This Motorola CDM750 Low-band 4 channel Transceiver M25CKC9AA1AN is a reliable and versatile communication tool for professionals in need of a low band service. With a frequency range of 36-42 MHz, this transceiver is perfect for use in various industries, such as construction, transportation, and public safety. Equipped with PL and DPL features, this transceiver ensures clear and communication between users. The package includes the microphone and the radio.  I purchased this from a seller at a local ham swap meet,  the seller said it was a high split radio and would work on 6 Meters.  Unfortunately I did not check it until I got home and discovered it is actually a mid split radio 36 to 42 MHz.  My loss is your gain!
