I like the TPA2016. I've been using
a 15W/ch class D amp to drive my main station speakers for 2 or 3
years and haven't noticed any RF noise.
One aspect of the uBitx AGC
consideration I haven't heard much on is.... to what extent, if
any, do strong signals outside of the recovered audio pass band,
but inside the 45 or 12 mhz passbands affect the mixers and amps
in the RX chain? Is there an optimum max signal level?

Well since Atmel is now Microchip
I have the PICKit 4 Programmer/Debugger and now that Atmel is
under Microchip the new PICKit 4 box will program PIC, AVR and ARM
chips. Although I also have an Atmel ICE to fall back on when the
PICKit does not handle a particular AVR chip. They are gradually
merging their toolsets to handle PIC/AVR/ARM chips more
seamlessly. So Microchip may cover all the bases.
The Nordic chips are interesting. When it comes to battery
operation, some folks seem to prefer these. I bough a LoRa
development module based on one of these chips. I use manufacture
toolsets often, but the documentation from the LoRa development
board is helter skelter.
I'm learning more about these chips, as I ended up buying a
genuine Nordic development board, a J-Link Programmer/Debugger and
installed the Segger toolchain, so I have a known starting point
before tackling the Lora board (and disorganized documentation)
again. The Segger stuff is first class (fortunately it is supposed
to be free to use with Nordic chips), but even with experience on
multiple manufactures toolchains, culling through the many
disconnected documents and connecting the dots, is making this
toolchain one of the longest for me to get set up with.
If Nordic chips get more support in the Arduino IDE it would be a
real benefit to the casual user. I Like the ease of Arduino IDE
with the consistent libraries and the (at least most of the time)
just works programming environment. For the Arduino environment it
might be good if they try supporting the inexpensive ST-Link V2
clone programmers to program boot loaders into the Nordic chips.
