Analog : The default setting is RSSI output
Working with higher version RF module, Analog port control data can configured as
your radio output CH1-CH10.1-2 ms pulse width corresponding to 0-3.3V voltage

Analog output is Ok. I didn't see it at first on the receiver pins. Very good.

What are others opinions on these posts from Mictronics

2. Harmonic: 1200-1410MHz
3. Harmonic: 1600-1880MHz
4. Harmonic: 2000-2350MHz
5. Harmonic: 2400-2820MHz
6. Harmonic: 2800-3290MHz
7. Harmonic: 3200-3760MHz
8. Harmonic: 3600-4230MHz
9. Harmonic: 4000-4700MHz
10. Harmonic: 4400-5170MHz
11. Harmonic: 4800-5640MHz
12. Harmonic: 5200-6110MHz

The RF output power will be reduced for each harmonic band by several dB but, since you operate the TX near your video receiver I would expect serious problems with video reception.

No matter what I say! There will always be a nerd claiming this wont work in any way....

I'm not the builder or behind the product but I know it have been tested for some time, also with Video link 900, 1.2 Ghz and 2.4 Ghz in the FPV setup without any problem.

I will make a FULL REVIEW soon.

some errors in the manual.
A. Keep receiver antenna straight, and about 90 degrees to each other
picture reads 180 degrees

I love my lrs but to not have a big metal box attached to my radio would be very very nice.

Turningy ?

Does anyone know if this can click into Turnigy 9x? Seems like they are visually compatible?

Give it one more week and I should have mine in my plane

I will also test this on the ground with my car to see how long range I can get on ground.

lol... when you can beat them, join them! good though, a quite range of UHF modules already, competition is always good, a nice way for every supplier to make better improvements.
