The AmQRP “PIC-EL Kit” is a multi-function PIC16F84A-based project board designed by Craig Johnson, AA0ZZ and the American QRP Club for experiments being conducted by John McDonough, WB8RCR in his online PIC Elmer 160 course. The course material is geared around use of common I/O components — pushbuttons, LEDs, LCD display, rotary encoder and speaker…
I’ve tested new QRP FM Transmitter. The Power is 8.5 Watts with 13.8v DC. The idea – to use it as a FM TX for 2m band or for foxhunting sport events. Link to manufacture: FMUser.com
This double-sideband (DSB) radiotelephone transmitter is powered entirely by the instantaneous (not stored) energy produced in the operator’s voice. The RF output power in my prototype falls within the range of 5 to 15mW. The circuit is essentially a high-level DSB modulator/crystal-controlled RF oscillator.
