[AMRadio] Johnson Valiant Part Search
I'm looking for the white solid ceramic post (4 inch tall, 1/2 diameter, threaded holes in both ends) for my Johnson Valiant transmitter that serves as a connector post for the three 6146 plate parasitic suppressor leads. If anyone has one they would consider selling, please contact me at w0ng at comcast dot net with a "shipped" price. I'm kinda desperate and have had no luck finding one.

RE: [AMRadio] Audio Warble?
Steven, Thanks for the reply. It seems that I am getting this warble even with nothing on except the Phantom power on the VX-2000, and the EQ, UltraFlex and Compressor turned off. I even get it using a dynamic mic (Shure SM-57) instead of the condenser... I wonder if my VX-2000 is heading south? Bow W5EFR -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Stevan A. White Sent: Thursday, September 13, 2007 00:13 To: AM Radio Mail List Subject: Re: [AMRadio] Audio Warble? I listened to your audio clip. It really sounds to me like all your FX units are fighting each other to some degree. Example: I can tell you have a fair amount of de-essing set on your VX2000, you also have a good amount of high-mid and high EQ set on your PEQ-2200. This in itself creates a small amount of compression in those frequency ranges as they oppose each other in the different units. This also muddies up the sound as one unit tries to cancel the effects of the other. The complete opposite of what you wanted to achieve, no doubt. Then there's the matter of the EX-3200 AND the Alesis Compressor. They pretty much duplicate the stages included in your mic processor. I've been a broadcast engineer for more than half my life and I've set up a lot of audio processing for production studios, FM transmitters, and AM transmitters. The best way to set ANY processing is one step at a time. Follow the manufacturer's suggested starting points. I'm actually a Behringer fan and have used quite a bit of Behringer equipment. Most everyone that bad-mouths Behringer does it out of ignorance. They haven't read the book. Behringer stuff will do an outstanding job for you IF you read the book first. They made the stuff, they can sure tell you how to make it work. Same goes with anybody else's products. See what they say and then experiment on your own from there. So, follow the book's recommendations for basic setup and then spend a while fine-tuning each parameter. When you are satisfied with your mic proc, sparingly add one of the other units and play with it for a while. I'm betting you won't be able to improve things much over what you get with your mic proc since it is an "all-in-one" processor. The "warble" you mentioned is introduced early on in the mic proc. If you follow the book's recommendations and still get no satisfaction, yank it out altogether and use just your mixer and your compressor by themselves. It may be that the mic proc has a problem. Whatever you do, resist the urge to cascade the two sides of your stereo units. Also, the surround proc setting will be of no use since you're not processing a stereo signal. It will introduce some funky junk you won't like. Add stages only if they produce a desirable result. Otherwise leave them out altogether. Less IS more. Really! Let us know what you discover.

Usual disclaimers apply). If it's one of those mica look-alike wannabes, but really a wax-paber capacitor (typically vales .01uF and above), replace it with a mylar cap. -Larry/NE1S __ Our Main Website: http://www.amfone.net AMRadio mailing list List Rules (must read!): http://w5ami.net/amradiofaq.html List Home: http://mailman.qth.net/mailman/listinfo/amradio Help: http://mailman.qth.net/mmfaq.html Post: mailto:AMRadio@mailman.qth.net To unsubscribe, send an email to [EMAIL PROTECTED] with the word unsubscribe in the message body.

[AMRadio] Transmitting Mica F2 -vs- G2 types
I am getting ready to convert my Gates BC-1T to 75 and 160 and need some opinions on the loading cap. The 1T uses fixed capacitance and a variable inductor for loading. I need about 750 pF for the loading cap on 75 meters. The original loading caps (two in parallel) are G2 micas at 8000 vdc, however they are both 1500 pF. I have a type F2B that is 800 pF at 6000 vdc, that would be close enough, but I'm afraid it may not handle the current. The F2 is a much smaller unit than the G2's that are in there now. Anyone have any opinions on what the F2 can handle? Being on a higher freq. than original design I think the 6KV rating might be okay, but I'm still concerned with the current rating of the F2 as opposed to the type G2. Nebraska Surplus has what I'm looking for, but they want $175 for it.

RE: [AMRadio] Audio Warble?
Bow, I suggest that something early in the chain is generating a low-frequency oscillation, which is beating with your audio, particularly your lows, generating a form of intermodulation distortion. . Maybe something in the Behringer VX2000 Mic Preamp is either taking off, or maybe it's low-level 60 Hz hum?
