Многие производители любительской аппаратуры имеют в своём ассортименте несколько простых недорогих моделей трансиверов, ориентированных в первую очередь на радиолюбителей, делающих первые шаги в мир любительской радиосвязи. У ICOM такой моделью в линейке КВ трансиверов является IC-718.
При своих размерах 240мм Х 95 мм Х 239 мм IC-718 представляет собой достаточно компактный настольный трансивер, своим дизайном отдалённо смахивающий на военную связную аппаратуру. Большую часть передней панели трансивера занимают жидкокристаллический дисплей c подсветкой янтарного цвета, ручка настройки и громкоговоритель. Концентрические регуляторы AF (RF/SQL) и RIT (IF SHIFT) расположены прямо под дисплеем в центре лицевой панели трансивера. Наиболее часто используемые элементы управления MODE, FILTER и TS выполнены в виде кнопок, которые немного выступают над поверхностью лицевой панели, и расположены непосредственно над ручкой VFO. Большинство отавшихся кнопок, включая клавиатуру для прямого ввода частоты, занимают правую часть лицевой панели. Сюда же выведены 8-ми контактный разъём для подключения микрофона и 6.3 мм гнездо для наушников.
Задняя панель выглядит простенько. Помимо гнезда SO-239 для подключения антенны, стандартного 6-ти контактного разъёма для подключения блока питания трансивера, присутствуют разъёмы для управления внешним автоматическим антенным тюнером и подключения аксессуаров, а так же порты для управления трансивером при помощи компьютера и подключения внешнего усилителя мощности.
Максимальная выходная мощность IC-718 составляет 100 Вт в режимах SSB, CW, RTTY и 40 Вт в режиме AM. Выходная мощность трансивера плавно регулируется в диапазоне 5-100 Вт (2-40 Вт в режиме AM).
В меру интуитивно понятный
Если вы уже владели трансиверами ICOM, то разобраться с IC-718 даже без изучения руководства пользователя не составит особого труда. Подключение антенны и необходимых аксессуаров, а так же первичная настройка трансивера после первого включения не вызовет никаких затруднений. Там всё просто и доступно даже для не самых опытных пользователей. Для более детального изучения функциональных возможностей трансивера, вам всё-таки придётся потратить некоторое время и обратиться к руководству пользователя. В IC-718 доступно два типа меню — для быстрой и начальной установки параметров. В меню быстрой настройки доступно 13 опций — установка выходной мощности трансивера, трёхуровневая регулировка яркости дисплея, регулировка микрофонного усилителя, настройки VOX, а так же основные параметры режимов CW и RTTY.
В меню начальных установок доступны следующие опции: параметры индикатора уровня сигнала и выходной мощности, звуковая индикация нажатия клавиш, уровень громкости тона CW, скорость сканирования приёмника и условия возобновления сканирования, переназначение функций ручки регулировки RF/SQL, тип телеграфного манипулятора, а так же ряд настроек, связанных с внешними аксессуарами.
Все опции меню имеют 8-ми символьное буквенно-цифровое мнемоническое обозначение, так что вам не составит особого труда найти нужный пункт для изменения настроек трансивера.
Итак, IC-718 достаточно прост в работе и позволяет выйти в эфир даже без детального изучения документации.
Если же вы предпочитаете начинать знакомство с новым трансивером с чтения руководство пользователя, то тут вы тоже не будете разочарованы. Руководство очень хорошо организовано и структурировано, вся информация изложена последовательно, поэтому с его помощью очень просто изучать функционал трансивера. Кроме того, руководство содержит разворот с блок-схемами и принципиальными схемами трансивера.
Повседневная эксплуатация
Переключение диапазонов в IC-718 выполняются при помощи клавиш UP/DN. Однако, если вам больше нравится крутить ручку настройки, то тут поможет клавиша TS, предназначенная для выбора шага перестройки VFO. Таким образом вы можете довольно быстро перестраивать трансивер в широком диапазоне частот. Более того, если вращать ручку настройки быстро, то трансивер автоматически будет увеличивать шаг перестройки VFO.
Безусловно, трансивер позволяет сохранять до 101 выбранных частот в памяти, а затем, переключившись в канальный режим (клавиша CH), перебирать их последовательно клавишами UP/DN или перейти к нужной ячейке, набрав её номер на клавиатуре.
IC-718 поддерживает 2 VFO, что позволяет ему работать с разносом частот приёма и передачи. Эти параметры так же могут быть сохранены в памяти трансивера.
В IC-718 реализованы два режима сканирования. Один из них предназначен для сканирования частот, сохранённых в памяти трансивера. К сожалению, в этом режиме нет возможности исключить отдельные ячейки из процесса. Другой, программный поиск, предназначен для поиска сигналов в заданном интервале частот. Реальность такова, что многообразие сигналов, уровни которых могут значительно отличаться, а так же всевозможные случайные помехи, делают этот режим практически бесполезным, что в не меньшей степени справедливо и по отношению к другим, более дорогим трансиверам.
