It sounds fine, though I heard through another on the list that they had success with their Proset with HC5 without the preamp. I tried it out with a friend listening, and it worked just fine, and is now what I use. I do notice that it is impacted by the nearness of the mic to my mouth, so it would likely have more dynamic activity with a preamp, but I am driving to a full signal with the current setup.
If you are not getting good reports with the MH2, then switching to another, similar mic (or even the HC5) will not help. First thing you need to do is check you passband, make sure they start at 300hz and then listen to both U & L sideband on another rig. - David Wilburn [EMAIL PROTECTED] K4DGW K2 S/N 5982 On Sun, 2008-01-06 at 13:29 +0100, Karsten Eppert (DK4AS) wrote: > I have purchased together with my K2 an MH2 microphone short before it > was discontinued two years ago. > The reports I receive always state, that the mike has too much bass. > The filters of my K2 were checked with spectrogram and - to me - appear > correct. > > In parallel I have tried a cheap boomset with an electret-mike.

I ran the checks while beta testing the IMA (Internal Mic Adapter) produced by UN-PCB. _http://www.unpcbs.com/_ (http://www.unpcbs.com/) Al WA6VNN **************Start the year off right.
