Recently, I’ve been getting questions about whether a ham needs to log radio contacts, whether they need to submit a log, and how to do it. Logging is a complex topic that can require a long and detailed explanation, but I am going to focus on the questions I’ve been hearing lately. I’ll also provide some links for further investigation. For starters, the ARRL has a good introduction to logging.
A paper ham radio log
Why Keep A Log?
The FCC does not require you to log your amateur radio contacts. Many radio amateurs, especially if they just operate casually on 2m and 70 cm, don’t bother to keep a log. Probably the most common reason for having a log is to have a record of your radio contacts, in terms of stations worked, on what band and what conditions. This might be just for your own personal satisfaction or you might want to keep track of these contacts so you can get credit for an award, such as the ARRL Worked All States (WAS) award.
Paper or Electronic?
The Old School way of keeping a log is on paper as shown in the figure above. This approach is simple and reliable technology but is quite limited in the information age. These days, most hams that record log information store it electronically. Imagine that you log thousands of contacts over time and then want to find a particular callsign or location. Much better to do this electronically. There are many good software programs available, too many to list here. I currently use Amateur Contact Log from N3FPJ. The good news is that there is a standard file format for storing and moving ham radio contact information: Amateur Data Interchange Format (ADIF). If you want to change logging software, you export an ADIF file and import into the new program.
I Worked a Contest Station, Do I Have to Submit a Log?
Sometimes radio ham works a few stations that are active in a particular contest and they wonder if they must submit a log to the contest sponsors so that these these stations get credit for the contacts. The almost universal answer to this is: No. Don’t worry about submitting a contest log if you aren’t really “in the contest.” The stations you work still get credit for your contact with them. (This is true for all major contests…I am still looking for a contest where this is not true.) Contests are designed to encourage activity, so they want everyone to join in, even if they aren’t all that serious about contesting. (The contest sponsors will appreciate any and all logs submitted, so consider that.)
If I Am Actively Working a Contest, What Do I Do?
If you are actively participating in a contest, you should use a logging program that is tuned for that particular contest. This is important because the contest logging software knows about the scoring for the contest and lets you know if you have already worked a station you hear. The most popular logging software for contesting is the N1MM Plus software. There are other programs you can consider. Typically, you would use N1MM during the contest and then export the info into an ADIF file, which is imported into your “main” logging program.
What is a Cabrillo File?
While the ADIF file format is most universal in ham radio logging, there is another file format used for contesting. This is the Cabrillo file format. Your contest logging software can generate a Cabrillo file for submitting to the contest sponsor. You may also want to generate an ADIF file to import into your normal logging program.
I Worked a POTA Station, Do I Have to Submit a Log?
Parks On The Air (POTA) is set up so that only the activator station submits a log. If you are working an activator station, you are a hunter station. The POTA scores are all based on the activator logs and hunters cannot submit a log. What you can do is register on the POTA website to see the contacts that the activators have submitted for you.
I Worked a SOTA Station, Do I Have to Submit a Log?
Summits On The Air (SOTA) is set up so that both activators and chasers submit logs to the SOTA website. However, the SOTA system operates on the honor system, so an activator can claim a contact with you without you submitting a log. So if you hear a SOTA station, go ahead and work them. You don’t have to submit a log. On the other hand, if you want credit for chasing a summit, you need to submit a log. So that activator is fine not having you submit a log but you may want to do that to get credit for you.
How Do I Get Credit For Working A Country?
The gold standard for chasing countries, I mean entities, is DX Century Club (DXCC). If you are interested in DX, you should register with Logbook of The World (LoTW) with the ARRL. To get credit for working an entity (country), you need to submit your log and it must match the log submitted by the DX station. This is a higher level of confirmation because both parties must submit the log info and it must match within reasonable error limits.
There are other award systems for working countries, offered by QRZ, eQSL, etc.
How Do I Get Credit For Working a Grid on VHF/UHF?
The VHF UHF Century Club (VUCC) is the VHF/UHF equivalent to DXCC. Here the emphasis is on working maidenhead gridlocators on the bands above 50 MHz. Again, Logbook of The World is the database that authenticates confirmed contacts on these bands. Both parties must submit the log info and it must match within reasonable error limits.
What If Someone Needs My Log Submitted?
Most of the time, us normal hams are not considered DX. That is, that other station in the Cayman Islands doesn’t really need our contact confirmed. But there are exceptions. You might be in a state the other station needs confirmed. Or maybe it’s your county they need. In such a case, you might want to make a special effort to provide your log information to the right database. It will depend on what the other station needs…if they are going for an ARRL award, then Logbook of The World is the right place to upload your log. But they might be after a QRZ award or eQSL award, in which case you would need to provide your log to those websites.

These are some of the questions I’ve been hearing.

Anything else to add?
Everyone wants to know how their signal sounds on the air and often the best way to find out is a signal report from other ham radio operators. The standard signal reporting method for amateur radio is the RST (Readability-Signal Strength-Tone) system. See Practical Signal Reports on HamRadioSchool.com. When using 2m FM on Summits On The Air (SOTA), we can Continue reading SOTA Signal Reports Using 2m FM→

Everyone wants to know how their signal sounds on the air and often the best way to find out is a signal report from other ham radio operators. The standard signal reporting method for amateur radio is the RST (Readability-Signal Strength-Tone) system. See Practical Signal Reports on HamRadioSchool.com.
When using 2m FM on Summits On The Air (SOTA), we can simplify the signal report. Because it is a voice mode, we drop the reading for Tone and just give RS reports, so a perfect signal on voice is RS 59 or simply “five nine.” The Readability report is a number between 1 and 5, while the Signal Strength report goes from 1 to 9. (See the listing at the bottom of this article.) The signal strength generally corresponds to the S meter reading on your radio but most FM rigs have very basic meters. Some don’t provide a meter reading at all. The photo to the left shows a typical bar graph on a Yaesu FT-60. Don’t expect high accuracy, so if the meter reads full scale, give an S9 report. If it reads half-scale, that’s probably S5, etc.
On VHF FM, signal reports may also be given in terms of FM quieting. A strong FM signal is said to “quiet the receiver” since there is virtually no noise present in the received audio. As the signal strength is decreased, noise starts to appear on the received signal. At lower signals levels, the noise increases dramatically and the signal becomes unreadable. This dramatic increase is called the threshold effect, meaning that FM signals do not gradually fade out, they tend to fade quickly into the noise. The key idea here is that you want your signal to be strong enough to be above this noise threshold. In terms of a signal report, a strong signal may result in a “full quieting” report. If the signal is less than full quieting, you may hear a report like “90 percent quieting” or “you have about 10% noise”, which both describe the amount of noise present in the signal. If the signal is really noisy, the report might be “50% quieting.”
Keep It Simple
For practical 2m FM operating, don’t overthink these signal reports. If the signal is easy to hear and is full-scale, give a 59 report. If it is easy to hear but the meter reading is less than full scale, reduce the signal level report to something like 56 or 57. If there is some noise present, you might want to reduce the readability to 4, so maybe give a 44 or 45 report. (Usually, if there is a readability issue, the signal strength will also be lower.) If you are having a difficult time hearing the signal, it’s probably a 33 or less. Readability of 1 or 2 is rarely used because it indicates you are not actually hearing the other station.
One final note is that sometimes the operator on the other end is looking for a more critical evaluation of his signal quality. If he says something about “checking out this new microphone” or “have been working on solving an audio problem”, that may be the clue to spend a little extra time really listening to the signal and providing more comments on how it sounds. For most of us, we don’t actually get to hear our own signal on the air, so it’s very helpful to get quality feedback from other radio amateurs.
