+ HOW TO “ZERO BEAT” CW SIGS - by Ed Ewell, K7DXV, Official
Observer, AEC Siskiyou and Modoc County ARES, and Official Emergency Station.
Here is a tip to help zero beat a CW signal that may be useful to others using
modern solid state rigs. These transceivers usually have a built in off
set on receive of 600, 700, 750 Hz, etc. and it can be difficult for new
operators to get on frequency. The method that I use with my TS440 Kenwood
transceiver is to switch to either upper or lower side band, zero beat the
carrier, and switch back to CW. If you follow this procedure you will be
on the same frequency as the station you wish to contact.
