Questio when using a Heil Proset

I have just received my K3 and have been using it on data, and it is working well,
But I have a problem, when trying to use the Heil Proset it receives ok but when I try to
use the PTT I get a loud audio noise over the top of my speech, it sounds like someone
giving a loud "raspberry".
Trying the MH2 hand mic everything works perfectly, there is no noise and using the monitor,
my speech sounds normal.
The problem with the Proset also occurs if I try and turn on the K3 manually.

Ideas please, what have I set up incorrectly, or is it the headset?

Regards to all

RE: Questio when using a Heil Proset

Hi Ross,

Looks like you have to switch OFF the bias. Use Main Menu item MIC SEL to
do that
If the MH2 works OK that means Bias is ON now. For the Heil ProSet (with #4
or #5 dyn. element) you might need the HI range mic gain (you can set that
in the same menu). See p.51 of the Owner's Manual (rev.D).

Ross,

If the bias turns out to be your problem, know that you can run the Heil
Proset from the rear panel jacks and the MH2 from the Front Panel mic
jack. The bias settings for the two mic inputs can be different. Just
decide which mic you want to use and select that one in the menu - it is
quick and easy.

In reply to this post by Ross Biggar

Ross:
I am having the same results with a Warren Gregoire TR200 head set with boom mic. (electret element)

The MH2 works just fine.

I am feeding an end fed wire directley from the K3. I guessed that RF feedback was the problem. I plan to have a balanced antenna fed with ladder line up soon. I hope that the TR200 will work ok then.

The TR200, used as a headset only sounds great. I am 80% CW and use the head set most of the time for CW and sometimes on phone, with very good results.

The antenna is 150' of insulated wire laid on the grass, sort of works ok on 80, 60, 40. Have to move it to mow the grass.

Re: Questio when using a Heil Proset

I also have the Heil ProSet and have been having a similar issue. The monitored audio sounds rough when speech compression is added. Without compression, the audio is normal. Regardless of compression or not, the transmitted audio is normal according to reports received while in QSO. I haven't been able to track down what is causing the rough audio in the monitor.
