ow die had in frankrijk tijdens een iets te harde landing wat scheuren in de frameplaten opgelopen......nooit gezien en daarna nog bij pont du gard gevlogen, geflipt gerold enzzz.... niets gemerkt, zag het nu pas bij het zand, maar alles blijft nog wel zitten, maar zal op de scheuren wat secondelijm doen, dan kan ie er weer tegen.....
FAQ Immersionrc poor range zei:In most cases this comes down to either an antenna problem, or a strong interfering source on the plane. In rare cases it can indicate a defective EzUHF Tx or Rx. The first step to troubleshooting this is to eliminate the antennas as the problem source.
Antennas:
Some antenna problems are caused by incompatibilities between 'SMA', and 'RP-SMA' connectors. Even though these look identical to the untrained eye, the 'sex' of the center pin is different between the two standards. If an RP-SMA antenna is screwed onto the EzUHF's SMA connector, there is no connection between the center pins, and the antenna is useless.
Another antenna problem can occur if 433MHz (70cm Ham band) antennas are used with the 'UK' spec firmware, which operates on 459MHz.
Power Level Mis-configuration
Another potential range issue occurs when the EzUHF Tx settings are set to control the output power level from a R/C channel, but that channel is not setup correctly (or the operator forgot that the Tx was programmed to do this, and tried to use the external switch instead). This can cause the EzUHF Tx to stay in low-power mode, even though the switch is in the high-power position. Either correct the R/C channel setup, or change the settings in the EzUHF Tx using the ImmersionRC Tools.
Interfering Source:
This is fairly common. A device on the mode radiates broadband noise on the band used by the EzUHF Tx. The GoPro Hero is a very common source of this, as is the older FatShark HD camera.
To identify this kind of problem, the built-in (unique) Spectrum Analyzer, in the EzUHF Rx, may be used. As an example of how to configure this, read this thread.
If an interfering source is shown to be the problem, the frequency band used by the EzUHF up-link may be changed. The ImmersionRC Tools may be used to do this. Ensure that both the Tx, and Rx, are changed, and remember to re-bind the Tx and Rx after changing bands.
Defective Equipment:
In the case where all other debugging techniques show no problems, the EzUHF equipment should be returned to your retailer for testing, and possible repair or replacement.
Helping us to help you:
As a last resort, please post a video, with full telemetry stream in the audio channel, on the FPVLab ImmersionRC forum. One of the ImmersionRC team will diagnose the data stored in that telemetry stream, and hopefully be able to give a clue as to what the problem is. Note that this requires the cable link between the EzUHF and the EzOSD.
