    We've noticed a huge increase in rants and negative posts that revolve around agencies going to encryption due to the broadcasting of scanner audio on the internet. It's now worn out and continues to be the same recycled rants. These rants hijack the threads and derail the conversation. They no longer have a place anywhere on this forum other than in the designated threads in the Rants forum in the Tavern.

Yaesu: FT-857D vfo scan in 2m FM does not stop

Not open for further replies.
Jan 14, 2017
Trying to figure out a frustrating problem with my FT-857D.
I am trying to do VFO scanning in 2m (144-148MHz) band. SQL/RF dial is set to SQL, the mode is FM, and TON (button A) in MFe is set to blank (ie, no tone encoding).
However, when I scan, the scan does not stop even if it picks up a frequency. The green light comes on, but the frequency keeps moving on. Even if I turn the SQL knob down, it keeps on going.
When I am not scanning, and just tuned into a freq, I can turn the squelch knob down and open the squelch as normal. But not when scanning.
In the 70cm band, on the other hand, everything is fine. Scanning stops on a signal and stays there for 5 seconds, as per the settings, and I can make the scan stop by turning down the SQL knob.
This behaviour still persists even after I do a [Home] [Pwr] reset.
Has anyone else had similar problems? Any suggestions?
