The ARRL International Digital Contest - What is It?  @ND3N
Uploaded February 2022 | Updated September 2026, 6 days ago
The Objective of the ARRL International Digital Contest is for amateurs around the world to contact as many other amateurs in as many 4-digit Maidenhead grid squares as possible, using non-RTTY digital modes.

At the end of the video my camera started to adjust the brightness of the image. It's a little distracting, but hiding my ugly mug in the shadows can really only make everything better - right?

Recommended Frequencies:
FT-4 Recommended Sub-bands:
1.836-1.840
3.580-3.590
7.080-7.090
14.080-14.090
21.080-21.090
28.080-28.090
50.330 to 50.340
When choosing your operating frequency, set the radio dial at the bottom of the sub-band and QSO with stations on audio frequencies within the radio passband, typically 2.5-4 kHz wide. If a sub-band becomes crowded, move the radio dial frequency up in 2 kHz increments, as needed. (For example: 7.080, 7.082, 7.084, 7.086 and 7.088).

FT-8 Recommended Sub-bands:
1.840-1.844
3.590-3.600 (No Digital above 3600 – remember your pass band))
7.090-7.100
14.090-14.100
21.090-21.100
28.090-28.100
50.340 to 50.350
When choosing your operating frequency, set the radio dial at the bottom of the sub-band and QSO with stations on audio frequencies within the radio passband typically 2.5-4 kHz wide. If a sub-band becomes crowded, move the radio dial frequency up in 2 kHz increments, as needed. (For example: 7,090, 7.092, 7.094, 7.096 and 7.098).
