I got this TX and a couple mr200 rxs were just working fine a couple days ago was trying to bind them agian because they would not work. I put bind plug in did the procedure like I normally do it binded ok but when I removed bind plug and hooked battery to RX and nothing. any ideas out there? will a faulty speed control mess up a RX ?

That TX is not designed for use with the MR200 or MR3000 RXs (DSM-Marine).

It requires a DSM2 or DSMR RX, like the new SR210, SR310, SR410, etc.

How old is the TX and when it the last time you updated it??

[Darin Jordan]

Here is what I can tell you about these radio systems:

1) The TX and RX generally need to be the same generation of protocol: DSM2, DSMR, DSM-Marine, etc. In this case, the TX is NOT DSM-Marine Compatible.

2) The EARLY runs of the DX4S and DX4R were released with support for the DSM-Marine RXs. In a later update, and later releases, this was removed.

3) IF you had an early TX that was compatible, and you did a Spektrum Raceware update from www.spektrumrc.com, then the update will have removed the DSM-Marine support.

4) RX Binding and connection after it's bound can be affected by weak RX batteries or low BEC voltage.

5) RX Connection can be affected by having the TX too close to the RX. If you move the TX away and make sure the antennas has Line-of-sight with each other, it will generally bind or connect.

Hope something in 1-5 helps. :)

Great info here Darin, it is a few years old and I haven't changed anything thanks very much for your help, geno

#5. I learned that the hard way some years ago. Later when fellow club members couldn't bind their transmitters, I told them to take two steps back. Worked every time. Don't know if that is the OP's problem, but it is worth a try.

What kind of receiver are you using? Did that same receiver work with your previous transmitter? Fresh batteries? We need more information to help you.

And what is it in? If any sort of CF hull and the antenna is not clear of the hull you won't have any range.

Thanks for asking. It's a mean machine 2, a tp 4070 , a sf 300 lite on 6s. Two freshly charged 3s . No carbon fiber the ant. is approx. 2 inch exposed. 5.7 volts at the radio. Four brand new freshly charged aa's.

[fweasel]

receiver? Is that new or used? Was it previously paired with your last radio?

[Beaux]

Both of these are brand new out of the box. I have a sf310 in my pirate same issue.

Does the receiver antenna have a ~1" section of clear coating at the end of the antenna, which is otherwise solid gray?
