[Elecraft] K2 on Digital stuff

[KJ3D]

Hello Group,

I have been using an MFJ-1279 for digital (just PSK_31 for now) and it seems
to be very well behaved.  External sensors confirm a clean signal.  Bit
pricy, but well-featured.

My question is:

Have any of you used the MFJ digital software (RadioCom4 or RadioCom5)?

Both are very expensive for software, and I don't want to take a blind risk.
They seem to offer everything but fresh grilled cheese sandwiches.  Are they
worth the $$$?

TIA,

73,
