ok so i got my radio and antenna set up in the car the swr seems to be fine, the radio is a superstar 3900 i decided to test it by going on to 27.555 and tuning my scanner to the same frequency my scanner was inside and i was out side in the car the only thing that the person inside could hear was a kinda wineing sound, is there a better way i could test this befor i go out and about, i just got this radio from ebay and now im unsure if it works also the neddle dosnt move when i transmite on usb only seems to move on fm, im confused as to what to do could i have got a duff radio?

i can only help you on the needle not moving as i am new to this hobby myself, key your mic and whistle or speak into it, you will find the S meter (needle) will move, if not you may have a problem.

Hi, all may not be lost

The whinning, could be feedback, or too much recieve RF soooo close.

Also your needle wont move on SSB unless you talk into it

You see with FM, for instance, when you transmit you get a carrier radio wave (which is fairly constant) which is effectively your output. But with single side band (LSB=Lower Side Band, USB = Upper Side Band) its different. Your voice is, effectively, the carrier and there is no output except your modulation (Your speaking).

1/ Make sure your set up, radio and aerial, is checked for SWR, see other threads here for how to do this, but this needs to be done using FM/AM with an SWR meter.

2/ Make sure your reciever is well out of ear shot and a good distance away from your tranmitter, on the same frequency and mode (FM, USB, LSB etc.)

3/ Test You may need to fine tune your recieve frequency, sometimes called a clarifier, so you dont sound like pinky and perky or the big bad wolf

Sorry if I'm not to clear, but I'm sure any questions can be answered better by others

Does your scanner have USB? if you were trying to listen on FM but transmitting using USB that might explain the problem..
