So I received my units today and put them through a bunch of tests.
Firstly, the rubbish about not working well with immersion vTX's or on the band immersion uses is just that, complete an utter rubbish. Even on a 60" TV I cannot see even the slightest change in colour or image quality going from the FR632 to the Fatshark Attitude receivers. I also tested all channels on all 4 bands with a couple of different 32channel vTX units and all channels are perfect on all of the vTX's.
Range
FR632 (using a 30db attenuator) compared to
- Duo (V2 & v3) is nearly 6 times (no surprise there as the IMRC receivers are overpriced paperweights.)
- Boscam TS832 is more than 4 times (expected, this receiver only performs marginally better than IMRC)
- Boscam RC805 is about 3 times
- Boscam RX5802 is about 3 times
- Boscam RC5808 is about 2.5
- AOMway (the current leader in RX's IMO) is almost identical, when using diversity the FR632 is marginally better, when only using a single side of the FR632 the AOMWay is marginally better. (based on the receiver details these appear to be the same receiver units inside, I will know more when I pull one apart tomorrow).
I stopped testing the other couple of RX's I have here after testing the AOMway as the FR632 was performing as good as the AOMway RX which is significantly better than any of the other RX's I have at hand. It will be interesting to see exactly what RX is inside of these things.
Diversity
When the diversity switches there is absolutely no picture change/flicker, in fact I had to setup a couple of monitors to the different output to make sure the unit was switching between receivers (the unit does indicate which receiver it is using on the LCD display). A+ for diversity
Channel Selection
This is a full 32 channel RX with the full 8 channels in each band (unlike many other receivers that only have 7 channels in each band where the top 2 channels are the same). Each channel is easily selected as well as the bands, there is an autoscan function which scans through all 32 channels which will sometimes get the wrong channel in the wrong band due to frequency being so close, simply click scan again and it gets the right channel. There is also some propaganda out there that the autoscan will start scanning again if the vTX's is tuned off or power is interrupted to the RX, this is also complete rubbish, once it has locked onto a channel it stays there, even after powering off.
Overall
The units are small, sensitivity is awesome and the price is also awesome, the power input is 6v to 28v so you can basically plug anything into this thing and have it power it, my only gripe is the LCD display is a little small, fortunately my eyes are still good so no issues there for me
.
If you are looking to buy a new 5.8 receiver than this is hands down the only choice you should be making, buy a FR632 with confidence.
EDIT: One other gripe, you have to hit the power button every time you want to turn it on, so no "autopower-up" inside a ground station which is a pain (got rather frustrating actually)...
