I have an old 4ch Hobbico TX with no output plug. Is there anything I can buy so I can connect the TX to my computer?

I thought I heard somewhere that there is a cable where you can screw into where your atenna goes?

Am I crazy?

What you need is the PPM signal before modulation. Anybody with a scope can find a point inside your transmitter where you can pickup this signal and bring it out.

I don't know if the system you describe exists, however getting the signal directly within the TX is much simpler.

Since you can usually find a TX that someone thinks is no good for flying any more with the plug for about $10 to $20... I'd just go checking around for one instead of messing around nside a TX trying to do the conversion.

While the conversion can wrk... there's no point risking frying your computer with a small soldering error.

Ha, great idea.

IMHO, if you know what youa re doing, there is no risk. Anyway, often there is a connector on the PCB that allows you the grab the signal without soldering.
