I have a question about the digital signals I received today during what must have been an E skip opening to the southwest. <\/strong><\/p>\n

Can you identify by the bandwidth the wide signal in one screen capture vs. the normal FT8 signals which were decoding today quite well using the 7610?<\/strong><\/p>\n

Typical 6 meter band FT8 signals<\/p><\/div>\n

Wide digital signal on 6 meters.<\/p><\/div>\n

The wide signal didn\u2019t decode in FT8 mode, but I have no idea what mode was being transmitted. Any idea?<\/strong><\/p>\n

Great question, Rob. I’m posting this because I’m no expert on timed digital mode signals. I recognize FT8, and assume this could be FT4, JT65 or similar, but the timing is identical to FT8. I’m sure someone in the Post community will solve this signal mystery in very short order!<\/p>\n

Readers<\/strong>: Can you help Rob ID this wide, timed digital mode signal? If so, please comment!<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"
