optimizing audio to send to WBCQ

(1/3) > >>

PhreakinDeacon:
I have a general idea how to optimize audio in order to place it on, oh, say, an AM HF transmitter without fancy, real-time filtering or conditioning hardware between the audio player and the mic input, yet occupy the right bandwidth and sound decent . But now I am sending something for the first time to a licensed SW broadcaster, to play at WBCQ on their 50kW 7490 kHz transmitter.
They're very busy it seems (Allan Weiner has been gracious and swell, but I don't want to keep trying to bother him directly about any noob questions, aside from they will have to answer, "May I email you a download link, and is .WAV ok, if not how do you want it delivered and in what format?"
I'll call and find out because I haven't gotten an answer after asking a couple of times even in the PayPal notes, and it's always nice not to look too exceedingly stupid to people you saw as minor personal heroes for years, as I have him and his buds seeing them swashbuckling spectacularly on a converted, commercial fishing vessel. After watching a documentary on the unexpected tech nightmares filming Jaws was at sea for directors, I can only imagine being new pirating on the actual sea and watching your nest egg get shorted, salted, eaten up, beaten up, or confiscated.
Treating audio for WBCQ:
Since commercial SW seems to go with 10kHz bandwidth I guess I might as well:
Low Pass at 5kHz ? 
Even if they do this automatically, I might as well do it ahead of time and work within it so I can listen and adjust other EQ bands accordingly, more accurately knowing what to maybe boost to brighten up a dulcimer etc.
High Pass at, what... 60Hz? or maybe higher to ease up on bass energy? I do want to have some male DJ/MC umph but not be inefficient.
Maybe 90Hz?
And is it like Voiceover standards and limit peaks to -3dB or -3.2dB max(?)., or should I go a bit higher/louder/farther?
I have been doing voice track compression at like 2.5:1 or maybe 3:1
And music just whatever the least amount of compression brings every desired note up in RMS not too far from peaks nicely, but not overdone a.k.a. without the waveform looking overly chockablock (I heard they have good modulation on 7490, but I know, like, a ham Hallicrafters or something will start to saturate or not recover or something and actually not sound as good with too much crowded compression and not enough "valleys" or room...had this seemingly happen in the field, er, at sea 3.5 miles out).

And maybe boost mids, not as to sound aweful, but to get the most punch (seemed to increase my clarity and extend my discernible range in amateur free radio tests elsewhere).
But am I on the right track?
I know these are not the things to do for an FM commercial station, not only because they just run everything already thru their crunch compression, but of course the different mode is subject to different phenomenon.

Any help with these settings, or maybe "NO - they have equipment meant for that which will oversaturate pre-conditioned stuff with the same effects too much" would be of help. I can't get a phenomenal copy on that transmitter in the Gulf of Mexico, but on a good spurt of quality signal it doesn't sound like they're pumping a lot of EQ or compression or anything... sounds like really varied, occasionally very raw, optimized or muddy-sounding or distorted or under-normalized or under-compressed tapes some people send in for some shows, kinda, sometimes, in between other more beefy-sounding regular shows. But ultimately I don't know and that's why I'm here. Could just be my reception. I just want to send the best post-produced audio.
Thanks in advance.
PD

Pigmeat:
I talked to them about the very same subjects about a decade ago and got a big "Huh?" like they didn't know what I was talking about. They said they aired the shows the way they sounded when they came in.

It didn't make a damned bit of sense to me, but it's their radio station.

Stretchyman:
Yes, simple stuff. Limit the B/W 60-5K is fine, then compress and limit the audio. The actual format and level won't matter as they'll be able to play anything and adjust the level for optimum mod level.

I use soundforge, but any decent audio program will do. No meet to spend 1000's on a Neve or whatever...

PhreakinDeacon:
Much, much thanks, all, hehe.
I'm using the same ok/entry stuff I accumulated over the years, running Windows 7 since my sound module and software both don't all have Win 8 or 10 updates.
I have an Edirol UA-25 sound module, Samson C01 XLR-mic, and I have Cakewalk Sonar 8 Studio with soft synths to play with, but anymore I keep opening up Audacity to do simple stuff and find myself wasting way less time. Like to have music autoduck while I speak over it (for clarity) instead of staring at busses and considering before fader or after fader, fx send vs. bin, and idiosyncracies and uber settings galore, with Audacity I make two tracks and click Autoduck, LOL. It's not ASIO so you just can't audit effects real-time but the end result is as good (sometimes better for some reason).
Having fun... I thought getting on 50 or 100 kW was more expensive, and the Free Radio guys don't police what you play it seems. Maybe kind of like Public Access TV down here -- you do something wrong, you get in trouble, not the station. To a Point. But a pretty far Point. This girl I knew before I found God went on there and everyone was like...what am I looking at...that's when we figure out it was bubbles being blown with remarkable skill using her diaphragm, I guess. Needless to say the feed eventually got cut and there were riotous complaints and lots of elated teenagers, but besides the station being scolded for sleeping at the switch, it was the girl who had to get out on bond. They went and picked her up at her house like a week later.
I don't exactly have express copywrite permission from the late Winifred Atwell for her 50's piano jamming or Johnny Cash for his reading a couple bible verses, but I'm claiming fair use with critique and education. I don't think they'll mind.
Check it out, I read Genesis through a Cylon-style robot vocoder and I'll start with that. Not your average Christian show (just when you thought there was one too many, right... I was wishing there was more Mysteries of the Unknown Stranger than Fiction UFO/Bigfoot stuff myself even recently, but I had some really crazy stuff happen I'd like to share with you guys that made me reassess my lifelong pseudo Taoist agnostic paradigm. I'll try to make it interesting. Next 4 Thursdays 8-9PM EST (0000-0100 UTC) on 7490. The privilege would be all mine if you'd tune in.

Stretchyman:
Maybe you could play 'Dumb all over' from Frank Zappa's, 'You are what you is'.

Def worth a listen....
