Re: Power output instable
Pietro,
Does your display flash HSWR by any chance?? My 818 would do this from time to time.? I thought something was wrong with feedline, antenna or something else.? I examined everything.? As a last resort, I restored factory defaults and the problem went away.? It seems that software became corrupt due to a power connector and the outcome was the radio software misinterpreting the output power and SWR.? When the SWR becomes high (as sensed internally) the radio output is reduced.? Save your settings and memory (use CHIRP or some other software for memory) and reset to factory defaults.

Re: Power output instable
Does it do this on both front and rear outputs?

Re: Power output instable
It happens with any mode on 2m and on all other bands everything works.

I have a strange behavior on the 2 meter band, the output power (indicated by the display) is not constant when pressing the PTT.
Sometimes it reads 100%, sometimes 30%, sometimes 0. And actually the output power is different, it's not just the display. The SWR is slightly higher at low power, but not significantly.
It's not the antenna: I tried two, and one is a 70cm/2m dual band and on 70cm everything works great. It happens with any mode on 2m and on all other bands everything works.
I suspect a relay, but any tips on what to check would be appreciated.

Is QRP HF Mobile really a thing?
When I 1st got my FT-817 back in 2002, I was senior? field engineer for a global computer company in New England. I used to drive a Ford Escort hatchback, manual transmission. I think the only option on the car was remote control rear view mirrors and am-fm radio.. I was doing about 30,000 miles per year.? All though Rush Limbaugh was on the radio, you can't take 5 days in a row, as he repeates himself.
?
So having just received the FT-817 for Christmas, I decided that I could at least listen to HF while mobiling between clients. Some calls were 2-3 hours apart.? I added a ball mount by the left tail light and a ham stick for 40 meters.? The rig would sit between the bucket seats next to the? VW type emergency brake, right by my right thigh..
?
The hamstick was tuned to 7263kc. - ECARS - East Cars daily net. and Off I went... The rig was easy enough to throw in the trunk for safe keeping when in areas of New England, not so nice..
?
During the year, On ECARS I could always check in with net control usually in Pennsylvania and I in New Hampshire. I had buddies I could contact back in Virginia as I used to live there for a while. I later at a hamfest bought a 20M hamstick used for $10 and tried 20 meters.. one thing about New England Mobile- changing antennas -changing bands was a pain in the @$$ as roads are narrow, distances are limited and well pick a band and operate or just listen.. On 20 meters best DX was South Africa...
?
After 9 months or so the clutch finally went on that Ford escort at about 160K and so did the mobile operation as I moved to a new 4X4 Chevy Tracker, FT-100 and a Hi-Q antenna mounted at the back of the externally mounted spare tire. Wish I still had that setup. that 4X4 would get 30mpg, and during 50K warranty, never went back to the dealer.. ?
?
So mobile operation with a FT-817 can be accomplished, the only reason I went to the FT-100 was face plate separation and of course the Hi-Q all band antenna..??
?
My current mobile set up is a ICOM 7000 with a HA-4 remote tuner and I use a single 40M hustler for all band coverage... Even 6 meters...I've been using that 10 years now..
?
5 watts mobile is not impossible..? so the guy gives you a 5x5 instead of a 5x9... doesn't bother my ego...? Many time just listening is a thrill...

QRP is a compromise/challenging way to operate.
Mobile HF antennas are severe compromises.
QRP into mobile HF antenna in a vehicle in motion is compromise^2.
Parking a car and operating QRP with an antenna not attached to the vehicle isn't what I was thinking when I asked about QRP mobile, but I'll concede it's an undefined term.

I'm not saying it's horrible or unenjoyable, just not really
suited for some use cases of my concern. Anyhoo there are plenty
of aftermarket supports for the 705 for some reason. Activations
in civilizated places should be OK (POTA, BOTA or so). Activating
from the wild as an far away SOTA, not as much.

Re: Digital input sensitivity
Agree with Marco. Variable levels per mode.
The original poster, Pietro, referred to VHF as a band, and I phrased my answer to basically say "It will do what you want it to do between HF and VHF"
Mode-based levels have come in handy for me on both my 817nd and my 897d. DIG level on HF ssb, PKT level on VHF/UHF pkt pkt9600 mostly.

Re: Digital input sensitivity
The dig input level is the same for all band and is controlled by DIG MIC setting (menu #25).
I double checked with the internal memory map and it appear to have just one memory position for the each mic level by mode (ssb, am, fm, dig, pkt, pkt9600) so there's no way to have different level per band.

