Attention: RC-CAM.com will be closing down August 2021.

The RC-Cam.com forum was the very first online community dedicated to the advancement of wireless video cameras on radio controlled (R/C) models. This is now called "FPV" (First Person View). We are proud of the contributions that our members have made to the FPV hobby.

We've seen significant changes over the last twenty years. Initially there were a lot of eager R/C hobbyist that built their own video systems. Allowing these creative individuals to share their work was the purpose of this site. Now the FPV market is flooded with low cost systems; Sadly DiY FPV video projects are now rarely discussed.

RC-CAM.com (main site and forum) will be closing down August 2021. This is being announced now (March 2021) so that everyone has time to download any information that is important to them. After the site is shutdown the information will no longer be available here.

We appreciate every member's involvement with advancing the FPV hobby. It is indeed sad to say goodbye to all our online friends. Be safe and stay healthy.

  1. Which receivers did you use for your 4-way diversity? Cheers, Reuben
  2. Hi Terry - I like the tracking antenna. What receiver module did you use? Cheers, Reuben
  3. With a TX but without an RX aerial I can get to about 200m. It does have the SMA mounded though. Good to hear the black lines are not normal. I am sure the PCB I am making will fix that issue. By the way, the channel pins on the devices - I had assumed that no connection to these gives channel 4 as a default? Do they need to be grounded if not in use? Do you simply pull one high and the others low to use that channel? This isnt too clear in my datasheet. Cheers, Reuben
  4. So, I had a quick play with the video system. I need a bigger field. I found that with a normal antenna (no gain) on the TX and a normal antenna on the RX, the link was fine over the distance of the field (about 100m). No surprise there then. The slightly surprising thing was that the reception was pretty much the same without a RX aerial at all (just the SMA). There was a fair amount of glitching (black lines occasionally flitting up the screen) instead of very steady video. Any suggestions as to the cause? Or is this just normal. Also any comments on the no RX aerial findings? Ch
  5. Got the basic system working tonight. Nothing special, just the normal antennas. Its good to know it works though. Range tests tomorrow. One question: testing it around the house I get various types of interference. I wanted to check what wifi interference 'looked' like? I reckon that is the kind which shows up as white bands which flit down the screen at regular intervals? As I go near my wireless router, this kind of interference gets worse... Terry, I will be very interested to know how your 1.394GHz tests go. I need to get some PCBs made up to test this stuff better, and rule
  6. I have purchased a few AMW630Tx/634RX modules and a wide variety of aerials (from no gain to 14dBi gain, both omni and patch). I will be spending some time in the local fields....
  7. Ok, I have paid my money, and made my choice. I will let you know how I get on. Cheers for the help and suggestions, Reuben
  8. Thanks Terry, I'll take a look at them. Did you consider 5.8GHz? Is that legal in the UK? I suppose that it wont go as far though as its a higher frequency...
  9. I have struggled to find suppliers for the 1.394GHz systems - any suggestions? Although, I do think that the 2.4G are probably still the best way to go just because of the better selection available and the price. What online companies do people use to buy the 2.4G systems and especially the aerials? Cheers, Reuben
  10. Thanks - yes it seems difficult to get hold of the certifications. Another problem with the 1.394GHz systems are that there is no sound channel (if you need sound that is!). Am I right in thinking this? Also, I was going to ask, if I get an 8dB patch antenna that a lot of people seem to be using here, I assume that is pretty directional? How directional is it? What sort of angle? And finally, what would be the best Airwave pair to buy for 10mW? Which of their receivers have people have best success with (in terms of sensitivity)? Cheers, Reuben
  11. Good point about the TX antenna. Having looked into the 1.394GHz systems, I think this seems like a better idea now. However, I am struggling to find more offerings than the link I sent. Can I ask where you have bought your system from? I would prefer a module that I can include in my own system really, rather than something that is already boxed up. Are you sure the 1.394GHz 500mW systems are legal in the UK and license exempt? Cheers, Reuben
  12. Thanks Terry, Is 10mW also the limit for 900MHz systems? It seems that there may be pros and cons for a 900MHz system: pros: potential for greater range (due to fundamentals) and possibly the 900MHz band is less crowded cons: far less offerings in the 900MHz band; The cons probably pretty much cancel the pros... Also is there a 1.394GHz band which is license free in the UK? I have read that the power can be 500mW without a license in that band in the UK: http://www.radcon.com/pdfs/cct1394.pdf The same company also make a 10mW 2.4G system which is quoted as up to 500m and
  13. Hi, I have been enjoying reading through a lot of the posts on this forum. I live in the UK and would like to buy a video transmitter/receiver pair which will give me a really good range (1K or more). I am aware that there are some regulations about the transmitter power that is allowed over here in the UK, although I have read conflicting values of 10mW and 100mW... Do the 2.4G solutions out there (e.g. the 633 from airwave) have the potential for ~1k range, keeping legal in the UK? Also, what would be the best type of receiver antenna for maximum gain, as i guess there are no regul
