[Lowfer] [EXTERNAL]Re: 29.4 kHz TACAMO

[Graham]

I never did have an opportunity to visit any of the Canadian DECCA sites 
but in the early 80's I did work with the Canadian department of Energy 
Mines and Resources (EMR now called  Natural Resources Canada), 
Geological Survey Canada (GSC) on the Polar Continental Shelf Project 
(PCSP). Late in '82 we installed EMR's portable DECCA LAMDA system on 
the Northern and North Western coast of upper Ellesmere Island to be 
used in '83 in concert with Project CESAR (Canadian Expedition to  Study 
the ALPHA Ridge). Portable is the operative word if you consider a half 
dozen 18" rack mount equipment cases, ATU, 150 foot tower, and two 15 KW 
diesel generators portable. Interestingly when we sited the three 
stations DECCA red ended up being a wee bit too far from DECCA MASTER to 
permit a reliable lock. We had to use HP RVFS's (5065A's I think) and 
frequency synthesizers at each site. I seem to recall that Master was 88 
(apprx) KHz, Red was 118 (apprx) and Green was 132. Of course operating 
with a rubidium locked transmitter required a lot less hands on than 
otherwise.

I helped install the three sites in '82 and operated DECCA RED on Ward 
Hunt Island in '83. That may have been the last season EMR's DECCA was 
used. I lost track and moved on to other things. I still have the DECCA 
chart that was made for that chain and as usual, when I go looking for 
it I can't find it but will stumble across it when I am looking for 
something else.

cheers, Graham
