[1000mp] filters, audio, etc.

[Steven Olson]

I am new to the list and considering the purchase of the Mark V and have a 
couple of questions:

1.  I work both ssb and cw and was wondering what recommendations folks 
have for configuring filters for ssb and cw.
2.  Has anyone wired the "audio in" directly to the transceiver (I have 
done so with my icom rig through the accessory  jack).
3.  Any experience using studio/xlr mikes (other than Heil products) and 
the Mark V?

Any help would be appreciated.
