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 was announced several months ago (March 2021) to allow our members ample 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. I was hoping to see the answer to this question... Will the D480A SAW filter increaese performance in this receiver. I looked at the Data sheets, and the origional SAW filter shows a 21 DB insertion loss, while the D480A is around 19.5 dB. Is this worth doing ? Mike
  2. I have replaced the saw filters as recommended on my 900 MHZ, and 1.2 GHZ video equipment with the D480A filters with good results. When I look inside my 2.4 GHZ video receivers, I see the same poorly performing type of SAW filters that the other equipment has. Is there any performance gain to be had by replacing the SAW filters in 2.4 GHZ receivers ??? Thanks, Mike
  3. I really liked those group of videos, especailly the one where you ask you friend " What are you doing " just before the wings come off your plane ! I am still trying to push the limits, which is why I am here after a long absence trying to improve my video range Mike
  4. I have not tried one, but guess I could build one into the circuit. This is something I may try in the future, so the question of the day is, will amplifying, then attenuating the signal increase prformance ? And how much attenuation should I put in ? Mike
  5. Hi RC Cam, I remember some years back watching some really neat videos of you flying your FPV plane to some impressive altitudes and ranges. I see a lot of your technical posts which are always helpful, but I am wondering, do you fly anymore ? Mike
  6. Hi RC Cam, I have tried two different types of LNA amplifiers on my 900 MHZ video receivers, both times with very poor results. Both attempts were very good LNA's from reputable companies with very good specs. The latest was this one for 900 MHZ http://www.minicircuits.com/pdfs/TAMP-960LN+.pdf My results were more noise in the picture, and slightly less reception of a weak video signal. I am using the standard 900 MHZ video receivers with upgraded saw filters ( no cheap chinese stuff ). Any idea why I would be getting such poor results whenever I put an LNA in the antenna line of my receivers ? Thanks, Mike
  7. Daniel recently tested a couple racewood 500 mW 900 MHZ video transmitters, and found that both only put out about 125 mW. It seems that these 900 MHZ video transmitters just do not put out the amount anywhere near of power that is promised. Mike
  8. Do you think an LNA in addition to the saw filter modification would increase the performance of this 900 MHZ video receiver ? Mike
  9. I got the AVT-8710 Time base corrector to fix my " Blue Screen " problem and it works GREAT The time base corrector keeps the video from tearing when the signal starts to get bad, and when the signal is finally lost, generates a color bar pattern instantly keeping a monitor from going into " Blue Screen Mode " and prevents recorders from shutting off. The beautiful thing is, the AVT-8710 is designed to fix really bad video, so it will not go to the color bar mode until the video signal is totally gone ! In other words, it will not take away any video that you could fly by, and it helps video that is trying to tear itself. Its a bit expensive at 210 dollars, but well worth the price for uses. Now I can use any modern video equipment or recorder I chose without fear of shutting down !!! Problem solved Mike
  10. Everyone, Thanks so much for all the advice and answers to this question, now I have just one more question, what is the meaning of life ??? Hahah, OK, it seems that terry has the closest thing to a solution that I can find, which is a Time Base Corrector. The one in your Link Terry looks like an exact copy of the AVT-8710 , which is what I just bought. Your test video looked pretty good, the point at which it went to color bars being generated was reasonable, with almost no usable video anyways. It appears that this would keep my Monitor happy, but only one way to find out. I will let everyone know what my results are when it gets here and I get it hooked up Mike
  11. What about a slightly different approach to this problem then. There has to be a chip that is sensing the video, and switching it off and replacing it with blue when it does not see video. If I knew which chip did this, I could just jump the video directly to its output so that it would never switch off. I read a post on RC Groups where a guy fed video directly to his TV by bypassing the tuner and feeding video directly to its output in the LCD screen. Anyone have any idea what this cursed chip would look like, or how to find it in the TV ? Terry, The Time Base Corrector is something I am still looking at. How did yours behave, what results did you get with it ? I am not looking to record right now, I have that covered, but I do need something that would work for my monitors, so it does not have to be as perfect as it would for your recorder. On the TV, if the signal breaks up, it will come back... PS RC Cam, My guess is that the LCD monitors would just look for video sync pulses, I cant immagine that they would get super complicated about colors etc when its so easy just to cut the video when the pulses are lost, and start it again when valid video sync pulses are there. Just a guess, but its much easier, work good ( for them ), and is cheaper that way. Mike
  12. Kilrah, Even the most expensive monitors have the " Blue Screen of Death ". I have a very nice, expensive car screen that I want to use because of its exceptional brightness in the sun, so I need to solve this... My sharp 37 inch flat panel monitr is the same way, not cheap and not something I want to change out over this issue. This " Feature " is becomming universal on all monitors, so as we go to LED monitors etc. We will need to solve this problem if we want to use modern video equipment. More and more people will need something that fixes this as time goes on. Terry, What Time base corrector did you try ??? Did it help your video at all ? MR RCam, Thanks for the info you did give. We cant expect one person to come up with custom solutions for all our problems, even you deserve a life sometimes But I hope someone does, because if its at a resonalbe price, they will sell lots of these devices now and even more in the future as all video equipment starts to have this feature. Mike
  13. MR RC-Cam, The aiptek solution may work, but that just makes setup that much harder, and I have enough equipment that adding another camera that I have to turn on, set, and get working at every power up is not practical. Whatever I find, I want it to work as soon as power is put into with, without me having to go through a bunch of menus. You stated before that no one would want to pay 150 dollars for the solution to this problem. I can tell you from dealing with this problem over the years, I would gladly pay 200 dollars or more for a device that would fix this, so would a lot of other people that have posted on RC Groups asking for a solution. I think you dont realize how big of a problem this is for the FPV world... Its not just for Video Recorders that we need this fix, there are a huge number of LCD monitors and televisions that we can not use because of this problem. For those wanting to get the most beautiful and detailed picture for FPV, a monitor is way better than goggles. Having flown a lot with both, and just about every goggle out there, the flat panel monitor is so much better than even the most expensive goggles. Do you think that one of the small time base correctors like this would work ??? http://cgi.ebay.co.uk/Video-Time-Base-Corrector-Synchronizer-Color-Corrector_W0QQitemZ350256045255QQcmdZViewItemQQptZLH_DefaultDomain_0?hash=item518ce31cc7&_trksid=p3286.c0.m14#shId Or the AVT-8710 http://www.bhphotovideo.com/c/product/276891-REG/AV_Toolbox_AVT_8710_AVT_8710_Multi_Standard_Time_Base.html Mike
  14. Most LCD monitors go to a blue screen whenever the video is interrupted even for a split second, and it usually takes them a couple seconds to come back. Has anyone come up with a way into fooling a monitor that there is always a valid video signal when the wireless cuts out for a split second ??? A solution to this would open up many new devices for FPV use. Thanks, Mike
  15. Would a Time Base Corrector keep the Sync going ? If so that is only just over 200 dollars, and would open up a whole new world of recorders for us... It would be worth the price. Mike
