Interfaccia optoisolata PTT per modi digitali
Un interfaccia di solo 1.5 centimetri X 1.5 centimetri, un quadratino che contiente 5 componenti, esso permette di commutare in trasmissione apparati radio per poter operare nei modi digitali
RS232 CAT interface and PA buffer for Elecraft K2
a simple interface for Elecraft K2 with KIO2 and a buffer to switch on TX an external Power Amplifier
RS232 CAT interface for Yaesu FT-1000MP
Yaesu FT1000MP Mark V. This radio has a standard RS232C CAT interface and it is ready to be connected with a PC
Yaesu FT1000 & D rs232 homemade interface
The only way to get connected the ol'FT1000 rig to a modern CAT program is to have an rs232c level converter and the latest ROM Eprom version
Fsk Keying Interface
With a suitable interface, this signal can connect to the FSK input of an HF transceiver to produce spectrally pure FSK RTTY signals

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
Atu balanced feeder antenna system An ATU has the advantage of bringing the feeder-antenna system to resonance, act as a band pass filter both on receive and transmit and a low SWR
