50 kHz channel spacing is HW dependent. Units with older version boards are still in production.
50 kHz channel spacing requirement kindly specify in your order.
6.25 kHz channel spacing is not available for RipEX-928.

This is gross data speed in above table. User data speed varies and depends heavily
on the data structure, optimization effectivity, protocol on Radio channel, signal budgets
and many other parameters of the network. Practical tests are recommended.

For output power 10 W it is recommended to use input power above 11 VDC.
RipEX-470, RipEX-928 – max. RF Output power 8 W.
