Sepura Frequency Bands

Band Coverage  NOTES TG  400 - 433 MHz Good for use on amateur radio 70cm band  TL 368.5 - 400 MHz   Avoid  TN 380 - 414 MHz   Avoid  TR 350 - 372 MHz   Avoid UO 440 - 473 MHz Covers PMR446 band and commercial band  XB 851 - 870 MHz   Avoid  TZ 410 - 430 MHz Most common found on second hand market. Could be used on 430MHz but would "bleed" out of band. TS 370 - 400 MHz   Avoid  TW 380 - 430 MHz Also common on second hand market. Could be used on 430MHz but would "bleed" out of band. TT 380 - 400 MHz Pretty much only used on the Airwave network in the UK. Avoid like the plague! UW  407 - 473  The holy grail of coverage. Covers the entire amateur and commercial bands, and even includes PMR446.

HW (Hardware) code The hardware code contains some useful information if you want to find out more about a specific terminal. The two main areas of concern are the frequency coverage and the encryption that the device supports. On handhelds. remove the battery and you should find a sticker with the Hardware Code. On mobiles, the sticker will be located on the main unit. The HW code will look like this on an SRH3800 on TW band: PSGTW001T400100 Ignore the first three characters, and look at the next two to get the "band". Refer to the chart on the left to find out what frequencies the device covers. The 6th digit tells you about the encryption. 0 = Clear (No encryption). 1 = TEA1 2 = TEA2 (Probably a missing Airwave set. AVOID!) 3 = TEA3 On Sepura devices, there are a few hidden menus. Key in the following numbers: *477 Network Quality, Neighbour Cells, GPS Information, Hard/Software revision and more. *2797 Battery information page. *762 Start streaming GPS data over the serial connector.
