Performance and practical notes :

Polmar's RX-5 model differs from other scanners by being aimed at those who do not have much experience in using receivers and who want to focus on the main VHF bands. This leads to a reduction in the number of parameters under control of the user, in fact a simplification in the use of the apparatus. It should be noted, however, that this characteristic proves or not an advantage according to the user's preferences.
