Re: Offical AMC 8 Transition Thread (was Sat. AMC-8)

We had an MCI tower behind our dish giving us interference. Two solutions were tried: First, we put up a screen of hardware cloth behind the dish, which helped on many transponders. Hardware cloth (a Midwestern term) looks like heavy window screen material, made of metal--folks use it to keep rabbit...

Re: Offical AMC 8 Transition Thread (was Sat. AMC-8)

Old trick--if you have a spare LNB & either power out of S/A or can free up a receiver just to power it (with a T & DC block): Take the LNB & swing it around while looking at the S/A See if you see a signal. You may have something generating TI--but just on the transponder channel the Orbital receiv...

Re: Mutually Exclusiove Applications for AM Translators

In the last 250 mile window, one of the translators I sold went to Richmond, Va. On their first try, they were MX to another move-in. So we (buyer, my company and buyer's consulting engineer) quickly filed an amended application, which went through. The 250 mile window operated under the legal "fict...

Re: RM105 Desk

Soundcraft may also be using "auxiliary" feed in the sense of an "audition" feed.

Re: RM105 Desk

A quick glance at this console on-line...I suspect it may be hard wired this way. Most broadcast consoles provide an audition or auxiliary feed just for the purpose you describe--laying down a voice track while the main programing runs, or setting up the mix-minus feed to a hybrid. However, most req...

Re: Capacitors

It will cost you about $64 plus shipping for the two big electrolytics. The way they are mounted you can save a lot of grief just buying the right replacement rather than try to find a work-around. The remainder of the caps are all radials, and you'll probably have another $10~$15 total in those sma...

Re: XLR Mic switch or what ?

Given your dual usage--with several different users--I would look for a mike preamp that would allow the outputs to be sent to both consoles. Depends on the consoles. Some consoles are flexible on muting, and will mute on channels with high level inputs--so you can feed a high level output from the ...

Re: New Sound Board

I have installed 8 channel R-55E consoles at a number of stations. A high school 900 watt FM; a community college LPFM, and a 9000 watt college non-com. I have one in my production studio at one station. Cost is around $4,800 depending on modules chosen. The board comes with a 4 channel mike preamp,...

Re: Vertical or Circular polarization FM Broadcast

Unless you are streaming, you have next to no home listening. Go ask your friends what kind of table radio they use. So your audience is the car radio audience. Look at what passes for antennas on most cars. My company van--a 2005 Ford Econoline--has a vertical whip antenna. But my business partner'...

Re: More TV mergers coming soon.

Radio controls their means of distribution. Hop in your car and turn the radio on... TV is increasingly dependent on other carriers--cable and satellite. I haven't watched OTA TV for years..increasingly my prime-time TV watching includes programs straight from network servers via a download channel ...

Re: Offical AMC 8 Transition Thread (was Sat. AMC-8)

We bought one (used) like that to receive our state network on Galaxy at 99 degrees. Took the dish apart, assembled it on the new post aimed in the right direction, got "Derf" from the two way shop with his spectrum analyzer, & set it up. When we re-assembled the dish we left that actuator arm off. ...

Re: Looking for MusicGen installer

We use Natural Music which is a buy-out. Also in use at a college station and a high school station we help out. Like any such program, the real work is in deciding on categories, installing the database, and setting up a clock. Once this is done, the actual log generation is fairly simple, and data...
