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:

This is a very fast guide to set up the IC-705 with UISS for sending AX.25 packets and APRS.

1. Download and install UISS. During installation, install the Soundmodem software TNC.
2. Download the file ptt-dll.zip from Soundmodem webpage. Unzip and copy the files to your UISS folder.
3. Change the CI-V address on your IC-705 to 94h as we have to use the settings for IC-7300 in Soundmodem.
4. Set the radio to FM-D (Data) and select the frq for APRS (in Sweden 144.800 MHz).
5. Start UISS
6. Setup UISS with your callsign and your location:
   
   
7. In Soundmodem, set the Sound Card device to your IC-705 USB audio card.
   
   
8. In Soundmodem, set the PTT Port to CAT and radio IC7300. The COM-port should be the one that IC-705 uses for CI-V.
   
   
9. Now you should be able to see traffic
   
   
10. Now send your first APRS Position. Use digipeater if you like.
    The IC-705 now sends your APRS location.
    
    
11. If everything is OK you should be seen on aprs.fi
    

This is a memory group file over satellite frequencies for Icom IC-705 and CS-705 software. It is not complete and will be updated. Feel free to use it, change and add.

The memories for FM transponders are used like this:

• Channels named with satellite name, for exemple ”PO-101”, are used in split mode. This channel can be used when using the IC-705 for portable operation or without an extra receiver .
• Channels named with satellite name and Uplink, for exemple ”PO-101 Uplink”, are used only for uplink (not split). This can be used with software like SDR-Console v3 (external radio) or if you have an extra receiver.

Import the memory file into CS-705:
Note! Be sure that you not overwrite anything in your IC-705 when cloning. Make a backup of your current settings!

• Create a new memory group
• Mark this new group
• Choose File->Import->Group and choose the .csv file
• The memories will now be imported to CS-705
• Clone to your IC-705.

Today, 2020-11-11, I made my first satellite QSO since 1993 (when Oscar-13 was alive). My two QSOs was via PO-101, IC-705, 10 watts output to 13 el X-Yagi.
