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. Hello! What is the 5 pin SMD in the top right corner? I think I have this blown, is this a 1.8V regulator? I need to know maybe the marking on that chip? Also, there is another 5 legs regulator on the other side of the board, what is the marking/model/type of that one? Thanks in advance!
  2. Question is... I still got 0.75V output on the other 2 outputs, on the bottom pin of the 3.5 jack headers for AV-OUT on RF.A and RF.B. I don't use those for google obviously, but I use one of them for recording the stream to my phone (working as a DVR). Anything else I could do to fix this, or do I need to fix this as well? I've got the recording working, but can't say if the issue is still present on the recording or is not affecting it.
  3. I’ve done the mod described in previous posts, I’ve removed the thing with 3 legs, the 75 ohm resistor and soldered a 470uF capacitor (I had only low ESR type ones). Pic attached. Preliminary testing seems I got rid of the screen tearing and image skewing when changing rapidly from dark to light on camera.
  4. When looking for a direction coupler what should I look for besides the frequency range it is supposed to work with? I see this shop (with obscene prices and even more obscene shipping costs to me): https://www.ebay.com/itm/DC-16-OSM-4-8-GHz-30-dB-SMACoupler-useful-2-10-4-GHz-Tested-w-plot/181808338228?rt=nc&_trkparms=aid%3D222007%26algo%3DSIM.MBE%26ao%3D2%26asc%3D52935%26meid%3Dcbd9f5fe713248fa8e06edf84bd8b858%26pid%3D100005%26rk%3D5%26rkt%3D12%26sd%3D382501382270%26itm%3D181808338228&_trksid=p2047675.c100005.m1851 It also has something like a graph, how
  5. First, I already ordered the ImmersionRC RF meter v2 version which is supposed to have an internal attenuator. But I still want to build my own DIY version for me and some for my friends, so that means I need that attenuator anyway as well. I went down this “what is my RF value” path because I had some terrible issues with my Turnigy i10 transmitter, I get hit by failsafe a lot, in less than 200 meters and after getting my quad behind some small buildings. My transmitter is supposed to output less than 100mW to comply with EU regulations, but I believe it is actually doing even less.
  6. I'm looking at a couple of attenuators on banggood and the search result comes up with a couple of Excellway attenuators, and they have like: Attenuation: 20dB, 10dB, 6dB, 3dB. Max. Frequency: 6.0 GHz and all for about US$7.60 There are reviews for all, and a couple of people posted measured values for each of them and some graphs. Question is, which one should I buy for usual testing, should I get the 10db one or the 20db one? I've seen that some attenuators like the one from MiniCircuits or the one from the RFMeter V1 had something like a radiator around the body,
  7. I just ordered a RF Meter from ImmersionRC but is the new version, with an included attenuator. Can I use that one to build the DIY version I plan to make afterwards? And another question, can I use this tool to measure the signal strength and if I have any losses across my home TV cable which uses a couple of splitters down the path? I know that the TV cable is for 75ohm, not 50ohm like in FPV, would that be different to measure or I can use the same setup?
  8. Hi there. stumbled into this thread while googling for potential issues of this receiver. I never thought my receiver would have problems, but I’ve noticed a different image between my googles (FR632 40channels paired with a Quanum V2 headset) vs. some Eachine diversity headset. Still not sure if the issues are related to the antenna or some other cause, but I dont experience the issues described in the OP. I only have some noise... some horizontal lines that dont appear on the Eachine receiver. Anyway... another question, would be possible to add a minimosd directly to the
