The OffSet Method Explained
Assuming W1AW is calling CQ on six meters 50.260MHz during Random Hour…

1. CQ U7 W1AW (Up 7KHz from calling frequency) W1AW will listen on 50.267 MHz
and swap their Tx Frequency from 50.260 MHz to 50.267 MHz after receiving a call.

2. CQ D7 W1AW (Down 7KHz from calling frequency) W1AW will listen on 50.253 and
swap their Tx  Frequency from 50.260 MHz to 50.253 MHz upon receiving a call)

3. CQ F W1AW (Up 6 KHz from calling frequency) W1AW will listen on 50.266 and swap
their Tx  Frequency from 50.260 MHz to 50.266 MHz upon receiving a call)

4. CQ 267 W1AW (Listening on 50.277) W1AW will switch from 50.260 MHz to 50.267MHz
after receiving a call.

Note: For method #3 above, the letter indicates the number of kHz higher than the CQ
frequency the calling station is listening.
CQC - Up 3 kHz
CQE - Up 5 kHz
CQZ - Up 26 kHz
CQAA - Up 27 kHz. Etc

Assuming W1AW is calling using the OffSet Method during Random Hour on 144.140MHz

1. CQ U7 W1AW (Up 7KHz from calling frequency) W1AW will listen on 144.147 MHz and
swap their Tx Frequency from 144.140 MHz to 144.147 MHz after receiving a call.

2. CQ D10 W1AW (Down10KHz from calling frequency) W1AW will listen on 144.130 and
swap their Tx  Frequency from 144.140 MHz to 144.130 MHz upon receiving a call)

3. CQ F W1AW (Up 6 KHz from calling frequency) W1AW will listen on 144.146 and swap
their TxFrequency from 144.140 MHz to 5144.146 MHz upon receiving a call)

4. CQ 147 W1AW (Listening on 144.147MHz) W1AW will switch from 144.140 MHz to
144.147 MHz after receiving a call.
