GE/Ericsson M-RK and Orion

Post by radio230 » Wed Mar 21, 2007 9:47 pm

Is there some kind of special relationship to the Orion mobile and the M-RK portable? I ask only because I looking to buy both of these radios, and in looking discovered they both use the same (old DOS)Programming software. I thought it strange that one program would work with a specific mobile and prtable radio, making me think they had some kind of special relation ship. If you know let me know.

I am also looking for any technical information about these radios, since I am trying to buy them, such as channel capacity, fetures, etc. I would be using them in an analog-conventional radio system. Any info you might have would be great. Thanks

The Orion and MRK radio share similar microprocessors. I suspect they are identical, but I have never actually checked. However, yes, you are correct in that the programming for the Orion and the MRK shares a common relationship. In fact, you can easily convert an MRK personality to an Orion one and vice versa.

Hall Electronics has a pretty comprehensive database for Orions and MRKs. I can never keep track of all the various combinations that were made, since they made multiple versions over the years (128,256, and 512K logic boards, w/n switchable, etc.) Also, even if the radios all have identical hardware, some radios may also be feature encrypted for additional options.

(For example, narrow band operation on an MRK not only requires a w/n switchable IF board, but also a feature encryption option).

If you are looking at purchasing MRKs or Orions, keep in mind that the earlier logic boards (128K and 256K) will only work up to a certain revision flash code and have a more limited channel and talkgroup capacity. The earlier radios will not do narrow-band operation, so if you need that capability, you will need to know the combination numbers of the radios before you buy them so that you can verify that they have the correct hardware to do that.

Thanks for the info!

I am actually looking to buy one of each and will need them to do a few narrowband channels. You, or anyone, would not by chance know what the correct combination number would be would you. I looked at the Hall Electronics page and it is a bit confusing to me. What I need for both the Orion and the M-RK is analog conventional operation, including some narrow band channels, in the high VHF band split (150-174 Mhz). I really don't need more than maybe 60 channels, and that is a high estimate.

Also, is the feature encryption hackable like on alot of Motorola stuff, or does it HAVE to be redone by a GE tech?

I don't know the correct combination number offhand, but both the MRK and Orion need to have a 512K n/w switchable logic/IF board. I've never tried to hack feature encryption string, nor have I ever heard of it being done..but since I work on Orions and MRK's commerically, it's never came up.

I'm only familiar with the issue because we had customers with earlier MRKs and Orions who wanted to switch over to narrow band...and while the radio took the programming for narrow band channels, the radio was still operating in wide-band mode.

Somewhere at work I have the info that I received from TAC about whether the hardware is narrow-band capable..I'll take a look for this week.

Hey Meatball...

Wouldn't happen to have the flash? files so that I can get a lowband and UHF radio to dual radio?

I forget off hand what the actual name of the file(s) is.
From the Federal Signal Price Book:
"Warning: Sirens and Speakers may produce LOUD sounds necessary to request the right-of-way."

Really...You think?
