Simple qrp transverter for 70mhz
the transverter is 70mhz to 28mhz as on 10m i have various rigs that i can use. also, it only requires a simple 3rd overtone crystal oscillator at 42mhz

13 CM transverter
Here it is shown connected to a 120w amplifier, which is sitting on top of it.This transverter can deliver about 25w on it's own, and runs on 12v, making it suitable for portable service. When at home with 28v available, I use it with the 120w amp.It's a hybrid, and consists of a basic DEMI transverter board kit, a driver board out of a Spectrian amplifier, and my own T/R control board
1296 MHz Transverter kit
Build the kuhne mku 13g2b kit. the kuhne transverter covers 1296-1298 mhz and the if is at 144-146 mhz

il circuito e' funzionato al primo colpo le tarature non sono critiche

Take off angle of horizontal antenna For horizontal polarization, the electric field will move sideways on a horizontal plane, while for vertical polarization it will oscillate up and down on a vertical plane
Rx antennas 4Square Rx Vertical Array My frequency design of 1.825 MHz a 90 degrees line would be 33,70 metersinstead of the previously calculated 33,27 m
Calculo da Antena Bazooka A double bazooka antenna is a combination that has a complete coaxial wave multiplied by its velocity factor and a total end-to-end length of 1/4 wave for each side affected by another driver shortening facto
