Microphone

w3pnm
I just completed assembly of my K3S, KAT500, KPA500 and P3. I didn't order a microphone from Elecraft. I am considering a Heil PR-10 but will welcome any suggestions.

Bill,

You could try a nice looking, computer headset with electret mic. You'll
be amazed by the results. The K3 works well with just about any mic.
Well done Elecraft.

I never bought any handmic. But I own several headsets, a $4,50 plastic
one (has a good mic), a Yamaha CM500 ($45, many K3 owners have that one,
good mic) and a david clark aviation headset (several hundreds of
dollars, good mic).

The difference is in the ears of the headsets, all mics perform well,
thanks to the EQ/gain/proc-setting possibilities in the K3. I take the
plastic headset with me when camping, the CM500 in my quiet shack and
the david clark when I'm working in a multi-operator contest with lots
op people walking and talking.

As far as mic-audio is concerned: how much hi-fi can you put through a
2.5kHz bandwidth SSB signal? Will the expensive Heil PR-10 make a real
difference? For peace of mind: buy the Heil. 'My mic is is Heil PR-10'
sounds quite different from "my mic is a cheap electret computermic'.

The CM500 is the clear winner -- great sounding mic, great sounding
headphones are very comfortable.  As a retired pro recording engineer, I
own several dozen excellent mics. Anything more expensive that the CM500
is a waste of money. The EV RE320 someone suggested is a nice mic for
broadcast work, but gross overkill for a ham station.

Re: Microphone

K2MAW
I’m still more of an audio professional than an accomplished ham, so I’ll ask while the thread is hot - why does ham gear use non-standard interconnects? Why don't Elecraft and others move to 3-pin XLR? Honestly, the bottom of my mic cabinet is probably overkill for ham, but the fact I have to get (or make) a custom adapter for even my least expensive mic irks me.

Bill,
 
I have the CM500, and am very, very happy with it. I also use a Heil Gold Elite that was originally on my ProIII. I use the CM500 way more than the Heil. The EQ functionality in the K3S is superb, making any inexpensive microphone sound like a million bucks. Don't go overboard on the $$ for a microphone. Put that extra $$ towards antennas!!

 > why does ham gear use non-standard interconnects?

Ham gear does not use "non-standard interconnects."  Nearly every
*communications* device ever made uses an unbalanced audio (mic)
input - whether is be the old tube gear with their high impedance
(think D-104 or Shure-444) mics or modern solid state gear with
the low impedance inputs.

Only broadcast and recording gear use balanced inputs with or without
high voltage phantom power for condenser mics.  Even general purpose
public address systems tend to use unbalanced mic connections.

Re: Microphone

alorona

The use of professional broadcasting and recording microphones is totally ridiculous overkill for ham radio application. On the air, these mics are indistinguishable from much cheaper units, if everything's adjusted properly. A ham who spends more than $75 on a mic because he feels he needs to to sound good is misinformed.
However, one factor at play here may be the pride of sitting behind a big name mic as you transmit. I'm not going to take that away from any ham who wants that experience. Just don't claim that it makes you *sound* any better. It doesn't.
R,
Al  W6LX

anyway do note that perusing Digikey & Mouser you will have a hard time finding
ANY electret from the worlds electret makers ,,, that exceeds
5$  ..(.5 for 3$ )
except knowles a chicago based mfg of tiny mic elements.
the cabinet /enclosure mic body, cable & windsreen add up ...
so make your own....  take an old mic  insert electret,,,,

WRONG -- virtually all modern PA and sound reinforcement systems have
used 3-pin XL connectors for more than 50 years. The exceptions are VERY
CHEAP junk sold by places like Radio Shack, and those built into
security systems. Most musical instrument amps have only unbalanced
inputs. Back in the '70s, I was maintaining lots of paging systems
professionally installed paging systems that used balanced mics and
balanced wiring exclusively, and many of them had been in service for 20
years. I don't remember ever working on a PA system that used unbalanced
mics except as lavalier mics connected to a wireless mic transmitter.

