Now, here's one "in reverse"! Back in 1960, when I was a Novice, I had my station in the bedroom. Second floor, just a short distance to the roof gable to the northern end of my North - South 40 meter dipole. Rig was one of the venerable World Radio Labs Globe Scouts (a 680-A). Yep, my pride and joy ran a neat 65 Watts on cw. And, I was having a blast that summer!

One day, as I started to call CQ, I thought I noticed a voice in the reciever. Now, I was using the Hallicrafters S-107 as my sidetone monitor; just kept it unmuted and wore headphones, so I didn't bother anybody.

Well, at first, I just figured I'd been mistaken. Then a little later, there it was again:   A YLs voice, but it didn't sound like she was talking to anybody....at least in the QSO sense. Then it was gone again. So, I just figured that it must be somebody whose VFO slid down the band, right? I was operating on either 7158 or 7160 (the two crystals in my possession), so I figured it was possible for somebody to bump the knob and be 40 Kc down the band.

Well, I didn't hear the voice again for a few days, so I forgot all about it. Then, one afternoon, there it was again. So, I figured I'd better investigate. That's when I noticed that I was hearing this YL only when the transmitter was on, and only when the key was closed. Hmmmmmmm.

A few more minutes' listening also identified the "YL" .... It was my Mom!

Now, how was that possible? I'd read about TVI and knew it also could happen that people'd hear hams on their radios, but hearing their Mom's on their radios? Nope, never heard of that one!!

A bit more investigating proved that what Mom was saying was in regard to a part-time job she'd taken with the local newspaper. "You say she wore a white, full-sleeved gown and .... her flowers were...." Well, you get the message. There I was, phone-tapping our own telephone, listening to Mom gather reports on weddings for her newspaper assignments! And, I only could hear the conversation when I had the J-38 closed. And, I could hear only one side of the conversation.

Now, I know that the solution has to be some sort of audio rectification, and that it wasn't some mysterious wire-tapping, etc. But, I've never been able to figure out EXACTLY how it was accompished. As I said, my station was on the second floor of the house. Mom's phone calls were on the first floor. We did have a second phone upstairs, but it was a fair distance from the rig.

On the other hand, the phone line running into the house was almost directly below the northern end of my dipole, although probably a good 20 feet of vertical separation. The center of my 40 meter dipole was 32 feet to the South of that point, which would mean that my coax would have dropped about 10 to 15 feet vertically, then traveled about 20 feet to my bedroom window.

And, I'm trying to recall if I had the rig grounded; I'm sure I had it grounded. Dad wouldn't have been too happy otherwise, HI! The ground wire would have run about 12 to 15 feet vertically from that window to a short groundrod immediately below. And, the ground wire would have been almost parallel with the phone drop, separated about 8 to 10 feet horizontally. Well, as you can see, I'm trying to account for some sort of coupling, but how did the phone's audio get impressed on the Globe Scout's RF and detected in the Hallicrafters receiver?

Any ideas?   de K3LBP   Larry
