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.

no power output ? lawmate 500mw tx

Recommended Posts

Trying to figure out why I'm not getting any range on a small BW 500mw 2.4ghz lawmate 5v TX. I tried to guage current draw, and it's almost nill, around 100ma or less. Only run on 5v, Still getting a clear signal when very close, but 20 ft is about the limit. I can't figure out what I did to it, but it also dosn't seem to get warm like it used to. Is it posible to blow the amp end of these without blowing it up all the way?? I asume it's a brick at this point, I know BW dosn't sell these amy more, anyone with a hot tip as to who has the best price??

Ah well, thanks for the replys, I am looking at replacing it with this:


Which seems to have the same frequency set as my older BW diversity rx, or possibly this :


Which seems to be the same unit, but with a mic and power board built in, but would only work on ch 3. I find it odd that the same unit would be sold with 2 different frequency sets, but I supose since there are no crystals, it's all up to the programing.

Anyone have a difinitive answer as to in audio will work with these?? they seem to have audio carriers at 6 and 6.5hz for stereo, but I can't find a spec on the lawmate RX,

I am mostly looking at these units because of this artical:


Which states that the output dosn't sag with heat unlike the lawmate, and they are capable of 1w (30 db) which would be nice.
