The auto decoders work pretty well with machine sent code, but not with the average operator sent code.  FLDIGI seems to work better than the others I've tried - free.  Also includes other digital modes. 

Over time you will learn to recognize the operator by the "swing" in his fist ... now you're having fun!!

 

Using LTspice and it runs just fine on XP/SP3.   I know where you came from and this will make you smile - ALOT!

Morning Tom,

I have a scope, VTVM and DMM on the bench (collected over the years) and each has its use. Use them pretty much in the order listed.  For some reason I've never really trusted DMM - think its because the early units where really flaky - the current models are much better. 

Practically, I can watch the scope or VTVM out of the corner of my eye, but the DMM requires a little more focus to interpret. No question that a good high impedance analogue meter is better for peaking or tuning L/C etc. A 260 may not meet your needs for high impedance.

A Simpson 260 is a great tool - carried one for years as a tech and engineer (power company) - last one I personally had was stolen (probably wound up on Ebay???)

But if you are going to be working with Tube type stuff - get a good scope and learn to use it.
