    Hi All
    I am having trouble here I have a RigBlaster pro. Now here is what happens. I installed a new ground rod here and grounded all of my equipment and also installed a new amp the TL-922A. I use to use an Ameritron AL-811H. My RigBlaster was working well until I did all of the above. Now it will key up the rig but as soon as I put 10 or 15 watts output the Rig blaster goes into rec. and will not Xmit again. I have to reboot the computer and still have the same trouble. I reinstalled all of the drivers to it. I also tried to ground it. I do not know what is going on.

    Oh one other thing if I leave the rig off the RigBlaster works well. I have tried to remove the Ground from the rig and still have the same trouble. Can someone help me out with problem?

    Thanks

    Sounds like you have stray RF (common mode? coming in from coax?) in the radio shack.

    What are you using for an antenna?
    Are you using a vertical antenna without choke balun OR a 1/4-wave without the required radial field?

    Here is another good one. When I put the amp in tune. I hear the brake on the rotor disingage.

    HELP

    Yup -- you have got RF in the shack.

    Potetial sources:

    1. Bad coax cable -- jumpers used in shack, main coax to antenna, bad coax connectors.
    2. No usage of cheap (ugly) coaxial balun or choke balun at Mosley TA-33M feedpoint (up the tower).
    3. May have to use ferrite beads on some unshielded cables in radio shack.

    Yes, a quality balun at the TA-33 feedpoint can be beneficial. Is the SWR on the antenna decent? The traps need to be cleaned out every few years or you get amazing things growing in them - I suspect the fact that the plastic lets light into the traps and increases the growth of plants. We had a problem with spider webs in ours - the young spiders would get in through the weep holes, spin lots of webs, and eventually die of starvation, leaving the webs and their bodies behind. After cleaning the traps and rebuilding the antenna, we added a quality balun at the feedpoint, and it seemed to be a big improvement.

    The addition of the new ground may have actually increased your problem by providing a return path for the stray RF in the shack. My RigBlaster Pro has a number of ferrite appendages in it's leads for this purpose, too. The split ferrites sold at Radio Shack work, but are ugly. IT would be best to find the source of the RF, though, and fix it.

    You don't need the amp for PSK31 and most soundcard modes.
