Echo Charlie are illegal international freeband radio frequencies similar to the 11 meter band we all use so much. Although Echo Charlie is a section of particular frequencies, we will be dedicating all freeband frequencies, other than the popular 11 meter band, to Echo Charlie.
The Echo Charlie freeband frequencies are:
calling 3470 LSB
calling 6670 LSB This is actual Echo Charlie
10400 USB (Experimental freeband frequency)
calling 13970 USB (13930 used when 13970 has jamming)
Calling 13555 USB
calling 18030 USB
calling 20930 USB
Look on the Freeband chat and cluster for activity, some Freeband members will be regularly active on Echo Charlie, using the FB call sign.
When using these bands, please remember they are close to military and aeronautical frequencies, and care must be taken. Please QSY from the calling frequency after you have made contact. Often there will appear to be little activity, but after a few calls usually contact can be made, many stations monitor 6670 and 3470 calling frequencies. 6670 is best during the afternoons and 3470 works well late into the night with frequent networks covering a lot of Europe (UTC)
Etiquette is a cross between HAM and 11m, most operators are courteous and polite. Spend some time listening before TXing on these bands. Operators will always welcome break (On the side or QSK) stations.
EC users are always looking for long distant DX as well as local contact. Europe contact is widespread with many stations all over south and north EU, outside EU is rare as, apart from SA 21m illegal band, there seems to be little active EC stations from other continents.
Feel free to ask any questions.
