Uniden SMU250KTS Programming Software- Nabbed this radio at the local auction

[ectotel]

Nabbed this Uniden SMU250KTS at our local online auction for a few bucks with a nice benchtop power supply. Looking for info on the radio interface box and progamming software. I already have a DOS machine set up here iwth a real serial port if need be. Looks like a fun radio to to tinker with.

Thanks

The Uniden SMU250KTS was programmed using a Uniden AMX501 radio interface box, which used the mic connector as the connection. AMX501 interfaces are occasionally available on eBay, but the asking prices are usually quite high. Way more than the “few bucks” you paid for the radio. Currently two listed on eBay for around $150 !

Unfortunately, a more reasonably priced alternative had been offered through the RFGuys.com website for many years, but the owner passed away in recent years, and I think all operations have ceased.

I may be able to confirm the correct programming software within the week, if you still need that information.

Do you got any chance no where I can find a programming cable for the SMU 250 kts but I'm not seeing any on eBay just a clone cable

Anybody know where I can find a programming cable for Uniden SMU 250 kts eBay is not showing any at the time just a clone cable and I don't know anything about the interface boxes so have software but no program cable

As was said in Post 2 you need the AMX RIB Box. The cables are part of the box. And software will really only run on DOS with a true serial port and adapter cable.

Here is one on ebay but probably cost more than the radio at this point.

Yeah I've seen that one before but I don't understand the other Jack it's headphone jack but I have true Singapore and I'm not sure how I would connect that if I purchased and yeah I paid roughly $20 for the unit

One cable is for mobiles, the other is for portables.

Okay now that makes a lot of sense now thank you cuz it was looking confusing so I guess the back side of the box is where you plug in the rib cord for serial port thanks

Yes the DB25 goes to your serial port on the PC. You will most likely need a DB9 to DB25 adapter. They shipped with a cable with a DB9 on one end and DB25 on the other end. This was the improvement from the AMX500 which was a prom burner. With that when you got 16 channels in and typed the wrong number you started over from channel 1...was a joy to get actual software.
