Avoiding adding of the connector.


You can avoid adding the 2pin connector and just use a spare pin on the main connector == the 'S' pin of the "BATT" position.

In some board revisions it's connected to the "pairing" slot and one will need to cut the trace between those.

Backhos did you have any luck with reading the rssi voltage?

i switched to chainlink LRS, but i think it's been done.

I saw your voltage measurements, did you make any more voltage measurements? Or is still that behaviour that you stated..

it always behave like that, i know Rmilec LRS is compatible with those numbers.

Just to make sure....So for 100% reception 1.07V and for 0% voltage that is over 1,25V? In between would you say linear voltage drop?

Edit: I have the receiver from hobbyking, does it make any difference? and my 9x is the v2 from HK..

i dont remember, this was a year ago i think and i dont have this rx anymore.

Anyone got any luck? The RVOSD reads 1860-1870 as long as i got signal and drops to 400ish when i turn it off. Even when i walk out of range it is 1860-1870 until it looses and goes to 400ish

does this mod work?

i apologize for resurrecting this thread, but would hate to go through the trouble of ruining my receiver just to try this out.

thanks

go ahead and try
I am in the same boat... late to the party. I am going to attempt this mod for use with one of the hobbyking sub $50 OSD systems w/ GPS. I am in over my head, for sure. I dislike soldering, and am no good at it, so this is asking a lot of me... Hobbyking product suggestion. 9x Rx with RSSI output... $15

instead of waiting for a response i went ahead and did the mod.

my recommendations are as follows:

1. find the smallest tip soldering iron that you can

2. spend the absolute majority of your time prepping. ensure all contacts are clean and glue the thin wire to the board prior to soldering. this is your strain relief, and will also position the wire for you.

3. strip only the bare minimum that you need, to make a solid contact to the left side of the resistor.

4. touch the solder to the iron tip before touching the joint between wire and resistor.

5. keep your iron on low heat!!!

6. the actual soldering should take no longer than 4-5 seconds.

7. done!


It appears to be working. good connection between rx and tx = about 1.05v while a poor connection is closer to 1.25v. When transmitter is turned off, the line voltage drops to .8v. this is not optimal... but no big deal. You are only interested in the values while the transmitter is on anyways...

Hey guys, thans for your interest,

Like i said i dont have this system anymore, i use Long Range System Chainlink, but the result should be the same i was getting.

And btw, this is not a thread, its my blog lol

Hope you guys get it working

bakchos, sorry to have hijacked your blog. So, I did a test with the RSSI output from the Turnigy 9X into my DragonOSD. I copied your mod method, every step of the way. Unfortunately, it appears my RSSI signal is fluctuating very wildly when i look at it on my OSD video. between 60% and 100% when rx and tx are right next to each other and not moving. I already calibrated it, so thats not the problem. Is the RSSI out from the Rx not buffered? Is that why my readings are so unstable?

i am pretty sure you need a cap and a resistor to create a buffer, look at the poor man osd thread "remzibi osd" there is information about buffer for rssi.
