Default XPR 6550 Radio

Pretty basic question. Do the XPR6550 need to be purchased in either VHF or UHF or can they do both?

They say they do:

Frequency range
VHF: 136-174 MHz. UHF: 403-470 MHz

Just not sure if there is a separate model for UHF or VHF.

Thanks

The XPR6550 are indeed separate radios for VHF and UHF, and in fact, the UHF come in two models, one that covers 403-470MHz, and one that covers 450-520MHz. The VHF version covers the entire VHF band.

So yes, if you want VHF and UHF XPR6550's, you'll need to buy two radios.

Or, you can spend the big bucks and get yourself an APX dual-band.

The APX does not do DMR

Since when? What do you think P25 / 7x is? Digital. Unless you're referring to a different DMR?

You mean it won't work with MotoTRBO. If they aren't doing connect plus or privacy plus, which are MotoTRBO features, then an APX will work just fine for Digital UHF/VHF.

An APX does the P25 flavour of digital. A TRBO radio does the DMR flavour of digital.

An APX will not talk to a TRBO radio.

The OP is asking about the XPR series of radio which is TRBO hence your "get an APX" comment is meaningless in this thread.

In some forms the APX and MotoTRBO radios will work together (ex: Conventional). It was a hypothetical statement. "Nothing in life is certain, except taxes and death." OP never made mention of using the Digital portion of the MotoTRBO... hence my response.

Sorry I strayed off topic.

They will talk to each other in analog mode ONLY. DMR and P25(including P25 2X TDMA and P25 phase 2TDMA) are completely different digital protocols. The only way an XPR radio can talk to an APX is in analog. Wether it is repeated or simplex. So yes asking about a XPR, I am going with the OP wanting to use it digitally rather than just analog.

Yup P25 IS digital, a protocol which was commissioned by APCO and is called Project25. MotoTRBO is DMR, also digital, but is a completely different protocol than P25.

Apples to oranges. I get it. No need to beat a dead horse.
