PROCESS DIGITAL DATA AS ENCODED AUDIO SIGNALS.  OPERATING FROM A REMOTE
LOCATION REQUIRES THE TRANSMISSION OF THE COMPUTER AUDIO TONES TO AND FROM
THE REMOTE LOCATION, TO SWITCH BETWEEN TRANSMIT AND RECEIVE AS WELL AS
BEING ABLE TO TUNE THE TRANSMITTER.  BRUTE FORCE ISNT ALWAYS THE ANSWER AS
SUGGESTED BY THE LITERATURE, I TRIED BRINGING THE AUDIO BACK HOME VIA THE
INTERNET PROTOCOL VOIP.  THE RESULTS WERE DISAPPOINTING.  AUDIO IS NO
LONGER TRANSPORTED AS AN ANALOG SIGNAL EVEN IN OUR TYPICAL PHONE NETWORKS.
ITS DIGITALIZED AND PROCESSED IN ORDER TO GET THE BEST RESULTS FOR THE
HUMAN EAR LISTENING TO HUMAN SPEECH NOT FOR DIGITAL MODE PROCESSING
SOFTWARE.  THE SAME HAPPENS WITH VOIP, WITH MORE DISTORTION AND DELAYS AS
THE SIGNAL IS FRAGMENTED IN PACKETS TO TRAVEL ON THE INTERNET.  AS A
RESULT, PSK CANNOT BE DEMODULATED AT ALL, AND THE MOST ROBUST MODE, OLIVIA,
NEEDS VERY STRONG SIGNALS TO COME THROUGH.  AS AN EXPERIMENT, TRY TO HAVE A

A REMOTELY CONTROLLED STATION FOR HF DIGITAL MODES A REMOTE SSB STATION
ISNT TYPICALLY THE BEST FOR DIGITAL MODES.  HERES WHY AND HOW TO MAKE IT
ALL WORK.  DANIEL CRAUSAZ, HB9TPL I AM A CITY DWELLER WITHOUT THE ABILITY
TO HAVE EFFECTIVE HF ANTENNAS, PARTICULARLY FOR THE LOWER BANDS.  THE
CHALET THAT I OWN, LOCATED IN THE ALPS, OFFERS A MUCH BETTER OPPORTUNITY
INCLUDING A FEW COOPERATIVE TREES SUPPORTING A DOUBLE L, A HALF SQUARE AND
TWO LAZY H ANTENNAS.  THEY, ALONG WITH MY OLD TEN TEC OMNI VI HF
TRANSCEIVER, HAVE ALLOWED ME SOME GREAT NIGHTS ON 40 OR 80 METERS DXING AND
CHATTING IN DIGITAL MODES SUCH AS PSK, MFSK OR OLIVIA.  UNFORTUNATELY, THE
CHALET IS A 1 1/2 HOUR DRIVE FROM HOME PLUS A 2 MILE WALK IN WINTER,
RESTRICTING MY ACTIVITY TO A COUPLE OF WEEKENDS THAT, UNFORTUNATELY FOR ME,
HAPPEN TO BE CORRELATED WITH RTTY CONTESTS.  A QST ARTICLE BY LARRY PHIPPS,
N8LP, GAVE ME THE IDEA TO HAVE A PARTICULARLY LONG CABLE CONNECTING MY HOME
PC TO THE TRANSCEIVER A 100 MILE TELEPHONE LINE.  THE REMOTE HF DIGITAL
MODES STATION A STATION DESIGNED FOR HF DIGITAL MODES CONSISTS OF A
