SSB frequency

Post by redlght » Monday, 30 June 2014, 18:49 PM

I get asked a lot how to check SSB with an inline counter.
I use this method to see if radio is on frequency:
Set CB radio to 27.2050 Ch 20 27.2050
Inject a pure 1Khz tone at mic socket key the radio then your counter can read it at the antenna socket
You should see 27.2040 on LSB and 27.2060 on USB.

That is the way I've been doing it. Download a couple different tones from different sites, some do have a slight variation. I have 1kc and 440hz in the library. I use iTunes to play them and just hold the mic close to the computer speaker. At least it gets the radio in the ballpark.

I've used this as a quick test but are you using this method to align the radio?

By no means is it used as an alignment but like I said,

This way only does the transmit and is better than the "out of the box" 2 to 3kc off from the factory. To do the receive you have to have a good ear and listen to a known station that is on frequency to center up the clarifier. Nothing beats a proper alignment with real test equipment.
