This
is the most obvious thing to get started. At least we need Radio, Antenna
and Cable.
There
are alternatives on having this equipment: Make or Buy.
Radio
is a two way, from Handy Transceiver (HT), Mobile Radio, or Base Station.
To
make it work, we have to have a match configuration of
Radio-Cable-Antenna, depending on where (in MHz) and what (in Mode) do you
want to operate.
For
example, if we want to work Voice DX in 15m band, we need a Radio capable
on transmitting (and receiving) in 15m (21MHz) and Antenna designed to
work on 15 m band, coupled with Cable suitable for coupling the Radio to
the Antenna.
There
are two basic aspect on 2 way Radio: Transmitter and Receiver.
On
transmit, how much power it can produce (in Watts ranging from 1 watt to
200watts), on Receive how good it can hear the weak station (sensitivity).
Of
course this is also depending on how good the antenna is.
In
case you Radio does not have enough power, an Amplifier can be added to
boost the required output power.
In
case the antenna and cable is slightly mismatch, an Antenna tuner can be
added to 'adjust' the coupling between Radio-Cable-Antenna to a safe
level.