Communications mics made by companies like Shure, EV, and Turner
were/are made with output transformers that matched them to balanced
low-Z inputs for use in professional systems and unbalanced hi-Z for use
with ham radio, and PTT switches that can either be wired to key a
transmitter or short/open the audio path. The Shure 444 is a great
example -- the response is carefully tailored to roll off the low end
and add a strong peak around 3 kHz to compensate the rolloff of the TX
SSB filter. This response also works well for paging.

Re: Microphone

Hi Jim,

Gee Jim, I don't quite understand what your point is. You and I have always been agreeing that the use of professional audio microphones and other equipment for communications is not only a huge waste of money but also a big inconvenience; 3-pin XL is not a convenient connector for ham radio use. Who cares what PA and sound enforcement equipment equipment is using for a microphone connector.

Two very good reasons -- panel real estate and the lack of NEED for pro
mics.  optimum SSB bandwidth for communications is 500 Hz - 3 kHz. All
that low end does is suck TX power with no intelligibility gain.

Virtually any ubalanced electret capsule or dynamic mic works very well
with ham gear and sounds great. There is no need for pro mics with ham
gear, and they cost a lot more than commonly used ham mics that sound
quite good. All you need to run the electret is bias, which is applied
to the mic output, about 8V through about 6K. Neither value is critical.
This is exactly what we do for the lav capsules that are used with
wireless mics.

> Honestly, the bottom of my mic cabinet is probably overkill for ham, but the fact I have to get (or make) a custom adapter for even my least expensive mic irks me.

I was in the same position 12 years ago when I got back on the air, and
made a simple adapter to use an RE16 because I didn't own a ham mic. I
continued to use it (on an AKG boom stand) until W6XU found and promoted
the CM500.

Microphone

Elecraft mailing list
In fact, I find modern transceivers including K3 are very accommodating to microphones. Professional broadcasting microphone is simply over killed for ham purposes.  Sometimes, just a bit experiment, even with computer headset, you will get good results.
I sold all my Heil gears such as PR781.  I am now using CM500 and a few low cost mics.  I am not saying Heil is no good but too overkill for ham radio.

Two very good reasons -- panel real estate and the lack of NEED for pro
mics.  optimum SSB bandwidth for communications is 500 Hz - 3 kHz. All
that low end does is suck TX power with no intelligibility gain.

Virtually any ubalanced electret capsule or dynamic mic works very well
with ham gear and sounds great. There is no need for pro mics with ham
gear, and they cost a lot more than commonly used ham mics that sound
quite good. All you need to run the electret is bias, which is applied
to the mic output, about 8V through about 6K. Neither value is critical.
This is exactly what we do for the lav capsules that are used with
wireless mics.

I was in the same position 12 years ago when I got back on the air, and
made a simple adapter to use an RE16 because I didn't own a ham mic. I
continued to use it (on an AKG boom stand) until W6XU found and promoted
the CM500.

Not much. But there's more to microphone quality than frequency response.

1. Plosives. Will the mic handle poppy 'p' sounds without overloading?

2. Directionality. Is it directional? If not, you'll get more shack
reverberation, fan noise and reflections from the desk (causing comb
filter notches in the response).

3. Proximity effect. Will the mic increase LF as you get closer to it?
If it's directional, yes it will, unless it's one of the Electro-Voice
Variable-D types or similar. Omnis don't have proximity effect.

4. Handling noise. If hand-held, how much unwanted noise is generated as
you move around?

5. Screening. Is it adequately screened? If not, it may be more prone to
RF feedback.

Re: Microphone

Bill-3
The point is: Using most any mic - from $10.99 to $500.00 - because it
is all in the way you set up the K3(S).

Want a really super looking broadcast mic? Buy a $3 electret module and
build a mic case to suit your visual dreams. Plastic, PVC, wood, resin,
and IMAGINATION - and you rule!
