Looks like I may have a problem with these components on the parent board; plug in the RV7 and the display goes erratic. The remote PTO works fine in daily use on my main TR7. A quick perusal of the situation looks like I will need to remove the DR7 and PTO to gain access to the parent board to check these components. Or. remove all cards and unsolder all pads on the bottom of the parent board. Any comments? Thanks,
Mike W4DL
