[HamWAN PSDR] Rattlesnake Mtn HamWan cell site

[Carl Leon]

I do not know WA State requirement for tower work. I do know that one of the
towers up there is new (last year or two) and is PSERN. That is 100%
contractor handled. One of them may be the old King County tower, which I
think is going away (everything moved to PSERN tower). It has been too many
years since I've been at that site, so am not familiar with what is there
now. Sorry.

Thanks for the reply, Carl.  EO_ says it's DNR (not KC), so that would be WA
state; do you know what their requirements are for climbing their tower?
(hopefully their don't require a vendor that needs to be paid)

Stephen,

 

As to the accuracy of the coordinates, it is likely they were referenced to
NAD27 and Google Earth uses WGS84. That can easily account for the couple of
hundred foot discrepancy you note.

 

As to tower climbing, volunteer or professional, they must have proper
certification. King County pretty much limits climbing to a specific vendor
they deal with.

In follow up to the Kiwi chat conversation with @EO_...

 

Attached are a couple photos related to two of the 7 communications site
towers adjacent to each other on Rattlesnake.  Four of those are clustered
together in a small spot: PSE, King County, USFS, and possibly DNR.  These
photos were taken in July 2019, and the USFS site appears abandoned in that
cluster.  One of these photos shows the towers for King County and what is
possibly DNR, but I don't recall exactly which one is which, perhaps you can
ID (my impression is that KC is the taller of the two).  The taller of these
two happened to have a sign on its shack with lat/lon coordinates on it,
which is shown in the second photo.  Interestingly, those coords places a
Google maps marker at the edge of the forest clearing a couple hundred feet
away from the entire cluster, perhaps because the coords are not precise
enough.  Both of these towers have a clear view of North Bend and Snoqualmie
Ridge IMO, although as EO_ pointed out the HamWan link from Haystack or
wherever may need to be at the very top.

 

I will be exploring the possibility of getting volunteer certified tower
climbing help for a workparty proposal to you this coming spring/summer when
the road there is passable.

 

On a separate note, King County supposedly also owns the tower site at I-90
exit 38 Tinkham Road that should be LOS to their Rattlesnake site, and may
be a possible hop towards getting over Snoqualmie Pass and eventually
eastern WA in the future?  Given their involvement in WA EMD and Cascadia
prep, perhaps they would be amenable.  There is a tower on top of nearby
Grouse Ridge (next to the Fire Training Academy, and an old now unused site
on Mount Washington that could be investigated as hop sites, both accessible
by roads in summer.  Just a thought.
