Review on 📶 Upgrade Version of SF401: Anysecu SF-103 A-SF103 Portable Frequency Counter (2MHz - 2.8GHz) for Two Way Radio by Fuzzhead Nelson

Accurate frequency counter in this price range gets 5 stars. It stably fixes the frequency within 0.001MHz and accurately detects sounds. The DMR functionality also works as expected. The user interface and manual aren't the best and they don't keep the latest frequency on the display; and for the price it's great. I've found that other browsers have had trouble stopping the feature and I suspect many simply rebooted and corrupted the device. Don't put the transmitter right next to the counter, I hold them at arm's length on either side of me and the readings are fine.
