As New, original owner, DOSY inline Frequency Counter Ham/CB. 500 Watts 0.5 to 50 MHz
The Dosy FC50 is a 6 digit external frequency counter with blue LED’s and an on/off switch. On the rear of the unit are two SO-239 connections for coax (one IN “from the radio” and one OUT ”to the antenna”). The frequency counter is powered by a small wall wart that comes with the frequency counter for use in the home or it can be powered in a vehicle as it runs on 12vDC.
This unit is rated for 500 watts and I did confirm with Dosy that the rating is for 500 watts continuous.
