Odds are it's a generic power meter.... directional coupler, rectifier,
filter and meter. The fancy part is the directional coupler.

There's a schematic for a very similar design in the older ARRL Handbooks,
or you can look at this:

Odds are the RS one uses the same meter for both strips with a switch,
to save costs.

I can email scanned pages of the entire "manual" (two pages!-) of the
Archer
60-4005 "Space Patrol Walkie Talkie" or I can put them on my website
and let you snarf them yourself. Your call.
