Broadcasting your radio from your home using the SHOUTcast Radio DNAS Application

At the moment the most used program is UA1AAF. It is an excellent program written by Boris, UA1AAF, to handle ARI International DX Contest. It can simulate K1EA or N6TR workings; it will be possible to connect the RTX to the computer using a standard interface in such a way as to transmit directly in CW from the keyboard; most of the controls are like K1EA's CT and N6TR's TR ; on line help provides almost all the information necessary for using the program. Is possible to insert QSO after the contest. An appropriate utility in included for conversion in ADIF format. The program is very small and therefore works without any problems on any IBM compatible computer with DOS 3.3 and over or Windows 95/98.

Operating in the Nordic region often requires specific call sign lookup tools, and this resource offers a dedicated search service for Swedish amateur radio operators. Users can query the database by entering a call sign, a family name, or a city, facilitating the identification of hams within Sweden. This functionality is particularly useful for DXers attempting to confirm contacts or for local hams seeking to connect with others in their area, leveraging the official data provided by the Swedish Amateur Radio Society (_SSA_). Such a lookup service streamlines the process of verifying contacts for awards like _DXCC_ or for general QSLing purposes. While many global callbooks exist, a national service like this often provides more granular and up-to-date information for its specific region. The ability to search by city can be especially beneficial for local rag-chewing or for coordinating activities within a specific geographic area, offering a practical complement to broader international databases.
