Nice write up Keith.  You're getting things churned up in western CO.  All good work.

I tracked Duffey and worked pretty much 50 through 1296 at every grid.

I worked several in AZ:
WA7XX, N7IR, K7KMR, N1RWY, K1IEB, KA7CVJ, N7DPX and N7GP/r (formerly WA8ZWG) on 2 meters
N1RWY N7GP/r on 222
N7GP/r on 432 (50ish watts here)

Also got the three guys in El Paso on 144 and 222: K5PHF, WA5FBM and K5LA and Floyd K5LA on 432 as well.

We tried hard to put 1296 in the log but were unsuccessful.  They copied me 559  but I could not complete a copy for a contact..... always missing some tiny bit: one grid square character (even though I know damn well what it is) or a rr.  I spent a lot of time on 1296 working long period QSB and didn't get much for my new 600 watts except Duffey in grids where we had worked before on 1296 with 10 watts.  Need a preamp of more antenna on that band.  I spent a lot of time with the AZ guys on 1296 as well with no results. Mostly hearing nothing except CW rock pings. When I started on 1296 I couldn't hear a damn thing then took a look and found I had put 28 dB of transmit attenuation on the receive side as well.  It was much better once I "redesigned" the station but not good enough.  Tough band for long Qs with moderate conditions.

Several guys were on the air locally that have not worked a contest in years. Newby W0AMT/r (QRP) did a nice job hitting high el op spots on foot with an FT-817 and a Ukranian 222 transverter. 50-432.  I'll turn him on to SG Labs for 902, 1296 and 2304; great for hikers.

Thx for DM58 Keith.

Meteors were pretty poor after about 1300Z Sunday, although, a few hours earlier, they seemed to start well.  I was able to call CQ on 50.260, running split-mode and work a slow, steady stream of callers for about 45 minutes.  2M rocks didn't produce well, but I didn't really go at them aggressively or get too pushy on PingJockey, since I was mostly 'playing contester' instead of contesting.

Being September, there were no sporadic E openings on 6 that I noticed and even the be-all-end-all miracle mode of FT8 didn't produce any long-haul stuff.  Funny - I can recall working several stations in the 900-1100 miles range on ionoscatter using SSB or CW almost every contest.  One would think FT8 would be even better at that but there was seldom 'anybody home' on 50.313.  Hard to figure out what's really going on in the minds of the majority of FT8 mode users.  Also, meteor pings just play holy havoc with FT8 decodes - not as miracle as some make it out to be, 'eh ?.  My 6M go-to mode of choice for years in these conditions was always CW (you remember that mode, right ?)  I don't think that would get you too far now, unfortunately.

2M tropospheric conditions (if you can call them that in this part of the world) were average.  The rovers with decent antennas who got far enough east of the front-range foothills were easily workable.  Those that stayed close to I-25 ?  Not so easy.  I was able to work into DM89 and DN81 with good signals - both rover and fixed station.  The DM/DN-70's were not so easy.  Sunday mornings 2M "tropo" conditions were above average, with WE7L in over S9.  Unfortunately, there was hardly anybody else around.  Thanks to K0UK, who got on as promised, for the DM59 mult on 6 & 2, another hard to get one.

Rover station KK6MC once again showed how it's done.  I was able to work Duffy with relative ease on 2M from 5 of his 7 New Mexico grid stops and even a few on 6.  These Qs were 250-300 miles across a 14,000' mountain range 50 miles south of my QTH.  All but one QSO was on CW (you remember that mode, right ?)  Some 2M attempts were met with very bad QSB, but just sticking with it for a few minutes and waiting out the fade cycle, usually brought the signal back up to Q5 from in the noise.  This is a good point to remember if you're new to VHF or attempting a higher frequency band like 432 for the first time.  Stick with it - deep cyclic QSB is normal and what goes into the noise usually comes right back out again, although on 432, the cycle MAY take a few minutes (or longer).  This is not a western phenomenon - back in W9-land, it was very common for a long-haul attempt (400+ miles) on 432 to take 15-20 minutes and ultimately end up with Q5 signals both ways.  Whether the time spent is worth it or not in a contest situation is up to you, although the rules now allow even single op's to transmit on multiple bands at the same time.  That's something to think about when planning station architecture.

