I use wget over FTP, which defaults to Binary mode.
The files begin with -----BEGIN PGP MESSAGE-----, end with -----END PGP MESSAGE-
----.
Would ASCII mode be better in this case?

You're right, I used the file's copy which is not the right thing to do when 
troubleshooting. However, GnuPG rejects the copy, too. To make sure, I've 
retested, by having PGP decrypt the file that's on the GnuPG box, working  
directly from the PGP box, reading the fil on the GnuPG box. Again, PGP works 
OK.
I was hoping I only had to use some special switch on the commandline to get GPG 
to work...
