The LCD often shows “OFF” and the radio quits transmitting in VFO mode. Why ?
Check the LCD and see if the “+” or “-” icon is on; If the icon is on, most probably you are transmitting out of the ham band; The 222 MHz ham band is fairly narrow but still uses1.6MHz shift frequency as a default repeater offset. So if you are at 223.500 MHz for example, if you set 1.6MHz offset, you are going to transmit at 221.900 or 225.100MHz which are already out of the ham band. Press and hold the “F” key then press the “OFFSET” key right next to the LCD 1-2 times until “+” or “-” icon is gone. Release the “F” key and press “PTT”. Now your DJ-280T transmits simplex. We recommend you to store repeater frequencies in the memory and leave VFO mode without offset to avoid this problem. 10ch is not enough to cover the repeater frequencies. EJ-14U or 15U are available to expand memories to 50 or even 200ch at affordable Alinco prices!
