Hi,

Looks a nicely finished unit but too much power to comply with the LPFM regs, so you'd need to trim it back in order to use it legally.  That's assuming it delivers what they say it does.

If Maurice is right about it being based on the Rohm 1415 chip, then as he says it's designed for use as an audio sender for ipods, etc.  The audio specs for the chip are adequate but nothing flash, though it does have a built in limiter and preemphasis (fixed at 50uS).  The output of the 1415 is quoted as 100dBuV (just enough to transmit across a room), so what happens when it is amplified up to 5 watts is a bit of an unknown.

It may well perform comparably with other budget transmitters and I guess you get what you pay for.

The antenna they supply with the unit is intriguing! 

Cheers,

Barrie
