The Ware for September 2022 is shown below.
I like the extra effort that went into the mounting of the elements on the right hand side of the lower photo. There’s a lot of cheaper ways this could have been done that involve some compromises, but this is probably one of the more robust yet repairable ways to do it that might also shave a couple mm off the final product’s thickness at the same time.
Thanks again to jackw01 for contributing these wonderfully photographed wares!
I think it is this Kirisun FM handheld transceiver:

Did you look at the internal pictures of that radio? They look nothing like this board.
Let’s see. There’s an antenna, what looks like some sort of squelch potentiometer, and side buttons for what could well be frequency change.
Given there are indications of a microphone, and a possible side mini-jack, I’d venture to say this looks like a Bodypack UHF Intercom, for use in live production.
It’s a handheld radio. The board says UHF and the signal path seems to be single band–I don’t see the filtration that I’d expect from a multi-band radio. It’s a tranceiver as it has an RX path and a TX path. The antenna connector appears to be a Belling-Lee which would suggest Europe or Australia. The processor is a 2007 release Reneasas chip. It’s 16 bit and had 128K of flash and 7.5K of SRAM which is a ton for a handheld radio from a decade ago! The construction suggests a quality designer/manufacturer, but it’s not a high end product, more likely mid-market. It has the standard knobs of a handheld radio–a pot and a rotary encoder. The pot has a lot more connections than I would expect as it doesn’t appear to be a co-axial multi-pot like some radios use for their squelch/volume stems. That implies it’s a commercial radio as an amateur one would have a separate squench control.
My guess would be a Yaesu-Standard made UHF CB for the Australian market. That fits the Japanese processor, the quality design, the antenna connector, the control setup, the headphone/mic jack config, and the lack of display. If it were an amateur radio, it would have to have a display and a squelch knob.
The only part that doesn’t fit is the much larger microcontroller than I would think you’d need for a radio like this. If it was an amateur radio with a display and a keypad with a complex UI, the uC would make sense, but for a display and keypad-less radio, it’s very odd to see such a big chip. And it’s not like this is a variable BOM board that’s common to a number of radios each with different options. There’s no sign of that type of design on the board. This device was built for one use only. Also, there’s no sign of a programming header, so that and the mid-tier build rules out commercial use in my mind.
I’m curious to see what it ends up being.
I don’t know much but X1 looks like a TCXO by KDS Daishinku, and the middle knob looks like a encoder whereas the knob towards the outside seems like an encoder. Not sure if this info would be useful at all.
Full credit to putting out a call on Libera and getting some sleuthing experience from xssfox (who’s attempt at a comment got blocked for spam): it’s a Kenwood TK-3300 series 2 W Part 90/95 UHF handheld transceiver. Matches with the Internal Photos for FCC ID ALH413603.

That sure does look like it! Reading the manual make it clear what the big uC was for. It has voice prompts and scrambling, so it’s doing a lot of DSP as well as audio sample storage, that explains the 16 bit micro and the 128K of flash.
The antenna connector matches between the pictures, but doesn’t match what’s shown in the manual. The manual shows an unshrouded SMA connector while the photos show some kind of shrouded connector.
Bunny, when this is over, can you include a better photo of the antenna connector? Please?
I think the unusual look of the SMA connector is mechanical to support the whip antenna.
What can I do to help you build the precursor? What free or paid work you need help with? I code 24/7 and I’m passionate about this mission of building private tech. I could make you some software, anything. I wanna talk about the possibilities. I can study hardware or software. I will learn and work on whatever needs help none stop. I have a work ethic and really wanna help.
