Ashtech SP has released a great little radio solution for the ProMark series of receivers.
The 410-470 MHz SATELLINE-EASy 1 Watt transceiver is compatible with Pacific Crest EOTT and Trimtalk protocols at 9600 and 4800 baud; 12.5 and 25 KHz bandwidth. The radio is powered from the GPS Receiver’s internal battery (both base and rover) and connects directly to the bottom of the receiver with a single cable.
The radio costs $2,255 with an antenna and includes the power-data cable, a very nice mounting bracket w/ pole clamp and an extension for mounting the antenna above the GNSS antenna.
The EASy is fully configurable from the front panel; you can change the frequency directly. You do not need a PC to configure any of the radio settings.
Best of all, the radio has five LED’s that show link status and the LCD display that shows the link signal strength and cycles through all of the radio configuration settings.
I tested the receive range and it is better than the PDL RXO radios in the ProMark 500’s and about the same as the new ADL radios.
These radios also make great little 1-watt repeaters with a simple power cable.
I really like this solution and recommend it without reservations.
