[Dxbase] Rotor Interface Problem / Hy Gain DCU-1 Continued

[JNMazzoni]

Still having problems .... cannot control the Hy Gain DCU 1 from Dxbase.

1.  I have checked the Activate  ROTOR 1 in the Rotor 1 tab
2. I have entered my QTH  +44.89 Lat / +93.11Lon in USER opt/ General tab
3. I continue to get an error message as follows

    The beam heading cannot be found.
    Make sure the beam heading is present in the summary window.
    If using arrow buttons make sure DX base has already set the current beam heading.

I was advised that ;

First make sure that you have it 'enabled' in the correct rotor 1 page3 on the User 
Options.
Second, the first time you use DXB, you must tell it where the antenna is.

I do not understand the second instruction. Do I type in an arbitrary Log & Lat ?

Can someone give more specific detail on this set up. It seem like it should be simple but I haven't had any luck.

Thank you
