- 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.
