[1000mp] PSK w/Rascal??

[KJ7UN]

    I've been trying for days, and can't get my 1000mp Mark V set up for
PSK.

    I'm using a "Rascal" and the packet port in the back of the radio.  I
don't

    know what else to do or what to adjust to make it work.  I had an older

    rascal (which broke) where I plugged into the mic jack and then adjusted
mic

    gain and power to get low ALC and about 10 watts out.  But with the NEW

    setup the Rascal guy insisted I must use, I don't know how to do it.  Is

    anyone using a Rascal with their 1000mp for PSK?  Or RTTY for that
matter?

    I need some help and I'm all googled out.

    Thanks!
