Review on Mcbazel Surecom SF-103 Handheld 2mHz -2.8GHz Walkie Talkie RF Counter: Efficient Communication Frequency Tracking Tool by Greg Lockhart

For the price this is perfect. As a radio amateur, I mostly check the frequency. What impressed me is that it will measure DMR (digital). If you need 10-12Hz accuracy or better, this isn't for you. For measurements that don't require accuracy in the 1Hz range (this device gets around +/- 500Hz), this is a good little meter. I used this to set up the radio input/output, DMR, to make my "open point" work more clearly.
