Re: [Elecraft] help wiring a mic?

2018-07-10 Thread bill steffey

but for 18$,,, including the suspension
it looks  scool.


i bought a similiar if not identical... from banggood

it plugs right into the mic jack on the back of the k3 kx3  so 
much for 'studio'

Me thinks it is for computer video gamers and bloggers.

and it works just like every other electret

cut off the bottom response...

Hope this isn’t too far off the original topic.

Interesting. I only noticed “KOSS” when I was editing photos for a blog post. 
Mine must be a different production run. Here is the photo:

Has anyone here provided any information on how to wire XXX mic to a KX3?

We’ve all read various dissertations on how the mic is good/bad or just wrong 
for the use. 

I bought a similar mic from eBay and bought a cable from Radio Shack and a 
Behringer Phantom Power supply(cost more than the mic!). Had a Heil cable to 
use from Behringer unit to K3. Worked pretty well. Now use a PR77d on the K3S

You guys are all brutal!  :)

This is a hobby that we try things and see how they work and if it doesn't,
then you learned something.  Ham Radio is an experimental hobby or did we
all forget that.

All you audio engineers didn't get where you are today without going
through the school of hard knocks.Why not help him out so he can learn
something.  BTW, the KOSS SB40's are really bad.  All bottom end and little
highs.  Maybe the 2 I have are defective.

I have one of these mics and I use it for several uses, but I have also had
it on  my Flex and it sounds darn good and for the money while running
SmartSDR remote and using PC Audio.   I would recommend it for someone on a
budget.  I guess I'll have to wire it up for my KX2 and see how it works.
There might not be enough BIAS voltage as other had suggested.

Hi Ron,

Fear not, my spelling is quite different to US English. Never had a problem.

On another subject. KH1 was #331 mixed for me. I started from zero in 
mid 2000 after a spell of about 10 years QRT. The first 257 were with 
the K2. All have been worked K2/K3 and for the first three years only 
made about 500 QSO QRP to a low wire and less entities than is possible 
over a major contest weekend.


Now rather more tooled up!

Mike VP8NO

I feel Jim's choice of the term "poor" is correct, but in a monetary sense.

Yes, you may be able to get the mike to communications quality with racks of
audio processing equipment etc.,
but you will probably spend more for all that when you add the cost of the
mike, than radio costs by itself.

Seem a tad wasteful to me when the radio already has a good EQ and a mike
costing a fraction of the fancy "studio" mike will sound the same on the
other end of the QSO.

I don't under the fascination (or logic?) of using a wide response and
expensive microphone just to narrow it down to 300 to 2800 Hz, unless you're
H3LL bent on putting out a 10 kHz wide VOA grade signal that is frankly,
illegal anyway.

Yeah, yeah I know,  you're voice is "different" and you need all that stuff
to make it sound "right".
If that's what you want, then by all means go for it.
It's the same logic as using your (insert $200k car) to make daily commuter
runs mostly stuck in traffic.

Re: [Elecraft] help wiring a mic?

2018-07-06 Thread hawley, charles j jr
Good answer. A friend once petitioned the FCC to disallow AM. The answer he got 
from the FCC was that Amateur Radio was an experimental medium and as such, 
disallowing emission types was counterintuitive.

The word experimental tends to question some of the hard and fast rules that 
come up from time to time..

Sent: Friday, July 06, 2018 4:10 PM
To: elecraft@mailman.qth.net
Subject: Re: [Elecraft] help wiring a mic?

It depends on the emission type.  From 47CFR97.307:

"(a) No amateur station transmission shall occupy more bandwidth than
necessary for the information rate and emission type being transmitted,
in accordance with good amateur practice."

At 97.307, there follow numerous specific limits on spurious emissions,
limits on various forms of angle modulation, and an [in]famous symbol
rate limit of 300 on data emissions.  Thus:

If you're transmitting voice using AM, an occupied bandwidth of between
5 and 6 KHz would be compliant [nominal 0-2.5 KHz audio BW].  For SSB,
it would be roughly 2.5-3.0 KHz.  If you're transmitting CW, the
occupied bandwidth would need to be something around 0.1 KHz.  A data
transmission could occupy any BW so long as its symbol rate remains at
or below 300.

The rules are a little ambiguous as a result of the phrase, "for the
information rate and emission type being transmitted".  If ESSB is
considered to be an independent emission type, then it is compliant ...
it fills the BW it was intended to.  If it is considered to be a form of
standard, communications-quality SSB, then it may not totally compliant.

Re: [Elecraft] help wiring a mic?

2018-07-06 Thread Grant Youngman
Can we please not start the bandwidth discussion (er, wars?), yet again?

Perhaps it’s time to help the poor fellow wire his mic?  Which is all he asked. 
 Maybe we can’t do that.  Fine.  It’ll probably work out of the box.  And even 
if it doesn’t, it’s $20 … for goodness sake.  Cheaper than an Elecraft hand mic 
(which are perfectly good microphones, actually, and have no “plastic" sound to 
them that I’ve ever discerned).

Re: [Elecraft] help wiring a mic?

2018-07-06 Thread Fred Jensen

It depends on the emission type.  From 47CFR97.307:

"(a) No amateur station transmission shall occupy more bandwidth than 
necessary for the information rate and emission type being transmitted, 
in accordance with good amateur practice."


