Are these typos or is your math really that bad?

I'm expecting to be able to make real baseline measurements tonight.
My receiver (Icom 718) cannot really go past 30 Mhz so I'm restricted
to measuring harmonics' strengths below that frequency.
So here are my plans for measuring. For the 30 meter band, since I'm
on dummy loads (no signfiicant radiation) I'm going to sneak slightly
UNDER 10 MHz so I can catch the important 3rd harmonic on the ICOM 718:
Fundamental 2Har 3Har 4Harm 5Harm 6Harm 7Harm
3.505MHz 7.010 15.515 14.020 175.525 21.030 24.535
7.005 14.010 21.015 28.020
9.995 19.990 29.985
14.005 28.010
Although that doesn't cover all the bands, the problem on the higher
bands shifts to spurs, which the Low Pass Filters aren't as well
targeted at --- but hopefully with just these baseline measurements, the
proof-of-concept of simple-minded daugherboard addition of a separate
relay to avoid relayccontact-to-relaycontact blow-pass will be either
proven or disproven.
I had hoped to make these measurements this morning but was not able to
get that done before going back to work. I have the next several days
"off" so this may speed up.
