Frequency variants and Ordering information

The TX1 transmitter is manufactured in the following variants as standard:

For AUS applications on 151.300MHz:
TX1-151.300-10     Transmitter
RX1-151.300-10     Receiver

For NZ general applications on 173.250MHz: 
TX1-173.250-10     Transmitter
RX1-173.250-10     Receiver

Other variants can be supplied to individual customer requirements at frequencies from 120MHz to 180MHz and/or epitomized for specific data speeds and formats. However these are subject to minimum order quantity (MOQ) and long lead time. Please consult the Sales Department for further information. 

Some of the non-standard frequencies readily available. i.e. no MOQ or long lead time, are as follows:

Part number: TX1-xxx.xxx-10 and RX1-xxx.xxx-10 (where xxx.xxx is the operating frequency)

Notes:  1.  Complies with the ETSI standards but NOT approved 
2.  For specialised application, NOT for general purpose 
e.g: 121.500MHz is an international distress frequency 
3.  NOT an European Harmonised frequency. Consult local radio requlatory authority.
