I have an HP pavilion 15 laptop w/Windows 10 and No Hum. Use it with my FM TX and internet stream.
The BC-1004-C receiver I use for monitoring and entertainment was past due for an alignment. I did a complete alignment on all bands plus the crystal and phasing circuits, about 50 coils and caps to adjust but it was well worth the effort. It sounds great and hears very weak signals.
Repair: My AM station was beginning to sound as if it was under water and the compressor/limiter VU LEDs didn't look right. I've seen this before and went right to replacing a power supply capacitor in the unit and it is as good as new (acutally better since it now has a good quality cap.). Damn those crappy caps that seem to flood the market and find their way into audio equipment.

i got my 1630khz carrier current up and running which seems to be working good. looks like i am covering 5 apartment buildings in the complex with a city grade signal via the power wiring on the neutrals using an isolated ground. according to my lpb coupler metering i am running about 2 watts into the coupler.
You are probably covering more population than I cover in my town!!! That is nice!
each with about 30 apartments
Nice situation I bet it's better than what micro FM broadcasting can do. Wish I had the eyesight and skill for CC cuz I'd get an amp for my TH and try that as well as FM.

Looked it up on the HP website and yep, it's an Integrated Realtek ALC 656 Here are the specs on this model HP P6-2108p desktop pc.
It has more than paid for itself over the years.

Glad to hear you have a very usable signal there. Congrats!

Carrier Current broadcasting is pretty awesome, just a little more expensive, with the higher output power from the finals and more hefty tuner that's needed to match the transmitter to the line, compared to 100 milliwatt stations.
It might be something better to build, if you can, since there's a lack of new equipment for Carrier Current use.
I can't build so I'll have to keep looking for such equipment.
Right now, I'm doing yet another music show on 1650 AM, Radio Free Connecticut. Rock ballads/slow jams until around 10 PM eastern! 🙂
I was experimenting with an easy listening segment late yesterday evening. I set up the rotation for what was supposed to be an hour long test. It was still playing this morning....
Not a big deal, but I did get a few comments during breakfast at the cafe.
I also cut some more station ID's for the Holidays.
I need to go outside today and do some transmitter work. It is supposed to be 74 today, tomorrows's lows are supposed to be in the middle teens! Yuck!
have the Wheatstone A-50 traded to an Optimod 9100 Stereo AM Processor soon. so the optimod will be on the carrier current and the soon retired Inovonics 235 will go on my 15.219 remote site
in case the primary deal fals through so it appears either way i will wind up with an optimod 9100 stereo for my carrier current station 🙂
the inovonics 235 will be relagated to an auxiliary part 15.219 site with my procaster or as a backup to the optimod.
