We recommend any handheld UHF receiver capable of tuning into the 400MHz-700MHz range, this is a standard range in most UHF receivers. Our recommended handheld receiver is a Baofeng UV-5R. Your transmitter will arrive with its specific Tx/Rx frequency noted on its back.
TINYTX's transmitters are easily paired with any compact hand-held transceiver. Any Two-Way UHF Radio will work, but we recommend the BaoFeng UV-5R from FengBros. Fengbros has been our trusted supplier for the last year, they offer certified Baofeng radios at the most competitive price.
