To make FrSky work with a 9X Tx the options are as follows:
Steps required to make a stock 9x Tx work with FrSky DJT (plug-in) Tx Module
1. Unplug the T9X Tx module from the rear of the case
2. Open up the Tx module caes (4 screws)
3. Either snip/cut or un-solder the antenna wire that runs into the body of the Tx
4. Open up the Tx body and remove the antenna from the body - you must do this step to avoid antenna interference from the plug in modules new antenna
5. Close up Tx body
6. Plug in DJT module and attach antenna
7. Set dip switches according to the Rx type you're using, bind to Rx, fly.
Steps required to make a stock 9x Tx work with FrSky DHT (DIY) Tx module
1. Unplug the T9X Tx module from the rear of the case
2. Open up the Tx module caes (4 screws)
3. Either snip/cut or un-solder the antenna wire that runs into the body of the Tx
4. Remove the boards that are in the Tx module - you wont need these again unless you decide to change back
5. Rescrew the lid on the now empty Tx module and plug it back into the Tx body
6. Open up the Tx body & install the DHT module as per Bruce/Paul's videos on YouTube - typically 3 holes to be drilled for 3-way mode selection switch, ops state LED & bind button. You get to decide where you want to place these. 3 wires to be soldered onto the Tx PCB.
6a. Keith has shown an alternative approach to installing the DHT inside the Tx body above - this approach still requires the routing of the wires for the 3-way mode select switch, LED and bind button to the inside of the Tx case and the routing of the antenna wire so its a little bit more involved that having the DHT on the inside, but it is a very tidy solution.
7. Make sure all installed wires from the DHT don't inhibit the movement of the gimbals
8. Close up the case
9. set 3-way mode swithc according to the Rx type you're using, bind to Rx, fly.
I've done both (to different Txs) and persoanlly prefer the cleaner apperance of using the DHT module. But i can't discern any performance difference between the two.
