Diefenbunker / CEGHQ & REGHQ, Transmitter, and Receiver, Sites

2015.08.20 Update:
After an excellent presentation by Ralph Cameron (VE3BBM) tonight at the former site of CFS Carp, now The Diefenbunker Museum, in the cafeteria, about Cold War communications infrastructure, I figured I should dust off this blog post and move it to the front of the line again.

It's not a revelation to anyone that CFS Carp (Now known as The Diefenbunker Museum) was not the only continuity of government facility in Canada; they were built across Canada for the local politicians and their civil servants to hide in, in case of nuclear annihilation.  Each of the Regional Headquarters sites also had a separate communication bunker, usually a couple of stories down, like a "Diefenbunker", but a lot smaller.  These TX and RX sites would have been built and maintained by the military to ensure communications were kept going after the world had gone to hell in a hand-basket. Antenna farms were on site with the mini-bunker, and there was a separate unmanned receiver site with another antenna farm.

This is where my research gets fuzzy.

If each Diefenbunker had a TX and and RX site, where exactly were they?  I can find some information, but not every site has coordinates associated with it, or is it easy to find.  Many of these facilities have been decommissioned and bulldozed.

Here is the map, to the best that I know, of where these sites would be.  I'd really like to get better pictures of the sites and what condition they are in now.  Are there still fences?  Any sign of the bunker or antenna farm? Is there nothing buy cows?  Inquiring minds would like to know...

Canadian Department of National Defence Antenna Sites

While trawling MERX, these locations came up; with some Google Satellite View snooping it was pretty easy to identify their locations.  However, I'm light on details as to what system they support.  Are they part of the "Strategic National Communications infrastructure"(citation)?  I would guess that Cardiff and Riverbend are remotely operated by CFB Edmonton, and that Carrying Place and Point Petre are operated by CFB Trenton; but that's only a guess, based solely on proximity. Three of the four sites have the unmistakable LPH-89 antennas in their antenna farms, so I assume some of their duties involve HF communication.

The next time I'm near Trenton I'll certainly check out Carrying Place and Point Petre and hopefully get some better pictures of their antennas.
