Re-testing the RC302 Because of the output issue with the RC302, I decided to open it up and get it fixed. This involved replacing both the output transistors. In the process, I took pains to clean up what looked like residual flux/solder-paste on the board, with methylated alcohol. After this I ch...

I should mention that we are looking at a possible USD19 price increase on the DOSD+ V2 soon. This will bring the price of the DOSD+ V2 to USD159. The reason for this increase is to make it more worth dealers' while to carry the product. Otherwise the margins are too low and I don't want to low-ball...

Lawmate RX-2460CK (Comtech FM2400RTIM8) This very popular receiver has been the workhorse receiver for 2.4GHz FPV and has been around for a long time. It is the biggest among the receivers tested and sells for around USD50 (NGHobbies) under various labels. It draws a hefty 240mA and runs pretty hot...

Video performance testing was done with a very weak RF signal being transmitted from the other room. The measured signal strength at the receiver is between -97dBm to -99dBm. All the receivers were tested using the exact same antenna in the exact same spot (+-1mm). In so far as was possible, everyth...

2. Added hardware identification

A number of useful conclusions can be reached with the results from the tests above. 1. The choice of camera can determine your UHF and GPS performance. Some cameras, namely the NextChip reference design based ones, generate high levels of RFI in the UHF through to the GPS bands. In some cases, the ...

This project has now been superceded in all respects by the DragonOSD+ project.

Of the seven cameras tested above, the four that are most similar are the:- VSN500 VSN505 FH-25HD ?? (unknown model) Cameras 016a.JPG Apart from the VSN505 that runs on 5V, the others all run on 12V and appear to have similar specifications. These similarities aren't just restricted to the specifica...
