WR Communications Manuals

Someone on the repeater-builder mailing list mentioned that they were looking to get rid of a bunch of manuals for old radio equipment by WR Communications, Ltd., a defunct two-way radio company from Canada. (See their Industry Canada listing here.)

For some reason, despite having not previously heard of the company, I couldn’t bear to see a bunch of documentation get thrown away, so I arranged to have them shipped to me. I’m planning on scanning all of them in and OCR’ing them. Even with a fast scanner with a document feeder, it’s going to take a bit.

I’m currently in possession of the following manuals. The last number is seemingly a document number they used for some purpose.
