Default JR SX3 radio CRASH!!!!!

I just bought a JR/propo XS3 radio (with the rare 40mHz frequency band) from e-bay. The first problem that I discovered is that I can't get extra receivers for it for my T-maxx. and now after the 1st use. the radio died. It just stopped working and i have no idea why. I checke the batteries and they put out 11.96 VDC. I probed the power swithc and it works.


CAN ANY ONE HELP ME.

THE SELLER ON EBAY WILL NOT HELP ME AT ALL

Rare 40? Perhaps, to the US. Since it's an overseas version, that is probably why you are having problems finding an RS300 or whatever overseas receiver version that will work. Try Australia.

Two problems I see here... #1) EBAY = BUYER BEWARE! Most folks on ebay are reputable and trustworthy, but service after the sale is almost non-exhistant. Looks like you now own a radio that doesn't work See if JR will service this radio, but I doubt they will because: 2) 40 Mhz is ILLEGAL to use for RC in the United States and it's Territories. The FCC governs all frequency usage, and they say NO![sm=eek.gif]

Your best possible solution is to contact JR to see if they will warranty this radio and repair it to a servicable level, then sell it to someone that is either going to an area that can use it (i.e. Military personnel going overseas), or another RCU member in an area that can.

Sorry to be the bearer of bad news....

I've been thinking about this and it's bugging me. I've been in the market for a new XS3 so I was trolling ebay ... the number of people selling these 40mhz units, and implying that U.S. buyers can use them legally by calling it "rare" is ticking me off. Some may say it's the buyer's responsibility to check these things out, and to an extent that's true. But I have no doubt that these sellers realize that they are selling a product that it's illegal for at least some of their buyers to use, and of course they'll do nothing to disuade them of that delusion.

This is tricky.

People buying a computer radio should know that 40mhz is "illegal" in the US. If not, well, TOUGH!! You are/should be experienced RCers, and if you haven't figured out frequencies by now you probably shouldn't be buying a computer radio!!

"Illegal"??? Well, technically, 40mhz probably is, but in the real world, I really don't think the FCC is gonna send out a triangulation truck team to hunt you down (unless maybe you're next to a military base or Washington DC). It'd be nice to know what the 40mhz sapectrum is currently being used for here in the states. I'm guessing it is NOT reserved for anything critical like police/fire/defense, but that's just a guess.

But as for your radio DYING, well, I dunno what to tell you. I'm sure the e-bay seller in HONG KONG (I believe) made no promises re. a "warranty", and that's a risk you had to know going into the deal. That's why I limit my e-bay purchases to things that are relatively simple, like RC parts, toys, clothes, etc. (a rotary hammer is the only "machine" I got).

Will Horizon/JR back you up?? Dunno, but sending it to someone overseas & having them send it to JR MIGHT work, as mfgs usually fix stuff without receipts, as they know thu the serial #s when it was made & they then have a good idea as to when it was sold, too. WAITAMINUTE....MAYBE you can call Hobbico & make up a story saying you just moved back to the US after a stint in Asia....and see what they say. But I'm guessing they know about the hong kong e-bay seller & might not be cooperative.

Sorry for your hassles, but at least you are serving as a lesson to all of us (no that that means squat to YOU!!!).

Dean,

There are several users of 40 Mhz in the states... Illinois State Police is an example... Most of your D.O.T.'s are using 40, as well as just about any other Gov't agency that travels far from their "base" radio's. The "Lo-Band" (40 Mhz) is quite active here in the St. Louis area!
DOD uses several radios in this band as well... Go to a large Military installation and fire up a scanner sometime... you'll get 40 Mhz, 220 Mhz, 300 Mhz, and more!!

No, they more than likely won't send a triangulation team out, but that isn't all that neccessary... most states have agencies that handle this on a local level.

You're out of luck. It was a bad decision, there will be no warranty from JR, there isn't a track in the US that will allow that radio because of insurance. It's not legal to sell the radio in the U.S. I'm thinking.

I would tell you that the seller you bought it from is not a very good seller either, if it's the one I'm seeing in a listing search over there. This guy's had some real 'funny' auctions over the last few months.

i have bought one of those radios and had to send it back i think you will find it isn't 40mhz but is actual 75mhz with 40mhz lables i think it will be ch 69-75 or something they are 75mhz check the back of the maual. if you look around also i think you will find it is a fake the buttons are different and it isn't possible to change channels. this is what i discovered with myne i sent myne back and got a refund so before you do anything check the display and see what ch it is displaying then check the maual. i think you will find it is actually 75mhz. I sent myne back because in australia 75mhz is illegal.

Send it to JR and they will reconfigure and tune the radio to a legal fequency for you to use, the best for you to get is the ham bands 50MHZ, but that can be subject to interfearence. The second choice is pcm or ppm, they are dual conversion with signal encoding that will look for your exact signal within the channel your running, and it will reject all other signals on that channel number. It acts like aircraft bands, high or low band and it raelly filters out a lot of garbage to give you the best signal possible.
