The FCC has no requirement to identify the station you are speaking with, or to provide signal reports of stations being contacted. There is currently no longer a mandate to submit any logs. Interference to other amateurs is bad radio practice, and should be avoided where possible.

There are online services called "spotting networks" where people can post which callsigns they have been able to hear / make contact with. In a contest it is nearly always against the rules (and always considered bad form) to "self spot" -- that is, to post your own callsign and frequency to the network.
Don't do it =]

On the HF bands, for example, operating on the “WARC bands” is normally prohibited. Therefore, 30 meters is one band on which amateur radio contesting is generally excluded. (E2C03). The other “WARC bands” are 17 meters and 12 meters. They were named after the World Administrative Radio Conference, which in 1979 created a worldwide allocation of these bands for amateur use. Due to their relatively small bandwidth of 100 kHz or less, there is a sort of gentlemen's agreement that the WARC bands may not be used for general contesting.

146.52 is the
National Simplex Calling Frequency on the 2 meter band. Calling frequencies are meant for initiating a contact and then QSY.

QSL cards are sent to confirm radio contact. Knowing that, it makes sense that a QSL Manager is someone who handles the sending and receiving of confirmation cards.

The Cabrillo standard file format has revolutionized the world of amateur radio competitions. Log files can now be emailed in for adjudication from a variety of different logging software programs.

Intentional or unintentional interference and jamming signals are rejected because they do not contain the spread-spectrum key. Only the desired signal, which has the key, will be seen at the receiver when the despreading operation is exercised.
Hint: Question and answer have Receive and Spread Spectrum in them.

Amateur stations transmitting in foreign countries or regions may have different operating privileges than the receiving stations. In order for a contact to be made, the DX Station must transmit on his authorized frequencies and receive the frequencies permitted to the responding stations.
Also, separating the transmit and receive frequencies can cause less of a "pile up" of callers for the DX station.

In pileups, there are a multitude of operators all transmitting at once in the hopes that the other station (in this case the DX station) will hear their call sign and answer. It's usually hard to pick out
Knowing this, process of elimination:
Sending full callsign and grid square would be annoying/confusing because grid squares are also comprised of letters and numbers which could be mistaken as a call sign.
Sending only the last two letters is brief, yes, but leaves a lot of room for confusion because there's a chance that there's someone else in the pileup that also has those two letters. Also, the DX station will just have to ask for clarification if they hear you, which is a waste of time in pileups and contests.
Sending the DX's call, "this is", then yours, etc. is way too much repetition. Also, it's pretty clear if you're in the pileup that you're trying to reach the DX station. No need to say their call repeatedly, too.

As solar flux decreases and the maximum usable frequency (MUF) becomes lower long distance traffic on the higher frequency bands are the first to vanish but conditions may still allow traffic at lower frequencies.
Study tip: Sun gets lower in the sky at sunset....lower frequency.
