Re: Battery segregation
- In most Radio-Relay repeater buildings the radio bays, support bays, rectifiers, and batteries were all in a common equipment room. Battery stands were located near the front door; repeater bays were located against the back wall near the tower. There was usually a small exhaust fan in the wall near the battery stands, on the engine-room side of the building...
Some fairly accurate TD-3 repeater-building floor plans may be seen here:
The 56'10" x 56'10" TD-2/TH repeater building became standard construction in the early sixties:
It consisted of nine 18'6" bays with 16" support columns: (18'6" x 3) + 16" = 56'10". The engine room occupied one bay in the back right-hand corner, the HVAC room occupied the bay immediately in front of that; leaving a 2 x 3 bay area center and left, plus one bay to the right for equipment - about 2,350 square feet. TD-2 radio and support occupied the two left-hand bays toward the back; TH radio occupied two center bays also near the back. The three bays along the front of the building contained the 12V 24V and 130V batteries. An exhaust fan was mounted in the right-hand wall of the right-front bay. The building entrance door was centered on the center bay, so the first thing you walked past when you entered the building was two rows of battery stand line-ups on either side of you...
