Mark started the topic LITTLE KNOWN FCC EXCEPTION TO THE FM FIELD STRENGTH RULE in the forum Regulations / Law 2 months, 1 week ago
Go down to the charts for the rules for unlicensed use and get to part 15.231.
If your transmission is not all the time but temporary or intermittent you have double the field strength allowed.
Thought you were doing this for more than 7 years. Nice to hear the Procaster is working so well. In those temperature extremes does the frequency drift at all? You would know if you hear beating or a tone when the sky wave comes in with some other stations along with yours.
I use a Procaster now and my range is posted here if you didn’t…[Read more]
Sorry to hear about the transmitter.
You can protect the output from just that by installing a coil across the output from antenna to ground. The value if it’s an FM transmitter is 2.2uH. For AM I don’t know if that value will work as the different frequency range. It has to be a value that has a very high resistance in several megohms to the…[Read more]
Something interesting for Procaster users. Was on 1630 and didn’t like that I can’t be received on all radios/tuners so I tried 1500 and thought my range would suffer and sure enough the meter peak was less than before with the 3 meter exact length. So thought what will happen if I changed antenna length. Got the idea to cut exactly 10cm(4″) off…[Read more]
@ Artisan…maybe off topic but you mentioned your blog which I just saw for the first time.
Is there a provision to comment on any blogs?
There’s so many old radio shows like the detective ones, mysteries, original Gunsmoke series, Lucille Ball comedies before the I love Lucy TV show that have nothing offensive in it.
I think that it’s excessive…[Read more]
CHML from Hamilton here in Ontario still runs them from 10pm till 1am with original commercials too even with a Camels commercial that says doctors of all specialties recommend Camels to their patients and smokers that smoked Camels reported their throats felt much better! Seems to be doing OK in this day and age.
They are all from the 1930s 40s…[Read more]
Mark started the topic HERE'S MY NEW COVERAGE WITH NEWLY ACQUIRED PROCASTER ON 1630 in the forum General Discussion 3 months, 1 week ago
This is from indoor install with 3 meter wire and no ground.
Was using thicker 12 gauge wire and tried thinner wire 22 gauge and the thinner wire worked better to my surprise! Same exact position and meter peaked higher. Using studio for processing and Behringer 9 band EQ for tone control and laptop(Play it Live) for audio.
Thought of trying a…[Read more]
No, a coax is not the same as a length of wire. A coax is shielded with ground as shield and conductor in the center so it wouldn’t radiate.
You need a length of wire like speaker wire and the thicker gauge is better. You have to split the two parts for a single wire antenna. Or any stranded wire 12 or 14 gauge in a 3 meter length.
The Mosquito…[Read more]
What I can say is use the 75 ohm cable with the talking house as if you use that with the Mosquito it’s not matching the impedence it says to use and will degrade the signal and you will get more reflected power back to the transmitter. Go by the instructions and use a 3 meter wire with the Mosquito as stated.
Some of your questions are over and…[Read more]
Here’s a pic of the power supply you should be using. But in the correct voltage for the Talking House. This is just a sample picture I found. No need for extra transformer.
Notice the 3 prong connection. This grounds the transmitter. But this won’t cure your bad range problem. Most of these come compatable anywhere with 100-240 volts input.
If the switch is set to outdoor than the internal tuning should be bypassed. With the outdoor range extender operating change frequencies and watch transmitter and see if the internal tuning is operating by watching or listening.
As for the buzz a lot of these power supplies are garbage and the block style computer ones are the best and they…[Read more]
Well said, I am the same as you as I grew up with AM radio from the late 50s through the eighties.
It’s not just the local things in your house that are to blame but the power supply itself that’s dirty. That’s why there’s such a difference when using a portable on batteries or plugging it in.
Fortunately my AM station overpowers all this and is…[Read more]
Like this. Hope the finished product is certified in USA and Canada but I don’t see how this would be much different than the procaster for example. But good to have a new product on the market.
Just a few things to check. With the range extender is the internal tuning unit bypassed?
The range extender has it’s own tuning with a meter as I remember so if the internal tuning unit is also trying to tune the antenna it would maybe cause the poor range you are getting. Just s suggestion to check.
I know the newer “enchanced” versions have…[Read more]
It was me who had understood that the CM-10 had a Canadian version and a part 15 version as I remember being told, or so I thought that a component was added or removed when sent to a Canadian location. I had one and I found it had not to good range either and wondered if that was true. That one I had conked out as a shock was given to the antenna…[Read more]
The Talking Sign, not to be confused with the Talking House which you are thinking of was made in Canada by the same company that makes the Procaster before it was replaced by the current one you are using now.
