Thank you very much for the replies.
The way the units are shown in the photo is not the way I have been doing testing. It was just a way to have both units in the same photo.
I will keep in mind the suggestion of antenna orientation when I try more testing. I did not take note of the orientation when I made the previous tests.
Do you think the antenna are part/all the cause of the trouble? Do you think it would be wise to order another pair of antenna? perhaps of a different design?
I have very limited test equipment so I can't really see what makes a difference except to use the receiver and go by what it says.
Is there anything else I can try?

Thanks again,
Gord
