hello i am new in the forum. I can not hear the frequencies in vfo mode, there is no voice only noise when it stops in a frequency after holding scan button. How can i set up my baofeng without the programing cable? y want to scan the frequencies in vfo mode holding scan button, in some freq the green led is on but i hear only noise and no voice from anyone, can you explain how to use it, i have no contact with a ht until now. Thanks a lot...
