cliffyk,

Your explanation of how digital is being implemented on the FM band is different than how I imagined. Apparently the digital signals on AM is different as the bandwidth is 10 kc.

I am familiar with some other digital broadcast where the carrier width on frequency is from between 1.8 and 2 ...

I don't think HD radio is going to take off yet. Many people don't want to go out to buy a new radio just to get the digital channels. Even then the quality isn't all that great from what I've heard.

However your question was about whether anyone was using the HD radio equipment, and given the ...

Def as in broadcasting in HD or high definition (aka digital)? I would really like to know about switching over to HD and what additional equipment would be necessary? BTW, we have several local "HD" commercial stations already.

There are some passive (transformer) bal/unbal audio converters available at radio shack, but not cheap.
Good point, using balanced inputs had slipped my mind as hadn't been doing that while using my laptop...

Yes, I have balanced inputs on the transmitter and I think I have balanced inputs on ...

I normally use a laptop for handling my music but would like to give the laptop a rest. I have several extra servers sitting around that use on the board sound cards, the sound from these computers is/are very noisy...

Can anyone recommend a sound card that has a good S/N ratio that would be ...

So what's been going on, what kept you so busy all this time.
Well, my wife and I have been building our retirement house out in West Texas. It has taken us just about a year so far to get it where it is today.. I think I will be finished by May if I can find people to do the work. Construction ...

jbprptco,

To be honest that post was made last year, and I have been very busy since then. I don't remember which antenna I was talking about at the time. I think I was probably thinking about Verical Loops with a coil to reduce the size or EH antennas. Be sure to take a look at those antenna types ...

200-300 Km broadcast

I missed that one.

As for antennas, most standard broadcast stations use a multi bay Circular polarized setup. I will warn you, they are very expensive.

Do a google search on bkg77-hp and you will find one such antenna. There are many other models out there as well. Be sure to get an antennas that is rated for ...

87.8 Mhz is the lower end of the FM band here in the states, however, the FM audio for TV channel 6 is centered 87.75 (if I remember correctly). If you have a channel 6 OTA or on Cable in your area you will interfere.

Since I use Windows Media player (really don't like WinAmp), I wonder, are there any RDS units out there that work for me?

Sorry it has taken so long to get back to this post...

I have set it up so that the XLR board can be easily bypassed. Currently I am trying to get audio out of the stock board with no mods.

I have or have access to pretty much all there is in test equipment. BTW, I still would like to get a ...

I am having trouble with my AM Max II in that I now have no audio! How about a link to a schematic or send me on in my email?

Look at that regulator 7812. We usually take if from tap 3 of that
regulator.

Other than the power, I am ready to go. I don't have a picture showing where the 7812 regulator is and I don't see it on the PC board.. More info on the location of the 7812 regulator please?

PS. I haven't ...

BTW, When do you guys sleep?

Ok, a couple of questions.... Originally, this unit was to be shipped with the XLR board installed so one would assume that everything would be in there so I could easily mount the board inside the box and supply power to it.?

1. Is the unit is grounded through the stand-off and no ground wire is ...

There is also a coaxial cable for audio out?

And a red wire for positive supply +12v?

No, neither is installed or included.

Yes the XLR jack is already attached to PC board via three wires.
