Maybe. I don't know how many rebadges there are out there, and agree with the x/y/z/... designation that there are a whole bunch of them. They all appear to have the same chips on the board but the other "stuff" on the boards are different. Like that picture on that website in post
#14 definitely has that same chip and the pots/lamps are the same locations, but all the passive components are different/different locations.
The suspected mod board has two ICs on it - a CMOS 4017 counter and a 4069 hex inverter, maybe it was intended to push the button sequence to get it into the Chicken Band every time it was powered up? No idea.
Wonder if this radio is worth to fix, the digital/logic/memory circuitry on it is dead and maybe more, no idea. I was hoping to at least find the service manual so I could use the analog portion, would be nice to have a working SSB modulator/demodulator I could control with my own digital circuitry to replace the dead portions, at least. But there's a chance the analog stuff is also damaged...
Based on the fact there are so many rebadges, seems like this is a fairly popular radio or mass produced enough that it's not worth to repair...?
