AR8200 MKII Scanning Receiver
(Discontinued)A Temperature Compensated Crystal Oscillator (TCXO) now forms the heart of the AR8200 Mark 2, ensuring high stability. The TCXO, usually only seen in top of the range desktop models, replaces the crystal reference oscillator commonly used in hand-held receivers. Performance has been significantly improved with the AOR R & D team fine tuning the design for best sensitivity and strong signal handling over the extremely wide coverage of 530kHz to 2040MHz (all mode receive without gaps). The standard aerial has been replaced by a telescopic whip on a swivel base which ensures the best results. A medium wave bar aerial is also supplied. The keyboard Zero and Decimal keys have been swapped in position to match the standard telephone layout, LCD illumination has been improved for better visibility. The four AA-size NiCad batteries have been increased in capacity. Side-mounted navigation keys, rotary tuning control and an alpha-numeric text-comments improve operational efficiency The obvious change has been left for last....... the cabinet color has been changed from green to black!
The all important 8.33 kHz airband channel step is correctly implemented (eight-and-one-third, 33, 66, 00). Channel steps are provided in a menu and may be programmed. Step may be programmed by the operator in any receive mode using multiples of 50 Hz in any mode (i.e. 5 kHz, 12.5 kHz or even 1.25 kHz). Extensive step-adjust and frequency offset facilities are also provided (as per AR5000) to ensure tracking of the most obscure band plans, AFC (Automatic Frequency Control) is included for spot-on tuning ensuring that nothing is missed. A wide frequency coverage is available from 530 kHz to 2040 MHz (no gaps) with actual minimum acceptable frequency of 100 kHz. The RF front-end is preselected around VHF to ensure the highest levels of adjacent channel rejection with software spurii cancellation. The short wave bands are converted directly to an IF of 45 MHz to remove compromise and the AR8200 Series 2 is supplied with a detachable plug in medium wave bar aerial for localised monitoring with a negative feedback circuit employed.
All mode receive: WFM, NFM, SFM (Super Narrow FM), WAM, AM, NAM (Wide, standard, Narrow AM), USB, LSB & CW. A 3.0 kHz SSB filter is employed with true carrier re-insertion resulting in non-offset frequency readout for easy tuning of SSB transmissions. An attenuator and noise blanker are also featured. A meaningful band plan is factory programmed specific to the market area, ensuring that the AR8200 SERIES-2 automatically selects the correct receive mode and tuning step (although mode and tuning step may be manually selected at any time), the band plan may be edited via computer control.
The side keypad provides four arrow keys presented as a single ‘rocker’ resulting in more natural and intuitive navigation through the on-screen menus. Tuning is accomplished via a variety of controls including a side panel indented main tuning dial, arrow keys and keypad. A larger than average back lit LCD with contrast control provides operational data with the ability to add 12 character text comments to each memory channel, memory bank and search bank, a text search feature simplifies identification and recall of stored information. Many text prompts aid operation making programming of search banks etc straight forward. Two frequencies may be displayed along with operating legends and high resolution signal meter and multi-function band scope. The band scope provides adjustable span width from 10 MHz to 100 kHz, you can move the marker, operate peak hold, transfer the marker frequency to VFO and save trace for later recall. The stylish black cabinet has a quality feel with an excellent rear-illuminated keypad with a hard wearing finish.
Flexible dynamic memory bank layout is provided (memory banks may be varied in size between 10 and 90 channels each i.e. bank ‘A’ 80 channels / bank ‘a’ 20 channels with bank ‘B’ 40 channels / bank ‘b’ 60 channels etc). A total of 1,000 memories are provided in 20 memory banks, lockout, select scan, priority and auto store are also provided. In addition 40 search banks are provided with 50 pass channels per search bank and a further 50 for VFO search lockout. Comprehensive edit, move, swap and delete facilities are provided, it is possible to move whole memory search banks. In addition you may write-protect memories, banks and search banks to prevent accidental over-writing of stored data including protection of the entire receiver! Scan & search rates provide a maximum of approximately 37 increments per second. Flash-ROM memory storage ensures that data is automatically saved without the need for a backup battery or capacitor.
Computer control is available via a metallic side mounted robust connector and optional lead. An extensive RS232 command-list is supported. The connector also supports cloning of data between two AR8200 Series-2 receivers, tape output, detector output, mute and AGC. A software package providing frequency control & management, searching, scanning, logging with support for geographic data from a GPS and audio recording to disk is available as a download.
The AR8200 Mark 2 is powered from 4 x AA internally fitted high capacity NiCad cells (supplied), dry cells may be used. External power may also be connected to the charge socket for extended periods of operation (9 - 16V DC).
The Optional Slot Cards which fit into the AR8200 Mark 2 extend the capabilities even further. All this is contained in a case that weighs just 217g excluding NiCads & aerial, or 311g with NiCads fitted. Dimensions are 61(W) x 143(H) x 39(D) mm (excluding projections).
