The Homebrew Transmitter and Receiver
We thought that something to use on this mode would be appropriate
The Paraset is a small British
The range covered from the receiver is 3.2 - 8 MHz on AM and CW modes.The transmitter is cristall controlled and works on the same receiver range
The Rechargeable Battery Cycler
The Battery Cycler is an autonomous device that will periodically discharge and recharge Nickel Cadmium Ni-Cd or Nickel-Metal-Hydride Ni-MH battery packs so that they are always fresh and ready to deliver
TNC Terminal Node Controller
TNC semplice e poco ingombrante da collegare al mio vecchio FT 2700 per ricevere i cluster di segnalazione DX
UHF 70cm Band Low Noise Antenna
A Low Noise Antenna pre-amplifier (LNA) is a simple unit which offers spectacular improvement in the quality of receiving signal, especially when the signal is very weak and it comes from long distance

23cm Yagi Antenna building Finished antenna at 1275 MHz SWR under 1:1.5 at resonant frequency
50 MHz preamp Gain 26dB with the BFG135 Preamps for 144 and 430 MHz, for 50 MHz, the BFG135a is a cheap transistor and in my view rather strong. It is not easily damaged by static discharge or RF power. FG connection
30 Volt Computer Power Supply Stack A bonus was that i discovered that these did not need a standby load connected to the supply to keep them running just apply mains power and close the Start lead to ground
