Hi all I have had this flexradio 1500 for 14 years and just last week it developed a 2 tone noise on transmit that I can see on the waterfall it's about 1/4 as strong as the overall signal. It is in the same place that the 2 tone test signal would show up at when using it for testing. please help it is annoying to contacts when the band is quiet.
Thank you Kevin N7AND.

Rich Text Editor. To edit a paragraph's style, hit tab to get to the paragraph menu. From there you will be able to pick one style. Nothing defaults to paragraph. An inline formatting menu will show up when you select text. Hit tab to get into that menu. Some elements, such as rich link embeds, images, loading indicators, and error messages may get inserted into the editor. You may navigate to these using the arrow keys inside of the editor and delete them with the delete or backspace key.
