The WSJT-X software used for making FT8 contacts has IARU Steps 1, 2, and 3 embedded into its communication protocol. FT8 is intended to work well under weak-signal conditions, so the software implements a rigorous use of information exchange. Appropriate use of this software guarantees a valid QSO. The QSO starts with one station calling another (...
Radio contacts during VHF contests can be a bit casual: one operator calls another (callsigns exchanged) and they tell each other their grid locators. IARU Step 3 (the QSL or acknowledgment) may be assumed or perhaps one of the operators just says thanks or 73 to indicate the contact is complete and they are signing clear. But when the signals are ...
HF contests are fast and furious, with a high value placed on quickly making contacts. Thus, they tend to use the bare minimum to complete a QSO. Let’s take the example of a Big Gun station making multiple contacts in succession, otherwise known as “running.” Here, ZF1A is working the CQ Worldwide DX Contest with a number of stations calling him. H...
From the POTArules: “POTA does not require a formal exchange, though many activators will wish to receive real signal reports, names and locations.” My experience is that the park Activator usually sends a (real) signal report and the park number (e.g., K-4404). The Hunter usually sends a real signal report and state. Something like this: KØNR call...
The general SOTA rules state “QSOs must comprise an exchange of callsigns and signal reports, it is strongly recommended that the summit identifier be given during each contact.” SOTA contacts are similar to POTA contacts in terms of format, except the summit number (e.g., W0C/FR-004 ) is exchanged instead of the park number.
Meteor scatter (MS) is an interesting case, mostly because it can take a long time to complete the QSO. The two stations are transmitting to each other on alternating time windows hoping that a meteor will streak by and leave an ionizing trail so that a radio contact can be made. It is common for an MS QSO to take 30 minutes or longer. The message ...
Sep 14, 2021 · It is relatively common to receive QSL cards from newer hams who have filled out the QSL incorrectly or left off critical pieces of data. In this blog, we’ll go over the basics of QSL design, how to fill them out, and a bit of etiquette when requesting a QSL from another ham.
QSO was often used in the early days of amateur radio when the range of a station was limited and stations relayed messages from one to another. Nowadays, we mostly use QSO as a noun, meaning a contact with another station.
QSO is an initialism that means quasar, a type of astronomical object with a very high redshift. The term was coined in the 1960s and is used in astronomy and astrophysics.
