[VHFcontesting] The digital modes and the Sept contest....

[Steve (K1IIG)]

Hello Keith,
I do not find your comments offense in the least. Not being a digi guy, I found it informative. The most interesting comment was
"CW can also be copied by ear at lower signal levels then FT8 can reliably and repeatably decode.
FT8 does nothing 'better''.

I thought FT8 and other digital modes could copy well below the noise that CW could not copy.

This is gonna cause flames to erupt, but so be it...not the first time.
Since this is a VHF CONTESTING mail reflector, I don't think anybody should
be too offended.  If you are....well....

Marshall, the whole 'funny little numbers' thing is the result of the now
complete take-over of the WSJT program by HF-centered operators.  This
trend has been going on for a number of years and, with the release of -X
version of the program, the days of WSJT being the work of EME and weak
signal guys is over.  It's obviously true when you actually have to go into
SETTINGS to enable those quaint and useless to most "VHF/UHF FEATURES" and
even more useless "CONTEST MODE".  Read the posts on the WSJT mail
reflector and note that you're a 'bad guy' if you dare to run high power
with JT65 or FT8.  I'll bet you VHF ops didn't know that the 'rule' of WSJT
modes is that they are 'low power' modes !  I'll bet the original JT65 EME
users didn't realize they were supposed to be QRP.

This is why you see default settings of JT65 to be nothing like the
original, EME-centered, versions.  JT65 was hijacked, changed, found to be
lacking for HF and cast off.  But the 'funny little numbers' remain.
Everybody is supposed to use QRA64 for EME now - didn't you get the memo ?
(j/k).

HF users of WSJT-X outnumber "us" by 10 to 1 (probably more).  Anything
related (and better for) VHF is but a side note.

A comment to another post on here - WSJT & Digital operation is NOT a Brave
New World of contesting.  Many of us have been using digital meteor scatter
modes (FSK441 and now MSK144) for years and years to improve our scores.
Also an occasional QSO on JT65 and ISCAT where things are REALLY weak.  The
whole explosion of WSJT-X by HF centered ops has just thrown it into the
harsh light of day.  MSK144 for meteors and JT65 for ultra weak and
constant signals are PROPER uses of the digital modes during a contest.
FT8, while interesting and useful, is not a 'proper' mode for contesting.
One can work QSOs much faster on SSB or CW and, from what I can see after
using FT8 for several months during 6M E season, CW can also be copied by
ear at lower signal levels then FT8 can reliably and repeatably decode.
FT8 does nothing 'better'.  The goal of contesting is to create score - a
higher score can be created using modes other then FT8.  FT8 is an adjunct
to SSB/CW, not a means to an end.  Remember that the next E opening when
50.313 is QRMed to death and 50.080 through 50.200 is a wasteland of noise.
