If it’s correct, you’re hjmark the comp to rails. I would suggest you to add a 10K pull-up resistor between Vcc and RA. At least it’s work. Maybe Joe has bifocals like me.

Join Date Mar Posts I just add 10k pull up resistor at Rx data pin and 10uF at Vcc.

Same thing for your PICs. Join Date Aug Location Look, behind you.

Actually I want to send a character using my RF module. What PIC are you using? Maybe the following link will help you a little bit http: Use the one for your frequency and even with out a good ground plane you should see improvement. So anyone here have any ideas about the antenna?? I didn’t read the according datasheet to see if it affect anything though.


The rx3130a uses a comparator as I explain at http: Seems to be the one you’re using right? Join Date Sep Location montreal, canada Posts 6, The time now is I have tested a SAW controlled transmitter and superregenerative receiver from the same company. Gold is the money of kings, silver is the money of gentlemen, barter is the money of peasants – but debt is the money of slaves.

problem with sending data using RF module

TE pin should be tied low too unless the oscillator won’t run. You should have a decent distance between the transmitter and receiver Hi, try a direct connection porta to porta with following.

Adding another comparator might be useful for educational purposes but is of little practical value IMO. Members who have read this thread: I don’t know how to troubleshoot the problem because I’m new to this thing.


Once the wire connection will work, i may suspect 2 other things.

So I use this simple datashest to test it but my LCD at the receiver board display nothing. Page 1 of 2 1 2 Last Jump to page: The uf cap is a bit much. For your Information, I put 1M resistor between these 2 pins.

The data can use almost any protocol desired, including RS with or without manchester coding. Adding another will not help.

But It’s fine to me.
