The radio station project involves playing stuff from a computer system.\u00a0 That requires a sound card.\u00a0 One of the better sound cards is the Delta series from M-Audio.\u00a0 They have been out of production for quite awhile but there is a regular flow on Ebay.<\/p>\n
The whole package consists of a rack-mount unit, a computer card and an interconnecting cable. Unfortunately, they usually don’t have the power supply.\u00a0 The one I bought didn’t come with a supply.\u00a0 The supply needs to produce 9V-AC at 4 Amps.\u00a0 So, I got back on the net and found a supplier, I think it was on Amazon.com and ordered one.\u00a0 It wasn’t cheap, I think about $35.\u00a0 And I’ve been using it.\u00a0 But it stinks.\u00a0 The thing is basically an overgrown wall-wart transformer with power in and power out cords.\u00a0\u00a0 Besides generally cheap construction mine makes a terrific humming noise that drives me nuts.<\/p>\n
So a couple of days ago I got online again and I ordered a 120V-9V toroidal transformer from DigiKey.\u00a0 With shipping it was over $40.\u00a0 But now I have the guts of a supply that will give the level of current required without howling like a dog on a full-moon night.<\/p>\n
I have a rack-mount AC power distribution box which was one of the parts of that mass spectrometer I scrapped out awhile ago.\u00a0 I’m converting it from 240 to 120 and I’m going to put the 9V-AC supply in there too.\u00a0 That will give me one power switch for the whole rack of radio stuff: computer, audio, transmitter, all of it.<\/p>\n","protected":false},"excerpt":{"rendered":"