Mounting an FT817 is so easy it's hardly worth mentioning. Just use one or both cover screws located in four positions on the radio sides attached to angle brackets. Hardware stores carry angle braces which might need to be drilled, and you might need longer cover screws, but that's it.

Ahh--- being , "Made in Detroit" born and raised, I always loved the speculation every September when the new cars were "unveiled" and come the Detroit Auto Show 1st week of the year, the concept cars... The entire town was a buzz with comments both good and bad.?
?
That being said.. certain foo-phah's occurred, like the Motor Tend Car of the Year, that not a single unit was built.
?
However, no matter how modern and innovative the auto manufacturers were, the average Joe? still drove/ bought a mid-level auto that fit their needs, not the latest, greatest, can't wait for it under the Christmas tree item.
?
Given the banter expressed here this Sunday morning in Kansas, USA..? I had to comment..?
?
I hand carried a Yaesu FT-101 (30 pounds)? from NY to Shemya Island Alaska Air Force base at the end of the Aleutian Chain, literally so far west it was east.?? That was state of the art then. That was 50 years ago...
?
My point you wonder?
?
To my right as I type is my FT-991A... I think street price on a new one today is $1150 USD.. It has the same bands as FTX-1F, 100 watts adjustable, ( mine goes down to 5 watts on HF)? Weight 9.5 pounds (4.3 kg) and is 9 x 3.2 x 10 inches (229 x 80 x253 mm). All the features except a second receiver..
?
I submit that when the data is compiled regarding the FTX-1F - cost, the wait to buy one. Weight adding an antenna tuner battery and etc..(solar panel, computer, antenna even buying a back pack)... will the total weight and cash outlay be such that perhaps not having the newest fanciest flavor of radio (car) is a real advantage... plus-having a new learning curve to operate all the bells and whistles..
?
And I simply take my FT-991A on the road. As I suspect the weight difference may only be 2 pounds once all is said and done...I suspect the outlay for the FTX-1F will be more as well..
?
Like motorcyclists say, "Chrome won't get you home"
?
Now granted the FT-991A can do 100watts, but die hard QRPers, are rare that have never operated over 5 watts in their lifetime. I haven't used over 100 watts in 40 years...Don't need to. My homebrew antennas make my station.
?
Yes I have a FT-817 that was a Christmas gift in 2001... But these past few years it goes live only 5-8 times a year now... Many time I think I should sell everything but the FT-817 and a set of paddles.. buy a sail boat ...get back to "real ham radio"...
?
ahhhh? someday.... I'm only 75....got plenty of time...
?
Enjoy this fall season and band conditions. After 58 years of being licensed, Amateur radio still sparks a daily enjoyment for me..?? it's so diverse...that is it's allure.

I think it looks like a good little radio and I’m quite excited about it.? The aftermarket will come up with protective rails/cages very quickly, in fact I will probably have detailed measurements in the email to my buddy in Portugal within hours of receiving the radio and a prototype on my doorstep three of four days later. Final product within two weeks.? It would have been nice to have in a waterproof variant, but no big deal. I only have one waterproof radio and it was built by Harris and would have cost the GDP of a small island nation. Those sorts of radio are out of reach of most hams and truthfully it’s not a very good ham radio anyway. It’s fine for a military radio or just sitting in one frequency calling CQ Pota. But no vfo function, so not the best.? I’m (as I said) quite excited about this upcoming radio and can’t wait to get one…the trick will be coming up with the money for it.?

New technology uses more power than the turn-of-the-century technology in the FT-817/818, so the low-power consumption ship has sailed, for example...
The radios you describe had minimal info to display, so they could get away with minimal front panels (a meter and a seven segment channel display, for example on a CB), but modern radios are expected to have things like band scopes and waterfall displays, something that's all but impossible in the FT-817/818 form-factor.
The IC-705 has a similar shape, and plenty of after-market cages and lids to protect them have come to market, I see no reason the Yaesu after-market vendors won't do the same for the new FTX-1 Field radio.
You are literally rejecting the radio because of its shape, nothing more - amazing.
Tell you what, why not take the radio, it's ATU, and it's battery pack and then get a really big piece of heat shrink tubing and make it the radio you want it to be - a rectangular box with a conventional face... if you did that, I suspect it wouldn't be long before you complain about weight, and once that's addressed, I suspect power consumption will be the next thing you complain about.
