Where does the JHB Special Rules east begin from the north?Is Cullinan in the Pretoria FTA2,or in the JHB Special Rules east area?
I used to change Frequency from Pta FTA to Jhb SRE only when I crossed the Witbank highway.

Just north of Cullinan dam and just south of Jag airfield. Most guys change frequency on the northern shore of Cullinan dam

Nicow...you'd be nearly 10 miles inside it already if you change over the highway...

Splinter is 100% correct.

Use the Cullinan Dam as reference...Refilwe is a township (Shacks) on the North Eastern shores of the dam... change over to 125.40 as you get there approaching from Potties side...Unfortunately the boundary is a curve in that area, difficult to know exactly where it is without a moving map.

Once inside the SRE area remain at 7000 southbound...or (6500 and below)...whichever you can comply with.
Northbound traffic should be at 7500ft or (6500ft and below).

Thanks Splinter & Bundy
