Here's my coverage indoors from my house with 3 meter wire and no ground. Markings indicate different coverage conditions and scale for distance is at bottom right. My house is marked. Since not to sure how to make videos and trying to drive and do this is not to safe you have to take my word that this is authentic! Also found that thinner 22 gauge wire peaked better on the meter that thicker 12 gauge wire did in same position...go figure.
Well, image won't upload here so go to part 15.org to see map.
I wonder if it's the Viglink problem we were having several months ago?
I see the map over on P-15 and that looks like nice coverage compared to what you have on FM, and from an indoor antenna too! Where you live would be a great place to broadcast to, with all those streets and the housing density it looks like you have.
I haven't had great success with an indoor antenna and 100 milliwatts, and over time I've tried them in different rooms, even the basement, with a Talking House and other hobby transmitters. The signals tend to go about half a block and fall to nothing very fast. That's what you'd want for a real estate sale, where you don't need the announcement going out to a whole neighborhood.
I think the best I've gotten from an indoor transmitter and antenna has been about .25 mile, and even then it seemed most of the signal was on the power lines at that distance, and just crossing the street away from the wires dropped it down. I did hear my signal weakly at 1 km from indoors on a car radio out of the blue, and there again it was possibly on the power lines since it was just heard in one particular spot.
Maybe your result shows that a manually tuned transmitter is better than the auto-tuned kind. Does the transmitter have a modulation indicator, or some way to tell how high your sound levels are, or any kind of built-in limiting?
Yes the Procaster comes in two parts. The transmitter and the processor or "studio" as it's called as if you had an outdoor set up the studio would stay inside and supply power and audio through up to 100ft of 4 conductor shielded cable but sine I am using it inside I just have the studio part with less than a foot of cable between the two.
The studio has the compression, line in volume, modulation adjustment, and limiting to prevent splatter. There's no modulation indicator but you can easily get to the volume of the other stations but if you go much higher than that distortion is how you know you are over modulating.
I always wondered about the Talking House automatic tuning and how accurate it is peaking the signal.
A modulator indicator is a great idea as the Procaster is supposed to go to 125% modulation but how do you know when you reach that.
I'll take a picture of the set up and it may not want to load here so I will try to get it to the max size that will.
To make the pictures better for posting, I recommend a program called Irfanview. It's an image viewer that can resize pictures and convert the format. If you have a large size bmp or png file that won't upload to the group, open it in Irfanview and save it as a jpg at default settings, and it should then upload, something I've done on MBCF, so I know it works.
