 There were some microphones produced for the communications market back

 lower frequencies and somewhat faster at higher frequencies. That hump
 helped with articulation by emphasizing the mid-range speech frequencies.

This is a presence peak.

 I don't know if anyone is doing that today for mainstream communications
 microphones.

Today Paging Microphones are still specifically designed to have this
pronounced mid range presence peak and also usually include Quite a bit
of low frequency Roll off 

Shure have a range of dynamic elements available for this market, that
have response curves that look remarkably similar to the HC4 and HC5

elements for these mics (and many others) are available at low cost as
replacement parts. 

Heil sound plot their curves on a different log scale but after
accounting for that the similarities are remarkable.

The needs of paging systems which include efficient use of limited power
and maximum intelligibility in noisy environments are pretty much
identical to our requirements for effective SSB modulation. Any well
made paging/ Dispatch mic (or element..) is ideal for amateur radio use,
most are far more durable and cost effective than 'the made for ham
radio' stuff that is popular these days.  

  Even the high end Ham mics only offer general and
 uninformative comments about shaping and clarity that say much and
 convey little.

These words (in ham radio use anyway) have become marketing speak and
now mean nothing. As a former audio professional I cannot understand why
all the hype about Audio in ham radio and to my ears there's a lot of
money wasted on trying to make SSB into something it isn't.
  
  Interestingly, one of the big exceptions is the inexpensive
 little Radio Shack electret element. It comes with a frequency response
 chart showing a very flat response across the audio spectrum.

If you are looking for flat then these are a great place to start,
however the design of the housing may have quite an impact on how things
sound, this can be used to your advantage to create a presence peak or
LF roll off.

My own headset is based on a salvaged electret condenser mic with some
audio tailoring done by means of a simple R/C filter, being lazy I
copied the circuit of an Icom handmic. It works great and cost me almost
nothing.

Re: [Elecraft] K3 Convergence

2008-02-14 Thread Simon Brown (HB9DRV)

Taking things a step further - it would not be at all difficult to allow
other programs to send K3 commands to / from the K3 through another program.

This program (server) controls the serial comms and supports an unlimited
number of clients. The clients speak to the radio using the radio's native
protocol through the server.

It's a simple concept, the programming is not too difficult except when
talking with some of the older Yaesu radios. Supporting the K3 / Kenwood /
ICOM like this would be simple.

As for things like split mode - as far as I can remember no ICOM radio
supports this via CAT commands, not even the $10k+ IC-7800 :-(

No, every program needs to know the radio status at all times.
If one program changes a setting that a second program relies
on without notification, nasty things can happen.

Re: [Elecraft] Microphones (was electronic product standards)

2008-02-14 Thread Geoffrey Mackenzie-Kennedy

Thanks for posting your interesting comments Brendan.

Within the context of SSB useage in ham radio I believe that the 'hype about 
audio' could lead to another related problem, if not already existing, which 
is poor use of the HF spectrum available to us. Given the proven fact that a 
SSB transmitter filter bandwidth of 2.1 kHz will result in the transmission 
of a very 'good quality' speech signal, provided that the carrier is 
positioned properly and that the mic - audio - modulator system 
characteristics suit human speech, I see no valid reason for using wider SSB 
filters. In addition to the increased amount of spectrum used, the use of 
wider filters followed by linear amplifiers whose IMD products might be only 
30db or so below a test tone obviously results in a wider 'Interference 
Bandwidth', and should be discouraged IMHO. Adding Reverse ALC to the mix 
can further increase interference.


Just an opinion.

I have tried several mics with my K2 and the best reports are from an old

 What is all the noise about microphone compatibility?  We are radio 
 amateurs, it should be simple enough to wire a microphone for a rig.  
 Just look at the pin outs on the mic and the rig and wire accordingly.  
 The circuitry is not exactly complex!
 If we buy *any* radio we pretty much know that the mic wiring is going 
 to be different.  4-way, 8-way, RJ45 connectors, the list goes on.  What 
 ever the manufacturer decides is the right way for them, this has always 
 been the case.
 It really is quite simple.  Is your microphone a dynamic type?  If so, 
 wire it for Kenwood and it will work.  Does it need a voltage?  Look at 
 the diagrams as I mentioned before.  Good grief!  Elecraft are building 
 the rigs for us now and we are still moaning! ;)

Re: [Elecraft] K3 Convergence

2008-02-14 Thread Barry N1EU

Yes, Simon is describing what I had in mind - a software solution that can be
implemented in the near future.  Lacking such an RS-232 server program,
we're left only able to run one CAT-capable program at a time.  Unless your
contest logging program implements its own version of cw skimmer or
clickable panadapter etc, we won't have these capabilities unless software
that will arbitrate access to the serial port from multiple programs is
available.

