عدّاد لطيف ودقيق!
Muy bueno muy preciso y lo genial es que viene con batería integrada.
Measured it with calibrated test equipment (including a RF signal generator). Sensitivity could be better perhaps but it does pick up fairly low power signals. It needs a high threshold to register them, so close proximity is a must. Unfortunately the accuracy isn't that great... it's a good 0.5MHz off sometimes, which means a few channels off in standard spacings for VHF and UHF. This seems consistent across all the supported frequency range. Considering the test equipment is a 30k USD calibrated test set for CDMA... I trust my numbers. Build is nice, and battery lasts a while. It's a good value for the money, but don't expect extremely accurate readings.
Shortly said: Simple to use, fast and precise! Working like a charm on 2m and 70cm transceivers including the CTCSS frequencies! This little device helped us save a lot of time when trying to find out transceiver frequencies.
كل شيء على ما يرام، شكراً
