What's the difference between the USA and International versions of the Immersion RC Tramp HV?
International VS US verions of Tramp VTX? |
26-Apr-2017, 09:41 PM What's the difference between the USA and International versions of the Immersion RC Tramp HV? 26-Apr-2017, 09:43 PM First of all, it's the power restrictions. ie. in most countries we can only transmit 25mw max. Secondly, frequency - for example 5945 is only available in Europe but the vtx IS THE SAME you just turn on Eu version in the menu. With the magic wand you can also go 48chn. On the tramp (I guess it's illegal in us?) and most other countries... (think you have to scan first an se if others at using the freq before you use... check your country rules before you get shot by a trigger happy drone 27-Apr-2017, 03:08 AM Now Im not sure about the tramp but most commonly the difference is NTSC or PAL video systems. NTSC is usually used in US 27-Apr-2017, 08:38 AM (27-Apr-2017, 03:08 AM)Drone0fPrey Wrote: Now Im not sure about the tramp but most commonly the difference is NTSC or PAL video systems. NTSC is usually used in US Nah, the video transmitter couldn't care less whether you feed it one or the other TV standard. For FPV, the best standard to use is NTSC, regardless of where you are in the world. Although NTSC is a slightly lower resolution than PAL, it has a frame rate of 30 fps instead of PAL's 25 fps and the higher the frame rate the better when it comes to fast movement. 27-Apr-2017, 02:44 PM (27-Apr-2017, 08:38 AM)unseen Wrote: Nah, the video transmitter couldn't care less whether you feed it one or the other TV standard. I thought certain transmitters only put out one or the other (still new to fpv and learning so this helps my own clarity too. Pun intended ) and depending on what your reciever uses, they needed to match. When I first started I thought my goggles were crap for a second until I realised I needed to check both were using the same video format. 27-Apr-2017, 03:54 PM I've never heard of a transmitter that cares one way or the other about the signal format. The signal format is set by the camera and the only things that need to understand what format the signal is are the OSD and the display device that is connected to the receiver. For actual transmission, all the transmitter does is frequency modulate the carrier signal with the video signal. The receiver then recovers that signal from the carrier. Neither of those processes require any knowledge about the actual content of the signal on either the transmitter or the receiver's part. If there's an audio signal to send as well, the transmitter just drops that into a separate pair of channels at 6Mhz and 6.5MHz above the video carrier, regardless of the video signal format. 27-Apr-2017, 04:23 PM (27-Apr-2017, 03:54 PM)unseen Wrote: I've never heard of a transmitter that cares one way or the other about the signal format. Thank you for the clarification. Makes sense now. 31-May-2017, 05:48 AM The international version can go through the entire 40 channel spectrum. Some channels are now banned in the US. The US version will not allow you to wand it into certain frequencies. I know the first E channel and the last 2 E channels are now illegal. |
