 The Tait T2000 II 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).

+A VHF T2010 has been tested at 1200b (AX.25) and 2400b (IL2P) and performed well for both Tx and Rx. Deviation is limited in the hardware, so 9600b hasn't been tested yet. However, there is an untested {{ :radios:t201x_ii_9600_baud_conversion.pdf | conversion guide}}.

-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, and it's not clear what functions the options board provides. It's a busy board and no schematic or documentation has been found 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.

That said, the basic pin out required for most use cases has been discovered through trial and error.
-To program the radio you will need to open it up and either unplug S15 temporarily, or disconnect the PCB traces. I disconnected them by using a drill on the vias circled in red (Don't drill too deep, you just need enough to break the track):

+A couple of different issue numbers of this board has been seen, that seem lartgely the same with some minor differences in PCB layout. Iss 3 has been confirmed with the pinout below, and Iss 5 is also believed to be the same based on [[https://gist.github.com/makuk66/8165a0971c99b613ea5524e2aec2e8a4]]. There are a couple of wires soldered on these examples so do check your version if you have it. Has been seen in a T2010-321-F00 and a T2010-321-F93.
+With this board a NinoTNC Signals dip switch setting of 1100 was found to work (I'm not sure if the option board matters specifically for this setting).

-===== Programming =====
-==== Programming Cable ====
+====== Internal Adjustment Controls ======
-You can use the diagram below to create a programming cable for the T2000 series. It assumes you're using a DB9 female connector to attach to the RS232 port on a computer or USB serial adapter. The programming operates at RS232 levels.
+You may not need to mess with these, but you can use internal pots to fine-tune frequency, deviation, CTCSS deviation, and output power (and probably a few other things as well based on the diagram).
+When programming the radio, you can set a channel to high or low power, and the power pot will affect both these settings. This can be useful if you are looking for a specific power output. There is a hole in the metal cover through which you can inset a flat head screwdriver to adjust. It is very sensitive, so only give it a little movement.

+====== Programming ======
+Programming the T2000II series is relatively straightforward. The software is referred to as the "T2000 Conventional Programming Application" and Version 3.00 is tested and working on Windows 11.
+===== Hints =====
+  * The software only works with COM1-4 so you may have to re-assign your serial port in Windows Device Manager.
+  * The help menu in the Programming Application is very detailed. Worth looking at.
+  * If you've got a radio that's already programmed, it's best to start with a fresh configuration rather than reading from the radio and making changes, to avoid buried settings causing problems later down the line. The programming application will start with a fresh factory default config each time its opened.

+===== Packet Configuration =====
+The following information should assist you with programming the radio for use with Packet. If a config section is omitted it doesn't need changing from the defaults.
+==== Specifications ====
+Select the band for the radio your programming. Note this must match the hardware.
+==== Transmitter Setup ====
+Set a suitable Transmit Timer and Lockout Duration to avoid the PTT getting stuck on for long periods.
