Re: DM63

Would it help the meteor scatter possibilities if it was done from T or C, 70 miles farther from W9RM ?

I must confess that I have been remiss in uploading my rover sites to I will try to do that in the new year. Here is a site that I have operated from in DM63.  It is a pullout in Hwy1 south of Socorro, just before HWY crosses over I25. It is about as close to the northern border of DM63 as you can easily get to from Albuquerque. There is plenty of space to set up there and there wasn’t much traffic or many lookie loos when I was there. It was quiet as there are no power lines, that I remember anyway.  It is about 320 miles to W9RM from there.
I ran a Radio Mobile path calculation and the predicted SNR is about -1dB. That is probably optimistic in NM and winter. None the less it indicates it is a workable path. You might be able to make it on CW. In comparison, the water tower at TorC site has a calculated SNR of +1 dB.  The McDonalds parking lot calculated SNR is -20dB.  The limiting terrain is at W9RM’s end. These SNRs are probably high by 5 to 10dB.
FT8 should work better at those distances than meteor scatter.  With meteor scatter and no antenna elevation, one end or the other may be better off pointing 180 degrees off the direct path and working meteors off the back.
I hope this helps. -Duffey KK6MC

The website shows, under the "reference" pulldown some good operating spots for rovers and portable operators. Scott, Steve and Jim identified 3 good operating spots.  I would ask each of you to capture this info in the format shown on the website for future operators. We made good use of this info, as it was, during the 2017 contest year when the Central States VHF Conference was held in Albuquerque.  There were many operators who decided to stay in the area and operate the August contest using info from the website.  We got some good feedback about documented operating spots and how easy it was for someone unfamiliar with the area to plan and execute their contesting activities.

So, that's why we have that info available and I would like to encourage everyone with "tribal knowledge" to contribute to that info published on our website.

When complete, just forward that info to Mike WB2FKO for upload to the website.

Thanks a bunch,

Jim, that's good info for future VHF contesting and should be stored
somewhere - the same with K5TA's and N2IC's descriptions..  On the NMVHF
web site, there are descriptions of hot spots in many different grids.  It
would be pretty neat if more people could use the format already presented
there and write up grid spots they are familiar with.

In this particular instance, pretty much any reasonable location will work
for meteor scatter.  Actually, at this close distance (DM63 to DM58),
elevating antennas up to 5-10 degrees above the horizon would enhance the
path, although I can't do this at my end on 6.  However, Rovers should
keep this in mind.  The display screen of WSJT & WSJT-X, which is the
program must everybody uses when running M/S now-a-days, actually has an
elevation number displayed, which is simply calculated on the distance
between you and who you're trying to work.

Ideally you'd want to go up to Magdalena Ridge. At 10,000 ft this is
not a particularly good time to try that though, I can see the snow up
there from town now. AA5PR ran from up there as a rover last June with
WSJT. The DM63 line is just south of Socorro, the line runs just about
through the landfill. If you take the old Hwy 1 south from Socorro,
once you pass the landfill there are a couple of pullouts where one
could set up. A bit farther south, without crossing I-25 on Hwy 1 but
continuing south,you can access some open country, mostly BLM land
with pretty good shots to the north and east. There's an old AT&T
tower down there and the road turns west and rises into the foothills.
Plenty of open space to operate.

West from here we do have the two ridges but I have been able to work
AZ and southern CA with my 3 el and 100 wts pretty regularly.

I was going to send you eMail in the next couple of days. I'm finally
back in NM and can do it soon. We have company this week, but next
week is open. I have 3 elements, 500 Watts.

Would anyone be willing to take a trip to DM63 with equipment to run
meteor scatter (or brute force troposcatter if you can run power)
with me ?  For M/S, 100W and a 3 element beam would probably do the
trick - more is better, of course...

That's the only grid I've never worked in NM on 6.  Maybe during the
January VHF test in a couple weeks or the weekend after New Years for
the peak of the Quadrantids ??  With decent equipment on your end, it
should be an easy shot and I'm sure there would be other interested
