I lost my AM frequency. FM is working. What can be wrong?

FM only works with an antenna, (any) and one came with it new in the box, lost it?
AM works due to build in antenna. (loop stick device)
FM no shuck device, like BOOM box ever see that whip antenna
that is FM (I am Extra class HAM) and know my antenna's well.

find the mode button and press it
the different frequencies will come up as --am,fm 1, fm 2, fm 3, etc and from there you can select the different stations in that fm range

fm frequencies are just that fm frequencies ( not japanese, chinese ,english or anything else
it is a range of frequencies in the fm band that local stations broadcast on
so all you have to do is to turn the tuner knob until you get 107 fm
so as you turn the knob you will loose 89 and it will go probably 90.5 , 100.20, 102.7 etc and if there is a station broadcasting that your radio will pick up it will come in and then fade out as you keep moving the knob
you may have to change the mode as there are fm 1 ,fm 2,fm 3 bands to get your fm 107 as it will depend on what megahertz 107 is operating on

Select free channel or frequency on your radio and align it with the one on fm modulator depending on the type of radio used. Make sure the modulator has the power on. Does the cigarette lighter work, if not check it. make sure the radio receiver/ transmitter component or antenna connected as this need frequency to produce sound like a radio.

think u need a radio made for europe--or ud have to physically alter the circuit--dealer wud know

1. Search strong FM stereo station. (Like 97.05Mhz instead of 97.00Mhz)
2. Turn off auto scan/FM mode.
3. Adjust the frequency to 97.00Mhz
4.Adjust the Filter T01 very gently (about 5 degrees clockwise) as to make the Quartz lock lamp light up.
5.Turn on auto scan/FM mode and check for FM stereo lamp

You are going to have to buy a local radio from a junk yard or an after-market radio. The frequency range for broadcast radio is different in Japan than it is in the US (88 Mega Hertz to 108 Megahertz) in the US and 76 to 90 MHz in Japan. There is a device called a frequency range expander and you can find them on ebay sometimes but no assurances how well it will work.

it is how to get a japanese car working in the UK but you will get the idea.

All that means is to put your radio on FM 88.1, and just wait. Jabra will find the exact frequency (mine is 88.7) and then it will work. When you want to use it to listen to music, just put the radio on 88.1 .

it might be that your gadget posses a wrong panel written AM when there is no am tuner. If you can check inside it whether it has a choke wound with copper wire for AM reception. If its missing, its aint gonna have any reception
