Radios

There are a number of radio modules in use with descriptions :

Module Price Stability Complexity Frequency Further Information
Radiometrix NTX2 Low Poor Simple 434.075 or 434.650 Data/Linking to an Arduino Suitable for RTTY
Radiometrix LMT2 High Excellent Simple 433.900 → 434.650 Data/Linking to an Arduino Suitable for RTTY
Radiometrix TX3H ? Poor ? 869.50Mhz Data/Linking to an Arduino Suitable for RTTY
Radiometrix HX1 Medium Good Moderate APRS 144.800/143.900/144.390 Data/Linking to an Arduino Suitable for APRS
HopeRF RFM22B Low Poor Moderate 413.000 → 453.000 Data/Linking to an Arduino Suitable for RTTY

Note “Poor” stability means unless well insulated the frequency will drift noticeably.
