A lot of the gear is of commercial origin, stuff stations threw out, and I refurbished and repaired myself.

The left rack is the input rack, it contains the gear primarily concerned with feeding the console.  There are two valley 400 mic processors, their corresponding behringer effects units set up for light plate reverb, a mixer to combine the two dry feeds from the mic processors and feed the phone hybrid, a telos delta phone hybrid (nice because it has compression built in so I could eliminate the outboard compressor), and two phone preamps.

The console is an Audio Arts Air 2+ which kinda sucks because all the inputs are unbalanced, not a good thing in a high RF environment.  A nice console otherwise.

The right rack is the output rack, it contains gear primarily concerned with program conditioning tasks.  The top shelf contains a net top type computer running Linux and Zara with two audio outputs, one for beds/sound effects, and the other for log playback.  Below that is an Aphex compeller, which levels and peak limits the output of the console to protect the flash recorder and the STL (studio to transmitter link).  Below that is a broadcast tools switcher to control what gets fed to the flash recorder, and what feed is being monitored at the consoles external input.  In theory this would allow monitoring of up to 3 transmitters.  A flash recorder is fed by the switcher and used for airchecks.  There is then a Behringer format converter to convert the analog audio to AES which is then sent over coax to the transmitter.  The off air feed is brought back over coax and converted to analog to feed the switcher.  There is then a EQ to tailor the room characteristics to my club-foot nature, and a monitor amp to drive the speakers.

The monitors are a pair of Alesis MKII passive 6.5" monitors, mics are Shure SM-7B's

Everything is in road cases with connector plates and a detachable wiring harness to keep setup time to a minimum.

That's about it I think.

Yeah, you see I hate 'scoped' airchecks.  In most cases the music is the best part  ;D

0042 Tuned in to 6930KHz USB to hear the refrain 'Hallelujah, Hallelujah'
0043 brief pause, then much weaker ID 'LTO Radio ID's..ID's  Louisianna Texas Ohlahoma, this is LTO Radio', then off/QRT

About S9 on peaks here using the loop and the WR G331DDC

Thanks for the show!

Oy... And the record industry wonders why people steal music?

The RF Workbench / Re: Higher power design.
« on: January 13, 2016, 1326 UTC »
It is true, battery operation above a certain power level begins to get ridiculous, and that point seems to be 100W-250W.  Above that, generators or shore power are the logical choice.

The RF Workbench / Re: Higher power design.

I always like to look at the whole package, you never know what someone may try to hack up.

Just because it's in a rack doesn't necessarily mean it's indoors.  My TX lives in a road case and spends quite a bit of time with nothing but stars over it :)

Battery power is appealing if your operating from somewhere where you are not necessarily welcome, someone's field for instance, or back parts of a park.  Generator power in these instances, even with modern inverter type generators can raise the 'here I am' flag, as if a tall antenna didn't say it already.

Hmm, and they wonder why people steal music.  This is one of the reasons I'm happy to see the indie music movement gaining some traction over the last few years.  This level of stupidity has already forced the closure of some very good online stations, and the ban on listener interaction I think proved just how out of touch the recording industry is with the rest of the consumer base.

The problem with that is you still have the weight problem to contend with.  I like rack mount stuff, there's just something 'official' looking about it.  A relatively shallow 3U chassis could contain up to 1KW, and weigh less than 25 pounds.  At the 1KW level even considering modest efficiency, you still need around 1600W during 100% modulation, and that takes a rather heavy transformer.  Build a PFC boost circuit to get 250VDC, isolate the drive, and there you go.  I'd call that progress.  Leave the iron to the scrappers ;)

The RF Workbench / Studio gear used for X-FM's 2015 Halloween show
« on: January 13, 2016, 0048 UTC »
I won't publicly post pictures of transmitter gear, but studio stuff is usually innocent enough.  So with that a snap of the gear used last Halloween while the show was in progress.

Why not make the aircheck into a video....a few pictures of the audio equipment and transmitter etc popped on top of the audio and post to youtube.  

Someday when all this is in the history books and I'm out of the country (on a private island preferably) I will :)

For obvious reasons it's not a good idea to do that.  Besides, I thought DX'ers enjoyed the mystery of it

Kilo, do you still have issues if it's a 'private' post, ie one that will not show up in searches?

We'll try archive.org and see how it goes.  I put the January 2nd show up there.

And also the Halloween show with a bunch of callers.

There is some clause in the  web hosting TOS that prohibits web accounts from being used as a 'file repository' hence why it runs great for 30 seconds then times out.  FLAC aircheck run about 1.3 GB, MP3 ones around 300 MB.  I don't really know much about archive .org, outside of some recordings of us out there.  When putting something like this out there, the joys of copyright and fair use often get slung around.

General Radio Discussion / Aircheck hosting...anyone have any ideas?
« on: January 08, 2016, 1027 UTC »
I got the website fired up again thinking I would put some airchecks up there for people to download.  Turns out there is a limitation on file size, even though the hosting is unlimited bandwidth.

Someone mentioned using torrents for distribution, but then you need a seedbox somewhere which is more money (this thing doesn't create income, BTW).

I really don't want to run a webserver at the house for obvious reasons, but does anyone else have any suggestions.  Free is always nice, but I live in the real world too ;)
