In this long and sometimes arduous life it helps
to find a kindred spirit that can put our feelings to music. I first discovered this fellow's music in 1973, while
going through a particularly bad time, emotionally. I have never failed to enjoy it since. To me, it is just as good
today as it was when I first heard it.
Maybe you've felt this way.
A nice outlook on life.
Amateur Radio Microphones:
The following recordings are of microphones
that may be used for amateur radio voice transmissions. Some are made for radio use while others were not. The radio types
I recorded by using the headphone output of the W2IHY directly input to the sound card.. The studio types connected
directly to the mixer then output to the sound card. Some of the microphones recorded are the Astatic D-104, Behringer
B-1, and the Shure 55SH. I put the Heil PR-40 in the studio category because of it's wide frequency response, but it was designed
for radio use. As time permits, I may add more recordings later.
Microphone wiring: There are hundreds of sites that
have all the wiring data for radio microphones. However, I usually don't use them anymore. Most radio (Ham & CB)
mics are simple to do. The audio wire is usually inside the shield. The receive wire is closed to switching ground when unkeyed
and open when keyed. The opposite is true for the PTT. Sometimes there is no switching ground, or the switching ground
and the shield use the same terminal. Also, pay attention to any radio T/R switching control, usually electronic
for newer and relay for older. Be sure to match the impedance too. A mismatch here seriously affects output level and frequency
response. XLR is easy, X=ground, L=audio(+),R=audio(-). A hand or foot PTT switch may be needed when using studio mics with
XLR, or just use VOX.
Radio Types:
Shure 527B Dynamic Handheld
Cheap Homemade
Astatic D-104 Golden Eagle
Astatic 10-DA
Shure 444
Electro Voice 622L
Yaesu MD-100A8X
Shure 550L
Studio Types:
Astatic 77A
AKG D220S Dynamic
Behringer B-1 Condenser
Shure 55SH Unidyne Dynamic
Nady RSM-4 Ribbon
Heil PR-40 Dynamic
Of course
the studio types sound better here. But, in the radio world, where the frequency response is limited by the radio, the radio
types hold their own. For breaking through bad conditions they may even be the better choice. The $4 condenser element from
Radio Shack may make one think twice about paying the high cost of some microphones. The Astatic 877L housing I put it in
cost me $7.50 on Ebay. Doesn't sound too bad for a $12 mic. After listening to these myself, I think I should have used a
pop filter on some of them, and probably paid more attention to the levels.
I've had just a little bit (lie)
of whiskey tonight. Now I'm gonna talk. I warned of this at the start of the page. My college has got me teaching at a
high school for the next year. It's has been quite a shock for me. Even though both my kids have finished high school,
and I clearly remember when they attended, I have had my eyes and mind opended lately. I finished high school (dropped
out) in 1971. Things have certainly changed since then. It is taking some effort to accommodate these changes on my part.
However, the more I reflect upon it, things haven't really changed at all. Mostly, I think I have changed. I've grown
into a middle aged man. It seems so ironic to be where I'm at, at this stage of my life, teaching high school students.
Oh well, it's just another stone on the path of life's journey. It's a somewhat difficult situation
for me, but I'm still Army, and I will adjust and overcome. Besides, what the hell, I'm getting paid
extra for it. Time for more whiskey and some music from a CD (album) that I fell in love with in 1977. I've owned this
on vinyl, compact disc, and now an enhanced recording on CD. I really doubt if an SACD will follow. Oh well, this ain't
too bad. The first song evokes more memories than I can count. The second is just damn good. And the third? Well, the
third reminds me of why I like ( and want more of) high end audio reproduction (ps...it evokes memories too). By the
way, it should be clear by now that Emmylou is high on my list.

#1 (Solid State)
#2
Number 3 was recorded twice. #3 1st is
from a Sony Cd player to the Behringer mixer and then to the sound card. #3 2nd is from the Marantz CD player into
the Behringer Tube EQ(set flat) and then to the Dynaco Tube preamp and the Behringer mixer and then the sound card. Compare
using good headphones and adjust for volume as #3 2nd is slightly louder. Both files are large due to high bit rates.
#3, 2nd
