THE BEST MODE FOR LOW POWER WORK, I HAD TO GIVE IT A TRY.  I LOADED UP THE
MMSSTV SOFTWARE, CONFIGURED IT TO COMMUNICATE WITH THE 705, AND THEN SENT
AN SSTV CQ.  MY 5 W 20 METER SIGNAL WAS RATHER NOISY AT KD9DD IN ILLINOIS,
BUT MY CQ IMAGE WAS VIEWABLE SEE FIGURE 4.  THE WIRELESS CONNECTION THIS IS
THE ERA OF WIRELESS MOBILE DEVICES, AND THE IC 705 IS NO EXCEPTION.  IT
INCLUDES WI FI FUNCTIONALITY AS STANDARD EQUIPMENT.  THIS MEANS THE IC 705
CAN CONNECT TO ANY 2R4 GHZ WIRELESS NETW
RECEIVE SWITCHING USES A RELAY, AND CLICKING IS AUDIBLE, BUT NOT REALLY
NOTICEABLE IF YOURE SENDING WHILE LISTENING TO THE SIDETONE.  LIKE THE IC
7300, THE IC 705 FEATURES A VERSATILE AUDIO RECORDER.  WITH A MICROSD
MEMORY CARD INSTALLED, THE 705 WILL CREATE AUDIO FILES EACH TIME YOU START
RECORDING YOU CAN START RECORDING RECEIVED AUDIO ALMOST IMMEDIATELY THROUGH
THE FRONT PANEL QUICK MENU.  EACH AUDIO FILE IS LABELED WITH THE DATE,
TIME, FREQUENCY, AND OPERATING MODE.  YOU CAN REPLAY THE FILES THROUGH THE
RADIO OR LOAD THEM INTO ANOTHER DEVICE.  HF DIGITAL ANOTHER SIMILARITY
BETWEEN THE IC 705 AND THE IC 7300 IS THE FUNCTIONALITY AVAILABLE THROUGH
ITS USB PORT FOR HF DIGITAL OPERATING AND COMPUTER AIDED TRANSCEIVER CAT
CONTROL.  IF YOU ENJOY DIGITAL OPERATING WITH MODES SUCH AS FT8, THE IC 705
MAKES THIS AS EASY AS POSSIBLE NO EXTERNAL INTERFACES OR SOUND DEVICES
REQUIRED.  YOULL NEED TO PROVIDE YOUR OWN MICRO USB CABLE TO CONNECT THE
TRANSCEIVER TO YOUR COMPUTER, BUT AS THE MANUAL WARNS, DONT CONNECT THE IC
705 STRAIGHTAWAY THERE ARE TWO WINDOWS COM PORT DRIVERS THAT MUST BE
INSTALLED ON YOUR COMPUTER FIRST.  AT THE TIME OF THIS WRITING, ICOM
OFFERED ONLY WINDOWS DRIVERS.  YOU MUST DOWNLOAD THE DRIVER INSTALLATION
PACKAGE FROM THE ICOM SUPPORT SITE, EXTRACT THE FILES, AND THEN RUN THE
SETUP APPLICATION, CHOOSING EITHER 32 OR 64 BIT.  I INITIALLY TRIED USING
AN OLDER LAPTOP BUT DISCOVERED THE ICOM DRIVERS WERE INCOMPATIBLE WITH ITS
WINDOWS 8R1 OPERATING SYSTEM.  THIS MAY HAVE BEEN DUE TO AN ISSUE WITH THE
OLD LAPTOPS CONFIGURATION.  ON MY WINDOWS 10 DESKTOP PC, THERE WASNT A
PROBLEM.  THE DRIVERS CREATE TWO SEPARATE COM PORTS, AND YOULL NEED TO OPEN
THE WINDOWS DEVICE MANAGER TO SEE WHICH NUMBERS WINDOWS HAS ASSIGNED TO
THEM.  ONE IS FOR ICOM CI V COMPUTER AIDED TRANSCEIVER CAT CONTROL AND THE
OTHER PORT IS USED FOR OTHER APPLICA LAB NOTES ICOM IC 705 BOB ALLISON,
WB1GCM THE ICOM IC 705 HAS PLENTY OF DYNAMIC RANGE FOR USE IN THE FIELD OR
A HOME STATION.  AT 14 MHZ, WITH THE PREAMP OFF AND 2 KHZ SIGNAL SPACING,
ITS LOWEST DYNAMIC RANGE IS 90 DB TWO TONE, THIRD ORDER IMD.  THIS
PERFORMANCE IS VERY GOOD.  BLOCKING DYNAMIC RANGE BDR AND RECIPROCAL MIXING
DYNAMIC RANGE RMDR WERE QUITE GOOD AS WELL, AT 124 AND 110 DB,
RESPECTIVELY.  THE ONLY POTENTIAL PERFORMANCE ISSUE MAY SURFACE WHILE
OPERATING ON THE 2 METER BAND, WHERE SECOND ORDER PRODUCTS MAY OCCUR IF THE
OFFENDING SIGNALS ARE STRONG ENOUGH.  SECOND ORDER PRODUCT IS A PHANTOM
