ADVENTURES IN RADIOLAND
BE ALL THAT YOU CAN BE!!!

HI... I'M JIM-KC9VKV... AND THAT'S WHAT OUR QSO-VLOG NETWORK IS ALL ABOUT... HELPING PEOPLE ACHIEVE THE BEST SOUNDING STATION POSSIBLE!!!... THANKS FOR DROPPING BY!!!...

F.Y.I... MY BACKGROUND IS 50 YEARS IN COMMERCIAL BROADCASTING... WHERE A LOT OF BIG BUCKS ARE SPENT ON AUDIO PROCESSING EQUIPMENT... AND GETTING IT SET UP CORRECTLY... TO GET THE LOUDEST... BEST SOUNDING STATION POSSIBLE!!!...

WELL... WHEN I BECAME A HAM RADIO OPERATOR... I COULD HEAR IMMEDIATELY A LARGE DISCREPANCY IN "ON AIR" TECHNICAL PROFICIENCY!!!... A LOT OF STATIONS WERE RUNNING WITH VERY POOR MIC EQUALIZATION... VERY MUDDY... WITH LITTLE ARTICULATION!!!... AND AS I CONTINUED TO WORK STATIONS... I REALIZED MOST OF THE STATIONS WERE ALSO RUNNING WITH VERY LOW AVERAGE PEAK MODULATION... MANY AROUND 30% OF AVERAGE PEAK MODULATION!!!...

SO WITH MY BACKGROUND... I FELT I COULD HELP... OR AT LEAST TRY!!!... I KNEW THAT MOST MODERN DAY HAM TRANSCEIVERS DID HAVE ENOUGH ON BOARD PROCESSING EQUIPMENT TO BE ABLE TO OVER COME MOST ALL OF THE PROBLEMS... SO IT WOULD JUST BE A MATTER OF DEVELOPING A GENERIC DYNAMIC RANGE SET UP PROCEDURE... AND THEN ADJUSTING THE ON BOARD E.Q. GEAR!!!...

AND SO TODAY... OUR MISSION STATEMENT FOR THE QSO-VLOG NETWORK IS...
TO ESTABLISH A HIGHER TECHNICAL LEVEL OF RADIO TRANSMISSIONS OF THE HUMAN VOICE... BY THE INTELLIGENT UTILIZATION OF AVAILABLE ELECTRONICS IN CURRENT AMATEUR RADIO TRANSCEIVERS!!!... OUR TRANSMITTER SET UP... WHILE GENERIC IN NATURE... CONVERTS THE AVERAGE 10 DB DYNAMIC RANGE TRANSMITTER... WITH AN AVERAGE 30 PERCENT OF PEAK MODULATION... TO A MUCH FULLER 3 DB DYNAMIC RANGE... WITH AN AVERAGE 80 TO 85 PERCENT OF PEAK MODULATION!!!... THIS SUBSTANTIAL BOOST IN AUDIO TRANSMIT LEVEL IS EXTREMELY BENEFICIAL IN HIGH NOISE LEVELS... AND HEAVY QRM!!!... IT ALLOWS YOU TO PUNCH THROUGH... WHEN OTHERS FAIL!!!...

SOME TRANSMITTER SETUP NOTES:
WE SUGGEST RUNNING COMPRESSION ON... AT A 3 (0-10 SCALE)...
OR 30 (0-100 SCALE)... JUST A THIRD OF THE COMPRESSOR'S CAPABILITY!!!...

THEN ADJUST YOUR ALC METER TO READ MID-SCALE TO 2/3RDS BY ADJUSTING YOUR MIKE GAIN CONTROL AS YOU SPEAK THE WORD "AUDIO!!!"...

THE SECOND PART OF OUR TRANSMITTER SET UP... HAS TO DO WITH PROPER MIC EQUALIZATION!!! WE OPTIMIZE THE TRANSMITTED VOICE FOR A HIGHER DEGREE OF INTELLIGIBILITY... THROUGH THE USE OF E.Q. PATTERNS THAT BRING OUT THE ARTICULATION ASPECTS OF THE HUMAN VOICE!!!...

MODERN DAY HAM TRANSMITTER AUDIO EQUALIZERS ARE DESIGNED TO STRIKE A BALANCE FROM THE TOP OF THE AUDIO RANGE TO THE MIDS... AND FROM THE BOTTOM OF THE AUDIO RANGE TO THE MIDS,... SO DO NOT PUSH THE MIDS!!!... (400 TO 1.6KC)... LEAVE THIS PART OF THE SPECTRUM "FLAT"!!!...

THIS IS SO IMPORTANT THAT THE ICOM 7300 AND ICOM 7610 BY DESIGN... DON'T EVEN PUT A MID RANGE CONTROL IN THEIR EQ...
F.Y.I.... YOUR EQ PUSH/CUT POINTS SHOULD BE... 200 CYCLES FOR BASS...
AND 2.7KC FOR TREBLE... AT A BANDWIDTH OF 4 IF YOUR EQ CONTROL ALLOWS FOR SHAPING!!!...
ALSO MAKE SURE YOUR TRANSMITTER BANDWIDTH (TBW) IS SET TO "WIDE"!!!... (1OO TO 2900) OR TO THE TRANSMITTER'S "BEST" PERFORMANCE SETTING!!!...

OVER THE PAST SIX YEARS... WE'VE HELPED A LOT OF FOLKS SET UP THEIR TRANSMITTERS... AND WE RECORD THE PROCESS... SO WHEN THEY LATER HEAR THEIR RECORDING... THEY CAN HEAR WHAT THEY SOUNDED LIKE IN THE BEGINNING... AND THEN WHAT THEY SOUNDED LIKE IN THE END... AFTER BEING SET UP!!!... BUT THE BEST PART IS... THEY CAN HEAR WHAT EACH ADJUSTMENT PROCEDURE DOES ALONG THE WAY... AND THUS... IT BECOMES A VERY EDUCATIONAL EXPERIENCE!!!... AND SO THEY BECOME MUCH MORE PROFICIENT AT OPERATING THEIR OWN EQUIPMENT!!!..

TODAY... WE'RE CURRENTLY FEATURING OVER 3400 QSO-VLOG AIRCHECK RECORDINGS... WHICH CAN BE ACCESSED ON YOUTUBE AT...
