Yaesu fl2100b band switch locations

Connect a dummy load and try it using the manual setting on the ATU .

Almost always a programming issue. Somehow, the transmit frequency is not enabled or programmed correctly. Always include all the zeros when programming these. The decimal point is critical also.

This should help you..

most yaesu transceivers are not capable of tunning the wide band FM broadcast band needed to hook up sirus or delphi satellite radio

I would flash it back to the older version. Double check you have the correct firmware. This almost sounds like the incorrect version for your radio.

Not having the panel in front of me to look at, I cant be positive but it sounds like the selector knob itself may be out of position, as well as the switch may have come loose and rotated in position and was tightened in the wrong place.

There is probably an internal fuse which has blown. Send it to the Yaesu service center for repair. They're reasonable and will do good work...

has it been opened up to talk on

The FT-1802 is a 50 watt 2 meter FM transceiver. It can transmit anywhere between 144 - 148 Mhz (the FM portion) of the 2 meter ham band. It can receive anywhere between 136 - 174 Mhz without any modifications. There is a modification to enable transmit "out of band" below:

There are few details about the results of this mod - typically these provide for transmitting on frequencies outside (above, below or both) of the 2 meter ham band. Transmitting outside of the ham band without a proper license for the frequencies in the U.S. is a violation of FCC rules.

Your radio has not been modified to transmit outside of the amateur bands.
