Larry,
I can understand the airline battery conflicts definitely as I fly with Radios from time to time. If it were just the battery that were missing maybe but that is not all that doesn't work and the QC is terrible, not kidding the solder flux had not been cleaned off what had been soldered.
At a hardware level it looks like a STM32 and a TLV320 are present, so connect a USB and you should at least see the USB idVendor and idProduct codes on the USB bus? As the docs all seem to suggest there is a boot loader present. I'll confirm later.
AFAIK an STlink V2, or similar, should tell you what had been loaded on the STM32 MCU. Assuming he ICSP headers existed. As the screen says 50Kz to 900MHz I assume the appropriate firmware was loaded. Not sure an SA602 can handle 900MHz anyway.Bit loath right now to tinker until I can work out is the unit going to work at all.

Dom,
There are VERY strict guidelines as to what types of equipment can include Lithium batteries if being shipped by air.
Many Asian vendors have been burned by having their shipments returned due to being refused air shipment due to the inclusion of Li batteries.
So, they have started to ship their products without them.
I for one am happy to get my items faster, even if they don't include the batteries.
I can buy the Li batteries locally and it ensures I'm getting new cells, not old stock that may fail in 6 months.
Regards,
Larry
