I got the PstRotator to work with OmniRig and IC-705 over WLAN. I’m using ”Icom Remote Utility” on Windows to set up the virtual COM-port. And I’m setting up OmniRig like this:
I had several problem getting the OmniRig to communicate with IC-705 via WLAN, but after re-installing to the OmniRig supplied with PstRotator (v1.18) I got it working OK. It is also working from SDR-Console V3.
So now it is possible to do doppler control of the IC-705 without any cables for true portable operations! See short video below:
My signal heard on almost all continents. 8 watt with IC-705, antenna EFHW. Band: 20 meter, 2021-03-28 daytime UTC. IC-705 connected to PC/WSJT-X via Wifi.
Important update! When using automatic control from PC then both the elevation and azimut is controlled (moved) at the same time. It seems that the Dell power adapter can not handle the current amp spike and turns off (overload protection I guess). I have now return to using my 13.5 volt power supply.
I have been powering my Rot2Prog rotor controller for my RAS rotor with 13.5 volt. This means that the rotor turns slow. My 13.5 volt power supply also has a very high idle consumption of 10 watts.
I changed the power supply to a standard Dell power adapter – LA130PM121 19.5V 6.7A PA-1131-28D1 130W. It can be found very cheap. I just cut off the power plug and connected the wires from the Dell adapter to the Rot2Prog controller wires.
Now the turning goes MUCH faster! The Dell adapter also has a very low idle consumption – under 0.5 watt. So it can be connected all the time. What I can see there is no interference from the adapter on VHF and UHF.
I highly recommend using the Rot2Prog controller with an old computer adapter. Below is a short video of how fast it is turning.
In IC-705 it is possible to set the MIC output voltage to 8V instead of default 3V. I have done some tests and I do not hear any difference with the standard microphone HM-243. What do you think?
