- | ====== Tait TM8200 Series ====== | ||
- | |||
- | The Tait TM8XXX series are “PMR” radios that have become popular with Amateurs due to their excellent performance, | ||
- | |||
- | One thing worth noting is the Graphical Display Heads frequently have faulty LCD displays, leading to vertical blank lines. This can vary in severity and in all but the most severe cases the radio will still be usable. | ||

- | ====== Models ====== | ||
- | |||
- | The TM8200 range consists of several models listed below | ||

- | | TM8250 | 1500 Conventional Channels, Graphical Display Head| | ||
- | | TM8255 | 1500 Conventional Channels, 4 MPT Networks, Graphical Display Head | | ||
- | | TM8252 | 1500 Conventional Channels, 4 MPT Networks, No Display Head (RJ45 Only) | | ||
- | |||
- | They are available in the following frequencies. The radio identification or frequency range can usually be found on a sticker on the base of the radio. Watch out for the C0 "Band 3" models which are outside of the amateur bands. | ||
- | |||
- | | **Identification** | **Frequency (MHz)** | | ||
- | | A4 | 66-88 | | ||
- | | B1 | 136-174 | | ||
- | | C0 | 174-225 | | ||

- | | H7 | 450-520 | | ||
- | | K5 | 762-870 (Tx) 762-776 and 850-870 (Rx) | | ||
- | |||
- | ====== Power Requirements ====== | ||
- | |||
- | The radio will operate on 10.8V to 16V and RF power output is stable down to 12v. | ||
- | |||
- | The table below shows the relationship between RF output and DC power in. Note it may not be entirely accurate, but should be good enough. | ||

- | ===== Pinout ===== | ||
- | |||
- | The 25 watt TM8200s use a Molex Mini-Fit Jr connector. Replacements are available on eBay, or if you wish to make your own the housing is part number 39-01-4040 and the pins are 39-00-0078. | ||
- | |||
- | The pinout is as follows: | ||

- | ===== Cable ===== | ||

- | It was previously understood that the TM8XXX series required inverted 3.3v serial in order to program them, however the " | ||

- | The pinout to program the radio via the RJ45 connector on the front of a TM82XX can be found below: | ||

- | ====== Hints ====== | ||
- | |||
- | * The help menu in the Programming Application is very detailed. Worth looking at. | ||
- | * If the radio doesn' | ||
- | * 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. | ||

- | ===== Control Head Notes ===== | ||
- | |||
- | * A TM8235 control head seems to work fine on a TM8200 body that was previously using a Graphical Display Head. | ||
- | * A TM8100 head seems to work on a TM8200 body. Channel limits aren't enforced, so you can program 11 channels with a 10 channel TM8110 head, but channels greater than 9 will be truncated on the display. | ||
- | * A TM8235 head kind of works on a TM8100 body. The speaker, buttons and display work, but the backlight and the status LEDs don't work. There is also some strange flickering behaviour. It's not clear if this could potentially damage something, so best avoided. | ||
