JR Radio help
You will have to buy a JR computer Tx to be able to use the model's JR PCM Rx. There are lots of opportunities: 378, 652, 662, 783, 8103, 10X, and more.
There are two different JR PCM formats. The one you need to use depends on the Rx. The Tx models listed above do both. Older JR radios only supported the Z-PCM mode.
You can always replace the Rx if you want to use another Tx brand.
