SFR /Simplex Frequency Repeater/
In DMR mode, this function can be optionally enabled in 2nd generation Caltta devices. In essence, it functions as a repeater in SFR mode using a single frequency.
In Tier 1, it receives DMR audio and data traffic, and in Tier 2, it can transmit this to the radios in SFR mode at 90ms intervals. Currently, the 2nd generation PH690, PM790 and DMR devices can use this function.
With this feature, we can extend the range of radios without installing a repeater that occupies 2 frequencies. Not only is this cost effective, but it also saves on frequency spectrum by using only one frequency.
Whether you are on a site or in a hilly area, the range of your handheld radios can be extended at the touch of a button without any problems with the range of the SFR repeater radio.
For PH690 products, the SFR license can only be activated for v2 versions.
Other brands may have different SFR settings or operation, so please contact Anico Ltd. technicians for testing before purchase.
