INTERNAL EMBEDDED PC, JUST LIKE THE OTHER ANAN TRANSCEIVERS.  AN AIR
GAPPED SYSTEM WITH NO CONNECTION TO THE OUTSIDE WORLD IS OF INTEREST
TO MILITARY AUXILIARY RADIO SYSTEM MARS OPERATORS WHO MAY NEED
ADDITIONAL SECURITY FROM INTERNET INTRUDERS.  A USB DRIVE WOULD BE
NEEDED TO INSTALL ADDITIONAL SOFTWARE OR TRANSFER FILES.  THE
7000DLE INTERNAL PC CAN BE CONNECTED TO A LAN AND THE INTERNET VIA
WI FI, AND IT CAN BE ACCESSED BY OTHER EQUIPMENT IF NECESSARY.  THE
COMPUTER WOULD HAVE T THE UNIT COMES WITH THE SOFTWARE NEEDED TO RUN
THE SDR ALREADY INSTALLED, SO THE UNIT IS READY TO USE OUT OF THE
BOX.  AS TESTED HERE, THETIS SOFTWARE VERSION 2R7R0 AND METIS
FIRMWARE VERSION 2R0 HAVE BEEN INSTALLED.  THETIS/METIS IS ALSO
KNOWN AS PROTOCOL 2 AND IS THE LATEST GENERATION FIRMWARE AND
SOFTWARE AVAILABLE FOR THE APACHE LABS ANAN SERIES SDR TRANSCEIVERS.
I WAS A LITTLE SKEPTICAL THAT 128 GB IS SUFFICIENT STORAGE, BUT WITH
TWO SDR SOFTWARE VERSIONS AND MANY THIRD PARTY HAM RADIO AND MARS
MILITARY AFFILIATE RADIO SYSTEM APPLICATIONS LOADED, MY USAGE IS 48
GB.  THERE SHOULD BE PLENTY OF ROOM FOR WORD PROCESSING,
SPREADSHEET, AND OTHER APPLICATIONS, BUT ANYTHING WITH A VERY LARGE
DATABASE MIGHT BE A CHALLENGE.  BECAUSE THE UNIT HAS THE CAPABILITY
OF WI FI AND ETHERNET LAN CONNECTIONS, EXTERNAL STORAGE IS ALWAYS
AVAILABLE.  THE APACHE LABS ANAN SERIES RADIOS, INCLUDING THE ANAN
7000DLE MKII, HAVE THE FOLLOWING MAJOR SUBSYSTEMS 1 THE MECHANICAL
AND ELECTRICAL CHASSIS, INCLUDING A HEATSINK AND FANS, WITH
PROVISIONS FOR EXTERNAL FANS.  2 THE RF BOARD CONTAINING THE ANALOG
PARTS OF THE RECEIVER AND TRANSMITTER, THE POWER AMPLIFIER, AND THE
FILTERS.  THE NEW RF BOARD IN THE 7000DLE MKII OFFERS BETTER
RECEIVER DYNAMIC RANGE AND BETTER TRANSMIT PURE SIGNAL PRE
DISTORTION SUPPORT THAN PREVIOUS HARDWARE.  PURE SIGNAL
SIGNIFICANTLY IMPROVES THE TRANSMITTED IMD PRODUCTS, AS DISCUSSED IN
THE LAB NOTES SIDEBAR.  3 THE DIGITAL BOARD WITH A FIELD
PROGRAMMABLE GATE ARRAY FPGA TO PERFORM ALL THE DIRECT UPCONVERSION/
DOWNCONVERSION DUC/DDC AND DIGITAL SIGNAL PROCESSING DSP FUNCTIONS.
IN THE 7000DLE MKII, IT IS AN ORION II BOARD.  4 THE SDR FIRMWARE
FOR THE DIGITAL BOARD METIS.  5 THE SDR SOFTWARE FOR THE PERSONAL
COMPUTER THETIS.  APACHE LABS MANUFACTURES THE TRANSCEIVER HARDWARE,
BUT OPEN SOURCE DEVELOPERS CREATE THE FIRMWARE AND SOFTWARE, WHICH
IS FREELY AVAILABLE FOR ANYONE TO USE OR ADAPT.  THE FIRMWARE IS
SPECIFIC TO THE DIGITAL BOARD USED IN THE TRANSCEIVER, WITH VERSIONS
CALLED HERMES, ANGELIA, ORION, AND SO ON.  THE SOFTWARE IS COMMON TO
ALL THE ANAN SERIES TRANSCEIVERS.  THIS ARTICLE WILL FOCUS ON
IMPROVEMENTS IN THE HARDWARE WITH THE ANAN 7000DLE MKII AND THE
PROTOCOL 2 SOFTWARE/FIRMWARE.  HARDWARE INSTALLATION THE ANAN
7000DLE MKII REQUIRES A USER SUPPLIED MONITOR HDMI AND USB KEYBOARD
AND MOUSE FOR OPERATION WITH THE INTERNAL PC MODULE.  I USED A
WIRELESS KEYBOARD/ MOUSE FOR TESTING, BUT WIRED UNITS WILL WORK FINE
TOO.  A USB HUB MAY BE REQUIRED IF ADDITIONAL USB DEVICES ARE USED.
IT IS TOO BAD THAT A FRONT PANEL USB
