I don't think that you will have much luck with the MFJ used as a grid dip
meter. You will need a decent grid dip meter.

##  I have never been able to grid dip anything with either my 259 or  259B.
That was using both optional grid dip  coils.  I tried every simple circuit you 
could think of
just to test that feature.   Like a simple cap and coil in parallel.  Even 
tried different cap + coil combos to no avail. 
Series, parallel,   you name it, didn’t work.   Finally threw in the towel.
Even  W8JI sez they don’t work  Dunno why they sell the pair of optional grid 
dip coils.   Nobody
else here in town had any luck  either.  Only thing that works is a real grid 
dip meter.
