Can't bankrupt myself but I can see about being an intermediary source as well.

Thank you! I may take you up on that if it comes down to it. I already received a quotation from another vendor and placed an order. It doesn't solve the larger issue, but that should get things moving forward. I plan on ordering boards today if possible. I'll update again after everything is on the way for the next round.

Everything except the base/stand pcbs have been ordered. Thank you for all the input back and forth on the design, cost, and the trade-offs. It might not have seemed as constructive as it really was, but I do believe that this is exactly the direction that this should go for now. The boards and placement have already been approved for manufacturing. If nothing goes wrong with the parts orders, and if I didn't make mistakes on the changes, then we are all set! Because much of the pcb surface area is visible, I ordered with black solder mask for the adapter and analog boards. I think that will look nice in contrast with the Wio Terminal.
Another visualization with colors added.
Ordered the base/stand pieces today.

Looks good. I really like the header mount, very clean. I look forward to the finished product.
Did you have any luck with your parts order?

As far as I know right now, everything is on the way. I hope it works.

That is correct. I'm not going to be including the WIo Terminal display or the USB cable. It will include the receiver (analog + digital), the Wio Adapter, and the Base stand pieces. Assembled and tested. While supplies last, it will include a 700/800 MHz antenna and ear buds-with-volume-control. It isn't obvious from the visual, but there will be header / wire between the adapter and the analog board that will form an RF shield around the analog section. If I didn't screw anything up with the changes, then it should be a nice little receiver. For audio, I hooked up an Anker speaker with the line-out option and it sounds really good.
Here is an image of base/stand boards. Two of them per unit.

This is exactly what I was hoping for form factor-wise when I posted earlier in this thread. This will make it easier to find a way to enclose this and be aesthetically pleasing. I can't wait to get my hands on one and try it out!
Glad to hear it. I was hoping it would be more what you were looking for based on your description.
If base-stand idea doesn't work out well, I can do something else for that. I've never tried that before.
Not yet, but I will once the design is verified. It will be the same thing I was doing with the P25RX-II for the last several months. After you order, I will assemble, test, and ship within a few days (usually 3-4). At least, that is the plan for now.
I definitely will. I have the firmware for the new processor working very well. The main thing I need to finish before it could be sold is to finish the configuration part. There is going to be lots of flash memory and an SD card, so there are options. I don't really trust SD cards as "reliable" media in embedded applications, but it could be a great solution for cross-platform compatibility. What I'm thinking is mapping the SD card in as a USB mass-storage device, then writing configuration to the card with Java application. After that, the firmware will transfer the configuration information to the reliable on-board flash memory. I'll update later on progress for this. I was really hoping to get USB Ethernet emulation working on Windows and Mac, but I have not been able to get that to work. The CDC-EEM class works excellent on Linux and does open up some applications on that platform. I haven't checked to see if Android devices have the CDC-EEM driver compiled into the Linux kernel by default. For cross-platform compatibility, It will probably end up being USB serial like the other products, but it will be 40x the data rate with 512 byte FIFOs vs the 64 bytes. This will open up some possibilities for displaying a lot more real-time information. I saw another thread here on RR regarding visualization of activity using bitmap raster/images. It gave me a good idea for something similar. I'm looking forward to trying that out.
