Hi Joe,
Using dropbox is a good idea. Thanks for posting those interesting QST pages.
About the bloat -- a MIME base64 encoding is 6-bits / 8-bits = 75% efficient.
Each line is 76 characters plus 1 or 2 overhead (CR+LF) so it drops to 73.077%.
That means the ascii email is 1.368 times larger than the original binary attachment.
In your post, the base64 size (3490102) divided by the PDF size (2550458) = 1.368, exactly as expected.

That PDF shows 2.4 MB on this end. I guess the MIME encoding really bloats it.

Tom,
Thanks, but I already reposted with links to that PDF and a followup. Feel free to post a permanent copy of both. I will delete the linked files on my end at some point.

Hi Joe,
That PDF attachment was 3.4 MB (too large for the list) so I put a copy here:

More goodies from QST. Attached is an article about the very first ARRL Frequency Measuring Test.
