===== HX1 =====

The HX1 is a Radiometrix 2m module which provides 300mW of output. The HX1 is a 5V Narrow-band FM module. The module appears to come in two versions, the HX1-FREQ-3 and the HX1-FREQ-10. This information is based on tests of the HX1-FREQ-3 model. Deviation in the Audio Frequency range does not appear to be very linear. Below is a chart of the relative audio frequency response of the module. More information concerning the testing set up can be found here: [[https://k7nvh.com/wordpress/?p=123]].
