Folks- Yaesu FT-1000MP MKV Field, US Interface Navigator, home brew computer. I have been getting a 'Network recieved bad checksum' error lately. Win-Test used to work fine, just since CQWW this has been a problem. Any ideas? It does it whether or not I am using the DX Cluster spots or not. Geoff, NE3K Sent from my iPhone
