Hace 1 día · The SSB mode will cause the amp to delay unkeying for about a second in the absence of RF from your radio. So if the amp you are using doesn't have an SSB mode, you would have to add a delay circuit. Such a circuit requires a few components. A switch, an electrolytic capacitor and a resistor would probably do the job in most amps.