[Elecraft] VP6DX on 160 Elecraft Mojo

2008-02-14 Thread Julius Fazekas
Worked VP6DX this morning on 160...

I was running my K2/100 (about 90 watts to the tuner
due to some foldback issues) thru the KAT100 into a
55' piece o' wire with a few radials, none any longer
than 40'. It was a solid no repeat QSO.

Those folks have good ears and they were a solid copy
without a Rx antenna on the K2.

Don't be afraid to try them, even if you think your
antennas are lacking.

Worked them on 12M CW as well, been ages since I even
heard anyone on 12!

GL to all in ARRL DX this weekend. It's looking like a
Low Band show.

I've heard it said that some contest stations deliberately transmit   
a wider-than-necessary signal to keep competitiors away from   
their channel.


I personally would not intentionally transmit a wide signal during a  
contest. It would, imho, be counterproductive, apart from any other  
reasons.


On the small 40m band in Europe, during large contests, you almost can  
not avoid stations sitting on top of each other and/or overlapping.  
Even if I assume that there were no BC stations between 7100kHz and  
7200kHz and that a channel is only 2.5kHz wide, between 7040kHz and  
7200kHz one only has space for 63 running stations without any  
conflicts arising, or using the older limits of 7040kHz to 7100kHz  
space for 23 SSB signals. Here there will always be a certain amount  
of elbowing going on. If one considers all the high powered phase  
noise being radiated and so on, then even a 9+20 signal can be a weak  
signal when compared to 40m contest noise levels. And finding gaps  
between stations can be a real art.


This is why you want to have a signal with a very high average power  
level, but one which is also not wider than necessary.

I know that there has been lots of responses to the microphone compatibility on 
this forum but let me comment on this subject on a different light.

When I first became licensed back in 1957 we were expected to, at the very 
least, be able to read and interpret schematics, wire up our own rig 
interconnections, and in a lot of cases build our own equipment.
Now days that is not necessarily true for quite a few of our fellow radio 
amateurs. 

Because of the above, it can be quite a challenge for some of us to perform the 
necessary research and rewire our mike connectors for the Elecraft K2/K3 rigs.

Many of us would have no problem doing this but we can easily forget that there 
are those who are dependent on getting the correct mike for the rig or have 
help in changing their connector's wiring to match a rig.

Manufactures are little help as they wire their mic jacks to what pleases them 
and it is their right to do so.

The bottom line is lets help those who need it and not criticize them. and for

Re: [Elecraft] Decode 1 signal only

2008-02-14 Thread Greg - AB7R
I havn't used it yet.  But it seems to work on the audio output from the radio. 
 If 
that's the case it seems it would only decode signals that are in your RX 
filter BW.  
Isolating the signal you want and narrowing down the filter should give you 
what you 
are looking forI think.  :)

Re: [Elecraft] K1: Inp Menu Item Pdn Only Allows Dits

2008-02-14 Thread Don Wilhelm
I can guess at 2 possibilities - one is that there was something sticky 
on the shell of that mono plug which adhered to the wiper in the paddle 
jack - it only takes a bit of something like the adhesive from 
electrical tape to do that. 

The second is that somewhere along the dash signal line, you have a bad 
solder connection that made contact when it was touched.  If you have 
trouble again, I suggest checking the schematic for everything connected 
to the dash signal (including connectors) and re-flow the solder.

Ty,

I have not tried an electret element, but I have a Heil HC-5 element in 
my D-104 frame that I have been quite pleased with.  I made my own 
'filling' for the much smaller sized element, but Heilsound does sell a 
kit for just that purpose.


Just use connectors for the AF and PTT that mate with the K3 rear 
connectors and you should be all set.  I recommend shielded wire all the 
way for the AF and AF ground wires.

[Elecraft] CW with my new k3

K3/KPA #241 is operational. When transmitting cw, if VOX is active it works, if 
VOX and QSK are active it works, but if QSK is active without VOX it keys but 
no indication of power out. The Op Manual seems to say VOX must be on, but I 
thought with qsk VOX would not be necessary (semantics?). If someone can 
confirm this to be the case, I would appreciate it.

