VTX Frequencies

So I've been a spectator at a few events and people always seem to be calling out VTX frequencies.  "Anyone on 3?".  I've seen charts of numbers and bands and I've seen the numbers on Fatsharks and wasn't actually sure what all this crap was.  You have 40 channel transmitters, 48 channel transmitters, and 48 channel receivers etc. Only 8 can really be used at once otherwise people get washed out.

The FatSharks I've seen have shown the band and frequency, as well as a 4 digit number.

When I was racing my RC Car, I had a list of Pinion and Spur gear sizes taped to the lid of my case, so I could quickly work out gear ratios in between races without getting my calculator out.  I figured I'd print out this list so I don't have to remember this crap.  This is the one I created if anyone is interested.

So there are 5 bands, which are numbered 1 to 5, or A, b, E, F, r.  That's handy isn't it.  There are then 8 channels, numbered 1 to 8.

My goggles, the Eachine VR D2 (no not the new Pro version) uses numbers.  These are displayed on the front of the goggles in clear view of everyone except the wearer.  They use 2 x Seven Segment Displays (digital clock numbers) to show the Channel and Frequency (in that order).

With my new VTX I can select the band and channel (and output power) so if I'm told we're using band F and I'm channel 1 I know that it is 5740. or 14 on my goggles.  Channel 1 and Band 4 which is F depending on which numbering scheme is being used.  The numbering is the same on my VTX.

This grid will come in handy so I know what people are talking about.
