OK, the pass 2 boards have arrived, they look good so, let er' rip.

Ordering instructions are in the attachment and a copy is in the Files section under my call. Not sure how all this is going to work out due to the qtys ....let's see.?

Please remember I'm still only one retired guy sitting at one table.

2) Use the UART debugger permanently burned into processor ROM by ST at the factory.
? ??
It's always present, is ROM not flash in that it can't be erased.? Probably supported by ST processors only.
I prefer this method, as I find a UART easy and familiar and I already have the hardware:
? ??
A description of that cp2102? ?USB-to-UART adapter is in post 50027, there are plenty of other such devices.?
If things don't work, can first debug that USB-to-UART adapter by tying TXD to RXD for loopback mode,
and try talking to it from something like a VT100? terminal emulation program.? If anybody still knows what that is.

I have a feeling I am oversimplifying this.? It looks like Allison is getting closer to figuring out how to flatten the power output across all bands.? That is very exciting and a huge improvement.? However, it got me thinking.? Right now I am getting a little over 9w on 80m and about 8w on 40m.? Lately I have been spending time on 30m and 20m digital which both have an output under 5w keeping me in legit QRP range.? Let's assume Allison's project works and she shares it and I can figure it out.? To pick an arbitrary number let's also assume that my rig as an example post mod puts out a fairly even 9w across all bands.? That keeps us QRP for voice but not CW or data.? If I wanted to be able to switch back and forth is it feasible to connect two bias pots with a toggle switch and adjust one trimmer for 5w and one trimmer for 9w output?? For that matter what about 3 pots on a selector switch setting one more at 1w to drive an external amp?? As I ramble I wonder if you could also just bring the pot to the front panel and figure out a power meter but I like the idea of a set it and forget it switch.? Would this work or am I just exposing the gaps in my understanding?

If you are happy with ArduinoLand and prefer to stay,
this guy would be a very good choice in an ARM processor:

That's an Atmel processor, not ST.
Sold by the Arduino people, fully supported by the IDE.
Though I'm sure there are some Arduino libraries cooked up by others that haven't been ported.

Lol, I agree . Yesterday was the first time I had played with the blue pill in about 2 years. I had to relearn again. I find myself using STLINK ?v2 ?most of the time. I have used the other methods including using a Discovery F4 board to do it with which envolves ?using stlink program and hex ?file , works fine but a problem to set up. Yes and don't ?forget moving the jumper on boot 0 . All I have ever got to load and run on it are simple programs never been able to get anything as complex as the uBitx firmware. I seem to be missing some of the needed files for the stm that are already in their for the Arduino . ?I did see where one of the stm people was doing some rewrite ?on some of it especially the EEPROM ?which was something I always had errors ?in. This is why the blue pills I have have not been touched in 2 years. This thing does have some serious ?potential ?and a very good price. I know someone here on this site will get this thing up and going. ?Roger Clark has some very good information ?on it.

Rod:

It is Open Source. Google "mic compressor" and see if our speech compressor doesn't do what you're thinking about. When you say "it", what is the "it" you're referring to?

Hi Jack,

For my uBITX:

I have not been following the threads closely: is your software GPL open source?

I would like to just implement the rx filters.

I would also like to implement a mic high pass filter, followed by clipping, followed by a low pass
filter to remove the clipping residue. I have heard that gives some pretty good readability.

I am not so sure about mic compressing.

However, that introduces the issue of how to control it without an additional USB cable.

Thanks Jerry. I did not see a click to order button on HF Signals web page nor did I see an email address for special orders like this. Did I miss what is there or did their page change?
