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

I was skeptical about this product; because I have purchased similar products in the past and they have not worked as advertised. This product works as advertised and I have used it many times with 100% reliability on VHF, UHF, 700MHz, 800MHz and 900MHz. .My reasons for not giving 5 stars are: - No customer service - I asked the seller a question and got no response. - I would like a setting that keeps the found frequency at least on the screen. 3-5 seconds. As soon as I release the PTT button on the transceiver microphone, the Anysecu SF-103 frequency disappears. See 6!/s/ Alfonso Faustino (K6ASF)
