Motorola SP50 and MagOne programming question...
5/28/2012 2:37:56 PM
I'm trying to find out if this is even cost effective or not. Local group has a handful of 2, 10 and 8 channel radios with Wide band business frequencies. These have to be Narrow banded and they are business band and require a business license to use those frequencies before a local radio shop will even talk to them about narrow banding. They're not a commercial enterprise so they should have never been talked into these old business band radios. They're not going to all get Technician Class licenses for amateur use or the crappy GMRS bubble packs. I'm thinking MURS would be the best bet for them. On the ranch use while taking care of the horses for the most part and for their group outings once a week or maybe only twice a month.
Can these be programmed to MURS frequencies?
IF I can find the software does it really require old iron to run properly(386/486 processors).
Should I just tell this group to eBay the radios and pickup some HX370S that I can program for MURS use?
Thanks!

The SP50s work on MURS, the magone is a later product so they should unless there is some wacky firmware blocking it (and considering the intended customer base for the magone, I doubt that.
You won't need a 386/486, these are not Sabers/MT1000s from the 80/early 90s.
Remember the bandwidth for each channel. . Power limit is 2 watts.
151.820 MHz (11.25 kHz)
151.880 MHz (11.25 kHz)
151.940 MHz (11.25 kHz)
154.570 MHz (20.00 kHz)
154.600 MHz (20.00 kHz)
I know some will say that MURS radios must be certified specially for MURS use, but if you act in good faith (stay at or below 2 watts, obey the usual rules about being a dick, etc) then you should not have any issues.

Thank you for the response. I imagine I'm safe in assuming that the software will allow me to set both narrow band(MURS 1-3) and limit the output to 2 watts? I found the cable specification at Batlabs, but the screen shots of the hex dumps from the programming software weren't all that intuitive.

My experience with the SP50 was using one from 96-99, never programmed one so I can't say for sure if how the bandwidth/power can be set.

SP50's are NOT narrow band compliant.
Here is a list of Motorola radios that may still be in service that are not narrowband (12.5khz) capable:
Portables: CP100, GP300, GP350, HT50, HT600, HT90, MT1000, P100, P110, P200, P50, P50+, SP50, Saber

154.570 & 154.600 it is then 
I must have been thinking of the 1225 as being narrowband from that timeframe.

Thanks for that update mylt1.
If the local radio shop won't reprogram them to MURS 4 & 5 then I'm gonna steer them to the HX370S. That appears to be a sturdier radio than the current crop of Chinese handhelds.
