater cross-band operation. If the TONE or CTCSS function is

required, only one EIA tone can be used for the two bands.





OPERATING PROCEDURE:



1. Select the operating frequencies for both bands.



2. Set the squelch control to the threshold point. The TM-701A will transmit in

   the repeater cross-band mode if the squelch control is set too low or a

   signal is received.

3. Place the transceiver in the duplex mode (F + DUP).



4. Press the F key for longer than one second. The F indicator will flash.



5. Press the LOW key. The transceiver will now enter the repeater cross-band

   mode of operation.



6. To cancel the operation and return to the VFO mode, press the VFO key.
