mic

Hi I am a new owner of a K3 and I am curious what others are using for mics? A boom mic is my is my preference as opposed to a headset arrangement. Any info appreciated.

73,
Steve W1DXH

Re: mic

Customized large capsule condenser mic on a Heil PL2T boom using ONYX
Blackjack for power supply/control.

Everyone pissed and moaned that it wouldn't work, was too much trouble,
overkill, yadda , yadda, blah.

Love it! At least 15 people have offered to buy it from me for twice
what I have in it. Response curve it "tilted" a bit towards use as a
radio mic, but still useful for audio tracks, videos, et al. as well.

Works for me as nothing is ON my desk anymore but my keyboard and
mouse. (See my QRZ page for more info and/or email me).

Re: mic

Personally I prefer the headset, have several. I do not sit still enough
for a boom. My mike is always right in front of my face where it needs to
be and I need the earphones to hear properly anyway.

Re: mic

In reply to this post by Clay Autery

Tried both condenser and dynamic. I have settled on the dynamic (mxl bcd-1) as it picks up a lot less background sounds. The condensers work very well but even pick up my wife talking the the dog downstairs! I do use a noise gate and preamp.

Re: mic

In reply to this post by Jim Rhodes-2

Yes, sir... I get that. I'm an old Infantryman/Aviator... almost a
requirement for me to have GOOD headphones and properly tuned receive audio.

Someday I'll demo the high end headsets and see if it is anything I want
to do.... I wore a CVC helmet for years with a boom mic with a lip
switch... (long time ago). Not sure I want to do the headset again. My
Sennheiser HD598SE head phones are about as heavy as I want to go
without custom fitting and contouring pads on the ears and head strap.
And if I'm gonna be on a headset, I want a mic switch on it AND I want
it wireless. :)

Re: mic

In reply to this post by bdenley

Well, it DOES take some fiddling to get it all the way it needs to be.
First thing is to make sure it is set for Cardoid and not OMNI... The
ONYX Blackjack gives me a little control as a pre, but I find that based
on the parts and construction mods I made, I don't have extraneous noise
pickup.

73,

PS - My mic is built on the housing and chassis of an MXL-990 that was
stripped and powder coated black. THEN, I also back-filled the ENTIRE
lower chassis to eliminate voids. Then added internal sound/vibration
absorption. And a proper basket.
I could probably sell 10 of them a month if I was so inclined. I am
not! It was a LOT of work to do it PERFECTLY.

Re: mic

Clay:
What condenser capsule did you put in the 990 housing. Just curious. I am using the Behringer Shark DSP 110 as a preamp, low cut, and noise gate. You can find them used for about $50. Turn off phantom power with the dynamic mic. I use the same setup with condensers - just turn on the phantom power.

Sorry, but you guys are WAY over the edge on this. As a retired
recording engineer, I own a bunch of great large and small diaphragm
mics, both condensers and dynamics, that put these mics to shame, but I
wouldn't waste any of them in a ham station. I'm VERY happy with a
Yamaha CM500 since W6XU turned me on to it around 2009, at a fraction of
the cost. It's plugged straight into the rear panel mic jack of my K3s
(plural, not the new K3S). Any decent electret will work as well,
especially with the EQ built into a K3, K3S, KX3, KX2. Those large
diaphragm mics are great for when I'm recording a symphony orchestra or
a great jazz big band, but they are a waste in the ham shack.

73, Jim K9YC

Re: mic

Agreed Jim but I haven't spent much money on any of the mic stuff and I also used a cheap ($40) headset rather frequently. I do, however, prefer the dynamic mics. The condensers that I have tried seem to pick up way too much background noise.

Re: mic

In reply to this post by Jim Brown-10

On Jim's points, I fully agree. It seems hams are prone to over
complicate a rather simple issue. There's more than adequate mike gain
in the K3S, thus I find no technical reason for the use of an external
preamp. The internal EQ of the K3S again is most adequate to correctly
tailor communications audio, even ESSB.

I've found mike technique to be a very important factor in good quality
audio. From personal observations, many hams have and use poor mike
technique. The mike-to-mouth position is most critical and will vary
with different mikes.

Like Jim, I'm a retired recording studio engineer and a live stage
performance engineer. Nothing but experience and learning from the
experts will improve what you do.

Re: mic

Bob and Jim have excellent points.

There is one advantage for the electret mic compared to a dynamic
mic. Electrets are generally 26 dB "hotter" than a dynamic mic
and thus are much more resistant to common mode RF feedback and
magnetic coupling. However, that assumes the transceiver is
designed for the higher input level and properly reduces gain
before the mic gain control.

Mics of any kind - dynamic or condenser/electret - with wide frequency
response are completely wasted for amateur radio (or any communications
application). You really want a clean 200 Hz - 4 Hz response. Lower
frequencies cause distortion and waste power, higher frequencies are
simply lost in the "channel noise".

