The HPI RS4 comes with a AM reciever and i have a JR XR3I. Can I just put a JR FM Crystal in the stock reciever and it work. Thanx
 
No, you need a JR FM 75 Mhz compatible receiver, ie JR, Airtronics, Hitec DCX, Novak XXL or XXTra.

AM and FM won't work together, however, it has nothing to do with frequency....AM means "amplitude modulation"...the command sent from the radio is based on varying signal strengths....FM means "frequency modulation"...the radio commands are sent on a changing wavelength....in any case, the equipment won't work together...you can change frequencies within the same band, as long as they're the same type (AM or FM)...27mHz or 75mHz won't intermix either...hope this clears things up.
 
Russ Winn,
Great explanation. We appreciate posts that help people learn and understand. It takes an extra few minutes to give an explanation but I like to think its all about quality not quantity.

Keep up the good work.

I think i understand but yet I dont. Say could i take a 82 channel 75mhz FM remote and operate a 82 channel 75mhz AM reciever
 
It wont work.
They are two different animals.
Because they operate differently it may even harm your radio is in-fact you could even get the crystal to fit.
 
Think about it this way. You can listen to the radio station 104 fm on your radio because you have tuned your radio to that frequency. The station is transmiting frequency 104Mhz and your are listening to it because who have tuned your radio to recieve frequency 104Mhz. You can listen to any station as long as you match the frequency that the radio station is broadcasting. Same thing for AM radio stations. You have to switch to AM in order to listen to AM. You can't listen to FM on AM and AM on FM. The frequencies dont match.

Hope this helps
 
Yo dog did you notice the date on this LOL but none the less great job using the search 12-29-2003, 12:05 PM
 
Goes to show that there are people looking for info and willing to share info no matter what the post date. It's ok, it can help someone asking that same question this year too.
 
Yes that was another great way to explain it. For someone that didn't understand it when Russ Winn did , this recent one by Rod Dog30 was just as effective. Good Job Rod Dog30!