A new local showed up on 2M from about 3 miles south of me and proceeded to call CQ a bunch on 144.200, sometimes on top of the few front-range guys who were workable.  I worked him, thanked him for being on from my home grid, which is usually impossible to work and then we had a frank discussion on the why's and when's of 2M from the west slope.  Somebody gave him a 2M all-mode radio and antenna, then a few days before the contest, he caught one of those 'big' mornings into the front-range and worked WE7L at over S9 - then, he worked a guy up on Grand Mesa with a big signal (line-of-sight, of course).  So, armed with that 'knowledge', he was all ready to tear up the state on 2M SSB !  Hopefully, in the future, he will be more 'ear' then 'mouth', seeing he's down in the bottom of a canyon with 25W and a short beam fixed east.  Not much, but enough to be 40-over in MY receiver.  I guess I'm spoiled from having the valley pretty much to myself for the last 7-8 years :)

I worked George, AB0YM/R several times, including answering his FT8 CQ from DM89 on 6M for a new mult.  I again caution those who sign 'slash-R' with FT8.  What you think the program is sending might not be what actually goes over the air - I'll leave it at that as it will probably get fixed with the release of WSJT-X Ver 2.  George, if you read this, be advised you were S9 at the start of the contest on 2M, calling CQ in my face for 5 minutes when I was calling you.  I'm running considerably more power then you in your rover.  All I can figure is you were in motion and must have had a very high noise floor, either from the urban crud or from your own vehicle.  It Was VERY Frustrating :)

The biggest news is that the trash covering the entire 6M band, emanating from a local FM broadcast station, has been cleared up after a lot of tough work.  Many thanks to the responsible parties !

Re: Sept VHF

James Duffey
 

Keith - Thanks for the kind words. 

Although I made 7 stops, I only visited 6 different grids, so we only missed in one,. I visited DM64 at its extreme ends diagonally, DM64xx near Moriarty, and DM64bw in the Malpais National Monument. That turned out to be a good strategy as I worked several AZ stations easily from the west end of the grid that there was no way to work from the east end. I may do more of that in the future. There was  lot of activity in AZ and the trip through the three western NM grids paid off. 

I was really surprised to hear you come back to my SSB CQ on 2M in DM74.  That was a nice QSO and one that I will remember for a long time. 

I echo your comments on troposcatter QSB. The amplitude of the QSB is pretty well defined at about 15dB peak to trough. The time period varies a lot, with time constants from fractions of seconds to minutes and even hours. So the rule of thumb is that if you hear someone and it is not a ping, chances are their signal will increase and you can work them if you put in the time, are patient and follow some kind of routine like taking turns transmitting on the first and second 30 seconds of a minute. As you know, we have worked a lot of QSOs this way, some in excess of 300 miles if I recall correctly. I have a modest set up in the rover; 100W to a 8ft Yagi up about 11 feet. 

W0AMT/r was also out in NM and gave out a lot of QSOs. Although QRP he had a good signal when I worked him and gave out a lot of grids. He also hiked to the top of Mt Sedgwick and had a commanding signal from there. Things have changed since I first started roving in NM and was the only NM rover for several years. 

My first rove stop ever was DM55 near Prewitt in 2007. I think WB2FKO was the first QSO I made as a rover. So, it is always nice to work Mike from DM55. It reminds me of my origins. For many years my rover was the only VHF contest station in DM55. W7QQ/has since activated it, and now N5SJ is active with a well equipped 2M station. N5SJ and I were joined by W0AMT/r this contest for three active stations in DM55.  Who would have thought?

There were lots of AZ stations on, and I know that they were worked by many in NM up to Santa Fe or maybe beyond? For many years I have been trying to work AZ from western NM to no avail, but I think it was always an activity issue on the AZ end as I worked lots of AZ stations from the western NM grids this year, as did N5SJ. I also heard the AZ stations working W7QQ, N5SJ, and others. 

I rate the September contest this year high. Part of that was my laid back rove plans and allowing enough time on Sunday to try long haul QSOs to AZ.

It is always nice to hear people’s contest experiences. It helps all of us be better. 

Not sure if either of these groups allow attachments, but as have attached a picture of the rover in DM55 with Mount Taylor in the background.

