Re: TX ERR on 40m from .101 to .200
Thanks Nick for the trick. I downloaded his software. But that widely opens the 817, not only the second part of the 40m Band (or the 60m Band).?
Is there another kind to open just our ham’s bands ?

Re: TX ERR on 40m from .101 to .200
Try a search for "M0BMN widebander". That was the software I used to use to unlock coverage for 60 meter operation.

FT817 over-currents in tx on 18Mhz (17m) and 21Mhz (15m) - any ideas?
HI all,?
I am trying to repair an early model FT817. It is fine on all bands/modes in RX.?It is fine on TX in all modes, except for 18Mhz (17m) and 21Mhz (15m).?
In the affected bands, measured in CW, the rig draws 3A+ from the bench psu, and RF filter relays buzz loudly. This can trigger a shutdown, or the rig stays on and buzzes terribly.?
?
My analysis so far - testing in CW mode: the preamp/driver stage works well. This feeds into the PA finals board, which seems to amplify happily - but supplies too much current in the affected bands. If I separate the predrivers/PA final stage from the RF filtering stage at the balun (T3001 in schematics), and insert a dummy load to absorb the PA final output, the TX works normally (~2A PSU current draw) on ALL BANDS.?
?
This suggests the issue is the balun itself or after the balun in the RF filtering stages.?
?
According to KA7OEI's fantastic info pages, , 20m & 17m use the same RF filter FIL5, while 15m, 12m & 10m all use FIL6. Given 20m and 12m/10m work ok, this suggests the issue is not in the RF filters themselves, since they work happily 'half the time'.
?
Through experimentation, I notice that reconnecting the balun (T3001) to the RF filter board via an inductor of ~0.3uH (originally discovered after using basic crocodile clip cables to reconnect the stages together), the TX over-current stops - and the rig operates as normal, except for the introduced inductance that rises with frequency, hence lowering the output power (and lowering the PSU current draw) with rising TX frequency. This 'fix' itself causes problems on 50+VHF/UHF I think.
?
It suggests to me there is some low impedance path to ground around 20Mhz (affecting 18Mhz & 21Mhz), and have pulled the board out of the rig to take a look. But nothing seems immediately wrong.?
?
Has anyone experienced similar TX over-current on specific bands, where other bands work fine ? Could the issues lie in the RF filters? How best to test balun T3001 to check if it is at fault?
?
Any ideas or suggestions are greatly appreciated,?

Re: Ft817 shuts off at 10 volts?
The Windcamp battery also works below 10v.
Or, it's tired. May need a new one.

Re: TX ERR on 40m from .101 to .200
Hi all, sorry to undig this topic but I'm testing a FT-817 for a friend and saw that exact problem : TX ERR above 7.100 kHz. Could someone gives me a start point, as the previous pdf link is not available anymore ?
Thx, 73 Ben - ON5BGO

Hello,
I'm using a generic CAT bluetooth device paired with a DIN/P2 cable connected to FT8CN for an FT8 interface. Out of whim, once or twice, if I TX at 5 W on 10 m, the ALC goes to 0. If I change the power to 2.5 W (only change I make on the rig), ALC goes to "4 bars".?After a couple?of TX's in this configuration if I change the power back to 5 W, ALC stays at "4 bars" permanently.
Any suggestions what might be causing it?

Re: Ft817 shuts off at 10 volts?
Just a thought - if the battery has an integrated BMS then it may be that that's cutting out rather than the radio.?

Re: Ft817 shuts off at 10 volts?
Just to add that it's best to measure the voltage at the dc connector so as to take into account any voltage drop in the power lead.
Also IIRC Yaesu recommend using 13.8v as input if calibrating the voltage parameter,? it's in the service manual I think.

Re: Ft817 shuts off at 10 volts?
The radio will work below 10v, the stock NiMh pack is 9.6v, you usually won't get full power at that voltage. There is a volt meter calibration in the service menu. I have done this, as in measure the battery with a DVM, then turn on the rig and correct what it displays. So there is a chance your battery is very low, but falsely displaying 10v.
The Radio or the battery??

I thought 11 volts was the minimum it would work at.

Hello group! I recently bought a non- ND model Yaesu Ft817 that has the Windcamp 3000mah battery installed. I can charge the battery up to 12v but, once voltage drops down to around 10v the rig shuts off. Is this normal? Any help would be greatly appreciated. 72 Mike

Re: Ft817 shuts off at 10 volts?
I did a POTA activation for probably 1 hour of transmission time before it shut off. Possible a little more? Can’t remember for sure the exact time. Thanks

Re: Ft817 shuts off at 10 volts?
Yes, I think that's normal. I have the exact same radio and setup, but with a new Windcamp setup. I've yet to deplete it, but haven't used it much . Maybe the older windcamp battery is just tired, or you are just using it up. How long before it drops to the 10v shutoff point??

Re: Chirp issues? Old 817. Distant stories of bricks
I have used the Bob Freeth G4HFQ program available at?https://www.m0lxq.com/g4hfq/download.html There are also programmes available for several other Yaesu radios; I use the 7900 & 8900 versions also.? There is a PDF document associated with the programmes which has the passwords to activate the software for life.

Re: Chirp issues? Old 817. Distant stories of bricks
I have used CHIRP for programming for many years.? I have used it for FT817, FT818, FT70D and UV5R radios of my own and two or three for other people.? I also mentored others doing it themselves.? I am convinced that the radios I worked with could not have been bricked.? It is likely that something was done during the upload (i.e. intermittent power or an bad entry in the data) that caused the radio to go stupid.? Every time that occurred, a factory reset fixed it.? That is why I tell everyone who asks, make sure you have a copy of the radio saved so you can get back to the state before you attempted to program.? I also make sure they know the procedure for their radio to be factory reset.? When I have heard people tell me their radio was bricked, I ask a few questions and find that the radio just wasn't acting as they thought so they called it "bricked" and sent it back for repair.? I find CHIRP to be a powerful utility for using programmable radios.? I recommend it for your use.

Re: Chirp issues? Old 817. Distant stories of bricks
Hi Marco
I have to agree at least to the fact that I also use CHIRP and also have YAESU radios that I have copied the memories from to keep as a backup and restore or clone. Recently also have copied some memories from the stored image to a Retavis GMRS radio. No problems so far and that is many years. Mainly because other software developers refuse to provide their software to work in Linux. Maybe as you suggest it is on Yaesu.

From time to time I've been asked to support other features which would have required "peek and poke" undocumented CAT commands (which BTW other programming softwares use to work with 8x7 radios) and I refused as, believe me, using those commands you can really and easilly brick radios.
More, I've never been able to brick my beloved 817ND in a way that a restore of the backup from CHIRP itself have resuscitated it (not even during first stage of module development) but if it should ever happen I just would have said to YAESU that "I was following instruction in manual page 69 of the operating manual and i get it bricked".
I'm really sorry you believe your 817ND have been bricked by CHIRP (or any other sw) but we have to point our finger to YAESU itself because if any radio can be bricked via the software programming interface, it’s a radio bug.
All that said if anyone is happy using any software (paid or not) I wont argue but for those of us using non-Windows platforms Chirp is the only radio programming software that runs on Macintosh or Linux at least as far as I can tell.

I have sence used RT Systems's ADMS-4A
for programming my 817ND.
In fact, I now use RT Systems software for ALL 6 of my radios.
It is only $25.00, for lifetime use and full support and updates. If you need a programming cable with the software, it is $49.00.
Others have used CHIRO with little or no problems, but it is use at your own risk.
I myself, do not want to take anymore risks with expensive radios.
Anyway, that is my experience with CHIRP.
