CMOS Pseudo Doppler Direction Finding System |
| Voice Programmer and Automated Fox Transmitter The X-mtr is low power but can be heard for a thousand feet. Its a good thing that it is low power, as it puts out as much AM as FM..... It is quite small, easily fitting in a cigarette pack! Jan. 6, 2004: ERROR CORRECTED On the FOX TRANSMITTER: Pin 7 of the ISD1420 is floating, while pins 5 and 6 are tied together and tied to 0V. Previously, 5,6 and 7 were shown incorrectly as tied together and tied to 0V. |
