Now here's another device. It follows the same basic outward form as so many others, but at first glance, the main buttons are angular. In fact, the battery compartment has angular champferings. Opening it up, the PCB is an angular shape too!
The display is the chunky one a la Belkin. No flashlight or clock on this model. Coverage starts at 88.1MHz, thus sadly missing off that rather useful 87.5-88MHz range. Highes attainable frequency is 107.9MHz. Memory is non-volatile thanks to a 24LC402 EEPROM. There are four different memories rather than the usual three. The switches are a nice quality component as opposed to an open membrane type affair.
There are three chips, one being the EEPROM, one is the 'blob' under the display, and the third looks like it takes care of all the PLL and encoding tasks. This is an 18 legged beastie and is sadly unmarked
The PCB reads

Power supply is by coaxial DC socket on the side of the unit. Power goes straight in to this unit at 12v and so this device is not able to be powerered from USB. It takes 2 AAA batteries in the normal fashion. 3v is found at the battery terminals when the unit is externally powered. I found that my unit got quite hot after just a few minutes of being powered up. The heat source appeared to be the batteries.
The unit shuts down after 55 seconds if no audio is detected. It does not re-activate if an audio signal is re-introduced.
