7SI - 6BNV, W6HEG - Gilbert, Harriet - Ellsworth - USA
"Came on the air 1923 in Boise, Idaho, as 7SI with a roaring five watter. In QST for October, 1925 7OB reported that 7SI would soon be signing a 6 as she was going to Salt Lake City to attend college. Her traffic total for that month was 19 messages handled. The following month her traffic total was 30 messages handled, and according to W2ZI, who supplied the information, this was quite a super total for those early days of relaying. Harriet's last call was W6HEG, her OM was W6GAT."

"On June third the seventh district Supervisor of Radio went to Boise, Idaho to hold license exams and to the surprise of the 'regulars' a girl of sweet seventeen entered and took the examination. Miss Harriet Ellswoerth is now 7SI, Congratulations, Harriet, F.B.! She is the second young lady amateur in the seventh district now, and is just as enthusiastic about amateur radio as any 'ham' could be..."

"By introducing her as W6HEG you may slightly raise your eyebrows, but by telling you that her old call was 7SI, many old-timers recall fond memories and dreams. You think of the gal who could make raw AC sound better than the prettiest of crystals. She is Mrs. Harriet Ellsworth Gilbert, YL of Ed Gilbert, W6GAT.

Almost eleven years ago, as a youngster of fifteen living at Boise, Idaho, she began the study of the Continental code. After listening in on a Federal receiver, CQs and code signals became readable. Being feminine, the inability to talk back was more than annoying. The R.I. came to town and after a frightful morning under his watchful eye she emerged with the second blue ticket issued to a YF in the 7th district. Immediately she was enlisted from among neighboring hams and a transmitter was built from the ground up. Her OM sceptically raised two forty-foot masts from which proudly swung a five wire cage aerial - that's what they were called in those days - with a seven-wire counterpoise beneath. The call of 7SI was assigned and thereafter the world became 7SI-conscious. It aroused so much curiosity that her photo was published in a radio magazine in October 1924. She is the YK who made one CQ last all night long. She broke hearts for a year and a half, then at the U of U in Salt Lake City she began anew under the call of 6BNV so that she could talk to the home folks and to the boy friend attending the U of Idaho who used 7JF's (W6FFP) station. But there are some things you can't do by radio, so while visiting in Los Angeles at a radio club meeting there was a great scramble and 6AIC was named the winner. 7SI was soon changed to Mrs. 6AIC. Radio became a side issue and finally simmered down to the BCL variety. A junior op arrived with background noise that drove the loudest signals out. 6AIC was again smitten by his former flame and he became W6GAT. W6GAT's first transmitter used the original five-watter of both 7SI and 6AIC. This brought back old radio memories, so Mrs. W6GAT took a new exam and was assigned the call W6HEG. They are often on the air together and they have had many pleasant contacts with old timers, from ZS2A to LU8BAS. W6GAT's brute strength emanles him to take the key away from Harriet when he is at home, but when he is away she is back at the old game of thump-thumping some poor guy's heart. Using HEG's own words, 'As a concluding confession I will say there has never been any sport or amusement which has given me more pleasure than amateur radio. I wish I could make more wives see what they are missing by not becoming a licensed YF.' And we echo: We, too."
