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

Hi all, I have just posted an update on a new AT-6666 PRO firmware update, PC Alignment (service mode) tool, and PC software here: https://www.worldwidedx.com/threads/at-6666-pro-update-firmware-pc-alignment-tool-pc-software.268861/ 73, Pez

Hello all, AnyTone will be adding a new a new radio firmware update V1.01, a new PC Alignment (service mode) software tool V1.02, and new PC Programming software V2.05 for the AT-6666 PRO, on their website soon. This will all be available in a few days at https://www.anytone.net/download PC...

You can check SWR in SSB mode, or in any mode for that matter. However the SWR meters ability to respond correctly the the rapid changing amplitude in SSB is the main limitation. One way to test SWR in SSB mode on almost any meter (cheap or expensive), is to transmit a constant audio tone...

Welcome! :) I would try a different antenna if you can also. Mag mounts are often bad news, they can cause all sorts of issues with common mode current, poor grounding (even when it tests ok with a multimeter), etc. Hopefully you will end up with 2 good radios. You can't ever have too many...

It could have had the service menu messed with - potentially causing a PA / oscillation problem to occur due to incorrect bias settings, or by the incorrect adjustment of other settings relating to the TX stage. Returned radio's that have have the service menu messed with are a big problem...

It is happening. And it will be available soon, along with new firmware to support it. 73

20Hz is annoying on SSB when it can be better than that. A solution is very close, which includes the reference oscillator adjustment. 73

Thanks for the info. That is an interesting one. What does the LCD report as the SWR value when this occurs? Does the displayed SWR peak higher than it should with modulation, and drop again without modulation, or does it "hang" (maybe indicating self oscillation). Also, can you try a different...

I have used RM Noise with a Hermes Lite 2, with Thetis. It's performance is actually amazing. I have almost zero noise floor at my QTH anyway, but the ability for RM to pull signals from below the noise floor is incredible. The only "annoyance" for me is the round trip processing delay, and the...

Good stuff. The TX bandwidth setting applies to SSB only. See "TONE" in the menu. You can see set result, on a LSB transmission here: https://www.worldwidedx.com/threads/anytone-at-6666-pro.268405/post-844461 73

I have the TF930 and I love mine! I prefer it over a HP that I have. I reference mine to a GPSDO. I added a 10MHz BNC input to the rear panel, for neatness, and I use the front as a 10MHz output if I need another 10MHz source. It has a built-in battery for portable use (I never use it...
