-The Tait T2000 series are an older generation of "PMR" radios that have become popular with Amateurs due to their availability, reasonable pricing and models available for the 70cms, 2m and 4m bands (Note they're single band only). +relocated to [[radios:tait2xxx]]

-====== Disassembly ====== +
- +
-Due to the plethora of available options boards it's wise to partially disassemble the radio to examine the hardware prior to attaching any external devices like TNCs. +
- +
-===== Required Tools ===== +
- +
-You will need a: +
- +
-  * **Torx T20** - for the screws on the base of the radio +
-  * **Torx T10** - for the internal screws that secure the logic and options board. +
- +
-You might need a: +
- +
-  * **5mm socket, 3/16 socket, needle nose pliers, or small adjustable spanner** - to remove the DBXX connector screwlocks +
-  * **Tait Release Key / Small flat blade screwdriver** - to remove the mounting bracket +
- +
-===== Removing the mounting bracket ===== +
- +
-Some of the radios will come with a mounting bracket. In theory these require a security key to remove the radio body from the bracket. In practise, some are loose and just slip out, with the brack sliding over the //back// of the radio. +
- +
-If yours is more stubborn you will need to insert the security key or similarly shaped object into the hole in the left hand side of the control head near the volume control, which will release a tab and allow you to remove the radio body from the bracket. +
- +
-If you don't have a key or similar object, and don't mind some minor scratches to the bracket you can prise the two metal shells apart and remove them that way. Insert a thin flat blade screwdriver or similar implement in the gap between the two metal shells, and ease them over the plastic bumps (Marked with red dots in the image below) one at a time. Repeat for both sides, top and bottom. +

-====== Reassembly ====== +
- +
-Reassembly is the opposite of disassembly +
- +
-====== Options Boards ====== +
- +
-The T2000s expose options connections internally which made them popular for interfacing with data systems like those previously found in Taxis. It's not always possible to tell externally which board has been fitted, and various boards exist - some of which are undocumented. +
- +
-===== TS02491 ===== +
- +
-These were found in a pair of radios purchased from a radio rally. There was no indication on the outside of the radio these boards had been fitted. The boards appear to operate as data modems, possibly 9600 baud GMSK. Note this isn't compatible with G3RUH's 9600 baud specification. +
- +
-It's a busy board and no schematic or documentation has been found at present, and the presence of the TCXO circuitry usually found on a separate module makes it difficult to just remove the options board without somehow providing the missing TCXO function. +
- +
-Almost all the pins on the 15 pin DE-15 connector are connected to the rest of the circuit with small SMD resistors, so some scope exists to remove them and insert "bodge wires" to bridge out the rest of the circuit but this is so far untested. +

- +
-====== Power ====== +
- +
-The radios require 13.8v DC, and drain around 300mA at idle. +
- +
-In a pinch, 2.8mm spade connectors fit firmly over the pins in the connector. There's a slight risk you might damage them, but if its a £5 radio from a rally you might not be too concerned. The spade connectors fit firmly and probably won't be pulled out by accident. +
