Yaesu FT-847 Doppler Control with PstRotator

I want to work amateur radio satellites, especially those with a linear transponder (SSB/CW). I worked satellites about 10 years ago, but the urge to do it again has appeared. As I have never been able to control the doppler shift, I wanted software for this task. 

The program PstRotator can manage both antenna tracking and doppler correction. However, the configuration of PstRotator was more difficult than anticipated.

The software runs on my PC under Windows 10 Home (64 bit). PstRotator and OmniRig are installed as usual. Hardware and software is connected as shown in this sketch:

PstRotator controls the rotators and the FT-847 transceiver.

OmniRig is a driver for COM-ports. It enables several programs use the same port. This is a benefit, because a log-program often needs access to the same COM-port in ordet to read the transceiver's frequency and mode.

PstRotator is like a "Swiss army knife". It controls both the rotators and performs doppler correction. 

My rotor controller is ERC-3D. It controls both azimuth and elevation. ERC-3D was made by DF9GR, but the controller has been removed from the market and is now obsolete. It is replaced by the ERC-M.

If you would like a detailed description how I configured PstRotator and OmniRig, you can find a PDF-document on my homepage: oz1bxm.dk/PstRotator.pdf