Re: [Elecraft] CW with my new k3

2008-02-14 Thread W6NEK

Hi Joe,
Your K3 is working normally.  When in CW mode you must have VOX turned ON to 
enable CW output power while keying regardless if QSK is selected or not. 
In this case, while in CW mode, it is semantics.  On my 7800 Icom makes a 
distinction.  When in SSB mode it's called VOX and in CW mode it's called 
BK-IN (Break-in).


There's nothing wrong with your K3,

[Elecraft] Not All Hams are Technicians (WAS: Microphones)

2008-02-14 Thread Ron D'Eau Claire
Agreed Dave! Hams are not necessarily electronics technicians or engineers.
Many simply want to operate with what they feel is the best commercial gear
their budget will allow. 

They are just as much Amateur Radio Operators as the guy who designs his own
rigs from scratch. 

We've always had that disparity among Hams. Decades ago, before
radiosporting was popular, those operators were largely traffic-handlers
in the days when a telephone call to a city 100 miles away was both
expensive and difficult. Hams offered an excellent way for people to pass
non-critical messages quickly and efficiently for free and usually much
faster than the post. 

You can go all the way back to the days of spark and find ready-made
equipment for those who do not want to build their own gear. They've always
been an important part of the hobby. When I got on the air, there were hams
with fully factory-built stations from time-honored manufacturers like
Hallicrafters, E.F. Johnson, Collins, National, Millen and many others.
There were microphones like the venerable D-104 and dozens of others that
plugged into the rigs for phone and keys that plugged into the rigs for CW. 

And, back in the 1950's, some homebrewers were pretty arrogant about the
'appliance operators' on the bands who couldn't read a schematic or build
their own gear. Some things never change, Hi! 

Being able to pass a test for the license and the competency and confidence
that comes from actual hand's-on experience are two entirely different
things. Those who pass the test might not wish to tackle actually putting
that information to work in their shacks. 

The challenge comes with those who have the interest and are still
developing that experience while learning. Every technician and engineer
today has passed through that period, whether they are amateurs or
professionals. A key part of Ham radio has always been for those who can to
help. It's what this reflector is all about. It's what companies like
Elecraft are all about, providing kits for those who want to build but who
lack the knowledge, time and equipment to do their own design work; kits for
fully-functional rigs to simple test equipment to help them built up their
shop. 

We might be seeing a slight shift in the membership here now that Elecraft
is providing factory built rigs, but that's been the case of other famous
Ham rig manufacturers like E.F. Johnson. All it means is that Elecraft is
addressing more of the Ham community with their products. 

For someone wanting an off-the-shelf microphone, Elecraft provides one for
their rigs. Perfect plug 'n play. 

Ron AC7AC


-Original Message-

I know that there has been lots of responses to the microphone compatibility
on this forum but let me comment on this subject on a different light.

When I first became licensed back in 1957 we were expected to, at the very
least, be able to read and interpret schematics, wire up our own rig
interconnections, and in a lot of cases build our own equipment. Now days
that is not necessarily true for quite a few of our fellow radio amateurs. 

Because of the above, it can be quite a challenge for some of us to perform
the necessary research and rewire our mike connectors for the Elecraft K2/K3
rigs.

Many of us would have no problem doing this but we can easily forget that
there are those who are dependent on getting the correct mike for the rig or
have help in changing their connector's wiring to match a rig.

Manufactures are little help as they wire their mic jacks to what pleases
them and it is their right to do so.

The bottom line is lets help those who need it and not criticize them. and
for those who need help get it here or ask a fellow ham.

 I've heard it said that some contest stations deliberately transmit   
 a wider-than-necessary signal to keep competitiors away from   
 their channel.

I personally would not intentionally transmit a wide signal during a  
contest. It would, imho, be counterproductive, apart from any other  
reasons.

On the small 40m band in Europe, during large contests, you almost can  
not avoid stations sitting on top of each other and/or overlapping.  
Even if I assume that there were no BC stations between 7100kHz and  
7200kHz and that a channel is only 2.5kHz wide, between 7040kHz and  
7200kHz one only has space for 63 running stations without any  
conflicts arising, or using the older limits of 7040kHz to 7100kHz  
space for 23 SSB signals. Here there will always be a certain amount  
of elbowing going on. If one considers all the high powered phase  
noise being radiated and so on, then even a 9+20 signal can be a weak  
signal when compared to 40m contest noise levels. And finding gaps  
between stations can be a real art.

