To acknowledge that a transmission has been received and
understood in its entirety, simply use the expression “R R R” spoken
as “Romeo Romeo Romeo” (“R” stands for received). Note: some
radio operators use the expression “Roger” instead of “Romeo”.
4. Antenna height and range of communications are intimately
related. In general, a higher antenna will have a longer range than a
similar lower antenna.
The typical range for a transmitting radio held at about 1.2 meters
(4.0 ft) above average water level is expected to equal 4.5 kilometers
(2.8 statute miles). The receiving shipborne antenna can extend the
range if it is mounted high. Airborne receivers greatly extend the
above range (over 150 kilometers/100 miles for aircraft flying over
1500 meters/5000 ft).
Because of the above fact, and to maximize the range of the survival
craft VHF radiotelephone, the unit should be held as high as possible
without endangering the safety of the operator.

tested on a periodic basis (FCC regulations, Part 80, section 80.834,
until superseded by section 80.1095).
