Yaesu memory programming - skip vs. select vs. off/blank? FTM-100/400 series

It seems on at least the FTM-400 series, there is a use for this. You can set the scan mode to "all mem" or "select mem": in "all mem" mode, the radio will scan all of the programmed channels, ...

Airband Jammed on Yaesu VX-6R

My experience, with a VX-5R, is that its AM receiver just isn't very good. It will switch into AM mode when you tune into the air band, but because it's really an FM radio, there is no AGC on the AM. ...

Where is the speaker on the Yaesu FT-857D?

I don't have one handy to validate this, but in the manual you can see the speaker grille on top of the radio in the angled view on page 20. This is the same place it is on my FT-897. So, yes, the ...
