What makes this microphone so special. Well first off as many old timers now know Astatic stopped making nearly every high quality base mic they have ever made. The Astatic 878 is a good mic, but plain and simple. If your looking for something more advanced check out the JDC-201M. These mics are not sold through distributors. They are bought direct from the factory in big qtys.
What makes these mics special is the audio, and features. Notice the large meter on the mic. You can monitor your output as well as check for battery life. Also you can hook up two radios at once if you opt to purchase two mic cords. It has a PTT button, and a lock for the long winded QSO. For radios with up down channel buttons this mic supports that feature.
The cool thing is the mic comes with a compression module built in. High/Low or manual compression! Also you can select the mode for FM, or SSB. Great mic lots of features, low price! Buy your next great base mic at RadioActive Radios! Works great with all SuperWackPacked base stations! Qty discounts available.