This is why you want to have a signal with a very high average power  
level, but one which is also not wider than necessary.

Re: [Elecraft] VP6DX on 160 Elecraft Mojo

2008-02-14 Thread WA6L


Congratulations, Julius!   That pretty much parallels my own experience.  I
got them on 160M CW with my K2/100 into a top-loaded sloper.  When they came
back to me, I was not 100% sure whether they sent CFM or QRM. 
Fortunately, it was the former, and I showed up in their online log.  :-)

73,

John, WA6L

 Worked VP6DX this morning on 160...
 
 I was running my K2/100 (about 90 watts to the tuner
 due to some foldback issues) thru the KAT100 into a
 55' piece o' wire with a few radials, none any longer
 than 40'. It was a solid no repeat QSO.
 
 Those folks have good ears and they were a solid copy
 without a Rx antenna on the K2.
 
 Don't be afraid to try them, even if you think your
 antennas are lacking.
 
 Worked them on 12M CW as well, been ages since I even
 heard anyone on 12!
 
 GL to all in ARRL DX this weekend. It's looking like a
 Low Band show.

Re: [Elecraft] D-104 and Radio Shack electret element

2008-02-14 Thread T. David Yarnes
I have not tried it on the K3, but I have done this many 
times in the past with other rigs.  I know W5JAY has played 
around with that also on his Pro III, and got very favorable 
comparisons with his Heil microphones.  All you need to do 
is find some old microphone housing, put in the RS electret 
element, and wire it appropriately.  I think you will be 
pleasantly surprised!

Re: [Elecraft] Not All Hams are Technicians (WAS: Microphones)

2008-02-14 Thread Mike
I very seldom post to this list - taking up even more bandwidth doesn't seem to 
be what the list needs lately Hi, but this thread sparked a response so I 
thought I'd share it.

Although I was into CB in a big way back in the day (when it was as polite 
and compliant as we sometimes wish amateur radio was today), college, career, 
and family intervened until 2006 when I finally became licensed at age 44 
(passed my General in 2007, shortly after rushing to pass the code before the 
requirement was eliminated).  At that time I was one of those interested in 
operating with the best equipment my budget could allow, but I had/have no 
real electronics experience, other than doing all my own soldering when needed 
and one summer as a teenager when I worked for a neighbor who was in the 
process of inventing the first automated wire-wrap assembly line jig.  I still 
remember him trying to beat Ohm's Law into me, without much success.

Since becoming licensed, I actually find the pursuit of learning electronics 
more attractive than operating, most of the time.  I seem to be in love with 
QRP, mostly because of all the opportunities to build.  I still don't know what 
I'm building, but I'm doing everything I can to read, question, and study, and 
hoping that repetition will help!  Currently awaiting my attention at the bench 
are a Pixie II, a Norcal SMT dummy load, one of each of everything Hamgadgets 
sells, and a BLT tuner.  My goal is to use each as a learning project, taking 
my time with each one and understanding the purpose each component serves 
before moving on to the next.  The recent QST article Building to Learn 
couldn't have been more timely.  I couldn't wait to build my KX-1 last year, 
and it turned out great (with some help from Don on the 3080 board!), but I 
have to admit that my approach did not make it a learning experience.

The hurdles these days are time, and access to a willing Elmer who doesn't mind 
teaching stuff that he's known for 50 or more years to someone new.

[Elecraft] K2 NEED HELP TROUBLESHOOTING

2008-02-14 Thread RICHARD MC KINNEY
Completed assembly and all was well until problem showed on Tx.  It was drawing 
too much current at 5 watts.  Also would not go above 5 watts.  I'm not worried 
about that problem right now as I caused another problem.  I removed the 
control board as suggested in 065 of the guide.  Heard relays click as the book 
said.  But when I put the control board back in I lost Rx.  I know it worked 
good on 40 meters as I played with it a few days after alignment II procedure.  
I can inject a signal on 40 meters and the s meter pegs out but it is just 
barely audible in the headphones.  The side tone audio is ok when I key.  It's 
like the Rx is muted.  I can touch pin 2 and 3 of the audio amp and hear finger 
noise.  This Rx problem is not from something installed wrong as it worked fine 
before I removed the control board.  Please somebody tell me I can just push 
some button and clear up the Rx problem so I can chase the problem on Tx.  73

