    I did everything that expert recommend me, before his answer. Its not working, thats why I ask for everybody: can somebody recommend me, where I can see all parameters (possible diapasons) of my radio, because my previously radio hadn't these problem? I need advise from people who knows this model.

All modern radio's use phase lock lope, if u have a problem receiving a particular frequency there is no adjustment for this, u do the following, make sure you have a proper ground for the antenna to the chassis of the car and that the antenna coax is withing ohm out specs, the signal ground is the usual problem, verify it is less than 3 ohms to the sheet metal of the car. Remember different radio receiver's vary in the channels they will receive, for instance in one system you might get a particular station well, install a diff radio receiver and that may not be the case, these are normal differences between units, no mystery to it.

Hi,

AM runs from 535 kHz to 1,605 kHz. It is in Medium Frequency range which ranges from 300 kHz to 3,000 kHz.

FM runs from 88 MHz to 108 MHz. It is in the VHF (Very High Frequency) range. VHF is from 30 MHz to 300 MHz.

Absolutely, your device must be able to get AM: 630 since it is in the range. Your problem might lie in the fact that your device is set to "AUTO-TUNE". Therefore, as you scan the amplitudes, it scans those that are previously captured (stored) and jumps one setting off. Try the following:

While you're in the location where AM 630 is negotiable with your device, try "Seek Tuning" OR Scan for tuning and save the results. If AM 630 is not negotiable in your location yet, try to set your tuning settings to manual mode and just set it to 630.

Regards!

Model 170 with a Kawasaki 14 hp engine. Why doesn't anything happen when I turn the key?


This is a 12 volt system and the battery should have 12 1/2 volts. Motor running the voltage should be above 13 volts and below 14.5 volts. You will need a battery charge or jump start.

How do I preset the tuner for radio stations. I've never had a problem doing this with any other stereo. But what I think should work isn't!


Not very specific. Do you have the manual?

The following is from a VSX-03TXH manual. It ain't pretty but it may help.

I'm posting it in multiple parts due to space contraints.

Chapter 6:

Using the tuner

Listening to the radio

The following steps show you how to tune in to FM and

AM radio broadcasts using the automatic (search) and

manual (step) tuning functions. If you already know the

frequency of the station you want, see Tuning directly to a

station below. Once you are tuned to a station you can

memorize the frequency for recall later-see Saving

station presets below for more on how to do this.

1 Press the FM/AM button to select the tuner.

2 Use the FM/AM button to change the band (FM or

AM), if necessary.

Each press switches the band between FM and AM.

3 Tune to a station.

There are three ways to do this:

Automatic tuning

To search for stations in the currently selected band,

press and hold TUNE ?©/?? for about a second. The

receiver will start searching for the next station,

stopping when it has found one. Repeat to search for

other stations.

Manual tuning

To change the frequency one step at a time, press

TUNE ?©/??.

High speed tuning

Press and hold TUNE ?©/?? for high speed tuning.

Release the button at the frequency you want.

Improving FM stereo sound

If the TUNED or STEREO indicators don't light when

tuning to an FM station because the signal is weak, press

the MPX button to switch the receiver into mono

reception mode. This should improve the sound quality

and allow you to enjoy the broadcast.

Using Neural THX

This feature uses Neural Surround™, THX® technology to

achieve optimal surround sound from FM radio.

• While listening to FM radio, press AUTO/DIRECT for
Neural THX listening.

Not clear on how to search and store radio frequencies manually in my Kenwood kdc-bt6544u car audio player. can i jump to a specific time in audio or do i have to hold the FF or RW till i get there? not...


Some makers are different.Usually if you hold down the search button long enough,it will switch to autosearch.There should be numbered buttons on the face of the stereo too right?Tune in to the channel you want to preset,press and hold down the number you want it to be.The sound will probably cut out for a couple of seconds,then when it comes back on the channel is preset.Once you set 6 on FM,if you press the band button again,it should give you the capability of presetting 6 more.If it goes to AM just press band once more and it will give you 6 new FM.Usually current radios give 6 AM possible,and 3 separate bands of FM for a total of 18 FM possible.Good luck!

Go 730 not sending a fm signal


Hi,

If you have made a recent update this may be the reason you may have lost your FM transmission!!

Tom Tom disabled silent FM transmission on these units to comply with the law in certain countries which prohibit these FM transmissions. Later updates configured the units to output lower strength FM transmissions.

There is a possible workaround for this - see this link for a discussion on the issue.
http://www.tomtomforums.com/tomtom-go-630-720-720t-730-730t-740/19436-go-730-lost-fm-transmission-after-map-update.html

Hope this helps. Thanks for using FixYa

So I just had this exact problem about an hour ago. I wondered about the starter, crankshaft, etc. but discarded them for the simplest explanation: battery.
I'm sure you've all noticed how absurdly easy it is to mistakenly miss the steering lock and put the parking lights on. Odds are you may have done this without realizing (I must've even if I don't remember). Jumper cables are the answer.
If you've never jumped a bike, here's the skinny: 1) Make sure the car you're jumping from is, and remains, off. 2) Connect the cables as normal; black to black, red to red. 3) Let the bike sit for a minute then start her up. 4) If you can, take her for a ride to get the charge back up.
If this doesn't work, then you may very well have more serious issues. Hope this helps, ride safe!

Daytona 675 won't start


Hi,

Two possibilities:
  • starting relay. This could actually be bypassed/jumped to determine if the starter motor will turn:
  • starter motor. most likely carbon brush.
Just a start, do postback how things turned up or should you need additional information. Good luck and Thank you for using FixYa.

I think it recharges by taking some power from the computer when it is connected. I also use a cell phone charger from the razor series of phone.
