Re: [AMRadio] Microphone assistance
. I was thinking of a transformer in the microphone case and the 9 foot cord which goes against my grain. I know we can make any of them work. When I hear AM radio guys talk about HighZ I think of a D-104 and it's ilk at about 5 megohms, this is high Z! When I hear 30K ohms I am thinking of a Hi-Z SSB like Kenwood TS520s,Drakes and Collins. That is what they call high Z. Most broadcast mics, I think are about 50 ohms ( dynamic types). I notice that a Shure 515SB is rated at 150 ohms, actual is 170 ohms and is for use on 19 to 300 ohm inputs..I too like the mixer plan.. 73.. Mike - Original Message - From: "John E.

Re: [AMRadio] Microphone assistance
I read that a low-Z mic has a low source Z, but it wants to see a high load Z. The trick with a preamp is to present a high Z to the mike, but produce minmum noise with a low-Z source. But that's for perfectionists. A transformer will work fine. Capacitive loading at the hi-Z side will affect highs, even a few feet of coax is enough to be noticeable. So the transformer should be fairly close to the radio. Since the transformer inductance and the RF filrtering and cable capacitance will be shunting the mic, some resistive loading (10K, more or less) on the high-Z side might help the frequency response, at the expense of level. About two feet of shielded cable would allow the audio transformer to be a little bit removed from the power transformers, and might help keep hum out of it. I think Radio Shack carries audio transformers of this type.

RE: [AMRadio] Microphone assistance
You are correct Mike, One way to help with the cable capacitance trouble, if a XFMR is to be used to step up the voltage, is to put the XRMR close the input circuit or preferably in the speech amp chassis and incorporate a 3 pin XLR connector. Run balanced low Z from the microphone to the XLR input and using the shield of the cable for just a shield and not common the audio of the microphone. The mixer is a good plan if available and may have other uses. Mine also has compression using a Light Dependent Resistance device to regulate the audio level.

Re: [AMRadio] Microphone assistance
The trouble with low z microphones is that some times Once a Hi-Z mike sends it's signal out it needs a short low capacity cable to keep from effectively shorting the highs. Putting a transformer in the mike is ok as long as the cord is low capacity and short. The 9 foot cord sounds like a disaster waiting to happen. The reason, I thought, for the LowZ mics was so a long cable, 20, 30 40 50 feet would not suffer such troubles. The idea of a mixer and then the Z conversion sounds good.. Just another $0.02..

RE: [AMRadio] Microphone assistance
The trouble with low z microphones is that some times the output of the mic is too low and you don't have enough gain to get the modulation up high enough. If you do have enough gain then they work just fine in the hi-z input circuit. Beware that some input circuits do not have, or use, a coupling capacitor and the grid sets high above ground at 2.2 Meg or more, and develops contact bias. (no cathode bias resistor) The circuit works well with a ceramic or crystal microphone which has no continuity to ground but put a microphone which has continuity to ground such as a dynamic, even if it has a matching transformer, and it will kill the bias on the preamp causing the stage to operate in a distorted manner. If you don't want to go into the rig and modify the input circuit with a coupling cap then put one in the microphone to block the bias drain. The dynamic microphone will have a responds curve which extends much lower that the Xtal or ceramic so to balance it out you may want to do some extending of the high frequency range as well. You may also reduce the size of the coupling capacitor that you use at the input to limit the low frequency to a more expectable response for the rig.

Re: [AMRadio] Microphone assistance
The easiest way is to buy a transformer from some place like Guitar Center that does that very thing. You can usually find them in a variety of plug configurations nd they allow you to go from Hi Z to Lo Z or visa versa. Heil also sells a small transformer that will probably fit inside your mic that will do the same.

Re: [AMRadio] Re: Fraud
I turned a guy in the other day to QTH for using a call I knew was inactive. The guy gave his name and telephone number but it didn't match the call, who was last active on VHF in the 1960's.QTH kicked him off.If the guy had just used his name, with a phone number and said NONE for a call, I could live with that. But to use a call that is inactive is stupid. I DO research things before I buy from anybody.I think it is society in general that puts up with this kind of stuff. We amateurs have to hold ourselves to a higher standard.

Re: [AMRadio] Fraud on E-bay
As others have already said, he may just be lazy and grabbed your pics to save time. However, I would never buy from someone on eBay who has a 95.9% rating (4.1% of his transactions have negative feedback) and has hidden the feedback. There must be a reason he doesn't want you to read it. Since he doesn't accept Paypal you have no recourse if he cheats you. I will only send a money order to someone with a lot of feedback and a 100% positive feedback rating. 73, Clay W7CE Jim WB2FCN here.

Re: [AMRadio] Fraud on E-bay
Just my opinion but, this is probably more laziness and stupidity than fraud. $200+ is just not enough moola to attract the fraudsters. They will go for high 3 figures or low 4-figures all the time. I've been at the wrong end of 4 frauds so I am something of an expert. All were in the music or camera equipment area. I made the mistake of paying by money order the first time and lost my money. The post office did nothing even though I went through all their bureaucracy, worked with the local police as they recommended, etc. Lesson learned: Money orers protect the seller, not the buyer. The other 3 times were all by PayPal. In all 3 cases PayPal recovered my money. Two of them were for purchases just over $100 for which the seller just never sent the item. One seller even had the nerve to complain to me afterward about the bad feedback I left! The third one surprised me. I tried to buy a $2K plus audio mixer on eBay and PayPal would not let me send the money to the seller. They said the seller already had fraud claims against them. I researched the seller (because it was quite a bargain--in retrospect probably "too good to be true") and sure enough, e-mails bounced and phone calls went nowhere. I was on my knees thanking PayPal over tha one. This guy just looks like someone who doesn't know what he is doing and is trying to remain anonymous. Just an idiot, probably not a fraudster, IMHO. He probably found the pic in a google search and that saved him from having to take one. 73, Don Merz, N3RHT --- Jim Candela <[EMAIL PROTECTED]> wrote: > Jim, > > There is an interesting disclaimer at the bottom > of the auction: > > > "NOTE: Pictures shown are reproduced from the > Motorla web site, and not of the actual item" > > I never knew Motorola made an HT-32! :-) > > Regards, > Jim > JKO > > > > > __ > AMRadio mailing list > List Home: > http://mailman.qth.net/mailman/listinfo/amradio > Partner Website: http://www.amfone.net > Help: http://mailman.qth.net/mmfaq.html > Post: mailto:AMRadio@mailman.qth.net > __ AMRadio mailing list List Home: http://mailman.qth.net/mailman/listinfo/amradio Partner Website: http://www.amfone.net Help: http://mailman.qth.net/mmfaq.html Post: mailto:AMRadio@mailman.qth.net