Цифровая радиосвязь
Работать цифровыми видами радиосвязи, такими как RTTY или PSK31, на IC-718 очень просто. Вход и выход аудио, а так же сигнальные линии для управления режимом приём-передача собраны в 13-ти контактном разъёме для подключения аксессуаров. Трансивер не перегревается при длительных включениях на передачу даже на максимальной мощности. Принудительный теплообмен обеспечивается внутренним вентилятором. Вентиляционные отвертия находятся на дне корпуса трансивера. Сам вентилятор шумит вполне умеренно.
IC-718 обладает превосходной температурной стабильностью частоты. Несмотря на это, в трансивер можно установить опциональный высокостабильный генератор. Для любителей FSK в разъёме для подлкючения аксессуаров есть соответствующая управляющая линия.
С PSK31 у IC-718 так же не возникает никаких трудностей. Даже при использовании самой обычной звуковой платы компьютера на выходе получается кристально чистый сигнал без каких-либо внеполосных излучений.
Единственная проблема первых выпусков IC-718 — это очень большое время переключения приём-передача, порядка 290 мс. Если для аналоговых видов модуляции, равно как и для отдельных цифровых видов связи это не принципиально, то для режимов, при которых происходит быстрый обмен короткими посылками (PACTOR, G-TOR, AMTOR, Clover), этот показатель является катастрофически недопустимым. Для таких видов связи крайне важно, чтобы трансивер после передачи блока информации практически моментально (не более 35 мс) переключался на приём и был готов принять данные. В противном случае он попросту будет терять начало каждого информационного сообщения и установить связь будет просто невозможно. Чтобы исправить эту проблему в ICOM отреагировали разработкой модификации трансивера. Если вам достался один из медленных экземпляров, то придётся поискать решение, которое снизит время переключения приём-передача до 25 мс.
Радиосвязь телеграфом
Телеграфистам IC-718 предоставляет стандартные функциональные возможности. Трансивер оснащён электронным ключом, скорость передачи которого регулируется в пределах от 6 до 60 слов в минуту. Длительность посылок и пауз так же можно отрегулировать на свой вкус. Частоту тона самоконтроля можно изменять в пределах от 300 до 900 Гц. Громкость этого сигнала так же регулируется в широких пределах. В трансивере предусмотрен режим инвертирования боковой полосы в телеграфном режиме для улучшения приёма сигналов корреспондентов в условиях помех от соседних станций.
Телеграфный манипулятор можно подключить к разъёму на задней панели трансивера или прямо в микрофонный разъём на лицевой панели. Как это сделать хорошо описано в руководстве пользователя. Так же в меню есть опция, позволяющая превратить клавиши UP/DN микрофона в телеграфный манипулятор. Несмотря на то, что использование микрофона в качестве телеграфного ключа для передачи читабельного кода задача не из простых для нетренированных рук, тем не менее эта функция может оказаться полезной в условиях, когда нормальный телеграфный манипулятор недоступен.
Режим полного дуплекса в IC-718 реализован, хоть и сопровождается довольно громкими щелчками реле коммутации приём-передача. В общем этот трансивер больше ориентирован на тех, кто проводит телеграфные связи не очень часто.
Полезные дополнения
IC-718 допускает установку одного дополнительного фильтра промежуточной частоты. Если вы работаете в эфире преимущественно телеграфом или радиотелетайпом, то 500 Гц фильтр будет неплохим дополнением для данного трансивера. Вся линейка доступных для данного трансивера фильтров включает фильтры 250 и 500 Гц для CW/RTTY, а так же 1.8, 2.8 и 3.3 кГц для SSB. Для амплитудной модуляции фильтров нет. Фильтры устанавливаются на плату трансивера при помощи пайки. Несмотря на то, что сам по себе процесс установки опционального фильтра ни у кого не должнен вызывать никаких сложностей, многие радиолюбители всё же предпочитают более гибкие решения, когда фильтр устанавливается в предусмотренный разъём без пайки, что в первую очередь позволяет быстро менять один фильтр на другой в зависимости от текущих нужд просто сняв крышку корпуса трансивера.
Трансивер оснащён подавителем импульсных помех, параметры которого можно плавно регулировать. Для этого достаточно несколько секунд подержать нажатой кнопку NB и при помощи ручки VFO установить требуемы уровень шумоподавления. В IC-718 этот фильтр весьма эффективно позволяет бороться с помехами от систем зажигания автомобилей.
В отличие от некоторых моделей трансиверов эконом-класс других производелей, в IC-718 нет встроенного антенного тюнера. Можно подключать только внешние.
IC-718 оснащён встроенным измерителем КСВ, что является хорошим дополнением в трансивере, который по своим размерам вполне годится для использования в качестве мобильного или походного аппарата.
Любителей работать телефоном трансивер порадует наличием системы VOX. Дополнительно в него можно установить модуль синтезатора речи UT-102, который предназначен для информирования о значении рабочей частоты и показаниях S-метра.
