Installation; Preparing Mk2R For Use - microHAM MK2R User Manual

Installing MK2R consists of several steps:
1) prepare MK2R to work with your radios
2) install microHAM USB Device Router (the control and interface software)
3) configure the Windows USB Audio Devices (MK2R+ Only)
4) configure Router
5) set audio levels
1. Turn off both radios and make MK2R rear panel accessible.
2. Plug the DB37M of one radio cable set into the RADIO1 connector on the rear panel of the MK2R.
Connect ALL connectors from the cable set to the matching jacks on the rear panel of RADIO1. Each
connector on the radio interface cable is marked same as the jack on your transceiver.
3. Plug the DB37M of the other radio cable set into the RADIO2 connector on the rear panel of the MK2R.
Connect ALL connectors from the cable set to the matching jacks on the rear panel of RADIO2. Each
connector on the radio interface cable is marked same as the jack on your transceiver.
RADIO1 should be your primary radio. Only the original station microphone for RADIO1 can
be connected to the MK2R rear panel mic jack (RJ-45). Using the wrong microphone can
damage the microphone, the radio or MK2R.
4. Connect an RCA cable from PTTIN1 to the PTT output of RADIO1.
Refer to the Operator's Manual for your transceiver for the proper signal connection. PTT output is on the
REMOTE DIN for Kenwood, the Band Data jack for Yaesu (or TXGND), and ACC2 (DIN 7) or SEND for
Icom. If your transceiver does not have an RCA connector for PTT output, it will be necessary to make
the proper adapter.
IMPORTANT: This connection is required for proper VOX operation.
5. Connect an RCA cable from PTTIN2 to the PTT output of RADIO2.
Refer to the Operator's Manual for your transceiver for the proper signal connection. PTT output is on the
REMOTE DIN for Kenwood, the Band Data jack for Yaesu (or TXGND), and ACC2 (DIN 7) or SEND for
Icom. If your transceiver does not have an RCA connector for PTT output, it will be necessary to make
the proper adapter.
IMPORTANT: This connection is required for proper VOX operation.
6. Connect the microphone for RADIO1 to the RJ45 MIC jack. If your microphone has a Foster (round)
connector, use the adapter supplied with the RADIO1 cable set.
7. If your radios have two receivers (FT-1000D, FT-1000MP, FT-2000, FT-9000, Orion, IC-7800, K3, etc.)
connect the fixed level audio output from the second receiver to the SUB RX jacks of MK2R
8. Connect the supplied headphone cable to the MK2R R1+ R2 HP AUDIO jack and plug the 6.3mm (1/4")
plugs into the headphone jack of each radio.
9. Connect your paddles to the PADDLE jack.
