  • Frequency Profiles - What they Actually mean.

    When creating a race there is a frequency dropdown. In the US I recommend using IMD 5 if you are not using Raceband or Raceband 8 if you are using raceband.

    IMD 5 (Best 5 channels possible, Indoors really benefits from this)
    5685 E 2
    5760 F 2
    5800 F 4
    5860 F 7
    5905 E 6

    IMD 6 (Best 6 Channels possible)
    5645 E 4
    5685 E 2
    5760 F 2
    5800 F 4
    5860 F 7
    5905 E 6

    IMD 5A (Mainly used for testing)
    5645 E 4
    5685 E 2
    5760 F 2

    5800 F 4
    5860 F 7


    IMD 5B (Mainly used for testing)
    5645 E 4
    5740 F 1
    5820 F 5

    5860 F 7
    5945 E 8

    IMD 6A (Mainly used for testing)
    5645 E 4
    5685 E 2

    5760 F 2
    5800 F 4
    5860 F 7
    5945 E 8

    Old 7 (Not Recommended IMD 5 Better)
    5645 E 4
    5740 F 1
    5800 F 4
    5860 F 7
    5945 E 8

    Would it be possible to change how we designate our VTx and VRx channels? Your dropdown doesn't cover all of the configurations of transmitters and receivers out there. For example, there are 32 channel units that include RaceBand, but you only support 40 channel units with RaceBand. What I'd like to see are checkboxes where you can click on the bands that your transmitter and receiver handle. I'm guessing this would actually be a simplification of your frequency software. This change would also give us the option to create aircraft in our profile that are versions with only RaceBand shown as available, so we could run RaceBand-only events while still using your frequency allocation system.

      This is a great idea, or even better would be to explicit list your supported frequencies with checkboxes or a comma-separated list.

          Maybe I'm doing something wrong, but it looks like there are some close 3rd order IMD frequencies in the above profiles. In IMD5, 5800 and 5905 combine to produce 5695, which is right next to 5685. Similarly 5800 and 5685 combine to produce 5915, right next to 5905. 5A and 5B improve the separation a bit, but still have 3rd order IMD frequencies within 15 MHz of the primary frequencies. How much separation between a primary frequency and 3rd order IMD frequency is required to avoid interference issues?

            Maybe it would add too much complexity but if there were a way to specified a preferred list and an acceptable list that would be cool. My gogs do the standard 8 Fatshark channels but I have an external 40 channel Rx on a tripod and my TVx is 40 channels. Could I do any of 40 channels, yeah. But if I had a choice, I'd rather not be tethered to my tripod.
