That's a massive win! Enjoy.

Yeah, except these AT-6666 PRO / QT-80 radio's don't have a power up display at all. (The AT-5555N2 and QT60 / PRO have the configurable display text, but that is programmed with the PC software, and is not stored in the firmware either).

I would guess the guy who owned it knows what happend. And maybe roughly how he let he smoke out! haha. If it was a random failure, then the radio should still be under GPE warranty, but maybe it is not transferable? I hope you can get a good result.

My guess is it has blown finals or something else in the PA stage, causing a large current draw (or, large voltage drop) on TX, which causes the radio to reset. That's just a wild guess though. Did your friend mess with the service menu? As a very long shot, also try another power cable on the...

What do you mean by "display name"? The name shown in the QXCodePro3 firmware tool, or something else?

Not yet. But they will be soon.

Ah - ships in the night. Good you have it sorted. The factory does not want to release the v2.05 on its own (yet), because the 90% of users who don't upgrade can't use v2.05 and will have trouble. It was done on purpose. (The idea is that if you are smart enough to upgrade the firmware, you...

1 - Download the entire RAR file again from the website. 2 - Extract into a new location. 3 - Try the process again (and don't move the files around, I notice that you have the H and DSP files in the same folder. This is not how they come, they are supposed to be in their own folders. There...

TXNR is turned OFF on the radio itself, by pressing the NRC button while holding PTT (during TX). So, it can be set independent of RXNR.

Ha! Good catch! Next time it's updated, this will be fixed

Hi all, The new AT-6666 PRO firmware update V1.01, and the new PC Alignment Tool are available for download on the AnyTone website now. https://www.anytone.net/download 73

All CW changes are in the changelog. If it's not written there, it has not been changed in the V1.01 update. 73

Good stuff! The bands are in pretty good shape. Have fun!

The difference is it might not work for you, because the T-R delay is a obviously important for the way you operate CW. It does work for me, because I send pretty slow and because of this I can work around a delay with no problem. But to each their own. Just get the new FW when it comes out and...

There is always going to be a CW TX key-up delay in this radio due to hardware limits, so if you are a very serious CW operator, you probably will never love it. (CW was added to the PRO as a bonus mode, it was not designed for it originally). But for casual CW use, this update is a huge...

The QT40/ARES 2 does this when the resistance on the PTT line is higher than it should be. Try some contact cleaner on the PTT switch, and the UP/DN buttons. If it still has the issue, it is likely that the wiring in the curly cord is adding to the issue. A new MIC will almost always fix the...

Many. As mentioned in the original post (changelog). 73
