Hey all,

Anyone here using a ghost module to control a non ImmersionRC VTX? I'm using a Foxeer extreme wired to the receiver but I'm unsure of the power level as the levels are not the same. The Channel and band controls work great it's just the power levels that are in question. I set the thing to max but the VTX never really gets as hot as you'd expect at that level. The signal definitely get better or worse depending on the level set. I think I'm going to have to go back to the flight controller and BF.

Any suggestions would be welcome

As long as the vtx uses Tramp telemetry then it should work.

Can you confirm you are using the correct vtx tables: https://download.foxeer.com/FOXEER_Reape...Table.json

I use Ghost and there are several ways to control vtx power but it’s either one or the other and not both.
Are you wanting to use the ghost module or your sticks on radio?
How is your vtx wired up?
If vtx is changing power the led color and number of blinks should change.

I think the simplest way is to use FC and copy/paste tables into cli and then you can use stick menu.Also betaflight lau scripts is another way to control vtx channels and power,plus betaflight settings too.

Thanks guys, 

I am not using the beta flight tables. I am using the Ghost module on the back of my radio to change the vtx channels and bands which I can verify with the lights.

Only thing is the power led is either solid for unlocked, blinking for locked, or off. Again this is a Foxeer VTX and not an ImmersionRC one and the power levels dont correspond.

Thanks again for you input. 

I'm thinking of wiring it to a uart and using the tramp tables just thought I'd try it this way first. I prefer the tramp to smart audio as it's much more consistent. I also prefer the button method to smart audio on my Rush Tanks as they like to do some weird lock down on the power and I've been in the field unable to use them.

  I agree that using the older way with uart is the most accurate way to go and simplest too.

   I am guessing since betaflight 4.3 is still fairly new which was needed to unleash Ghost there will be future firmware or features added.
  
   I think the Ghost module control is more for the newer ghost hybrid vtx/rx but I am guessing.
 I have two of the hybrids and they work with the ghost module without any additional soldering or work.

Ok so when adding it to the uart it was set at 1.5w while the ghost module was set at 350. this is the second form the highest setting on both. So I would like to infer that the settings would be as follows with the module setting listed first and the vtx second. Both the module and the VTX have the same number of power levels so they should line up but without being the same as listed i.e. the 1st level on the module is equal to the first level on the VTX the 2nd is equal to the 2nd and so forth and so on.
off=pit 1mw=25 25=200 100=500 350=1.5mw max=2.5

Thanks again for everyone's input



The VTX still isn't really getting that warm even on 1.5mw though and has less range at max than my Tank at 600mw

The Rush VTX’s produce a fairly clean signal.

I had a similar feeling that my Tramp HV had a more cleaner signal and range at 200mW compared to Flywoo Goku at 800mW.


Do the LED’son the vtx flash or blink differently when you gradually increase the vtx power? Basically on the Reaper every time you change power levels you should get a difference number of LED flashes.

 Are you using the Foxeer Extreme 2.5mw ?
 I thought you were using the nano.
  It could be locked?Vtx get extremely hot even my Rush tank gets hot on any settings over 25mw.
  If it’s locked it’ll never go over 25mw depending on what vtx tables are used.
  Here’s a good video explaining.
  

Well I only thought I had unlocked the VTX. It now blinks the red LED the corresponding number of blinks for each of the power levels. Still not all that warm at 1.5W and range aint any better than my Rush tank at 600mw.

 I’m curious if Foxeer has some QC problems because JB did a review on one and his only put out half of what it should have.
    
   I’d suggest contacting vendor and/or Foxeer.

  I think it should get so hot it would burn your wrist or inner forearm.
 It may not make a blister but it’ll hurt.
