KevinRT73 And AntennaReviewed on Oct 20,2021i ordered while the on a holiday and theymailed as soon as they was back and they put up with me messaging then alot radio arrived quicker than expected radion came in 10 days and is well worth they money ive spent ive have had lots of good reports from friends well worth itJoeVery good DMR radio for mobile and stationary useReviewed on Oct 12,2021Really good transeiver to be in contact with mobile or stationary. The hardware is very stable, the software takes a bit of getting used to, but I think setting up a code plug for amateur radio is by and large not easy. However, the RT73 is easier to use than many other devices on the market. The feel of the device leaves nothing to be desired. The device is constantly being developed with new software. It is therefore important that you install new firmware and otherwise use the latest Retevis software. The dimensions are excellent, fits really well for installation in any car. The operation for mobile operation is also very good. The function keys can be adapted to all imaginable needs. I am happy with the purchase and would generally recommend the device to others!JenniferGreat mini mobile two way radio :DReviewed on Sep 27,2021Greetings from South Africa :D I recently installed my RT73 in my vehicle. Due to the compact size i was able to fin a spot to place my RT73. Works really well and thanks to regulour firmware releases the RT73 just keep getting better. I love it!Excelente equipamento!Reviewed in United States on Jun 05,2021Compacto, leve, prático de operar (com as teclas programáveis para acesso direto às principais funções...modo dual-watch (dupla escuta) e mista é excelente recurso (dica de Fabiano Costa (PU7ABC)! Para as próximas atualizações de firmware considerem incluir redução de potência para 1W (ou uma escala de 100mW até 1W) em lugar de Low Power (fixed) 5W - ficará perfeito para usuários de hotspot. Retevis acertou na mosca com o RT73. 73 de Crezivando (PP7CJ) - Maceió - Alagoas - BrazilRT73Reviewed in United States on May 18,2021Arrived in 10 days. Small in size, large in quality.Info su Rolling codeReviewed in United States on Jan 15,2021Buongiorno , vi domando che funzione ha il ROLLING CODE sul Retevis rt73 . Grazie per la risposta . Cordiali saluti De IK3DJB Ettore .Retevis rt 73Reviewed in United States on Jan 12,2021Order received in 15 days, everything perfect, order assistance always availableRetevis 73Reviewed in United States on Jan 12,2021received order in 15 days everything perfectVery good DRM radioReviewed in United States on Dec 28,2020Very good DRM radio, I hope there is a new firmware to improve it. Very good on mobile and base station Greetings from Catalonia EA3WZoran PetricRT73Reviewed in Bosnia and Herzegovina on Dec 28,2020Since a few days ago I became the owner of RT73. The first impression is good. The sensitivity measurements of the receiver are good. The output power of the transmitter is 5W less than I expected (20W)! I hope that other fellow radio amateurs will quickly realize that the total number of programmable keys includes 4 on the microphone, even though they are not numbered with P4..P7. :) I will check how the GPS works in the coming days. I am extremely satisfied with the visibility of the software and I think that even beginners will easily master it. It would also be useful to have a tool to import contacts and contact groups directly from the Internet. I will test the GPS later. All in all, the radio is easily installed in vehicles. I wish you a successful new year 2021. Zoran E73RS