ARRL SEPT VHF

Jonesy W3DHJ
 

Saturday was grim. Sunday was probably grimmer.
My ONLY front range ("regional") QSOs were with
Ken, W0ETT, Duncan, WE7L, and George, AB0YM/r.
Those three folks made up 84% of my total contest QSOs.
Thank you fellas, for I would've given up and quit FAR sooner than I did.
Special thanks to Duncan, WE7L -- who spent a little time over the
weekend, trying to boost my spirits now-and-then.
My only other Colorado contest QSO was with Keith, W9RM.
Then there was Larry, N0LL.
THAT WAS IT!!!!!!!!!!!

I had "hopes" during the Broncos halftime - nothing.
I waited until a half hour after the Broncos game and gave up.
I monitored 2M during the 1 hour drive back home - zilch.
I should've quit at 2PM at my last QSO.
But for AB0YM/r, it was a waste of time to haul the 432mcs equipment
and put up the antenna at each stop.

I give up.
I've decided this is/was my last ARRL SEP VHF.
If most of the region's VHF operators think the ARRL SEP VHF
is not worth showing up for, who am I to buck the trend.

It's simply not worth the wear and tear on the equipment, the vehicle,
and me to spend Friday for vehicle setup, Monday for teardown, and waste
Saturday and Sunday listening to receiver static while swatting flies.

RR Jon,

I'll track you as best I can.  I'll listen on 50.125 and 144.200 both USB.  We will set up 222.100 USB contacts from the 144 contact.  Will use CW as required by signal strength.  You may reach me at 505.205.4253 (voice and text) Good Luck to you and have fun!

I will start the contest in Los Lunas in DM64.  I will probably be set up in the El Cerro de Los Lunas trail head parking lot. If I can get my act together in time I will hike to the top and activate the  El Cerro de Los Lunas SOTA summit W5N/SL-015 

I have family commitments from 3:00pm to 7:00pm. I will be on from my backyard in DM65 after 7:00.

I will return home to DM65tc. I can stop in DM64 on the way home if anyone still needs that.

You can reach me at (505) 228-5491 . Text is best as I have a record of who calls when if I get busy.

I will have 6M to 1296 exclusive. On Sunday I have allocated some extra time to work the guys in AZ. It should be possible from DM64 and DM55, but DM54 is only a mediocre site and I doubt it will hold up.

Enjoy the contest! - Duffey KK6MC/r

Jim, I'll track you on APRS and try to work you on 2M from your stops.  If 2 is good, we can QSY to CW on 6M  - maybe 50.098 +/-.  I don't have antennas up for any other bands right now.

Do you have 10 and 24 GHz with you?

Sorry for the late notice, but I have been traveling a lot, just got back from a 4,000 + mile road trip and was not sure I was up to roving this weekend. I decided to, and with a limited route, so here is my itinerary.

I will start at the Moriarty convergence.

Saturday September
Time on         Grid                    Time Out
1800Z           DM75ba          1900Z
1915Z           DM74bx          2015Z
2030Z           DM64xx          2130Z
2200Z           DM65uc          2330Z

I will overnight at home, perhaps operating from the driveway if conditions warrant or if anyone wants a QSO.

Sunday  September
1400Z           DM54xq          1530Z
1615Z           DM64bw  1745Z
1915Z           DM55xh          2045Z

I will return home to DM65tc. I can stop in DM64 on the way home if anyone still needs that.

You can reach me at (505) 228-5491 . Text is best as I have a record of who calls when if I get busy.

I will have 6M to 1296 exclusive. On Sunday I have allocated some extra time to work the guys in AZ. It should be possible from DM64 and DM55, but DM54 is only a mediocre site and I doubt it will hold up.

Enjoy the contest! - Duffey KK6MC/r

W0AMT/R September VHF Contest Plans

Jonathan Fox - W0AMT
 

I will have 6, 2, and 432 via an FT-817 and 222 via a Ukrainian transverter. I will be barefoot on all bands except 222 where I will have about 20 watts via a RFC amp on loan from Duffey.

I will start the contest in Los Lunas in DM64.  I will probably be set up in the El Cerro de Los Lunas trail head parking lot. If I can get my act together in time I will hike to the top and activate the  El Cerro de Los Lunas SOTA summit W5N/SL-015 

I have family commitments from 3:00pm to 7:00pm. I will be on from my backyard in DM65 after 7:00.

I plan to activate Mt. Sedgwick W5N/C0-001 in DM55 on Sunday morning. Depending on the success of that my stretch goal is the Cerro Rendija W5N/CO-013 summit in DM54.

