3DR telemetry no longer supported by 3DR....options?

I have been using the 915mhz telemetry v2 units with my Pixhawk for a while now. One of them is not giving the range that it used to and I need a replacement.

I varified the range with the use of my Fighting Walrus iDrone Link and one unit is getting about 100m range while the other is getting good signal to where my hexacopter is just a spec in the distance.

Problem 1:

I can not get hold of Fighting Walrus any more. They have not answered my emails since about October of 2015. I am assuming they are no longer active? (also no updates to their iOS app for almost a year)

Problem 2:

3DR are no longer making their 900 or 433 telemetry units. (verified vie an email to them)

"Hello Justin,

Thank you for contacting 3DRobotics customer service.

We apologize for the inconvenience. Unfortunately, we do not have the Telemetry available anymore since they have been discontinued, both the 915 and 433."

I am using a Nexus 7 v2 Tablet with the Tower App (great app by the way)

Question:

Other than the $250 long range 900mhz kits (I don't need/am not allowed to use super long range) or $10 knock 3DR off kits from China (gamble as to whether you get a good one/no warranty), what options are there that are "PnP" ?

I am using a Taranis Plus TX with x8r RX and could use that telemetry but then there is no way to load missions in the field.

Thanks for input

  Bill,
  
  Thanks mate for the link. That looks a little over my head and by the looks, I will need a spectrum analyzer to do the tuning. Am I reading the post correctly?

    You do need a Spectrum Analyzer, but that is done using a 'Software Defined Radio' module you can get ~$10 see http://www.ebay.ca/itm/NEW-USB-DVB-T-RTL-SDR-Realtek-RTL2832U-R820T... as example.
    
    You install the FW supplied in the post, tune the radios to be a matched pair. The setting is saved permanently, then reinstall the standard FW and you are good to go.
    
    You can also turn the SDR module into a desktop ADS-B receiver when you are done

    I actually use mine to listen to the FM Radio ;)

Have you considered using a bluetooth link to your tablet to load missions, and use the frsky telemetry to check yoru battery status'

  G'day Sergio,
  
  Thanks for your input. I have toyed with the idea. I guess I should check into how much data the Taranis will actually give me. I like to have Amps, Volt and altitude as a minimum. I already have timers set on the Taranis.
  
  Can you give me a starting pointer to a BT link that works directly with the Pixhawk?
  
  This one or is there a "better link"? http://copter.ardupilot.com/wiki/common-mission-planner-bluetooth-c...
  
  Something that my Nexus 7 will connect to easily?
