Interface transceivers with a built-in RS-232C
For transceivers with a built-in RS-232C interface a serial cable is enough for the computer connection
FT-817 CAT Interface
Here is the schematic of the simple CAT interface I use with my FT-817
Interface for FT857
this intefrace works for 706 and ft857 along with other 6 pin data connections
ICOM C-IV Interface
The following ICOM CI-V circuit has been constructed to connect the ICOM radios to a computer via the RS232 port
Dual Radio Computer Interface
the simple interface I use between my Hitachi laptop and my FT-1000 Mk5 Field and FT-817 transceivers

Linear loaded short dipole 21Mhz For my amateur radio activities on the HF bands I only have a 3.6 m wide balcony available for antennas. After some study I decided to experiment with a shortened dipole for the 15 m band
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
