Angry Terrible Reception!

I have a Novak Xxtra and I was racing today, and couldn't even get a lap in because my reception is very bad. I didn't cut the antenna. Just ran it like normal.

First, I tested to check how far I lose reception. With the TX antenna all the way down, the car would go only 2 feet and then losing reception. Then, TX antenna all the way up, about 12 feet till loss of reception.

I cleaned out the receiver before the race to get rid of any dirt that might be in it. Took off the case, blew the dust/dirt out. Then mounted the receiver on like normal.

Anyone know why the reception is so bad? There are no scars on the antenna. Doesn't have anything to do with the other electronics.

Stay away from Novak recievers!
Altough i love the esc's and chargers (I do own 3 esc' and 2 chargers) from Novak, their recievers are JUNK! I've had bad experiences with the Mercury, Xxl and the older version (can't remember the name). They can't say its because of the electronics i use, since i use only Novak esc's.
I've learned that the best thing to do is to use only recievers made by the manufacturer of the transmitter.

My 2 cents

That's odd, because I've had a XXL for awhile now, & it's worked just as well as my original recievers(all KO's KR-297 FM ones). But that could have as much to do with how good KO's radios are(I know of some folks who've tested a bnch of transmitters & recievers with an oscilloscope, & found that the KO's were always closer to dead on the frequencies they were supposed to be running on than any of the other brands), & the XXTra uses the same internals as the XXL, only adding the sunthysized frequencies. Now, something I would look into, though, is to try your radio again with its original factory reciever, & see if that makes a difference. If it still glitches like you're seeing, then the problem could be the transmitter(I've had that happen to me before, a few solder connections on a board in my TX has gone bad, & it had that same effect on my reception, but some easy resoldering by the factory techs fixed it right up. I could've even done it myself, if I'd had a guide to disassembling it so I could take it apart & reassemble without risking breakage)....

Well, I had the receiver in my TC3 rally before switching it back over to the Pro 4. And I was using a different TX also. I noticed the same thing. Bad reception. I'm probably going to take apart the receiver tonight to see what's wrong.

Found out the problem. Took apart the receiver again today, and saw that the antenna got cut .

BTW, I was running the Futaba 3PJS w/ Spectra and Hitec Lynx FM.

I have XXtra. The only problems I've had were problems on certain frequencies on certain tracks, dialing in another frequency, like going form 61 to 71 solved that problem.

Thumbs up xxtra

I have an xxtra in all of my cars and have never had a problem. I bet once you fix that antenna it should work awesome.

I've used this receiver ever since it came out. And it's just awesome.
