Electromagnetic compatibility and Radio spectrum Matters ERM Digital Mobile Radio DMR Systems Part 4 DMR trunking protocol. The output circuit can handle a mismatch of up to 2 1, and an SWR of up to 1. The operation of the ACOM 1. S is very simple, you just need a coaxial cable and a PTT keying line. This allows practically any ztransceiver to be used as a driver. The CAT interface of the PA can be used to inform the amp of the currently set frequency. But even without a CAT cable it works fully automatically, the 1. S measures the input frequency and adjusts everythnig by itself. Serial Number Hand 9 Torrent. A large colour LC display show all relevant operating parameters. A service memory stores up to 5. This allows very fast and efficient analysis of errors and technical problems. To offer a safe operation even when the power grid is not perfect for example at fielddays or expeditions the ACOM 1. S uses a very elaborate switching power supply, which can also handle large variations of the input voltage. Further the inrush current is limited at start of the amp, a power factor compensation PFC is applied as required in many countries and much more. Due to the relatively low weight of just 1. PA is also suitable for expeditions. The power input is an AC input ranging from 9. V AC, the maximum power intake is 2. VA when operating or 1 VA when stand by. Technical Data Acom 1.

S is the first and long awaited transistor amplifier by Acom. The amp is characterised by a very high robustness, very easy operation and relatively leight weight. This makes this PA especially useful for DX peditions and portable operations. The output power is max. W on all bands 1. The heart of the ACOM 6. S are 4. 8V type MOSFET transistors made by Freescale, a type which is made to withstand even some SWR mismatch without problems. Operation with the ACOM 6. S is very simple. Required are just a PTT keying line negative ground and HF from the transceiver. An input power of 2. W is sufficient for full output power. The wideband input circuit is designed to offer a flat SWR of 1. Band switching is done automatically, the amplifier senses the input frequency. Numerous security checks prevent operation in case of an error. The last 2. 8 incidents are logged with many data points for later diagnosis. The large colour LC display shows all important data at a glance output power, reflected power, temperature, band and much more. Settings are controlled with a clearly arranged menu system and six push buttons below the display. A CATAUX interface can be used optionally for communication with the transceiver. All usual transceiver CAT systems and protocol types are supported. Additionally a seria l. RS 2. 2 interface can be used for remote control. The power supply shows the focus Acom has put on international use of the amplifier ACOM 6. S. The power supply is suitable for all AC voltages from 8. V. The inrush current is limited automatically, a very good power factor correction PFC is used to fullfill inuterbational industry standards. Together with the automatic adaption to varying input voltages this makes the amplifier very well suited for use with power generators, changing input voltages etc. The ACOM 6. 00. S does not provide an automatic tuner. What Is A Hiab License. Up to an SWR of 2 1 the amp will work without trouble, up to an SWR of 3 1 only with reduced power and above 3 1 it will switch off with an error message. Technical Data Acom 6. S Amplifier.

ACOM 2. 00. 0A 1. W, 1. 60 1. 0mThe ACOM 2. A Automatic HF Linear Amplifier is the worlds most advanced HF amplifier designed for amateur use. The ACOM 2. 00. 0A is the first amateur HF amplifier to include both fully automatic tuning and sophisticated digital control capabilities. This revolutionary new amplifier delivers maximum legal power in all modes and operates on all HF amateur bands. The ACOM 2. 00. 0A represents a major advance in the state of the art in HF amplifier design. It changes forever the way radio amateurs employ HF power amplifiers in their stations. Instantaneous, automatic tuning makes slow, cumbersome band changes a thing of the past. A built in, wide range antenna tuner matches loads with high VSWR up to 3 1, often eliminating the cost and complexity of an external, high power antenna tuner. RS 2. 32 digital control permits full integration into any computer driven station configuration. Advanced protection circuits ensure amplifier safety under every potential combination of operating conditions. Remote diagnostic features and modular design ease fault isolation and repair. At the core of the ACOM 2. A is a classic HF amplifier design, employing two Svetlana 4. CX8. 00. A GU7. 4B high performance ceramic metal tetrodes operating in a grid driven configuration. This design was chosen for its inherent stability and extremely low production of spurious emissions. ACOM coupled this tried and true configuration with todays most advanced digital control technology to create an amplifier with outstanding performance, features and reliability. Grid driven tetrodes, cathode negative feedback, excellent transceiver loading typically below 1. VSWR, and regulated SG voltage result in an extremely low distorted output. Measured typical IMD are 4. B 3 rd order and 4.
