Hey guys, somewhat new to digital programming…I have a general knowledge but nothing too in-depth.
Two questions: one is does the NS73M have a default frequency? I thought I saw 97.5 MHz somewhere but I don’t know where…
Also, if that’s true it would be perfect because my desired freq of transmission is 97.5 and I don’t want to have to include a microprocessor in the design. Will this chip work without microprocessor programming?

It must be initialized properly before it will start transmitting. By default, the power is turned off internally, until it is enabled. So no, it must be used with a microcontroller. There are other simpler FM transmitter chips, that use up and down buttons to control the frequency, but I can’t remember a part number just now.
Couldn’t you just use a USB to I2C adapter like this: http://www.cutedigi.com/cables/usb/usb- … aptor.html to do it?

You can take a look at something like this: [PIC MCU Controller Project for NS73M
Or something like this: [PC Project for NS73M
You could even create a complete PC-only controller for the NS73M by bit-banging the PC parallel port. Anyways, you now have two complete examples you can look at, or use as-is with little added work on your part.](Blog Index | Electronics Forum (Circuits, Projects and Microcontrollers))](Blog Index | Electronics Forum (Circuits, Projects and Microcontrollers))