Re: [Elecraft] K2 NEED HELP TROUBLESHOOTING

2008-02-14 Thread Don Wilhelm

Rich,

I suggest you look closely at the connectors between the control board 
and the RF board for a poorly soldered or unsoldered connection.  
Especially pins 35 and 36 of control board P2 and RF board J7.  Also 
pins 1, 2 and 5 of control board P3 and RF board J8.  These latter AF 
control pot lines go to RF Board P1 pins 1, 2 and 3 and Front Panel 
board J1 pins 1, 2, and 3. 

The reason I suspect an unsoldered connection is that you caused the 
problem when you removed/re-installed the control board - and in the 
process, something moved.  An unsoldered connection can work just by 
physical contact for a while, but will break the connection if it is moved.
You can use your ohmmeter to check continuity along all these paths - 
use the schematic to see where the wire starts and ends up.

 I havn't used it yet.  But it seems to work on the audio output from the

 that's the case it seems it would only decode signals that are in your RX

 Isolating the signal you want and narrowing down the filter should give
 you what you 
 
 are looking forI think.  :)  
 
There is a two page write up on this program in the latest RadCom, arrived
today. One of the things it mentioned is that the program apparently doesn't
work well if any filtering is used. It wants a wide band input taken from
the IF, not a regular audio output, or its decoding abilities suffer. Don't
ask me why.

It's most depressing, reading how the software helped the author spot the
exact frequency that successful callers were using, so he could call on the
same frequency and make a contact with the DX right away, while others
without the software, unable to spot the exact frequency to call on, went
unanswered. A key skill that allowed the less well equipped station to get
an advantage over those with more power but less operating prowess, has been
wiped out by a bit of shareware. :(

(To forestall a possible deluge of requests for copies of the article, sorry
but I don't posssess a scanner, even if I was willing the RSGB's copyright.)

you might be able to place an electret element in the case and leave 
the original element in there  You'd have to rewire since the 
astatic has a 3 conductor
plug on the mic housing.   I have placed an electret ( small )  in 
front of a dynamic AKG element in my current station microphone, and 
cannot hear any acoustic interference.

[Elecraft] K3 #379 minor stumble

2008-02-14 Thread Michael E. Dobson
I've run into a minor glitch in the assembly of K3 #379.  I made it 
up to the point of doing the 5W Transmitter Gain calibration without 
a problem.  That went fine on every band but 60M, there I get no more 
than 0.4W and a ERR TxG message when I exit Tune.  The installation 
of the 100W amp and the final steps are on hold until I hear back 
from K3support which means using the K3 in the ARRL CW contest this 
weekend is very much in doubt.


On the other hand, while waiting for a reply I snagged VP6DX on 17M 
at about 22:55Z with my trusty K2 for my first QSO with them.

I got one like that from Maplin several years ago. You could run over it
with a truck and it wouldn't harm it. I've only ever used it on rare
occasions when I've taken the K2 out mobile or portable, but it sure has
earned some unsolicited complimentary audio reports.

As for plug compatibility, my oldest mic has been rewired so many times the
cross-head screws on the plug shell are almost completely burred over.
Fortunately since the K2 arrived in the shack several years ago I haven't
needed to rewire it. It worked with the K3 with no problem.

RE: [Elecraft] K3 Convergence

2008-02-14 Thread VR2BrettGraham

W4TV continued:


 CI-V also allows for multiple controllers, though I
 have yet to see any other application that appears
 to properly implement its CSMA/CD protocol.

There is no carrier switching or collision detection in the
CI-V protocol.  The data packets do not carry any checksum
or sequence number both of which are required for CSMA/CD.
CI-V is a pure aloha protocol - if the packet gets lost or
damaged the originator must resend if it does not get
the expected reply.


CI-V does have collision detection, as every device can
see the serial bus as it sends.  That also makes a
checksum unnecessary.  It is intended that a controller
resend a command if a collision is detected, so there is
no need for sequence numbers, either.

Carrier sense multiple access with collision detection
does not mean any more than that - but what I was
responding to was the assertion that there is not a single
radio that is capable- in either hardware  or software - of
reliably servicing two different radio control applications.
Maybe there isn't, especially if one insists on not working
with the radio as the manufacturer intended.

