2m - PA7MU

144MHz FM/SSB Receiver by DL5NEG
After I had developed a couple of shortwave and VHF-FM Receivers in my sparetime, I decided to develop an allmode receiver for the 144 MHz amateur radio band as my university graduation thesis.

2m.Ontvanger FM 144 Mhz de F6FEO
Voici un récepteur FM VHF très simple réalisé à l'aide de composants récupérés sur une épave de téléphone sans fil.
Il faudra y dessouder : deux circuits intégrés, le filtre à quartz 10F7.5A, un quartz 10.245 Mhz, le filtre céramique et un pot FI 455 Khz.

Un transceiver 144 SSB
Le PICARDY par
F6FEO Principe de fonctionnement
La platine de base du transceiver SANTERRE est utilisée en moyenne fréquence fixe sur 22.915 Mhz.
Un transverter équipé d'un VXO ultra-stable sur 121 Mhz permet un trafic confortable dans la bande SSB 144 Mhz.

UN AMPLI 144 AVEC UNE GS31B
par F6CHT Shematic

This 7-Element-28-Ohm-DK7ZB-Yagi
has the highest gain and best F/R for
CW/SSB/EME-use between 144 and
144,6MHz.

For two purposes a Cross-Yagi can be useful: Satellite work or if you need both vertical and horizontal polarization for terrestrial contacts.You can use two different feeding methods: Always cross polarization or switchable for vertical, horizontal an right hand cross polarization.
