For normal operational equipment, Matsqui and Newport Corners were generally identical. There were however some differences in equipment fits due to operational requirements, funding or trials.
RF-131-122 Exciter
The RF131-122 exciter (100 mw output) fed the RF-110 linear which
produced 1000 watts which was then applied to the input of RF-745 which
in turn outputs 10kW.
