Would someone please send Frank a 153-174MHz Orion to play with so he can figure this out?!?!! If I had one, I would! If someone out there has an Orion and the time they could figure it out in about an hour or so. You'll need the folowing: Calculator, DOS based Orion software, Orion radio -154-174 ...

Frank Seeing you've mastered the OOB for the MRK and the Orion uses the same software. It sounds like your plan would on Orions too! Fowler Actually, maybe not. I have not tried it on the Orion, I don't have one anymore. I did hear from someone who has tried it on an Orion and it seems the Orion ha...

You can find a manual for the UHF Orion here on our web site:

Thanks,

I have not tried it on an Orion but I'm guessing it would work the same way since the raw code is almost identical. Just be sure to read my post on this carefully and follow the instructions as described.

Frank

F.Y.I., I think I have Isolated this "Special Code" the program looks for before writing the radio. I am now working to make that special code accessable to the end user without doing the above described hex mode but for right now the above described method is the way to go. As soon as i h...

see my post on this, I've figured out how to do it....

Well, it's the weekend , the time to feel good and have a little fun! Here's the great news I had always wanted to deliver! I have determined the way to get those 150-174Mhz MRK'S on the ham band with NO HARDWARE CHANGE! That's right, who really wants to take a chance on screwing up their radio up b...

I want to ste up the channels to decode all digital traffic kind of like you could do with an Astro Saber. Does anyone know the defualt NAC code to decode all digital taffic??

Thanks,
Frank

Thanks, I finally gave up anyway and ripped the MTL controller out and put in a spare MPA controller.

Frank

I am attemoting to over write an MTL as a MPA and keep getting "Incorrect radio type" message, is there any way around this??

Frank

That may be, I am just happy the radio is working 440-470 mhz now.
Apparently the A1 Rf section is a hybrid that will work the entire spread 403-470 mhz, the old designation for the 470-500 Mhz deck was A5.
Either way , I am happy now and can use the radio!

Frank

Well I have now discovered that any "Switchable"MRK radio is just that- Switchable, as in band splits!! I had a 470-500 here that is now working great as a 440-470 mhz with no re-tuning!! I simply had to flash the controller to a 440-470 mhz split and now I am in business. One additional t...

These MRK's I picked up have a flash code of G30-3.01, I am guessing this is a very basic flash, does anyone know?? And what would be the most current flash version??

frank

I know the MPA's are pretty easy to re-tune for adjacent bandplits but can I re-tune this MRK for 440-470 mhz operation??? I was told that it has the same components as the 440-470 mhz , it just needs to be re-tuned, anyone have an opinion on this??


Frank

I have some MRK 2's that I may re-case as MRK 3 full keypad radios. I stopped in at the local PD hop, they use MRK 2's and had a few apart for service and it seems that everything is inside the MRK2 to upgrade it with a full keypad housing. Anyone know where I can get some at a resonable price??? Al...
