Message-ID: <1252373925.3419.18.camel@usuario> Hello, I have a question, I have read some of the comments about use multiple transmitters to increase the distance range. I tried to connect two transmitters in parallel but when I have connected the Tx signal both of them turned off. I have read the particular comment made it at september 23th 2007: On Sun, Sep 23, 2007 at 03:52:30PM +0200, Jakub Sykora wrote: > This is called Ronja dual head and the range is increasing about 40%.

CL But I want to know specifically if the Resistor 1(R1=82 Ohms) of anyone of the Rx has to be removed if I want to this works. Thank you for your answer.

You don't remove the resistor on RX but on the TX that is not at the end of the cable.

I do not understand when you say "on the TX > that is not at the end of the cable." You have a cable from the Twister which is normally leading into a single TX Make a tap say 50cm from the TX and connect addidional TX directly to that tap. Remove the resistor from the additional TX. Karel > > I understand that I have to connect Tx signal and Ground signal which > come from the Twister on both Tx that I want to connect in parallel.

There's a trap. If the resistor you are looking at has it's value specified as 2M2 then yes, 2.2 meg-ohms. > El mar, 29-09-2009 a las 14:57 +1300, Mark Robinson escribi?: >> Cecilia Puon wrote: >> > Hello, I hope some of you can help me .