I finished the 222 transverter kit this past week and did some initial setup. Per the article on the NMVHF website by W7QQ and KK6MC I checked the gate bias and found it at 2.5 volts. I adjusted it up to 3.1. I did not have an opportunity to get an on-air report of the IMD improvement.

This past Wednesday I was able to make contact with NK5W on 222.110. However, I had some frequency stability issues. At first I was low by 2 MHz, after transmitting a few times I found I was  5 Mhz high. After ending the qso I went back to the assembly instructions and found that I had missed a detail. There are two mounting holes on the transverter board in addition to the mounting hole for the MOSFET. The instructions say to only use the #1 hole as using the #2 hole can cause oscillations. I missed that the first time. I am still using the #2 hole. I insulated the PC board from the metal mounting screw with a nylon washer.

I am hoping this change will improve my frequency stability issues. If not I will remove it completely and see what that does.

The WA5VJB 4 element cheap yagi I built for an antenna worked great for the QSO I had.

Is anyone available for a 222 qso this weekend? I would like to do another on-air check of the transverter.

Hi Jon,

1:00 PM today sounds fine unless the lightning kicks up again from this weather system.  I'll look for you on 222.150.  Nice to see that you're on 222. It's a great band.

2018 TAPR Digital Communications Conference -- Sep 14-16, Albuquerque

Brian Mileshosky
 

Greetings — 

For the first time in its 37 year history, the ARRL/TAPR Digital Communications Conference (DCC) comes to New Mexico, and will occur September 14-16 at the Sheraton Albuquerque Airport hotel.  DCC is an annual national conference, attended by hams across the United States and beyond, that highlights digital communications technologies, techniques, and capabilities currently being utilized within amateur radio or under development.  This event is the largest amateur radio digital communications conference in the nation, and attracts some of the most innovative hams from across the United States, Canada and beyond.

The weekend will be filled with introductory, semi-technical, and technical presentations, meals with speakers, technical demonstrations, prizes, and opportunities to establish or build relationships with some of amateur radio’s notable technical innovators. All amateur radio operators, from beginner to experienced, would gain from the practical information and demonstrations that will be offered at DCC.

Topics that are typically highlighted at TAPR Digital Communications Conferences as well as within the conference’s 100 page printed proceedings book: 

— Software Defined Radio (SDR)
— Digital voice (D-Star, DMR, P25, WinDRM, FDMDV, DRMDV, G4GUO, etc.)
— Digital satellite communications
— Global positioning system applications
— Precise Timing
— Automatic Packet Reporting System (APRS)
— Short messaging (a mode of APRS)
— Digital Signal Processing (DSP)
— HF digital modes
— Internet interoperability with Amateur Radio networks
— Spread spectrum applications
— IEEE 802.11 and other Part 15 license-exempt systems adaptable for Amateur Radio
— Using TCP/IP networking over Amateur Radio
— Mesh and peer to peer wireless networking
— Emergency and Homeland Defense backup digital communications in Amateur Radio
— Updates on AX.25 and other wireless networking protocols
— Other topics that advance the Amateur Radio art

The TAPR Digital Communications Conference also serves as the annual meeting of TAPR. Rocky Mountain Ham Radio, New Mexico has partnered with TAPR to serve as this year’s local event host.

Complete details about this year’s Conference, including the schedule of events, the presentation lineup, conference hotel information, and much more, can be found at https://www.tapr.org/dcc.html  Online registration is available at https://www.tapr.org/dccregistration.php   A flyer has also been attached to this email.

PRESENTERS WANTED: There are a few remaining speaker slots at this year’s DCC.  The kinds of presentations you saw (or gave) at the New Mexico TechFest would be perfect for the DCC audience.  If you are interested in presenting on an emerging or relevant amateur radio technical topics, technique, experiment, or project that you have been working on, please email both myself as well as Steven Bible N7HPR (steven.bible@...) with your thoughts.

Whether you attend for just a day or for the full weekend conference, we hope you’ll take part in this unique amateur radio event, meet some of amateur radio's technical innovators from across the United States and beyond, and gain from the practical information and demonstrations offered by the TAPR Digital Communications Conference.  The Conference continues its rotation to another part of the country next year, so don’t pass up a great opportunity to attend while it’s (finally) in our backyard!

Thanks and 73,
Brian N5ZGT
