Seriously, it can't.

Our internet is so wonky now who would notice?
It's there most of the time but just not at the speed it should be and i am tired of telling TVS Cable to fix it.

R0ck95seven: I feel your pain on the Internet.  Wen I lived in Elizabeth City, NC My net went out all the time.  speed was never constant and upstreaming to my server (Located In AZ) was not able to stream without cutting in and out and an error message saying that my encoder could not send data fast enough (When I Had SAM).  Had to go wth cellular Internet a lot of the time just so I could run my station.

 

As far as CC I wonder if I should have my inverted L wire face towards the electrical box?  How your able to do this is a mystery to me and I'd like to be able to do carrier current as I can't put up an outside antenna.

But,

I figured something out with my setup.
I wanted to use my netbook to automate the station so i took it off of the desktop pc and was running it from the netbook. Guess what ??

The netbook like most portable computers, has a crappy little cord with a switching power supply but it does not have the third ground prong like the desktop pc.

Therefore, there seems to be one of my theories proven. That the transmitter is getting ground from the audio connection to the PC which in turn comes from the power cord that employs three connections, hot, negative and ground.

Also the transmitter is using the same outlet as the PC.
When the transmitter was connected to the netbook, there was a change in the route the ground takes that was probably no longer there since the netbook is wired differently.

I had to retune the SStran when i connected it to the netbook the same way i tuned it when it was on the pc.  I lost coverage, a lot of coverage when on the netbook, returned to the pc and tuned up, coverage from the power lines returned.

The desktop runs Zararadio, the netbook runs VLC player.

Part of the mystery has been solved...

The SSTran grounds 3 ways, The Power Supply, The Audio Line, and antenna ground. These can be enabled and disabled via internal jumpers.

I have the SStran set to bypass grounding to the power supply, currently grounded to the screw on the outlet cover. Same reults, same coverage.

The Whole House doesn't put out enough power for carrier current.

You mean Talking house as that is AM and Whole House is FM.

Should not be used on Carrier Current.  Physics as Rich would say.  Wavelength to short. CC better at the low end of the AM Dial

So, I am still considering options.  But, I did gain some information, nothing terribly useful yet, but nonetheless good conversation.  Ran into a AM broadcast station owner, he was encouraging.  And I was discussing things tonight with a ham radio friend who has a lot of experience from years ago with CC.  We discussed pros and cons and problems etc.  Not a lot of new revelations, but it was refreshing to discuss it with someone who is knowledgeable and willing to help.  He even made a suggestion of how to "couple" without direct tie in.  I will elaborate on that after I try it (sounds simple).  Further, there were suggestions for ensuring compliance and is checking some of his connections for possible equipment.

As a side note, there is a complete CC system on the big E auction site that looks interesting.

Lots of good comments here about Unexpected CC. 

I trudge onward...

My bad! Misread your post legacy. The talking house easily cruises the power lines, typically all by itself thanks to the way the power supply is wired.
