Any reason why the 817 only covers up to 154 MHz rather than 175 MHz?
All my other Yaesu VHF radios have 136 - 175 MHz RX ?
I guess there must have been a technical issue in going beyond 154 MHz RX?
Has anybody modded an 817 to provide RX up to 175 MHz?
|
One of the great frustration many US FT-817/818 owners have is that the receiver can not pick up the US National Weather Service VHF broadcasts, it is a hard limitation of the FT-817/818, the reason for which I can only speculate on. Ken, N2VIP

Has anybody modded an 817 to provide RX up to 175 MHz? 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. 73, John VA7OTC

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.

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.

Hi Group:
I understand how having a rig that will enable listening to WX radio would save weight while climbing and hiking... but for me, I would rather have a lightweight radio that can be dedicated to that function. ?For example, I have a Midland crank radio that includes a flashlight, AM band, FM band, and WX band. ?So it does multiple duty, and does not impinge on the battery power of the ham rig. ?I also have a Standard C108A HT which runs on two AA cells. ?For light weight and power capability I use lithium primary cells. ?This tiny HT weighs ounces, and receives Air band, WX band and 2M FM.
So I don't miss my 817 not having upper VHF coverage.

The Yaesu FT-817/818 is a magical collection of features and compromises, for everyone that says "if Yaesu just added this feature, it would be perfect" there are two people ready to proclaim "by adding this feature, Yaesu has ruined this radio!"
Honestly, I suspect (as others noted) that accommodating reception of one piece of spectrum (262 MHz, aka NWS in the US marketto satisfy a subset of the FT-817/818 owners in one market wasn't likely even up for discussion. As much as people like to complain about it, I don't know anyone chose not to buy the FT-817/817 because of the "limited" VHF RX coverage.

The 817 is clearly a fantastic radio...but presumably was there a technical reason for only providing wide RX coverage up to 154 MHz? Otherwise surely coverage up to 175 MHz RX would have been included? UHF coverage is 420 - 470MHz which is the usual UHF wide RX?

It is a legal amateur radio, not an illegal one! Even when you using the FT-817 for transverter-use, the frequency range should be more then adequate!
Why using an HAM-Radio out of the legal HAM-bands? I see no use for it! (144 to 146MHz in EU ; 144 to 148 in the U.S.)?
And, if it is so, in a case of an emergency, take your 'Bauwaufuang'- Radio, and do your 'illegal call'!?
What do you want to hear on the 'upper frequncies', other than 'no ham-radio' belonged stuff! For me, it is not that interessting! Allways the same, ... !?
It is for Ham-radio use, not for PMR or something else!?
And don't forget, the radio is about 22 years old, and still a 'hot shot' for some OM's/YL's!
No 'cheaper' allmode/allband radio, to buy until now, with a propper preformance! Other competitors are more expensive, or not as good as the trusty (rusty) old "Yaesu FT-817/ND/818".
Mine is more than 21 years old, with a second PA-board. (It was my own mistake! I forgot my battery-pack inside the radio!) and still going strong!?

He doesn't want to transmit, he wants just to receive with it. Most newer radios that I know of have coverage of the 162 MHz weather radio channels. My FT-857, FT-897 and VX-6R all receive in this band.