At 97.307, there follow numerous specific limits on spurious emissions, 
limits on various forms of angle modulation, and an [in]famous symbol 
rate limit of 300 on data emissions.  Thus:


If you're transmitting voice using AM, an occupied bandwidth of between 
5 and 6 KHz would be compliant [nominal 0-2.5 KHz audio BW].  For SSB, 
it would be roughly 2.5-3.0 KHz.  If you're transmitting CW, the 
occupied bandwidth would need to be something around 0.1 KHz.  A data 
transmission could occupy any BW so long as its symbol rate remains at 
or below 300.


The rules are a little ambiguous as a result of the phrase, "for the 
information rate and emission type being transmitted".  If ESSB is 
considered to be an independent emission type, then it is compliant ... 
it fills the BW it was intended to.  If it is considered to be a form of 
standard, communications-quality SSB, then it may not totally compliant.

Al, you are so right. I have been victimized by some of these folks in 
the past. I asked a question and was flamed on and off list.


My response was NOT a flame. Saving someone $400 dollars is FRIENDLY 
ADVICE, not criticism. I took the trouble to search for a data sheet for 
the mic, found nothing that would even tell me what connector was used, 
what powering configuration it had, or how the mic was wired.


Pro electret mics used a balanced form of powering called "phantom," and 
must work into a circuit that feeds + to both sides of a balanced output 
and negative to the shield. The electret mics used with unbalanced 
inputs get their bias in a very different way. The two systems are NOT 
compatible, and phantom power is built into preamps and mixers. W2IHY 
has built this into his 8-band equalizer. At $299, it's the lowest cost 
box I could find on his website that does it. AND -- if you have a K3, 
K3S, KX2, or KX3 there's a VERY good equalizer built in, so you're 
spending $299 plus shipping on the mic interface.


Bottom line -- with these radios, you don't need anything that W2IHY sells.

If you must use a pro (balanced) electret mic with ham gear, Radio 
Design Labs sells some relatively low cost mic preamps, but by the time 
you buy the preamp and the power supply(ies) you've spent some bucks 
there too.


http://www.rdlnet.com/search.php?searchquery=mic+preamp

But we don't know which powering interface the mic uses -- nothing I've 
found on the internet tells me. IF there is access to the capsule 
itself, it can be wired directly to the KX3 input.

Re: [Elecraft] help wiring a mic?

2018-07-06 Thread Wayne Burdick
Overall this is one of the most civilized ham forums out there, or so we’ve 
been told hundreds of times. 

But it’s easy for many of us to occasionally get defensive, testy, or even 
indignant when our long-held beliefs are challenged. Myself included. It 
doesn’t mean we're not sincerely trying to help.

The only way people on *any* list can get along is to be forgiving. We’ve all 
said things we wished we could take back. We feel even worse when things 
escalate for reasons having nothing to do with the original thread.

My advice:

If you’re turning red and slapping the keys hard when you respond to 
something--on this list, or anywhere else--wait a few minutes. Take a breath. 

Help us keep things fun and interesting here.

The poor guy who started this thread just wanted to know how to wire a mic. It 
quickly became a discussion of whether he should even use that mic. I don't 
believe we have that right. The question is about an XLR connector. We should 
either answer his question or lay out.

Very good sounding mics built into gaming headsets like the Yamaha CM500

I looked up this mic and tried to find specs. There's nothing there -- 
it's all silly putty.  Every place I looked said something different. 
:)  There's no response graph, not even a description of what connector 
is used and how it is wired!  Inside that mic is a cheap (maybe a buck) 
electret capsule. The shiny enclosure is simply designed to facilitate 
the separation process noted above.


I'm retired from a career in pro audio, A Fellow of the Audio 
Engineering Society, and have a closet full of REAL pro mics that I use 
for recording music. The only one I'd consider using (and have used) for 
ham radio is an RE16, a variable-D dynamic with a good blast filter.  I 
used it because, at the time, I didn't have anything better, because the 
variable-D construction eliminates the LF boost of proximity effect, 
and, because it's a dynamic, all I had to do was solder up a cable to a 
connector that mated with the rig.


List members K4TAX and W4TV are also retired broadcast engineers, and 
I'm sure there are others.

I feel Jim's choice of the term "poor" is correct, but in a monetary sense.

Yes, you may be able to get the mike to communications quality with racks of
audio processing equipment etc.,
but you will probably spend more for all that when you add the cost of the
mike, than radio costs by itself.

Seem a tad wasteful to me when the radio already has a good EQ and a mike
costing a fraction of the fancy "studio" mike will sound the same on the
other end of the QSO.

I don't under the fascination (or logic?) of using a wide response and
expensive microphone just to narrow it down to 300 to 2800 Hz, unless you're
H3LL bent on putting out a 10 kHz wide VOA grade signal that is frankly,
illegal anyway.

Yeah, yeah I know,  you're voice is "different" and you need all that stuff
to make it sound "right".
If that's what you want, then by all means go for it.
It's the same logic as using your (insert $200k car) to make daily commuter

Re: [Elecraft] help wiring a mic?

2018-07-06 Thread Sean Hayden
This is simply untrue Jim.  Many hams use xlr connected microphones with
phantom power.  A w2ihy iBox and a cheap behringer mixer will quickly
disprove your assertion.  I know of many hams that use such setups for
broadcast AM transmitters moved to amateur radio frequencies.

This mic is intended for studio and recording work. It is a very poor 
choice for ham radio.

If it is a condenser mic, it's going to need a 48v power supply  
They now make some nice little tiny ones...


I LOVE my condenser mic...

That mic appears to require 48 V phantom power (mic bias), which is far more

maybe not.

The manual for the Elecraft MH3 mic shows the wiring needed to work with the 
KX3.
