Hello Bill It's going to take about 2 weeks until I get the toroids and capacitors from US. There's no other manufacturing because the PCB is the same. Just parts. 73 Hans G0UPL http://qrp-labs.com

Hans, Something to put on the list of "wouldn't it be nice" items for future releases of firmware. Yes, it's very eye catching in it's present state. But, it would be nice to be able to tone it down

Thanks, Bruce. On my setup, I run the QDX at 7.5V and the HR-50 at 11.5V to get the bands I'm on (40 - 15m) all around 30 - 35 Watts. -- Dan? W6AZI

Every time I go to try to install and test JTDX I seem to get frustrated, so I haven't gone there yet. -- Mitch, AB4MW Sent with [Proton Mail](https://proton.me/) secure email.

Thanks, Mike. You can still buy new roller inductors from Palstar: https://www.palstar.com/en/inductors/ -- Dan? W6AZI

pull the power and then plug it back in -- Mitch, AB4MW Sent with [Proton Mail](https://proton.me/) secure email.

I run into that problem on my 7300 also.? What do you mean by power cycleing the QDX? Thanks. Andrew K6STN

Hans - Any idea when the new band version will be available? Bill - N2OII

Mitch, I know what you mean about "normal," I've had the same experience with WJST and having to boost levels in QDX, especially 20m. For now I'm just leaving QDX levels about at the default and

That sounds like a normal change to me. Remember, each "band" is a different audio level setting. The ambient activity will raise the overall level in my experience, so if a lot of QRM/N and a lot of

It's a lot easier to just use the Sound Control Panel. [image.png] -- Mitch, AB4MW Sent with [Proton Mail](https://proton.me/) secure email.

Thanks for the post and pic, Dan. I too have had great success with HR-50 and its antenna tuner.? I have experimented with lowering the voltage on my 12 v QDX to ~ 7 volts, and this results in a

Nice, thanks for documenting (and sharing the stl file)! 73, Willie N1JBJ

Attention: This modification applies to boards Rev1 and Rev2 only! If you happen to own a QDX Rev3 or newer you don't need to retrofit, since your QDX already offers PTT output. After many happy QSOs

Nathan, Is 5 volts present on the main board? I can not see how it could be missing because the 5 volt line goes to other places. Look for bad joints on pin 11 on both boards. Is pin 11 truly

Thank you, Cliff. I have corrected that, since Ken G4APB showed me how to set the audio level in the QDX.

Hi Paul, Thanks for sharing your measurements. I also have some thermal measurements (look after my previous messages on this group) that shows T1 and diodes as a principal heating source on transmit
