Joe, Don't be too hard on Motorola. The Professional Series VHF-K handhelds (HT750, HT1250, HT1550) operate 136-174 MHz out of the box, and the UHF-R handhelds operate 403-470 MHz out of the box. These operate over the complete 2m and 70cm bands, respectively, as well as the commercial bands, without any tuning or hacking required. The Professional Series mobiles (CDM750, CDM1250, CDM1550) duplicate the same coverage as the handhelds.
I would like to be able to use a CDM mobile radio on 6m, but that is not possible. The low-band "D" split CDM radio will cover 42-50 MHz very well, but it cannot be programmed one Hz above 50.000 MHz. The interaction between the CPS software, the loaded firmware, and the masked CPU prevents hacking the radio out of band. In this respect, the low-band CDM and HT radios are not Ham friendly. However, I have a Motorola MaxTrac low-band mobile that covers 50-54 MHz very well. My VHF and UHF conventional base stations are a CDM1550-LS and a CDM1550-LS+, respectively, and they have given me reliable service. The ability to mute quietly (without a squelch crash) while receiving a signal from a non-Motorola system is one of the premium features of the Professional Series. [It's called "non-standard reverse burst"] Obligatory disclaimer: I'm not a Motorola dealer, and I don't have any financial interest in the company. 73, Eric Lemmon WB6FLY -----Original Message----- From: [email protected] [mailto:[EMAIL PROTECTED] On Behalf Of mch Sent: Tuesday, March 21, 2006 8:15 PM To: [email protected] Subject: Re: [Repeater-Builder] MTR 2000 It seems ALL of the newer Motorola units are not ham friendly.
