I'm new at IFR so this may be off base, but... the chart says radar is
required, so I'm guessing you can only use this with radar vectors.
There isn't even a proc turn shown.



The chart doesn't say "RADAR REQUIRED", it says "DME or RADAR and ADF
REQUIRED". You can fly it without radar assistance as long as you have DME
and ADF (or suitable GPS) and navigate via Falmouth VOR/DME.



I never was very good in grammar, but what is the parsing order in the
above. Is it "DME or (RADAR and ADF)" or "(DME or RADAR) and ADF?" I'm
assuming English has an order of evaluation as does mathematics, I'm
just not familiar with what it is. I would have read this as requiring
either DME or requiring RADAR and ADF, but that isn't how you
interpreted it and I frankly don't know which is correct from a language
perspective.

DME or Radar...one of the other
ADF no matter which of the "ors" above you have.

Look at the context. There are radar fixes where there are DME fixes.
