Kenwood Trio R 600 Frequency Dial seems to have presets will not dial full band

Based on the information you provided, it seems like the Kenwood TK-2000 radios you have may have been programmed with the wrong band split. The TK-2000 is available in both VHF and UHF frequency ranges, and it's possible that the radios you have are actually UHF models, despite being listed as VHF frequencies when you read the radios.
To check if your radios are UHF or VHF, look for a label on the back of the radio that specifies the frequency range. If it says UHF, then the radios can only accept frequencies in the 400-440 MHz range. If it says VHF, then the radios should be able to accept frequencies in the VHF frequency range.
If you've confirmed that the radios are indeed VHF models, then it's possible that the band split settings may need to be adjusted in the programming software to match the specific VHF frequencies you're trying to program. I recommend checking the manual for your programming software to ensure that you have selected the correct band split settings before programming the radios. If you're still having issues, it may be helpful to contact Kenwood customer support for further assistance.

PIONEER VSX-D903S - A/V Receiver
PIONEER CU-VSX079 - Remote

Here's the basics: Make sure your receiver is in the Tuner mode, by selecting Tuner on either the remote (grey button), on the receiver, or from the GUI menu. (The display will also show TUNER.) There are a couple of different ways to tune a station. One method is with the remote. Use the Band button on the remote (or via the GUI display), or the FM/AM button on the receiver, to select the frequency type. Use the Freq/Ch buttons on the remote to tune, the number buttons for presets (30 presets total. Examples: Preset 5, simply press 5; Preset 15, enter 5-5; Preset 25, enter 5-5-5). You can also use the on-screen GUI menu and the remote to tune stations, using the lower grey buttons. If you want to tune directly, via the receiver, press Select, to switch between frequency tuning and presets (displays ST CALL) mode. Use the Multi-Jog dial to make your selection in either mode. The easiest way to program a station into a preset is to use the onscreen GUI menu. [NOTE: The GUI mode (TV Monitor Video Out, composite video) is active when an amber (orange) ring glows around the Multi-Jog dial (the GUI button on the receiver will also glow simultaneously). Use the remote lower grey buttons, or use the Multi-Jog dial and Select, to move the cursor and select commands on the TV. This A/V Receiver handles composite video/S-video, and Stereo/Dolby 3-Channel/Dolby Pro-Logic audio only. (Pre-ATSC/HD video, Pre-Dolby Digital/DTS multi-channel surround audio)]

Welcome to FixYa.

You need to use the remote control to access the radio station frequencies.
Follow the instructions below:


Thank you for using Fixya. Have a great day!

1.Select the radio band and tune in a desired radio station you wish to store in the preset memory.
2 .Press and hold any one of the Preset buttons (1 through 6) for at least 2 seconds until the station frequency on the display blinks.
3. Press the Preset button into which you wish to store the station while the frequency display is blinking (within 5 seconds). The display stops blinking once the station has been memorized. The display shows the band, preset No. with a triangle (9) and station frequency memorized

Selecting the station. 1 Select tuner source Press the [SRC] button. Select the "TUnE" display. 2 Select the band Press the [FM] or [AM] button. Each time the [FM] button is pressed it switches between the FM1, FM2, and FM3 bands. 3 Tune up or down band Press the [4] or [¢] button. During reception of stereo stations the "ST" indicator is ON. 1 Select the band Press the [FM] or [AM] button. 2 Select the frequency to put in the memory Press the [4] or [¢] button. 3 Put the frequency in the memory Press the [#1] - [#6] button for at least 2 seconds. The preset number display blinks 1 time. On each band, 1 station can be put in the memory on each [#1] - [#6] button.

Headset says ringer off, cannot hear dial tone

A quick "get you started" guide.....

First set the squelch (gets rid of the hissing noise and allows the radio to scan)
to do this....

On the side are 2 buttons, the bottom one is monitor.
press and hold then look at the display,
turn the top dial until "AUTO" appears,

The squelch should now keep the radio quiet.

Now the tuning step..
You need to set this because if your radio was on 450.000 and you wanted to listen to 450.012.5 you would miss it if your radio was making 000.025 "steps". IE you would need 12.5 steps. This is the most common step used by ambulance etc in the UK, you will need to check local band plans.
Stick with 12.5 and you should get most stuff on VHF / UHF.
For airband 12.5 will get most stuff, but some is now changing to 8.33.
For HF (below) 136 Mhz I'd use 5

To set the step....

On the front there are 4 big buttons.
press [V/M.S.MW.SKIP] to select VFO mode,
then press [BAND.LOCK] to select the band you want to listen to,
then press [TS.SET] to enter the step
turn the dial to select your step (stick with 12.5 for now)
press [TS.SET] to exit back to VFO mode



To scan...

First set the scan type...
On the front there are 4 big buttons.
Press and hold the one that says [MODE.SCAN] for 2 seconds and look at the display,
turn the top dial until the screen reads ALL,
press [MODE.SCAN] again and the radio should start to scan with the 12.5 steps you set earlier.
If you want to change scan direction, just turn the top dial.
If you want to stop the scan, just press [MODE.SCAN].

When you hear something interesting, make a note of the frequency on the display.

To set memories (store frequencies).....

On the front there are 4 big buttons.
press [V/M.S.MW.SKIP] to select VFO mode,

to get close to the frequency you made a note of, press [BAND.LOCK]
Then set the actual frequency with the top dial,
press and hold [V/M.S.MW.SKIP] for 2 seconds to select memory write mode (1 short and 1 long beep)
turn the top dial to select which channel you would like to overwrite. Start with 01.
press [V/M.S.MW.SKIP] for 2 seconds. ( 3 beeps )

Thats it!

Any more problems just post on here and either me or someone else will help.

Should've asked more.. LOL.

Depends on a couple things.. I'll try to guide you as much as possible and if you have any question just let me know.

If you are running these subs on a ported enclosure or band pass, do you know the tuning frequency of the box? If it is sealed, I would assume it is 35 Hz + -5.

Also, can you select the frequency for the subs from the Head unit? If so, bring your HU's xover at 50-6- Hz. On the amp itself, turn the gain at 3/4 and you could either get the amp's xover at 50hz or below (that'll depend on your taste). the wiring of the woofer should be in parallel so that you can drop the impedance to 2 Ohms.

The band reject filter is for letting through "other" frequencies than the ones you have specified... which I see it as a good idea so leave it to off,
The band reject frequency, leave it at 40 Hz
Your woofer does great at low frequencies, so the bass boost frequency set it for 60-70 Hz.
Also, since you'll be using this for subs, make sure you have yout dial to LP (Low Pass/Through/Hi Pass)
The high pass dials you don't have to mess with as they aren't used on Low pass.

Something to note. If your stereo has Low Pass frequency adjustment, the amp will already be receiving only low frequencies, so, if you want to leave it in Through (or full) it will not matter, thus I had to admit that this Amp gives you room for seting the audio exactly as you want.

This will be the setting I would use according to my experience and my ear... but, it will depend on your taste as you'll be the one riding it.

if you have any question please let me know.

by the way, hopefully this was useful to you
