Pedro,
No luck using HRD with the 746Pro. To get this to work, I've switched CAT programs. One I've found that works is Commander (
http://www.dxlabsuite.com/commander/). Their list says they support IC-7000 as well.
This program is not as nearly full featured as HRD, but it allows me to do what I want to do. To connect, click the CONFIG button in the interface and change the values under the GENERAL and PORTS tab to match your radio, etc. One thing I've found that helps is to change the "Command Interval (ms)" to "50." I am still all on my local network, so that may be too quick for a remote configuration. I will be testing remotely for the first time today and will report any changes.
The one thing I don't like about Commander is that there are not a lot of software controls for the radio's specific hardware. When connecting to my 746Pro, I can't control the AF Gain when first starting Commander. The good thing is that Commander allows you to load in "Slider Definitions" which allow you to tie Commander's 8 sliders to hardware controls on your radio. To see the sliders, open the config window of Commander, go to the GENERAL tab, locate the General panel, and make sure the "Show User-defined Controls Panel" check box is checked.
Instructions for programming the sliders in Commander can be found here:
http://www.dxlabsuite.com/commander/Help/CommandSequences.htm and the reference I used to locate the structure of the CI-V commands is found here:
http://www.plicht.de/ekki/civ/civ-p0a.html (specifically section 4.2). Many thanks to Commander and Ekkehard Plicht and his great reference!!
Commander experiences none of the issues I've seen with HRD. I've had great success with HRD in other configurations, but I've had no luck with HRD and Remote Rig boxes.
If you test Commander out, let me know how it works for you.
The problem was probably due to the way HRD was sending/receiving commands. It is probably not an issue with the RRCs as once HRD experiences its "timeout", Commander has no problem establishing a connection.
Good luck with your setup!