Ложечка дёгтя
Один из недостатков IC-718 — это отсутствие режима FM. Всё-таки FM достаточно широко распространён на 10-ти метровом диапазоне. При хорошем прохождении там всегда можно услышать станции, работающие в FM. Трансивер перекрывает FM-участок диапазона 10 м, поэтому наличие возможности слушать и проводить связи в режиме FM добавило бы этому трансиверу привлекательности среди потенциальных покупателей, хотя, возможно, и увеличило бы его конечную стоимость. В конце концов ICOM следовало бы рассмотреть такую возможность хотя бы с помощью опционального модуля.
Ещё одна проблема этого трансивера — фиксированная АРУ. В IC-718 полностью отсутсвует возможность регулировки времени срабатывания АРУ. Безусловно, никто и не ожидал увидеть в подобном трансивере плавную регулировку АРУ, но хотя бы на уровне быстро/медленно она должна быть, как весьма полезная функция, способная сделать приём определённых сигналов в определённых условиях более комфортным.
Заключение
Для присутсвия в эфире от случая к случаю вам вовсе не нужно тратить огромные деньги на аппаратуру. Дорогая аппаратура с множеством сервисных функций ориентирована в основном на заядлых радиоспортсменов и охотников за DX и большинству радиолюбителям многие из них могут вообще никогда не потребоваться. Если вы не из числа «профи», то всё что вам нужно — это простой недорогой трансивер, который позволяет выйти в эфир и наслаждаться любимым хобби. Этим требованиям IC-718 соответствует в полной мере.

n Unpacking
After unpacking, immediately report any damage to the
delivering carrier or dealer. Keep the shipping cartons.
For a des cri pti on and a di agra m of acce sso ry
equipment included with the IC-718, see ‘Supplied
accessories’ on p. 1 of this manual.
n Selecting a location
Se le ct a location for the transceiver that allows
adequate air circulation, free from extreme heat, cold,
or vibrations, and away from TV sets, TV antenna
elements, radios and other electro-magnetic sources.
The base of the transceiver has an adjustable stand
for desktop use. Set the stand to one of two angles
depending on your operating conditions.
n Antenna connection
For radio communications, the antenna is of critical
importance, along with output power and sensitivity.
Select antenna(s), such as a well-matche d 50 Ω
antenna, and feedline. 1. 5:1 or better of V olt age
Standing Wave Ratio (VSWR) is recommended for your
desired band. Of course, the transmission line should be
a coaxial cable.

n Grounding
To prevent electrical shock, television interference
(TV I), b road cast inte rfe renc e (BC I) and othe r
pro blem s, gr ound the t rans ceiv er th roug h the
GROUND terminal on the rear panel.
For best results, connect a heavy gauge wire or strap
to a long earth-sunk copper rod. Make the distance
between the [GND] terminal and ground as short as
possible.
R WARNING: NEVER connect th e
[GND] terminal to a gas or electric pipe, since the
connection could cause an explosion or electric
shock.
30 mm ≈ 9⁄8 in 10 mm ≈ 3⁄8 in 1–2 mm ≈ 1⁄16 in
Antenna SWR
Each antenna is tuned for a specified frequency
range and SWR may be increased out-of-range.
When the SWR is higher than approx. 2.0:1, the
transceiver’s po wer dro ps t o pr ote ct t he f ina l
transistor. In this case, an antenna tuner is useful
to match the transceiver and antenna. Low SWR
allows full power for transmitting even when using
the antenna tuner. The IC-718 has an SWR meter to
monitor the antenna SWR continuously

FREQUENCY SETTING
n VFO description
VFO is an ab bre via tio n of Var iab le F req uen cy
Oscillator, and traditionally refers to an oscillator.
The IC-7 18 VFO ca n stor e a fre quenc y and a n
operating mode.
You can call up a desired frequency to the VFO with
the keypad or the memory transfer function (see p. 37).
You can also change the frequency with the tuning dial
and select the operating mode with the [MODE] switch
or call up previously accessed frequency and modes
with the band stacking register (p. 18).
The IC-718 has two VFOs, specially suited for split
frequency opration. The VFOs are called VFO A and
VFO B. You can call up the desired VFO.
• Differences between VFO mode and memory mode
VFO MODE
Each VFO shows a frequency and operating mode.
If the frequency or operating mode is changed, the
VFO automatically memorizes the new frequency or
new operating mode.
Whe n th e VF O is selected fr om a not her VFO
or me mory mode, the last-used fr equency and
operating mode for that VFO appears.
[EXAMPLE]
MEMORY MODE (pgs. 35–38)
Ea ch memory chann el shows a frequen cy and
operating mode like a VFO. Even if the frequency
or mode is changed, the memory channel does not
memorize the new frequency or operating mode.
When the memory channel is selected from another
memory channel or VFO mode, the m emorized
frequency and operating mode appear.