Like Bob and Jim, I spent my professional life in the recording and
broadcast industries. Amateurs waste far too much on over spec'd
microphones and fancy "brand name" advertising campaigns.

Re: mic

Jim, we've already had this discussion. <smile>

Man asked me what I was running, and I told him. I like it. It's a
wonderful mic. It does the job..... well!
I like nice things. Not like I'm trying to use it on a DXpedition. <wink>

I find pleasure in having, using, and BUILDING nice things. It's not
about the money or doing the job.... If I wanted that, I'd still be
working a J-O-B.

As my Mamaw used to say, "Clay, that's why they make different flavors
of ice cream."

Have a great day! <big smile>

Well, in my admittedly inferior level of "studio engineering" skills and
experience, I must be the proverbial "blind hog", because I seemed to
have "accidentally" "tripped across" a combination and setup that does
the job well. <just a little bit of snark... grin>

As I told Jim, today and the last time we had this discussion. Man
asked me what I run, and I told him.
For some folks, it's not just about doing it cheaply, not about doing it
efficiently, etc, etc...
Everyone has their own reasons why they do what they do.
I "built" and customized this mic because I wanted to do it. It was
FUN, and that's why I use my increasingly limited time on this earth in
amateur radio. To have fun. <big smile>

It was an excellent academic and skills exercise, too. And one simply
cannot argue with the results. No less than 15 people have offered to
buy the setup sight unseen.

But, don't despair... I still read everything you smart guys write, and
I use every little tidbit I can. I've done my best to surround myself
with smart folks all my life.

e.g. in this instance, I used Jim's recommendations as a starting point
to set up the TX EQ on the K3s... THANK YOU, Jim! <smile>

73 and have a wonderful Sunday!

PS - When the mic project started, I was ALSO building a small studio
setup to do voice-over work. <wink>

Hi Gang:

I'll add my agreement with what other professionals have said. And, I'm a retired Technical Supervisor for Audio and Post Production at CBS-TV. We had a ton of really good microphones at our disposal. But I use the MH3 with my KX3 for those rare times I use a voice mode. Most of the time, I operate CW. :) If I did more voice operating, I'd get that Yamaha headset/mic combo.

Re: mic

In reply to this post by Joe Subich, W4TV-4

See my earlier responses to both gentlemen. <smile>

1) Frequency response.... yep, understand and agree. One of the things
I learned from one of Jim's papers as a matter of fact. Which is why I
modified the mic design slightly to produce a frequency response curve
more suited to amateur radio and as clean as I could possibly make it
within my resources. Thanks, Jim.
2) Also why I use Jim's recommendations for TX EQ on the K3s as a
starting place to NOT waste power. Thanks again, Jim!

I don't consider it EVER a "waste" when I 1) learn new stuff, and 2)
have fun... which of of course my primary motivation for doing ANY of
this in the first place.
And the "brand name" on my microphone is "Autery" or "KY5G". <wink>

Have a super Sunday!!

I find pleasure in having, using, and BUILDING nice things. It's not
about the money or doing the job.... If I wanted that, I'd still be
working a J-O-B.

As my Mamaw used to say, "Clay, that's why they make different flavors
of ice cream."

Have a great day! <big smile>

73,

I actually need the preamp with some mics, especially the dynamics I don't have a K3. My K2 doesn't have much mic gain. My other rigs do.

There's more than adequate mike gain in the K3S, thus I find no technical reason for the use of an external preamp. The internal EQ of the K3S again is most adequate to correctly tailor communications audio, even ESSB.

As a retired recording engineer, I own a bunch of great large and small diaphragm mics, both condensers and dynamics, that put these mics to shame, but I wouldn't waste any of them in a ham station. I'm VERY happy with a Yamaha CM500 since W6XU turned me on to it around 2009, at a fraction of the cost. It's plugged straight into the rear panel mic jack of my K3s (plural, not the new K3S). Any decent electret will work as well, especially with the EQ built into a K3, K3S, KX3, KX2. Those large diaphragm mics are great for when I'm recording a symphony orchestra or a great jazz big band, but they are a waste in the ham shack.

Yes, that's a known issue. MANY years ago I worked out a simple mod for
the K2 to add 6-8 dB of gain for a dynamic mic and add some LF rolloff.
I think W3FPR has notes on it. There are other mods further along the
signal chain, but they are not as simple.

Although headsets like my Heil Pro 7 may be more money, am I really "wasting" money on buying a "fancy brand name" considering the unit consists of mic and incredible speakers? It is a complete package. Besides the amazing electret mic, the sound from the headphones helps me to enjoy the hobby more and allows me to pick out signals I would not be able to without them. I don't think you meant to, but your post came off as if we bought some snake oil.
