144MHz ARDF transmitter by ON7YD
The hart of the transmitter is the integrated circuit ICS501 that allows it to generate a stable a clean signal on 144MHz using just a few components.

144MHz CW Transmitter by OZ2CPU
Block Schematic of my homemade 144.000 MHz CW 1.5Watt transmitter. The Xtal osc is riped from an old AT-PC running 16MHz, it requeres 5.0 volt and use 18mA.

2m CW Transmitter by EI9GQ
I use this simple CW transmitter for working through the RS13 satellite. Using just 10 Watts and a dipole at 3M above ground, I have made many contacts around Europe and across the Atlantic.

FM Transmitter by SMØVPO
I have had requests to add a VHF FM transmitter, to the QRP collection. This project is a simple transmitter using only one crystal and will cover 145.00 to 146.00 MHz.

Un émetteur FM 144 Mhz expérimental de F6FEO
L'installation locale d'un relais VHF sur une fréquence incompatible avec le synthétiseur de mon ancien transceiver 144 Mhz au pas de 25 Khz, m'a amené à réaliser ce montage expérimental.
