Yes, I read this as well. On the one hand, it makes some sense for
explaining its 'orphan' like status, but OTOH... it seems to be a lot
of radio for such a limited use. The account I read mentioned being
tuned to a single frequency to monitor for gas attack, left on 24/7.

Then again, half of the weight and gear is devoted to a multiple
voltage supply, giving it great field flexibility. The R-174 isn't all
that fancy when you get right down to features. It just seems like a
smaller, single-band unit would easily accomplish the same alarm
purposes.

In today's world, it's a great little receiver for your garage or even
den. I had to drill a hole in my bedroom ceiling when I used it as a
bedside receiver, so the aerial could pass through and into the attic
space.
