Best SW Frequencies to Try First on ATS Mini V4

Shortwave broadcast schedules shift over time — treat these as a general starting map, and check a current online SW schedule database for exact active frequencies/times before assuming any specific one is still active.

General SW Broadcast Bands to Scan

• 49m band (~5.9-6.2MHz): historically one of the most active broadcast bands, especially evenings
• 41m band (~7.2-7.45MHz): another consistently active general broadcast band
• 31m band (~9.4-9.9MHz): strong daytime and evening activity from major international broadcasters
• 25m band (~11.6-12.1MHz): good daytime band
• 19m band (~15.1-15.8MHz): good for daytime DX, propagation-dependent

Ham Radio SSB Bands (see the SSB guide for LSB/USB convention)

• 40m (~7.150-7.300MHz, LSB): reliably active with ham conversations most evenings
• 20m (~14.150-14.350MHz, USB): strong daytime ham activity, good DX potential

General Tips

• Shortwave propagation is generally much better after dark, especially on lower frequency bands — try evening listening sessions first if daytime scanning seems dead
• Use Seek mode to auto-scan a band rather than manually stepping through frequency by frequency
• Check a current online shortwave schedule database (search "shortwave frequency schedule" for current options) for exact active broadcaster frequencies/times in your region before assuming a specific historical frequency is still in use
