Thanks for the ideas and working it into the design!?
It's nice to see there's enough programming space available to build-in these kind of creature comforts!

So the ~AUD400 asking price was a bit of a shock. I guess I was thinking more along the lines of other optical products and maybe something like a ~AUD100 cost which might almost make it an impulse purchase. Not this time.

Yes, the FLIR camera isn't cheap.? That's why I had to find an "around the house" way to use the camera, to avoid overly-annoying my wife! (although in fairness, she really doesn't complain much about my expensive hobby.)

But I do see some US$50-$100 IR cameras on aliexpress, and even a $150 one on Amazon.? I have no idea if they work as advertised or are complete crap.

Are there RF Filter Sweep screen shots for 80-20m posted some place?

Paul,

The home page shows a 40m scan. Hans posted that with no comment, presumably acceptable.

Many people have included scans in their posts better than that and expressed dissatisfaction. I'm not sure what to aim for, some have fiddled with the coil spacing and capacitors to make the traces look good. Maybe they improve performance, I'm not sure anyone has proof.

Al, I had the same experience with the Nino TNC except it used multiple LEDs of different colors and at night it lit up my house like a disco.? Even worse, the LEDs used a resistor array so I couldn't easily solder in higher value resistors. In the end I added a switch on the array's ground to turn it off if I wasn't troubleshooting the radio's link.?

If Hans doesn't get around to it, add a potentiometer or resistor in series to your LED.

Joshua?

I have some really cheap LEDs from China. I think they were $3 for 100pcs in assorted colors including shipping. They are really dim. I just swapped one in. You could also lift a leg and add a resistor.

I'm interested what was the FW you used when you rung those measurements. I think Hans fix this issue in the last one (1.05 I believe). So please check.

My QDX firmware is v1_05, and the board is PCB Rev 4.? AFAIK this is all the latest, I ordered it in late October and received it from Hans the beginning of November.? I built it on Nov 5.

About the FSK issue, I would like to try repeating the tests using a longer QDX frequency measurement period than the default 100 per second.? With the WSPR symbol rate being so slow there's no reason that it couldn't measure more audio cycles and get a more precise frequency measurement.? That way we could tell if the error is due to the measurement, or to the S15351 divider setting algorithm.? (Although I believe that Hans already knows which is the case, likely the divider setting).? Certainly the default frequency measurement method *should* provide far better accuracy that my measurements were showing.

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 some. Maybe something like the backlighting feature in U3S with stepped decreases, but never totally out.?

Thanking you in advance!

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.

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

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

Hans -

Any idea when the new band version will be available?
