2 Hott radios - bad range

Hi Nejc:
If you bind the MX-20 to one GR-16, and the MX-16 to the second GR-16, then I suspect you will have interference problems as both GR-16's will be trying to transmit telemetry.

I believe it was Holger Buss who advised against doing this. It was discussed on this thread:

That's correct.
Here's what the documentation for the GR-16 says:

2.1.1.Binding“ multiple receivers in one model​

If required, it is also possible to bind multiple receivers to the transmitter for a particular model. The first​

step is to bind each receiver individually using the procedure already described.​

When the system is in use, the receiver which was bound last is the Master receiver. Any telemetry sensors​

installed in the model must be connected to this unit, as only the Master receiver transmits sensor​

data using the downlink channel. The second and all further receivers operate in parallel with the Master​

receiver but in Slave mode, with the downlink channel switched off.'​

NOTE: I made a mistake. It's the last receiver to be bound that is the Master and therefore will transmit the telemetry.
Hope this helps.
Andy.

 

Hi Ozkan: Interesting. So you're saying that the Graupner documentation is incorrect? You will have problems with two receivers bound to the same radio?

Andy.

 

So I read through the string a couple of times and have a basic question that I'm not sure has been asked. Most of the literature discusses binding two receivers to one transmitter.

The other postings, including the one from Holger, discuss two receiver/transmitter setup like Nejc. And the result in those postings seems to be bad telemetry data but may not be a control issue problem.

So here's a possible path forward (at least it makes logical sense).

So if you bind each transmitter with a receiver both would be masters? Perhaps the MX-16, if that is the camera unit could be tricked. Label the GR-16's A and B. A will be working with MX-20 and B will be working on the MX-16.

Start with the MX-16 and Bind Recv B and then Recv A. The MX-16 thinks that Recv A is sending Telemetry.

Now take Recv A and Bind it to the MX-20. This is the one that you would run the Telemetry wire into from the MK stack if you are flying the MK Stack.

Now my warning. I have no idea if this would work and whether the MX-16 will not 'see' the telemetry from Recv A.

To bad that there isn't a way to turn of the telemetry mode in the Graupner receivers.
