Re: Unplayable audio files

Are those the original files, or did someone attempt to "help out" and incorrectly convert the native file fomat to WAV before giving you the disk?

Re: SEARCHING FOR CAPS

Bob, if a 2100 VAC cap will work, it's as close as your nearest microwave oven (or appliance parts store). 0.9/2100 is a standard size.

Re: Quiet UPS

We operate 13 APC SmartUPS 1500s and none of them make a peep. Only noise I've ever heard is a quiet clunk when they test themselves once a week. 5 of them are in studios. That's what I have in several studios as well. Haven't really had any issues with then and they seem to tolerate the 1960's mec...

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

So, Is a Scientific Atlanta model 9000 2.8m solid dish 2 degree compliant? I don't believe it is. Sure did put a lot of those in about 25-30 years ago, they held up quite well but they're just too small. Is this the dish that has a screwdriver adjustment of the polarization out on the outside edge ...

Re: Reviving a dormant antenna system

I agree that Mark is giving the best advice engineering wise. But money wise and who isn't these days why not pressure it up, load into it and see what happens. You won't waste that much time testing it, maybe will still work. That is almost certainly what is going to happen. The thinking (in gener...

Re: Engineers office computers

My "office" computer is a laptop and the covers are not missing. :lol: I do have a test mule PC back on the workbench with no covers, it's used for testing parts, copying drives and other similar tasks. Lewis, I know what you mean. I think I can still build a Scott SS32 blindfolded. Lost track of ho...

Re: snow/ice prevention

Glad you asked! Got one dish with no cover. It hasn't failed at all. Got another with the big plastic/rubber cover. Had to go there twice in a week to beat the crap outta the membrane with my crutch. Actually worked pretty good until I discovered my pant leg was snagged on the top of my suede winte...

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

I'd also be interested to learn what others are using (if anything) for snow/ice prevention, particularly for dishes that are not easily accessible.

Re: Possessed Barix 500 Reboots Itself

One thought regarding changing out the power supply on the Barix 500. If in fact that is the issue due to lets say a toasty summer day would a faulty or damaged supply explain that it reboots at the same time everyday? Possibly. If the filtering in the supply has become marginal, one possibility is...

Re: Possessed Barix 500 Reboots Itself

Try swapping the power supply with a different Barix and see if the problem follows.

Re: Production Studio Soundcard

If you are looking for balanced audio, there isn't much in the mid-price territory. A few USB offerings from Focusrite, like the Scarlett, or internal USB cards like ESI's Julia. Both about $200. The Julia is probably the cheapest way to get +4 balanced audio. http://www.esi-audio.com/products/julia/

Re: FM Composite isolation

We used 111-C repeat coils for many years to isolate those newfangled Optimods from old Collins exciters. Worked fine. The larger issue in my mind is the capacitance of the cable between your composite source and exciter input. It will roll off high frequencies first, starting with your stereo separ...
