Retevis HA1UV vs WLN KD-C1

The KD-C1 is the clear winner for most users. The single most important differentiator is price: the KD-C1 costs 71% less than the HA1UV while delivering identical digital mode support and CHIRP compatibility. The HA1UV does not publish its TX power, making direct comparison impossible on that spec. The KD-C1 is lighter and costs significantly less, but the HA1UV offers an IP67 rating that the KD-C1 lacks. Owners report favorably on both, with the HA1UV at 4.6/5 from 47 reviews and the KD-C1 at 4.4/5 from 141 reviews; the KD-C1's larger review count suggests broader real-world use data. The HA1UV's weather sealing justifies its higher price only if environmental protection matters for your application. Buy the KD-C1 if budget and weight are your primary concerns. Buy the HA1UV if you need IP67 weather sealing and can justify the extra cost. The HA1UV's unknown power specification is a data gap that should be clarified before purchase.
