Re: FT8 performance (or, lack of) on 432

John, sometimes one signal, sometimes 2.  I'm familiar with what aircraft look like on 432 beacons and this is sure what I remember.  Good idea about FT4.  The guys I couldn't work were NOT weak - FT4 would have done it easily.

And yes, the old standby of CW would solve all problems but good luck with getting the 'new breed' to QSY to that mode.  They won't even go to SSB...

I don't know enough about ISCAT to guess about the utility of that,
but...don't shoot...have you considered FT4?  The TX period is nearly 3x
shorter, and tone spacing about 4x that of FT8.  This suggests the
decoder could be a lot more tolerant of frequency drift, if you can live
with the S/N penalty.  At that point you're probably also in the
ballpark of being able to use CW, right?

Well, there is a major E-W flight path between you and Phoenix.I guess you probably have planes on that path one way or another every 10 minutes or so. If you look at the slope of the frequency shift and know the frequency, you should be able to calculate the velocity of the aircraft pretty accurately.

I'm thinking a mode such as ISCAT (specifically ISCAT-A, which was designed for microwave rain scatter paths) might be a vastly superior mode for this situation.  FT8 certainly sucks wind under these conditions and proved it repeatedly today.

I have verified to the best of my ability that my system is stable.  My transverters are reference locked to GPS and I have another, independent, reference locked source which I can monitor on the air at whatever frequency I set it to.  I have also completed at least one 432 Q on FT8 that showed no 'drift'.  Evidently there are fewer aircraft on this path (DM58 to SLC area) or they are moving on a course which does not cause Doppler shift on any reflection.

222+ contest this weekend

Keith Morehouse
 

Anyone planning on running WSJT modes this weekend need to remember that WSJT-X FT8 mode does not play well with the required 6 character grid square report REQUIRED for distance scoring in thai contest.

As a work-around, you can select the CONTEST MODE exchange for the EU VHF contest and simply ignore the serial number generated.  Your exchange will be a 6 character grid, but you will still be CQing with a 4 character square.

For meteor scatter on 222, most of us western ops are using the older FSK441 mode, which requires the "pre-X" version of WSJT.  WSJT 9.7 is the version of choice for most of us.  Even with that version, you will need to manually edit your grid in the message template box to send the required 6 character report.

Re: CQ WW VHF Result

Like just about everybody, I experienced rapid fading throughout the contest that made most of the FT8 QSOs a real struggle. Or not complete at all. Many others have suggested that getting ops off 50.313 was needed for these conditions, but we just couldn't seem to get a critical mass. I was monitoring and calling on SSB and FT4 with very little success. This was certainly not the case for the June contest, perhaps because propagation was clearly much better and activity higher.

NM stations worked: AA5B, WD5COV, AA5PR/R in DM63, KC7QY, and possibly KK6MC. QSB prevented me from hearing an acknowledgement of my RRR on FT8, but I logged it anyway.

163 QSOs, 104 grids, 16,952 points claimed. Single band, low power.

Same setup as in June: 6M5X on 15 ft mast in front yard. Armstrong rotor. Had two extended shutdowns for T-storms, but such is life in Florida.

Not the best of times but an interesting time none-the-less. Started out in the hole, had a video conference that was supposed to end at noon local, went over by about 20 minutes. Quick lunch and then on the air. Had WSJT talking to N1MM+ on Friday. Communications failed Saturday morning. When I did get on I checked SSB and CW first. Heard two weak CW stations but no  contacts. Went to FT8 and found really tight spotlight prop. 7 of the first 9 Qs were in EM34/35. Slogged along most of the day with few decodes breaking +0. Conditions went up and down very rapidly,had stations call at +15 and the next call at -10. Saturday afternoon I got shutdown by a slow moving T-storm (didn't get enough rain to care about but lots of lightning). 

Had 2M on all day Sunday and never heard anyone. Disappointed with MSK Sunday morning, just one AZ QSO. Continued with FT8 and a single FT4 through Sunday. Late Sunday had another spotlight opening but this time into North Florida. Whole flock of CM89/89/98/99, etc with a few EM60's in between. That included our friend Mike, WB2FKO, in EM89. Missed John up in DM67 on Saturday, one decode only but did get him in the log on Sunday from DM63.

Highlight was my only new grid, 15 minutes before the contest end with W8ZN in EM87. Better yet, he's gong to put his Qs up on LoTW.

Half the battle was just keeping equipment and operator cool enough to get through the weekend.  The only major failure was the battery booster, which popped under the stress Saturday afternoon.

Propagation on 6 m was in and out, but overall pretty good.  I need to remind myself to occasionally look at the S-meter to accurately judge signal strengths when in low-noise locations, but it seemed that there was often plenty of margin for SSB (or FT4, at least) yet people were pretty seriously stuck to FT8.  I had to work for exactly 1 SSB contact.  He seemed grateful too.

The high points of the contest for me included:

Every contact I had on 2 m
Working K7KQA (who was hoping for DM76),  Mike WB2FKO in Florida, and an EA8 station
Seeing for the first time the canyon that the Canadian River flows through east of Wagon Mound

Total contacts 124, multipliers 87, score 11,397.

