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.
Thanks for all the explanation! I also removed the 75 ohm resistors as you advised. I compared the video level output to one with the resistor still present, and with the oscilloscope I have there was no visible difference. But it is indeed good idea to unload the video amp a bit, thanks for the tip. Maybe I should add this to the video explanation. Now that transistor is identified it's maybe also possible to find an alternative for this transistor that would produce higher level output signal. Anyway, at this point I am leaving my FR632 receiver with both transistor and resist

Hello guys. I've actually found the issue with this receiver and was able to fix it... So after I’ve bought the FR632 40ch diversity receiver I encountered the issues with distorted image on quick light changes. Seller confirmed it’s faulty and sent me an replacement, but the replacement receiver had the same issue (as for a lot of us). I got my money back, and after some search I’ve seen that
