Inteface, Sanwa RD-8000 and HF - How to switch off HF in Sanwa RC ?

[Gobol]

HI!

I'm new on the forum. I have a Sanwa RD-8000 and I've created USB-FMS interface, I've googled all the Net but I haven't found how to switch off the HF module of this TX.
Is there such possibility like in Hitec's TX-es - short-circuiting two pins in interface cable socket ?

Thanks in advance.

Just take out the crystal.

Is it safe to HF amplifier ?

1. We always do it here. But I can't make any promises.
2. I happen to have the RD8000 manual. On p12 you will see the Trainer System chapter that says: "The frequency of the Trainer transmitter is unimportant ... NOT turned on..." - what I gather from this is that if you feed the Tx from the trainer socket without switching on the Tx, you actually turn it on and you bypass the HF system.
