I am using the Procaster now to replace the recent Talking Signs I was using.
I have it mounted on the wall in the kitchen and the 104" antenna horizontal across the room in front of the window. I have substituted the stock antenna with an equal length of wire as the 3 section aluminum is hard but not impossible to use indoors. Gerry at Procaster told me the 3 section aluminum is exactly the same as an equal length of wire electrically.
No ground. An electrical ground is had through the 3 prong wall supply.
I have the computer, studio interface, Schlockwood on a shelf under the window but I am currently using just the included studio processor compression and limiting giving power and audio to the transmitter with 5 ft of the 4 conductor shielded cable and a Fosi 3 band EQ headphone amp for extra audio tone control between the computer and studio. Working nice.
Audio is pristine. As good as AM can get and with a decent receiver with proper band width With a Sangean MMR-99 for example the Procaster can sound like FM or close to it with a bit of tinkering with EQ at processor.
Here's a picture of the simple set up and another of my tested range. Small circle is good and larger is weak but heard.
All plugged into a UPS backup and this will run for 4 or 5 hours in a power outage. The laptop has it's own battery back up so it's not in the battery supported outlets. The range is what can be achieved from indoors with a set up like this.
A little trick when posting images here, when you use the dialog box to post an image it puts it in a little box that doesnt allow you to zoom in. But if you post the picture with img tags instead then the picture is displayed in a way it can be zoomed into if so desired
Example
Hmmm.. looks like you dot even need the image tags here,just paste the image link

Well that's weird, when I use img tags (as in the first picture)it shows the tags n the post but it makes it so you can click to zoom, but if I just past the image link without tags (as in the second image above) it still post the picture but its not clickable (thoughbyou can right click and open in new window).
Weird
@richpowers I just posted the images right from the camera, files from computer. Click on the picture here, it gets large enough with original resolution.
