May 06, Yeah, forgot to state that I’m looking to be using 27mhz for the build.
If you must use discrete components, look up some old Heathkit radio control circuits. Thank you for your quick replies! Even using the IC, it should provide plenty to do. Looking for 3 channel circuit diagram.

I’m assuming this forum is the right place to ask these kinds of questions, but datawheet it isn’t I apologize. Even though it makes my job much easier, I would also prefer to be making the whole circuit without using an IC that does everything for me: Here is the companion data sheet for the LM transmitter chip.

These devices are well suited for use at 27, 49 or 72 mhz. I found a few circuits, but I am a bit unsure about the usage dtaasheet these ICs.

Pin 6 appears to be used to determine the number of transmitted channels in a prospective system. May 04, Posting Quick Reply – Daasheet Wait. Any micro-controller having 3 analog inputs and 3 digital outputs can do the job. Some of those may have operated at 27mhz. So, there is not real schematics, but only programming examples.
I’ve been searching for many hours and have yet to come upon any feasible circuits. The chip does a lot, but you still need to provide support circuitry to complete a project. Something like thisand shop? Thanks for informing me about the IC, I’ll definitely be using it for my project. Welcome to the forum. If anyone could point me to any electronic schematics or any useful information in general, I would be extremely appreciative.

Looking for 3 channel circuit diagram Hey everyone, I’m looking to build a simple RX and TX with encoder and decoder from scratch for an upcoming RC plane project. Originally Posted by Magranon.

The Arduino boards can also do that. Does it even matter what value they are?
