Comments on MFJ DSP?

I would appreciate receiving comments on the MFJ 784 DSP. In particular I am
interested in its use/performance for SSB contesting. Andy, GM0ECO will be in
the states next week and wants to get a DSP unit before returning to the UK.
I have suggested the DSP 9 or 9+. I know nothing about the MFJ.

Perhaps, but subjective tests (i.e. operating) definitely showed that the
ground mounted configuration achieved much better performance.

There's still a lot of black magic when it comes to antennas ...


l QSL BLACK MAGIC ,,,, and in my case, my subjective tests showed
a far better signal and results with the antenna elevated to 20 ft and the
subsequently elevated radials.  Of course, one of the problems may have
been that the ground mounted located was blocked by other houses
and fences I didn't consider.  Maybe if you had a CLEAR SHOT and it
was ground mounted you didn't see any difference.....all I want to do know
is figure out how to let the Bermuda Telecommunications Officer
let me run a kw and get a VP9 call for contest weekends!
