@bd - I tend to agree, I got into satellite ham stuff for a while, interesting problems with antenna gain, different Doppler shifts on different frequencies for the up and down link, tracking - made 5 or so contacts, got bored so moved on to microwave stuff for a while.
EME stumped me - so I had a 'tantrum' and packed it up - I will get back to it eventually.
Currently repairing old gear some fun, some head f**k at times. If I get too annoyed I go mountain bike riding!
I do think I have a short attention span!
