I use a media player called foobar, free down load, it plays one song after then next no gap, with windows player ( Running XP for my radio compter) I set the crossover so the songs are pretyt much togehter or you can over lap too.I just use mine for around the house and that so not into a big production!
Thanks Mark, good advice, I am using the EQ on the windows media player I dont have any EQ on any window sound setting.
I will try 50 nano across the stock 47 nano farad cap, I was using 100 across it and also a 147 nano at one time. Each had its own pleasing sound but it got old after a while, I like bright well defined sound but the bass has to…[Read more]
I have been doing work on the TH 5 audio improvement phase.
Can anyone tell me just what the LM 358 does in the audio chain on the TH 5? I have been following some previous advice posted here on boosting the low end audio response of the TH 5. All good advice, however increasing C301 by 100 nano farads does greatly increase the low…[Read more]
Hi Paul, you make a very good point, I was assuming it had a 50 ohm output but i can see how I was wrong ! so easy to see it too when i gave it a look and reading your detailed explanation. Thank you so very much for letting me see my mistake. Never too old to learn! thank you for the excellent explanation, i do have a good scope, so ill see what…[Read more]
Hi Neil, good to hear from you,
On the hum problem, no not really, all I know if you pull the main breaker and run the transmitter on a battery you get a clear signal.
I read all the on line posts here and elsewere, when I researched the problem, and did a lot of experimenting.
I have an outside vertical antenna and one horizontal in the attic,…[Read more]
Hard work always pays off! Your doing a good job promoting our interests, so hats off to you from Radio Joe ! A lot of good points in your post and a good way to promote and gain interest for other new people with similar interests like ourselves. Good Job!
Hi Mark ,
Well I know my station(s) has at least has one listener…and like the song, “its 5 o’clock somewhere”, I am sure the possibility exists within a 1/4 mile of my antenna, there may be another listener out there somewhere also, if the noise level don’t eat the signal up before it leaves the house.Its nice to dream though.
Hello from Radio Joe,
On the subject:
All it would take is some politician to slip a modified part 15 document into some other huge complex bill dealing with dust in outer space or the like, and move it though the process in a day or so. Most of those guys don’t look at what there signing anyway, next thing you know we all hav…[Read more]
Hi Mark, thanks for the response,- the Jensen isolator looks great, but they list it at $200, but you know what, if a person has a real problem with hum and is concerned about frequency response, This one looks like the answer.
I didn’t do a wide search on price yet but im sure it can be had for less than $200
At least someone has come up wi…[Read more]
Radio Joe here,
I have been doing some work in the transmitter room and need to ask whoever may have some knowledge about the following subject.
I have from time to time used ground loop isolators between transmitters and audio sources such as a computer or VCR.
The reason for this is to eliminate hum and buzz which seems to…[Read more]
II put my Radio Shack transmitter module away up in the rafters, and I just connected my 8 track player amplifier output to the speaker in my collector tomb stone radio, that way I will have no problem meeting the part 15 rules and regulations- Thats the way I did it years ago so that’s the way I will end up doing it, put the tape player in a bo…[Read more]
Looks like I might as well go back to the days of my Lafayette AM broadcaster, you had to wrap the antenna wire from the broadcaster around the radio in order to get the signal. That should be safe to use that… Too bad the goofs who come out of Cuba or the islands some place who move to Florida think they can just go on the air to get their…[Read more]
I am going to try to improve the audio response of the TH 5- I know that in the past someone had posted instructions on how to do this, along with some photos and I think showing the caps that need to be changed on the TH 5 board. I have seen a few things on this but none have been very clear for example one post said to change these values…[Read more]
Need some information on how to change my logo when I post. I went into “members” and changed my picture there, it comes up each and every time I check my “profile” but when I make my posts it still shows the old “RADIO JOE” in red, logo… not sure what if I need to do something to make it show up on my posts or not.. Like I said it a…[Read more]
I listened to the improved IAM radio transmitter audio on the web link, sounded bit muffled to me, I don’t know, could been the bass boost they incorporated- I use an equalizer to kick up the bottom end on my TH transmitters, but most of the time I go back to the standard response the TH 5 gives me.
There is nothing I have built, tried, or us…[Read more]
I have two long wire ten foot antennas in the attic for two different AM broadcast band transmitters. I have one long wire ten foot antenna mounted outside of the house. Al l antennas are horizontal antennas.
The outside antenna is made from 12 gauge stranded wire and is only about 8 feet off the ground, maybe 9 in one part.…[Read more]
I thought the review was good, the person did a nice job of letting people know how things went. I thought the audio quality was good! the hum he talks about thats normal, I have it here on all my AM transmtters, has to do with house wiring and the rf mixing with line current in the house wiring. I might have t add this transmitter to my…[Read more]
