Motorola CDM1550 LS+ are there 2 different models?

[Lee069]

Hi, thinking of purchasing a Motorola CDM1550 LS+ but see that some on ebay are advertised as 450MHz and others are 430MHz. But looking at the spec sheet it looks like the radio's do both anyway, is this true or are there two versions of this model?

Regards Lee.

403-470 and 450-512 i think are the UHF splits

Yes. There are several varieties of the CDM1550.

You have the various bands: Lo Band, VHF, UHF Lo (403 - 470), UHF Hi (450 - 520). Then you have the LS+ and non-LS+ models. The LS+ can do regular old conventional as well as LTR trunking, where as the non-LS+ does only conventional.

CDM1550 Model Numbers

This may help (it's from the Basic Service Manual). Check the full model number before you spend your money to make sure you get the features you want. If it's for work, you may want to be sure you get MDC. Good Luck

Depending on the model be advised that you may has little as 2 or 17 conventional frequencies. The LS+ was designed as a LTR trunked radio so little need for conventional. The best model can have as many as 160 conventional channels plus the trunking. I would check against the model chart listed here for a AAM25XXA9DP6 if you want both or DU8 if not.

Which one you choose really depends on what you are licensed for and what your future usage will be.

If you are using these for work, then pick whichever one covers the frequencies you are licensed for. There is the overlap, so that can be handy.

If you are using these for hobby use, like GMRS or Amateur, get the 430-470, as that will cover the 70 centimeter band as well as GMRS. Even if you don't have an amateur license now, you may decide to go that route in the future. The 430-470 split will be easier to sell to amateurs/hobbyists later on if you need to.

These can be taken slightly out of their intended bands, but only a bit, and it will vary from radio to radio where the VCO will unlock.

Good radios, I'm using VHF CDM's (750, 1250 and 1550's) for all my personal vehicles. I've got a few at work, too. I've picked up 750's for as low as $75 and 1550's for as low as $150.
