If he 'could' see the sun you mean, then he could get a Westing but what about the Latitude ?
By all accounts the only direction which was showing cloud and could obscure the sun was to the Northwest of the ITASCA..
There was something wrong with the aerial side of the Receiving set up but she had received the letter A's on the DF Aerial. She knew that ITASCA was receiving her calls.
What beats me is why they did not keep trying with the DF unit or set up a "Yes/No" communication using the DF set using Morse "Y" and "N"
