FAQ
Is this microphone compatible with my President radio?
It is compatible with all President CB and 10-meter radios equipped with a 6-pin round connector, including the Johnny II, Harry II Classic, Harry III, Taylor III ASC, Walker ASC, Johnson II ASC, Jackson II ASC, JFK II ASC, Lincoln II ASC, and many others. Verify that your radio uses an electret-type microphone before ordering.
Can I use this microphone instead of a dynamic microphone?
No. The DNC 520 U/D is an electret microphone. It must not replace a dynamic microphone (or vice versa), as the wiring and center-pin voltage supply differ. Refer to your President radio's documentation to confirm the required microphone type.
Do the Up/Down buttons work on all compatible models?
The Up/Down channel-switching function is active on most listed President models. However, some models such as the Grant II, Henry ASC Classic, or Lincoln II ASC accept the connector but without the active Up/Down function - communication remains possible, but channel changing via the microphone buttons will not work.
Does this microphone include a cable?
Yes, the microphone comes with its integrated coiled cable and 6-pin connector ready to plug directly into your President radio - no tools or adapters required.
