Audio noise generator drives earphones or small speaker  -  This is a circuit that generates white noise, rolled-off to drive earphones or a small speaker. White noise creates is a "rushing" sound, which sounds something like air rushing by your ear(s). White noise would be flat with frequency, and since this circuit rolls off within the audio range, I refer to it as "rolled-off" noise. White (or rolled-off) noise(circuit added 6/07)
AVR ATMega8 board for PLL MC145170 -  This board allow to manage a FM transmitter including a Phase Locked Loop (PLL)on a serial bus (SPI) like a MC145170. A current frequency is memorized in EEPROM to configure PLL at power up. Three auxiliairy frequencies are available for maintenance function and/or HF adjust. A local interface include 4 keys and a LCD display enable to modify transmitter parameters.  This board can be completely drived from a serial link RS232 (19200 Bds,8b data,2b stop, no parity). A temperature sensor enable to control working temperature and 2 analog input are used for HF power measure (Forward and Reflected). Information about TOS protection activation is processed by this board to inform user (local and remote) on a TOS Alarm. .(electronic schematic added 11/08)
