How to obtain Broadcasting rates
There are basically 3 different types of systems and 2 ways to obtain broadcasting rates, timing, GV and answers to your questions. Depending on your work and outcome you are looking to get one system which might work better for you.
Here a quick overview:
Probably the most used and known one is the Hieronymus type, for which Galen Hieronymus obtained an US patent, number 2,482,773. There are several versions of this type of radionics instruments available which include but not limited to Kelly, Rogers, SE 5 and Mattoid instruments. All these instruments work with a stick plate to obtain rates and the capacity to scan, send, potentise, balance and reverse rates.
Malcom Rae instruments uses cards with sector marks and a potentiometer dial for homeopathic potencies. The plates can be used to transfer physical patterns to the witness as well. These rates are obtained by pendulum dowsing (no stick plate). Some of the newer versions of Malcom Rae are compatible and can be linked with Kelly instruments.
Projection wheel and the Sri Sanjevini cards are used if you do not have an instrument on hand. Pendulum dowsing is also used to find the appropriate patterns in projection time.
