Frequency Meter with 100 MHz RF desktop channel - This basically the frequency
meter section of the frequency meter/pulse generator based on the AT90S2313 described
elsewhere on this site, combined with the 100 MHz RF interface described in the page about
the RS-232 to 100 MHz RF desktop channel adapter. Built and align this is the same manner
as the 100 MHz RF desktop channel adapter. The frequency meter....(electronic design added

Frequency Meter with Minimum Mass Wireless Coupler - A 0 to 2 MHz ferquency
meter with a Minimum Mass Wireless Coupler, based on the ATMega8.Range to the Minimum Mass
Base Unit is 10 to 15 cm. Since the frequency meter is battery operated, it can be floated
from ground, making life in and around the test bench a lot simpler. No need to connect it
to the computer or LCD display....(schematic added 6/07) |

Frequency meter with wireless Data Channel - This basically the frequency meter
section of the frequency meter/pulse generator based on the AT90S2313 described elsewhere
on this site, combined with the 100 MHz RF interface described in the page about the
RS-232 to 100 MHz RF desktop channel adapter. Built and align this is the same manner as

High Quality, All-Digital RF Frequency Modulation Generation with the ADSP-2181 & the
AD9850 DDS - AN-543-Analog Device Application Notes (app note added 6/06)

High Voltage, High Efficiency MOSFET RF Amplifiers - Application Note
Microsemi-formerly Advanced Power Technology APT0001 ( app note added 2/07)

High-Efficiency 400 Watt 13.56 MHz RF Power Amplifier - Application Note
Microsemi formerly Advanced Power APT9501(added 1/07) |

Improved 3 Transistor Audio Amp 80 milliwatt - This circuit is similar to the
one above but uses positive feedback to get a little more amplitude to the speaker. I
copied it from a small 5 transistor radio that uses a 25 ohm speaker. In the circuit
above, the load resistor for the driver transistor is tied directly to the + supply.
This has a disadvantage....(circuit diagram added 6/07) |

LCD Display with Minimum Mass Wireless Coupler - Its an adaption of the 2X 16
LCD project, by adding a fettite loop antenna, two resistors, and a capacitor. Here the
display shows the output of the 10 bit scanning voltmeter with Minimum Mass Wireless
Coupler. (ATtiny2313, AT90S2313)….(schematic added 6/07) |

Low Cost 1000 Watt 300 Volt RF Power Amplifier for 27.12MHz - Application Note
Microsemi-formerly Advanced Power Technology APT9701 ( app note added 2/07)
|
|
Low cost RF for simple data link & remote control - This section describes an
experimental low power, low bandwidth data signaling system that was initially made to
operate at 55 MHz (television channel 2 in the U.S.). Before operating a radio
transmitter, find out what kind of transmitter operation, if any, is permitted in
your....(added 6/07) |

Low Frequency Sine Wave Generator - The two circuits below illustrate generating
low frequency sine waves by shifting the phase of the signal through an RC network so that
oscillation occurs where the total phase shift is360 degrees. (added 2/03) |
