mike selection

[John Wiener]

I am just starting the RF board so I still have plenty of time...I'm  
a little puzzled about choice of mic.

Is there a difference between the Proset K2 on the Elecraft site and  
the Proset Plus on the Heil site?

How does it compare to the Handi Mic (and which model to select?)?

Frankly, the Heil mics seem awfully expensive.

Why did the MD2/CB1 get discontinued...Is there another mic out there  
that is the same or similar?

The reflector site had a lot of opinions: from Radio Shack to Icom  
and beyond but I could find little in the way of consensus.  Also,  
I'm not far enough with the kit to understand the various rewiring  
requirements and whether I'll end up with limitations down the road  
on choice of mic.

John

There is a big difference in the many mics sold by Heil and even more in
those manufactured by Heil and sold only by specific transceiver
manufacturers - Just saying one has a Heil mic is not sufficiently
informative, there are many variations in the elements as well as the mic
plug pinout.

The Heil Proset K2 has a high output electret mic element and most of the
Heil ProSets on the Heil site uses a low output dynamic element (although I
understand that the one sold for ICOM uses an electret).  The Heil HC-4 and
HC-5 elements ideally should have a preamp if they are going to be used with
the K2.  There are some various changes to the KSB2 board that may improve
the performance, but IMHO, the best solution is to 'bite the bullet' and use
a preamp should you choose either the Heil HC-4 or HC-5 element, YMMV.

Obtain your mic first and then follow the instructions in the KSB2 manual to
properly plug the mic configuration header to match the mic's signal pinout.

John,

Although I have no 'hands-on' info about the Proset K2 or Handi Mic, I have
been using for about 2 years a ' genuine ' Heil Proset Plus Heasdset / boom
mic (HC4 and HC5 elements) with my K2/100 and other rigs. With the mic about
3 inches from my mouth, my K2/100 #3255 delivers 100w PEP without difficulty
on all bands when driving a calibrated 50 ohm resistive load, without the
use of any form of additional audio preamp. I suspect that if either of
Heil's HC4 or HC5 mic elements are used in a desk mic, an audio preamplifier
might well be required since the distance between mic and mouth is usually
more than 3 inches in this case.

Even though I spend most of my SSB time 'brawling' (hmmmm) in pile-ups, I
have yet to use the HC4  'DX' mic element in anger. Usually SSbC is at 2-1
with the HC5.

My K2/100 does not contain any 'official modifications' but does contain
some 'birdie killers', and a more beefy phones jack is now at the rear.

Although the cost of the Proset Plus was/is high, I have no regrets.
Features worth mentioning are that the headset is very comfortable, and
remains so during very long periods of operating. Also the switchable
phasing between left and right earphones can be very useful when digging out
very weak signals in the midst of strong QRM., CW or SSB.

The usual disclaimer, just a very satisfied customer.

73,
Geoff
