Kenwood Radio
Tuning Guide


The following is for a Kenwood TK-863G radio, however, many of the Kenwood radios will tune in a similar fashion. The IFR is a model FM/AM–1200S.

In software: enter into "Test Mode" on software and set channel on "5," which has a frequency of 470.2000 for both receive and transmit.

On IFR: type in an RF setting of 470.20000 and put the IFR in "receive" mode. (If you test the radio on any other channel, make sure you put in the appropriately corresponding frequency into the IFR).

NOTE: For any changes to be permanent, you must exit the screens by clicking "OK," if you exit the screen in any other way, the adjustments you made will not be permanent.

Try not to leave radios transmitting for extended periods of time. 

On the wide/narrow option, use wide first.

Check the following "check marked" items on a Kenwood TK-863G (For conventional Kenwood radios, please see the notes for QT Fine Deviation and DQT Fine Deviation):

Frequency Adjust
RF High
RF Low
DQT Balance Wide & Narrow Bands
Max Deviation
(QT Fine Deviation (see note)) Wide & Narrow Bands
(DQT Fine Deviation (see note)) Wide & Narrow Bands
LTR Fine Deviation Wide & Narrow Bands
DTMF Fine Deviation
Squelch Open Wide & Narrow Bands
Squelch Tight Wide & Narrow Bands


1. Frequency Adjustment Option:

A. Set the IFR to basic settings A (put IFR in "receive" mode, meter on "6," Frequency Error on "1K", and make sure you typed in the correct RF frequency for the test channel you are working with).

B. In the Kenwood tuning software, "double click" the Frequency Adjustment option.

Click "TX On," to make the radio transmit. 

You want the IFR Frequency Meter to be "0."

Adjust the on the tuning software until you get the IFR meter to read "0."

2. RF High Power

A. Put the IFR to basic settings B (put IFR in "receive" mode, meter on "150" watts and press "2nd function" + "meter" on the keypads so that the LCD on the IFR displays its digital watt meter).

B. In the Kenwood tuning software, "double click" the High Power option.

Click "TX On," to make the radio transmit.

 IFR Watt meter should equal approximate wattage of the radio (22 - 25 watts for most mobiles, but it depends on the radio).

Adjust the on the tuning software until you get the IFR Watt meter to display the approximate wattage of the radio.

Note: the voltage setting of the power supply used to power the radio effects the wattage output of the radio. 

3. DQT Balance

A. Put the IFR to basic settings B (put IFR in "receive" mode, meter on "150" watts and press "2nd function" + "meter" on the keypads so that the LCD on the IFR displays its digital watt meter).

B. In the Kenwood tuning software, "double click" the DQT Balance option.

Click the "TX On" button.

IFR Screen should display "square waves":

IFR Notes: Lock the inner knobs all the way to the right. The outer knobs should be at .5 and 1 respectively:

C. Check the Narrow Side of the radio.

 
Note: While QT Fine Deviation doesn't have to be checked on a trunking radio, it should be checked on a conventional Kenwood radio. QT Fine Deviation serves basically the same purpose on a conventional radio as the LTR data level on a trunking radio.

A. Set the IFR to basic settings A (put IFR in "receive" mode and meter on "6," and Frequency Error on "1K")

ON WIDE SIDE:

B. The IFR M.D. meter should equal .7

Adjust the on the tuning software until you get the IFR M.D. readings to display the ".7" readings you are looking for.

ON NARROW SIDE:

The IFR M.D. meter should equal .35

Adjust the on the tuning software until you get the IFR M.D. readings to display the ".35" readings you are looking for.

 
Note:
While DQT Fine Deviation doesn't have to be checked on a trunking radio, it should be checked on a conventional Kenwood radio. 

A. Set the IFR to basic settings A (put IFR in "receive" mode and meter on "6," and Frequency Error on "1K")

ON WIDE SIDE:

B. The IFR M.D. meter should equal .7

Adjust the on the tuning software until you get the IFR M.D. readings to display the ".7" readings you are looking for.

ON NARROW SIDE:

The IFR M.D. meter should equal .35

Adjust the on the tuning software until you get the IFR M.D. readings to display the ".35" readings you are looking for.

 

4. LTR Fine Deviation

A. Set the IFR to basic settings A (put IFR in "receive" mode and meter on "6," and Frequency Error on "1K")

ON WIDE SIDE:

B. You want the IFR M.D. meter to equal 1.00 – .99 (it should fluctuate between the two)

Adjust the on the tuning software until you get the IFR M.D. readings to display the "1.0 – .99" readings you are looking for.

ON NARROW SIDE:

Adjust the on the tuning software until you get the IFR M.D. readings to display approximately ".75".

5. Squelch Open

A. Put the IFR on basic settings C (put the IFR in Generate mode, move the "Gen Level" wheel all the way to the left, and make sure the Tone Generator is switched on).

B. Set the IFR to "Generate."

ON WIDE SIDE:

C. Use "Tone Generator" knob (the left knob) to set the put the IFR Modulation Meter to "3".

Move the outer ring of the large "GEN Level" knob to the far left:

You want the squelch to open up on the Wide Side of the radio at about .2 microvolts

ON THE NARROW SIDE:

D. Use "Tone Generator" knob (the left knob) to set the put the IFR Modulation Meter to "1.5".

You want the squelch to open up on the Narrow Side at .2 microvolts

6. Squelch Tight

Put the IFR on basic settings C (put the IFR in Generate mode, move the "Gen Level" wheel all the way to the left, and make sure the Tone Generator is switched on).

B. Setup IFR the same as for checking the Squelch Open ** EXCEPT ** move the outer ring of the large "GEN Level" knob over one notch.

ON WIDE SIDE:

C. Use "Tone Generator" knob (the left knob) to set the put the IFR Modulation Meter to "3".

D. You want the squelch to open up at .4 or .5 microvolts

ON NARROW SIDE:

E. Use "Tone Generator" knob (the left knob) to set the put the IFR Modulation Meter to "1½" or "5"

F. You want the squelch to open up at .4 or .5 microvolts

NOTE: Squelch Tight has to be set above Squelch Open
