No reason, except it's a little more difficult to carry around a 10m antenna
than it is to carry an Arrow or Elk :-)

Why does Mode A have a normal transponder, whereas Mode B uses an inverting
transponder?

Nope! By all means, work it in Mode A if you're equipped!

Inverting transponders exist to reduce the total Doppler shift. Since the
Doppler shift on 10 meters is so low, there's no real need to invert the
passband.

Hi John,
It's a bit involved without having a white board or the use of hands to wave
around but maybe I can state the principle in 25 words or less ...
A transponder is pretty much an RF mixer where a local oscillator (LO)
frequency is mixed with an input signal. The resulting output of the mixer
is a combination of ...
1. the LO frequency (call it F1)
2. the originating input frequency (call it F2)
3. a resultant output of LO-input freq (F1-F2)
4. a resultant output of LO+input freq (F1+F2)
Depending on which resultant mixer output you transmit you'll be inverted or
not inverted. Perhaps that is too simple of an explanation to make sense.
More details thanks to google like this one:
http://www.radio-electronics.com/info/rf-technology-design/mixers/rf-mixers-
mixing-basics-tutorial.php
More experts around here will tell better :-)

I agree,
I Love Mode A
And even more basic equipment can be used to make a contact on Mode A.
No expensive all mode VHF/UHF rigs needed.

That was true in the 1970s, but today working VHF/UHF linear transponders
can be done quite inexpensively. Certainly for no more than an average HF
station.

I have been observing AO-7 quite a bit lately and I have noticed three
broadband humps in my panadapter display. I also see these in W5RKN
panadapter captures at:
https://drive.google.com/file/d/0B-Jez46MB5RaMzV0RlhmWHNWcjg/view?usp=sharing
This confirms these are being transmitted from AO-7. They disappear
immediately after the mode switch in his captures. I also observed this
today at 31 MAY 2017 about 19:03 UTC during a mode switch.
Does anyone have an explanation of why these occur? The obvious might be
some sort of signals on the uplink. Has anyone identified if these
signals occur throughout the world or just in specific areas. If you
look at these, a large part of AO-7's power output is being used to
transmit the broadband humps.

They are definitely internally generated. Someone who's been around longer
might be able to say if they've been there since the beginning or if
they're possibly the result of intern circuit degradation of some type.
Incidentally, the noise peaks coincide with the most sensitive parts of the
transponder. The middle is the weakest.

This has been well documented from the earliest days of AO-7 in the 1970s.
They occur throughout the world.
