Re: Why is wideband VHF coverage only to 154MHz?
|
For a backpack radio yes it would be nice for it to go above 154, go at least to 163 so it could receive the weather channels.? If someone is out in the boonies monitoring the weather would be needed.? But Yaesu chose not to let the FT817 go up into this range.? Why, I have no idea.
And many of Yaesu's HTs cover the air craft band in AM mode.? FM HTs having AM.? The FT817/8 has AM for all bands.

Or, if you really want to listen in that extended frequency range, get an FT-857D. It isn't all that much bigger than an FT-817, covers that range and has features the FT-817 doesn't have. I find the DSP very useful.

Sure,
Environment Canada also has Weather Radio Canada in that range. It's
also the Shore Transmit range for Marine VHF and near to North American
rail frequencies. None of these mean there'd be any need to include them
in a ham rig.
So, Why: it's 1. a ham rig, 2. designed to replace the FT-690, FT-290,
FT-790 -- no need to include anything other than ham radio coverage.,
and lastly, designed in a country, for a world, that has no NOAA/Wx Rdo
Can (other CANUS.)
If you need/want it on/with one radio, try a converter. There used to be
the MFJ-313 VHF Converter. The schematic for the MFJ one is in the Files
area for this list. There are other possibilities to acquiring one,
having one made, making it oneself.
