There hasn't been any change to the TX RX commands. And I'm using 1_08 with JS8call without issues. So I suspect you have some other problem...

Re: QDX pairs nicely with the Micro PA50
This would make a great amp but unfortunately it does not cover the whole 10m band. Not a good idea to stop at 28,5 MHz. ? Robert, OE7OER ? ? ? James,
Here is the link:?
You can manually change the band prior to key up if needed. Push the button 3 times successively.
A manual knob for band selections is what my MX-P50M has.
I did a quick check with a 3.5mm TRS cable with the IC705 and am finding strange behavior of the amp. I will need to do a bit more testing.

Sharing QDX repair experience
Hi folks -?
Sharing this repair experience in case it helps others or if anyone has further advice to add.
After a couple of days working fine on 20m and 40m my QDX stopped transmitting and battery current on receive went up from 140mA->320mA. Reading Hans' excellent troubleshooting guide I updated the firmware and suspected at least one blown BS170. Indeed it turned out to have been a bad day for Q11:
?
I replaced all four BS170s and, while the board was in front of me, I took the opportunity to resolder some of the inductor windings where it looked like dry-ish joints due to poorly burned off enamel might cause a problem.
The TX side seems OK: on the three bands I have enabled the transmitter is delivering around 2.5W on each of 40m and 30m and 4.2W on 20m. However I seem to have upset the RX side as this is what I get from RF sweeps on all bands:
Given that the TX side is doing OK, is it safe to assume that the LPF inductors are probably OK and I need to look for anomalies on the board around L12 and the trifilar transformer?

Re: Feeding 30 MHz into the Si5351A with the Ultimate3S
Hello Halden
30MHz was tried before. The Si5351A works but the spectral purity is greatly impaired.
U3S would work too if you set the reference to 30MHz.?
But as I said if you put a spectrum analyzer on it and compare, you won't like it perhaps.

Re: Si5351a issues with frequency resolution (step size) at 144MHz (or even lower frequencies)
Hi Ron.? I don't think those frequency error examples are the best I can do if I switch to the Adafruit library, which seems to allow easier direct? manual control of some of the parameters Using the Adafruit library and using the clockgen.setupPLL function, you can setup something like this clockgen.setupPLL(SI5351_PLL_A, 34, 463868, 762939);
This sets PLL_A to the reference frequency (25MHz) * (34 +?463868/762939), which is what ClockBulder Desktop suggests. ClockBulder pro suggests? 34.6080016 but gives no integer divider in the report. Presumably it incorporates integer dividers in the suggests C++code for the SI5351 registers. It presumably used the same fraction as ClockBuilder Desktop.
PLL A
?Input Frequency (MHz) = 25.000000000
?VCO Frequency (MHz) =? 865.200040002
?Feedback Divider = 34? 463868/762939
?SSC disabled
?
Output Clocks
Channel 0
?Output Frequency (MHz) = 144.200006667
?Multisynth Output Frequency (MHz) = 144.200006667
?Multisynth Divider = 6
This works with the Adafruit library, but the problem is that it doesn't quite give the desired output frequency (144.200006667). The problem is that the Frequency Divider should actually be 34.6080016, and that's not quite the same as the fraction given by Clockbuilder desktop.
463868/762939 = 0.608002736784985431338...
so the xtal is multiplied to (25*34.60800142606420) = 865.20003565160517...
when this is divided by 6 gives 144.200005942, an error of 0.725Hz
I think 463868/762939 is the best you can do with 20-bit registers (I think they are 20bit?), so using this method you may get close to the desired frequency, but still nowhere near the 0.001 or even 0.01Hz accuracy that you see quoted for the Si5351 in various places.
The other issue is coming up with a good algorithm for calculating the nearest set of 20-bit numbers to use for the fractional divider. How do you turn? 0.6080016 into a fraction (nearest the correct value) using only 20-bit numbers? That's what ClockBuilder does, but if you have to run ClockBuilder for every frequency you want to generate (and codes like JT65 and Q65 have 65 frequencies) it gets a bit tedious, even for just one sync (base) frequency.? And you are still not exactly on frequency for? of the tones.?
The final divider in the chain from PLL_A to the output frequency is an integer (Multisynth Divider = 6).? I guess in order to get higher frequency resolution, you would have to use a fractional divider, and from what I can see, this has to be somewhere between 8 and 900. I don't then see any way to use a fractional divider to generate a signal near 144MHz.? If the PLL limit is 900MHz and the Multisynth Divider can be integers 4, 6 or 8, or fractions between 8 and 900, you can never use fractions above 900/8 = 112.5MHz and so probably never generate signals above 144MHz to better then the nearest 1Hz.? You might be able to generate a particular frequency with the right crystal and fractional divider, but you can't then step the frequency in uniform sub-Hz steps. This would make WSPR on 144 a difficult task, though maybe you can get close enough to the 1.465Hz tone spacing to get it to work (sometimes?). I think I've seen posts saying that it is possible, though I've also seen comments in code that it doesn't).
Am I understanding this correctly? If so then the only way to generate 144Mhz signals with high accuracy and resolution, would probably by using harmonics, probably working at 48MHz and looking at the 3rd harmonic. Accuracy abd step size would be 1.3 of that at 48MHz, but probably still better than directly synthesizing at 144MHz.
Or am I still missing something?
