[Elecraft] [Elecraft_K3] Re: Heil Proset Headphones

[w7aqk]

The Elecraft Pro Set is essentially a duplicate of the Heil IC Pro Set.  The 
IC version of the Heil was, as I understand it, introduced as a suggested 
model for Icom radios (thus the "IC" designation), and has an electret 
cartridge.  Electrets apparently work quite well with Icom gear, and they 
work very well with Elecraft gear.  As most already probably know, many of 
us who have Elecraft K3's and K2's have opted for the Yamaha CM500, which 
also has an electret cartridge, and is considerably cheaper than Heil's 
models.  All the bias requirements for electrets are handled through menu 
options on the K3, so it is very simple to use them.  It also plugs directly 
into the back of the K3, so you don't need any of the adapters.  The K2 will 
also provide the necessary bias, but you have to change a connection 
internally.  I personally don't find any particular benefit to either the 
Heil or the Elecraft models, and I have both.  The Yamaha works great.

Irwin,

The main difference is in the microphone element.
The PS-6 has the Heil HC-6 element which is a wide range dynamic element
which has a relatively low output.
The ProSet-K2/K3 uses an electret element which has a high output level
- it needs to have bias turned on.

The K3/K3S is quite capable of handling either of them.
