William 0 Report post Posted May 7, 2007 I built three "Lost Model Alarm" units and they are very good. I have tested with different buzzers and sounds are obviously not the same but they are perfect but only with Rx Futaba ( negative shift), when I put them in the Multiplex (positive shift) it keeps sounding like a missing Tx signal. What should I do to ? Something in the circuit or in the program? Thanks to RC-CAM to help me and my friends (that told me about RC-CAM) here in Brazil.

Mr.RC-Cam 126 Report post Posted May 8, 2007 LoMA won't work with some Multiplex systems because of its odd framerate. There is a note about this in the project page (reprinted below): Note: LoMA works with nearly all PPM and PCM receivers. It is NOT compatible with R/C systems that utilize slow servo framerates (like some Multiplex R/C systems use). Quote Share this post Link to post Share on other sites
William 0 Report post Posted May 8, 2007 Now I replaced the Rx for GWS (positive shift). The Tx is the same, Multiplex. The control functions are OK but the Loma is still with problem. I supose that the Tx send the signal in this odd framerate condition that you explained so it is transparent for the Rx but not for the Loma, is that correct? Thanks for the help and explanation.

Mr.RC-Cam 126 Report post Posted May 8, 2007 Have you tried turning off the Tx's unused channels? I have no idea if this would help, but it is worth a try. Quote Share this post Link to post Share on other sites
Mr.RC-Cam 126 Report post Posted May 15, 2007 The hex attached file is a special version that has been adapted to allow slow PPM frame rates. It may solve your problem.lma_v13_mpx.zip Quote Share this post Link to post Share on other sites
