Re: NM grids on 6M

Keith Morehouse
 

That would be great, John.  Would you be able to take along some sort of gain antenna for 6M ?
I've worked guys out of their mobiles at that distance (KF2T in many NV grids) but gain is good :)

Mike, FKO, I'll drop that guy a note - thanks.

I noticed that W3IH in DM63 has been active in the past few days on 6m digital.  I have decoded him on FT8 here in DM65.  Might be worth a try on MSK144? Mike

Hello all - I only need DM63, 73 & 83 for 6M Worked all NM Grids.  All of these should be easily worked on meteor scatter if the NM end is running a small beam and 100W.

need more logs!

Bruce Draper
 

Today is the last day to submit NM QSO Party logs.
**Even if you had only 1 or 2 QSOs, your log is important!**

Need help getting it in the right format? Just let me know. You can send me just the QSO info and I'll take it from there.

New Mexico QSO Party -- Logs due this Saturday

Brian Mileshosky
 

Greetings —

This is a friendly reminder, for those of you who participated in the recent 2019 New Mexico QSO Party, that logs are due (received by email if electronic, or postmarked if hard-copy) by this Saturday — April 27.  

All participants are encouraged to submit their log, regardless of how few or many contacts you enjoyed making during the QSO Party.  Submitting your log allows us to recognize you for your participation and helps us better understand the level of participation in this year’s event.

If you are a member in good standing of a New Mexico amateur radio club, and would like your participation to also help it earn one of the special award plaques reserved only for New Mexico amateur radio clubs, don’t forget to specify your organization's name in your electronic or paper log.

For assistance and details related to submitting your logs, or to verify that your log has been received safe and sound, please visit the New Mexico QSO Party website at www.newmexicoqsoparty.org.

Thanks for participating in the 2019 New Mexico QSO Party!

Re: New Digital Contest Mode: FT4

Mike WB2FKO
 

Quite an interesting development!

The whitepaper shows that Gaussian Frequency Shift Keying dramatically reduces the modulation bandwidth compared to FSK. This is essential to allow multiple stations to occupy the receiver passband, as is the case with FT8.  The channel bandwidth is about twice that of FT8, but their testing shows up to 50 stations can still reliably use the channel (proposed 50.318 MHz for FT4 on 6m).  It would be interesting to learn how much sensitivity is lost (how many dB?) by using GFSK compared to FSK.  Note that GFSK is an established modulation scheme:


They tested the possibility of running FT4 asynchronously, but it seems this leads to excessive channel congestion.  I suspect the Costas Arrays must still be in there to get the FEC to work.  If so, my hunch is that shorter sequences will make Internet synchronization of computers more demanding (tighter) than FT8.  I will have a look at the source code when it is made available next Monday (29 April).

WSJT-X is an open source project, but it's pretty clear that protocol development was done by private communication among a select few.  Given the large amount of noise on the WSJT mailing lists, I would have done the same for the sake of minimizing needless distraction.

FT8 and FT4 are clearly incompatible, which is why there will be separate frequencies on each band.  Will FT4 be used by 6m operators instead of SSB when the band really opens up, even in non-contest conditions?  Will it displace FT8 just as FT8 displaced JT65?

 ..and the WSJT musical chairs performance moves on.

At least THIS "experimental" mode is going to have a timer in it's alpha release that will force it to stop working right before the June VHF contest...

NM QSO Party report, AA5B

Bruce Draper
 

AA5B @ home, Bernalillo County, low power

CW: 214 QSOs
SSB: 258 QSOs
Multipliers: 63 (states + provinces + DX countries + NM counties)
Score: 86,436

Propagation wasn't good, there were 2 periods of high noise levels from local storms, and participation was poor, but I stuck it out for 10 of the 12 hours. Having a TV right next to the station helped -- I watched the Masters' golf tournament all afternoon, followed by the semi-finals of an Ultimate Frisbee tournament ;-)  A bit of SO2R helped keep the mind active, too.

Congrats to KK6MC and N5SJ on good roves, and the other NMVHF guys who braved the conditions (K5TA, K5WO, and N2IC come to mind, but I'm sure there were others).

Re: weekend

Bruce Draper
 

Seems like several of you were doing a fair amount of listening, but maybe no one was transmitting?
That's not a good way to make QSOs  😀

Back to the contest... Are any of you going to submit a log for the contest? Is there anyone who needs help getting it in the right format?

To All,,
Report from ARIZONA...
I was able to catch Duffy/Jim in two counties early in the contest on 40,, but as day progressed, 40 got to long for me so could not find them .. I was able to work 13 counties between 40 and 80,,
I did try some CQ,s on 6 on .130 and some cq,s on ft8 looking for NM stations,, nothing heard..but did NOT put a lot of effort,,on 6..
Thanks to all that worked me..

No HF here. I monitored 50.130 for most of the day as I did work around the house.  I had a single ssb QSO with NM5WB in Rio Rancho.  He called CQ on that frequency about once per hour without any more contacts as far as I could tell.  In the early evening I asked him what he had managed on 6m.  Besides me, he worked AI5I on 50.125.  I had the beam pointed at Arizona.

Weather for NM QSO PArty

James Duffey
 

Snowing a bit here but not bad and some ice. If weather gets worse as we travel north, I will change my route and go south, so my route may change from what I published. Look at APRS.fi for my location.

I think that the worst of the weather will be gone by the time we get further north, but one never knows. - Duffey

To ALL NMVHF...
I will be on all day Saturday, all bands capable, but will be focusing on 20 and 40 and will have 6 meters on the calling freq SSB...
Hope to work many of you!!! and I WILL be looking for Duffy and the rovers,,,and will give out as may points as I can,,
See you all tomorrow

I'd love to see NMVHFS make an effort to win this contest, and I think
it's very doable. K5TA, K5WO, KK6MC, and I will be active in the
contest and we're willing to submit our logs for the club score, but
the rest of you need to do your part. There are NMVHFS members in more
than a dozen NM counties. You guys need to get on and make some QSOs!
It would be great if you could do it on the HF bands (most of the
activity is on 20 and 40 meters), but making QSOs on 6 meters counts,
too. Keep a log (including time, band, and mode for each QSO), and we
can help you submit an official entry later if you need help. The
exchange for those of us in NM is name and county, and the folks
outside of NM will send name and state (or Canadian province or DX
country). The contest runs from 8 AM till 8 PM in NM.