[Elecraft] VP6DX RTTY QSOs on the K3 -- without a computer

Hopefully you won't think I cheated, but I put a message 
in one of the memory cells  to use for calling.  Working a 
pile-up can get a bit tiresome sending by hand all the time. 
So I put DE W7AQK W7AQK W7AQK K K K  in memory to do my 
calling.  Then when VP6DX came back (after several tries) I 
retuned using the paddle.  I guess you could even put the 
sig report response in a memory, but I chose not to.


But I have a question!  At what baud rate does a message 
come out of memory on RTTY?  On CW its at the rate you have 
your keyer set.  So, should I turn the speed up on RTTY?

We planned it this way  :)  I also recommend that you insert an IM 
prosign (..--) at the end of any message used in DATA modes to truncate 
the usual CW-to-DATA timeout from 4 seconds to about 1 second. The IM 
character is ignored in CW mode.



But I have a question!  At what baud rate does a message come out of

On CW its at the rate you have your keyer set.  So, should I turn the

It's fixed at 45.45 BPS, or about 60 WPM, the most common RTTY 
standard. The keyer speed control has no impact on this. We may support 
other standard RTTY speeds in the future.

CI-V can only see the data it is sending.  Depending on the

sending on the bus at the same time with the local data
masking the remote data.


There are no hardware differences involved - a serial bus
with one device trying to pull the bus low  another device
trying to pull the bus high will result in at least one device
not seeing what it was expecting to see on the bus.

What you describe could happen if the serial bus has been

Re: [Elecraft] K2 8R/keyline-RF Timing Questions

2008-02-14 Thread w2bvh

Steve

I measured this a couple of years ago and put the info in my notebook. 
As you mention, 8R transitions 15 ms before rf output.  It doesn't 
transition back  again until  5 ms after  rf  has  stopped. The timing 
is completely independent of the t-r value set in the primary menu. I 
tried it with t-r=.02 sec and t-r =1.0 sec and the timing was the same. 
This was in cw mode. I don't have measurements for ssb.


I used the info to see if I needed to make external timing circuits for 
a hb transverter I was building. I didn't. And the transverter works fb. 
(I did use fast relays though)


Hope this helps.

RE: [Elecraft] D-104 and Radio Shack electret element

2008-02-14 Thread Ron D'Eau Claire
The Astatic crystal element exactly fits the lollipop housing. It's THAT
big! But it's no problem to remove and rewire. The lollipop top even unplugs
from the stand.

Unlike a lot of modern desk and hand mics, the D-104 was designed around
the element, rather than coming up with a design for the case and plunking
the element inside! That was true of most of the old microphones. For
example, the Heil Heritage microphone is a copy of the old ribbon
microphones used for broadcasting in the 1930's and 40's. The long, tall
shape of the enclosure was dictated by the shape of the microphone inside,
which used, literally, a ribbon of flexible metal in a magnetic field.
Another enclosure for the same ribbon element is the Heil Classic that was
another 'standard' in broadcasting studios everywhere. In both cases, the
pop screen so often seen put in front of the microphone today is part of
the mic and dictates the separation from the grille and the element inside.
It's placed just inside the metal openings. 

Similarly, the more round mics were either miniature crystal elements or
dynamic elements which were that size! 

Heil has used these designs for good reason. People associate those mics
with quality and performance, based on old associations. Heil can use them
because today's elements are so small they can be put inside almost any
traditional enclosure. 

Even the most technical of us still responds to fashion -- at least some
of us do.

Ron AC7AC

-Original Message-
you might be able to place an electret element in the case and leave 
the original element in there  You'd have to rewire since the 
astatic has a 3 conductor
plug on the mic housing.   I have placed an electret ( small )  in 
front of a dynamic AKG element in my current station microphone, and 
cannot hear any acoustic interference.

   Interestingly, one of the big exceptions is the inexpensive
  little Radio Shack electret element. It comes with a frequency response
  chart showing a very flat response across the audio spectrum.
 
 If you are looking for flat then these are a great place to start,
 however the design of the housing may have quite an impact on how things
 sound, this can be used to your advantage to create a presence peak or
 LF roll off.
 
 My own headset is based on a salvaged electret condenser mic with some
 audio tailoring done by means of a simple R/C filter, being lazy I
 copied the circuit of an Icom handmic. It works great and cost me almost
 nothing.
