de Lloyd



This copy from Multipsk MFSK8 using the SDRIQ unit

q Vavtt.......WE2XGR/3 DE WE2XGR/2 GE JOHN. INITIAL RECEPTION LOOKS GOOD. 
INSTANT DECODER LOCKUP TOO, WHICH IS A GOOD SIGN! HW CPY? BKjhn\euMae 
dctin.....WE2XGR/2 DE WE2XGR/3 RR SOLID SIGNAL. YOUR TESTS HAVE COME THROUGH 
WITHOUT ERROR. RUNNING USUAL 3ØØ WATTS HERE...TUNING IS A BIT OFF, BUT NO 
ICE. GUESS WINTER IS HERE. HW? BKorypdðSmAyFdxotb
xs bt7ia..WE2S®R/3 DE WE2XGR/2 R FB JOHN AND SOLID COPY. INITIAL PROBLEM 
LOCKING UP ON FIRST FEW CHARACTERS BUT QUICK RESYNC. RUNNING 4ØØ WATTS AS 
USUAL. TEMP 23 DEGREES F WITH FREEZING RAIN AND SLEET. MUST BE BUILDING UP 
ON TOP HAT AS I HAVE TO RETUNE EVERY HALF HOUR OR SO. SURE NICE TO HAVE 
REMOTE TUNED VARIOMETER!!! NO TRIPS OUT TO THE ANTENNA FOR TUNING - JUST 
IMPEDANCE CHANGES. HW? BKl )ch2«o#o{.....XGR/2 DE XGR/3 RR YES, SYNC TIME 
APPEARS TO BE BETTER THAN WITH DOMINO. SOUNDS SIMILAR, THOUGH! TAKES A LOT 
OF ICE TO BOTHER THE LOOP HERE...THE RESISTANCE APPEARS TO HAVE DROPPED WITH 
THE COLDER WX, AND I NEED TO REJUGGLE THE XFRMR. I DO ENJOY THE TRIP OUT IN 
THE FRESH AIR, THOUGH - HI. STILL HAVE THE VACUUM VARIABLE THAT I GOT LAST 
FALL, SO WILL PROBABLY MATE THAT WITH A MOTOR ONE OF THESE DAYS. THAT WHOLE 
TUNING SETUP SHOULD BE REDONE FOR EASY SWITCHOVER BETWEEN BANDS. ANY BIG 
FADES YET? /2 DE /3 BKÄ ól it  MtlPAci..ip.WÞeohGRzaieDE WE2XGR/2 RR AGREE 
SYNC TIME BETTER THAN DOMINO. YOU WENT THROUGH A GOOD FADE AND NO MISSED 
CHARACTERS. SEEMS ERROR CORRECTION HELPS FOR SURE. MODES WITHOUT IT WILL 
SUFFER MORE MISSED CHARACTERS. GUESS ITS TIME TO CHANGE OVER TO PSKFEC31 SO 
WHY DON"T YOU MAKE THE SWITCH ON YOUR NEXT TRANSMISSION...XG


This copy from Multipsk PSKFEC31 with the SDRIQ

Ø....WE2XGR/2 DE WE2XGR/3 RR FB COPY JAY. NOW IN PSKFEC31 MODE. NO REAL 
FADES IN YOUR LAST MESSAGE, SO NO BIG TEST OF DEGRADED COPY HERE. WILL BE 
INTERESTING TO SEE ANY REPORTS FROM THE GANG. YES, I REALLY THINK THAT WE 
NEED THE FEC FOR GOOD PERFORMANCE BOTH HERE AND ON 137. OF COURSE, IT DOES 
PULL DOWN THE DATA RATE, BUT AT LEAST UP HERE, WE'VE GOT BETTSA SNR TO E8EEA 
RATE. WOULD BE INTERESTIOG TO SEE SOME OF THESE COMPARISONS AT 137. HW COPY? 
XGR/2 DE XGR/3 BK T. ...WE2XGR/3 DE WE2XGR/2 RR FB JOHN. SOLID COPY AS 
EXPECTED. THERE NEVER SEEMS TO BE ANY WORRY THAT PSKFEC31 WILL SYNC UP. 
SEEMS LIKE IT'S ALWAYS RIGHT THERE. SPEEDS APPEAR TO BE QUITE SIMILAR...AS 
FH AS I CAN TELL. YOU TOOK A COUPLE GOOD DIVES AND I MISSED JUST A FEW 
CHARACTERS. CERTAINLY NOT ENUFF TO AFFECT THE MESSAGE. NOT SURE HOW MUCH ICE 
WE'RE SUPPOSED TO GET TONIGHT SO I MAY HAVE TO LOWER THE TOP HAT LATER THIS 
EVENING. GUESS THAT'S ONE MORE ADVANTAGE OF THE LOOP! HW COPY? 
B.....WE2XGR/2 DE WE2XGR/3 RR AGAIN SOLID. YOU KNOW, IT WOULD BE INTERESTING 
TO HAVE THIS SORT OF ERROR CORRECTION IN A LITTLE SLOWER DATA RATE, MAYBE 1Ø 
BITS/SEC. WOULD BE A LITTLE STODGY, BUT MIGHT HAVE REAL POTENTIAL AT 137. 
THE MFSK8 MODE DOES HAVE ONE ADVANTAGE FOR EMERGENCY COMMUNICATIONS IN THAT 
IT HAS LOWER CASE CHARACTERS, WHICH THIS ONE DOESN'T. WX EXPECTED HERE HAS A 
LITTLE MORE SNOW, BUT STILL WITH A CHANGEOVER...MAN, I'M GLAD I DON'T HAVE 
TO LOWER THAT LOOP OF MINE! HW COPY? BK......WE2XGR/3 DE WE2XGR/2 RR SOLID 
COPY EVEN THROUGH SEVERAL DEEP FADES. OKAY ON LOWER CASE LETTERS - DIDN'T 
THINK ABOUT THAT BUT IT MAY BE IMPORTANT. THIS LOOKS TOO MUCH LIKE AN OLD 
TELEGRAM HI! YES, I'M SURE LETTING YOUR LOOP DOWN WOULD BE AN ORDEAL. 
DROPPING THE TOP HAT IS NOT THAT BAD. I HAVE ROPES AND PULLEYS - ONLY TAKES 
ABOUT FIVE MINUTES. ANYWAY, GUESS WE'VE ACCOMPLISHED OUR TEST FOR TONIGHT. 
HOPE WE HAVE SOME LISTENERS THAT WILL SEND THEIR REPORTS. I'M THINKING THAT 
THE MFSK8 WIL MAKE A GOOD ACCOUNTING OF ITSELF...WE'LL SEE. 73, GE AND 
THANKS FOR THE QSO. WE2XGR/3 DE WE2XGR/2 BK
 XGR/2 DE XGR/3 RR SOLID AGN, JAY. THE BEST WAY TO LOWER THIS LOOP WOULD BE 
WITH A CHAIN SAW! TNX FOR THE QSO, AND WE'LL PROBABLY HAVE TO DO SOME BEACON 
TESTS TO REALLY PROVE THE WINNER. 73 AND GE. WE2XGR/2 DE WE2XGR/3 GE

> MFSK8 and PSKFEC31 are available in F6CTE's MultiPSK. MFSK8 decoders may
