Hello everyone!
I wanted to confirm that if I can use two telemetry radios of different range i.e. RFD900x for controlling the drone in guided mode(which gives about 10km range) and Holybro Sik Telemetry radio V3-100 mW 433 Mhz for RTK corrections with Here 4 Base and Here 4 RTK?
Due to limited range of the second telemetry, will the corrections take longer time?
Regards,

What do you mean with this second question. As long as the data are received and not corrupted RTK will work correct but on the edge of the range if data going lost RTK will not work.
I have two telemetry radios on the drone. One is RFD900x(approx 10km range) and another is Holybro Sik Telemetry radio V3-100 mW 433 Mhz(approx 300m range). The ground unit of RFD900x is connected to a companion computer(i.e. RPi) which is used to send missions to drone via guided/auto modes. Where as the ground unit of Holybro Sik Telemetry radio V3 is connected to GCS with HERE 4 Base and HERE 4 RTK(with Mission Planner). I’m using TELEM1(SERIAL 1) port for RFD900x and TELEM2(SERIAL 2) for Holybro Sik Telemetry radio V3 on the drone. My doubt is will RTK Float/Fix status disappear after the drone is out of Holybro Sik Telemetry radio V3 range. I have to use two telemetry modules due to operational constrains.
As I said before, if you lost the RTK link than you also lost RTK Float/Fix. RTK data are needed as live data continuously.
We have installed 3 Telemetry radios (433Mhz, 868Mhz, 915Mhz) on one small area drone, opened 3 MPs, and all work well. Don’t ask me why we put 3 Telemetry Radios on one drone. RC comes with 2.4Ghz and 5.8Ghz.
You can use one instance of mission planner and have multiple connections to one vehicle.
One instance? Once a COM port is connected successfully, how are you able to start the next COM port connection using the same MP in Windows? Hope you can show us with a video.