CQ WW VHF comments

All-in-all it was a wretched weekend for rovering in S.E. Colorado.
But, there were several bright spots -- among them was working two
NM VHF Society ops:

John, AA5PR/R -- twice on 2M CW from each of DM88 and DM87
Arne, N7KA -- on 6M PH from DM88 -- good sig / short skip

Except for the first 60 minutes of the contest, propagation was crap.

Hot, hot, hot -- with elevated humidity.

If the memory of this last weekend wears off soon enough,
I may do it again.

 Chasing rovers is fun. Big TNX to AA5PR/R.  I always  seem to find him, especially on 2m CW.  I’ve got a whopping 12 grids on 144, and 5 are attributable to his roving.  Another effort this weekend from the K5TA rover-simulator.  Someday I’ll drop the “-simulator.”

My plans for this weekend are pretty simple:

DM76va Saturday 1800-0100Z (maybe later if I'm being productive)
DM63qv Sunday 1400-2100 Z

6m 100 W + Moxon
2m 100 W + 6 el.

All modes.

I'll occasionally point towards ABQ/SF/El Paso with CW/SSB on 144.2  and FT8 on 144.174.

I thought there may be some 6m ops on the list looking to work Alaska (KL7).

I will be on with 3-element yagi pointed to the West Coast of the US running
80w on 50.313 (900-Hz) FT8.  I will be using "Contest Mode" which
exchanges four-digit grid squares instead of signal
report.  <https://www.cqww-vhf.com/>https://www.cqww-vhf.com/

Normally run even (first) sequence to work West Coast that normally
are on odd (second) sequence.  But either sequence OK as I will adapt.

Opening last Sunday netted several stations in Pac NW for me.  But I

Folks,

After a little "prodding" from a local ham, I'm contemplating a portable
operation from EM87 in the CQ VHF contest coming up. EM87 appears to be a
much needed grid and It's been 35 years since I was there last, back when
we first went to grid squares I was there for a 6m sprint as WD8ISK. I will
have a kw on both bands and will operate SSB, CW and digital.

Let me know if you are interested and please pass this on to your
respective groups that I might not be a member of.

Wonderful job again Duffey!  Thanks for doing this as it brings great value to those who strive to do well in the contest.

We are fortunate in NM to have you, along with Bruce and Scott authors of the awesome SS-SSB coverage, who put in a lot of time and effort on these contest summaries.  While it's hard to believe, uninformed hams (they can't count pages apparently) think there is too much contest coverage in QST now!  I think the additional coverage on the Web is appropriate and greatly appreciated.  Reading that coverage should be part of everyone's contest preparation checklist.

While not VHF and above, I hope to work many of you in the IARU HF Championship Contest this weekend.

Re: 2020 JAN VHF

Thanks for the nice words Bruce. I think it hard to talk about the impact FT8 has had on the January VHF contest without some background, and that background grew into history. That picture of K1JT as a very young K2ITP was too good not to include.

Scott and Bruce’s write ups are excellent and contain a lot of data which is interesting to study and is helpful in planning one’s sweepstakes efforts. Highly recommended reading. 

I had thought about going into the discussion of encouraging different modes with different point structures, but there are a lot of layers to that discussion and I couldn’t really put forth a succinct discussion without a lot of caveats and equivocating, so yeah, a stand alone discussion for later. We could start one here.

Re: 2020 JAN VHF

Jay, thanks for the kind words. I have contemplated doing a subset of this article with the activity data for the Contest Update e-mail newsletter or National Contesting Journal.  I think I would need to beef it up with data from the other contests though and that is going to take some more effort. 

When the results writeup was done in print, there was a  page limit, which limited how much stuff could be in print and it is likely that at least most of the data related to the activity trends would have to have been left out and would end up on the web anyway. 

Anyway, I am looking into how the data can get a wider distribution.

I know I sent you a direct message Duffey, but I too agree that this was an excellent write up.  It is a travesty that this information is NOT included in the print version of QST.  A wealth of information and a lot of great data showing positive activity trends and band/mode utilization.  Great summaries like this NEED to be out in the public eye to generate more activity for all of us to benefit from.

Well done my man.   Coffee or drink of choice on me at Yuma 2021!  (Fingers crossed).

Thanks Mike, I appreciate the comments and they are well received here. Some times when I get bogged down writing these things I get discouraged and comments like yours make it all worthwhile.

I wanted to write a bit on how the use of FT8 has changed the contest, but I realized that I could not do that without writing about the history of the contest and how it has changed over the years. So, that was how that all came about.

When I first started roving I spent a long time studying various VHF propagation modes, particularly with regards to contesting. That led me to Joe’s article on using scatter to make more contacts at greater distances in the VHF contests. That article, though quantitative, still contains information that is useful today. Anyway, looking at past contest results as part of that I found the picture of 16 year old Joe and how he and his brother really changed VHF contesting. I filed that away for future use and that time finally came. It all fits together nicely, puts WSJT into perspective, and I think most importantly, it shows that it is not a recent development, but is obviously a result of Joe’s early experience in contesting.

With the quarantine at ARRL HQ, finding a copy of the picture suitable for the article turned out to be an effort for the editors.

Again, thanks for the kind words. - Duffey
