Site Name: Eric?
Location: Poste Montagnais Hydro-Québec / Eric
Built: ~1970
Operational: Unknown
Coordinates: 51.98483, -65.6545
Lot/Concession:
Condition: Active (Last info as of 2008)
Current Ownership: Hydro-Québec
Distance from paved road: Unknown, area is unreachable by road
Condition of access road: Unpaved road leads from rail line to tropo site
Site Name: Logan?
Location: Churchill Falls, Québec
Built: ~1970
Operational: Unknown
Coordinates: 53.5879, -64.2012
Lot/Concession:
Condition: Active (Last info as of 2008)
Current Ownership: Hydro-Québec
Distance from paved road: 1 Km from main road, not sure if the 500 is paved at that point.
Condition of access road: 1 Km access road of unknown condition, expected to be passable but gated as the site is active
Overview/Background:
While researching the communications link between Goose Bay and NORAD/SAC facilities further south, I found reference (thanks to Alex Lupták) of a whole world of troposcatter facilities (http://rammstein.dfmk.hu/~s200/tropo/Tropo.kmz). I mistook the currently operational Hydro-Québec troposcatter sites "Eric" and "Logan" to be old Cold War facilities that had been repurposed... now, I don't know that's entirely untrue, since there was a 6 site (5 hop) troposcatter network that joined Québec and Labrador built in the 1950s and potentially decommissioned around the same time as the Logan-Eric link was made... but let's say it was purely coincidental that Eric-Logan used seemingly identical antennas and technology.
With a little help from Google, I found the following from the Utilities Telecom Council of Canada:
Extrapolating from the information in that
correspondance, I believe it stated that the link between Eric and Logan
is a 60 channel analog link. Eric to Logan is just over 200Km,
matching the description, and it's only one hop. They do mention that
there is a two-hop troposcatter link used by Hydro-Québec somewhere, and
I'm not sure where yet.
So why is this important? Why care? Why is this so interesting? Well, troposcatter sites of this design were used along the Mid-Canada line at Site 070, 060, 050, 415 and 410 - which were all shut down in 1967. Other sites, like the troposcatter link that went from Hay River to Lady Franklin Point for DEW Line communications were decommissioned by the military in the 1970s. The White Alice network along the West Coast up to Alaska was decommissioned many years ago as well. Polevault along the East coast? Long gone. To the best of my knowledge Eric and Logan are essentially the same as those other troposcatter facilities, making them living museum pieces (as much as Hydro-Québec might cringe from me calling them that).
Directions:
Regarding getting to Eric;
I'm not really sure there's a GMC Suburban-passable road to Eric from Sept-Isles, so it seems the only way to get there is by train. Not VIA, they don't go that far, it's Tshiuetin Rail Transportation (wikipedia here, web site here) The train from Sept-Isles leaves at 8am Monday and Thursdays, and Eric is half a day's train ride away.
I get the feeling that walking up to a remote critical infrastructure building, in the middle of nowhere, with a fence, would be a bad idea; so I'm going to have to ask around and see if I can find someone with an interest in the history of this site within Hydro Quebec. Also, I'd rather see the inside of the facility than just the outside. Now that would be a trick. Wish me luck.
Logan is right off HWY500, the trans-Labrador Highway

With a little help from Google, I found the following from the Utilities Telecom Council of Canada:
"Hydro-Quebec reported that they intend to continue to operate one troposcatter hop in Labrador, which is above 200 kilometers and operates currently in the 1.7-1.9 Ghz band. While Hydro-Quebec expects to replace this hop within the next five years, it needs to continue to use it for the foreseeable future because it has not found any other equipment in another band that could be used."
