That¡¯s hard to tell. Probably nothing damaged if you are still able to transmit on all bands as expected. I know the concern. But if it¡¯s working normally, it¡¯s not like you¡¯ve partially hurt something. If you ruined the finals you¡¯d be putting out nothing or milli watts. Have you made any SSB contacts or listened to yourself on kiwi sdr or web sdr? Do you have a power meter and dummy load to test output? Hopefully someone else will have a better answer or suggestion.
Today I was racing the bands so much during a POTA activation that I noticed I CQ'd two times 5 W in FT8?on 6 m using the wrong output (antenna was in the rear but the menu was selected FRONT). After I noticed, I corrected and the radio operated normally on both outputs (apparently).
How much did I ruin the radio??

You are right. I was mistaken. I thought blinking only works with a built-in battery only. I just checked out, the indicator switches from none to blinking, with external power with a voltage less than ~11.5V.

Not really. Blinking indicator means the radio produces 5W, but voltage is less than ~11V. This works with a built-in battery only. With the external battery there is no blinking indicator at all, the 5W output with indicator disappeared or 2.5W with solid three bars only. Therefore you can get 5W with voltage less than ~11V from built-in battery (blinking indicator), but you cannot get 5W from external battery with less than ~11V (no disappeared or blinking indicators, three bars or less only).

Following Blasco's advice, today I used a Powerwerx meter:
?
With Bioenno (LIII not blinking but with all 9 bars from PO indicator lit):
RX: 0.35 A, 13.06 V, 4.7 W
TX: 2.3 A, 12.90 V, 29.6 W
?
Screen:
RX: 13.0 V
TX: 12.1 V
?
With Windcamp:
Screen:
RX: 11.0 V
TX: 9.9 V (from this voltage on, the LIII icon was able to blink)
Regardless of blinking, all 9 bars from the PO indicator were lit.
?
The behaviour seems contrary to what Serguei said, but in accordance with what Andy said.

Michael, The damage that can be done to the FT-8xx series of radios is why Yaesu recommended to the HAM RADIO DELUXE folks to remove the capability to read/write to that same area. The later versions of HRD no longer R/W to those memory locations. So consider the benefit opposed to the final cost.
It's your rig, use it the way you like.

I've seen a price in Europe of 999 euro ......another hop says
9999 euro.
It can be ordered for 999 at the specific sellers store.
Will be available early 2025

Hi Dave
A google search shows Gigaparts it can be reserved for $35.00
but that is all I see right now. The picture in that ad shows a
nice looking rig. Not sure I need another rig right now so I
probable wouldn't be interested myself but a trip down to see it
in person might be fun. I'll wait until it is offered for sale
to see.
Good luck though.

Supposed to be coming in February the last I heard. This is, so far, the least publicized radio I have ever seen.

This only means the voltage (not power) of your Bioenno battery is not high enough to allow 5W output mode.
When a battery voltage is greater than ~ 11.5 volts the 5W output is enabled, when a battery voltage is less than ~ 11.5 volts, the 5W output is disabled. It does nothing with a battery capacity, only with a voltage.

Hello,
If I use a Windcamp 3 Ah battery, I can choose the power among the values LI, LII, LIII and LIII (blinking). If I turn off the windcamp switch and plug in a 9 Ah Bioenno, I can only choose among LI, LII and LIII. Does it mean that with the Bioenno I can only output?2.5 W?

Removal of that +Vcc is the final step the sequencer performs when switching to transmit, and the first signal to be output when switching back to receive.

I do exactly the same on one of my 10GHz rigs. If I remember correctly, I have a ~1k current limiter resistor in series between the +Vcc and the TxInh pin.

Hi David.....i'm following up a very old post you made back in 2016. TX inhibit on an FT817. Did you get to the bottom of it? Does it work? It looks like placing 12v on the TX Inhibit pin on the ACC socket prevents RF being transmitted. I am working on the sequencing for my 10Ghz system and a TX Inhibit would be very useful!
Thanks, best wishes ...and Happy New Year

Hi Andrew,
?
I may help here... My radio is FT-817ND and the plan is to use it as an IF rig for a 10 GHz station. Of course, I needed a sequencer and decided to design and make it myself. Using the inhibitor was part of this design. It allows to control the TX of the station by the PTT button of the radio mic. You press PTT, the sequencer can sense it, but no RF goes out of the rig until the sequencer makes the necessary switches. After it does and deems it to be safe, it lets the RF go. All this is possible due to controlling the inhibitor line.
?
In my case, I use a 47K resistor to pull the Inhibitor line to the 13.8V point (also available on the same connector). This prevents generating any RF by default. When it is time to transmit, the inhibitor pin is connected to the ground.?
?
I did testing using a power meter and it appears to be working pretty well.
