Midland STM1050B programming cable

Looking for a diagram to build a programming cable for a Midland STM1050B radio.

I know I have one, but just can't find it among all my stuff I have. Have a 15 x 20 storage area filled with shelving and a small path between everything. Boxes upon boxes and can't find the cable.

Re: any active EFJ users left?

It's been a while since there have been any post here. I am still using both the 5100 and 5300 radios. Have VHF and UHF versions. Not that much UHF activity where I am at, but the VHF activity is doing well. Have the radios set up for both public safety and some ham frequencies. They will do both wi...

5300 and rebanding to the 700 MHz segment

Can someone point me in the direction of some helpful comments? I am trying to see if I can get a 5300 mobile I have function in the 773 MHz range. The model number is 242-5477-201AFAB4. On power up it displays 3.17.21 and 4.6.6. Currently using version 2.10.2 software on the radio.

Re: trunking on ef johnson 5100

To the best of my knowledge, the software to generate an EFJ systems key has not leaked out of the company. Having been through obtaining a key from EFJ before, it is not that easy. You need to get the form emailed to you. Get the radio systems manager of the system you want to get the key for to si...

Re: 90 series out of band yet?

You have to get into the codeplug and hex edit each TX and RX channel location. You originally program the channel for 43.525 say if your looking to end up with 52.525. You then go in and hex edit the file. I someplace have a text document that gives all the information. Got it off the internet by d...

Re: trunking on ef johnson 5100

Even though you don't want to transmit, the software requires a key to be able to change any of the system settings. If you don't have a trunking system, you still will need to obtain a systems key in order to build the trunking system.

Re: 5300 Programming Nightmare

I have run into a couple of radios where I had to change the program data speed. One radio would only program at the lowest speed available. May not be the problem, but it might be worth a try.

Re: Astron RM-50M problem

I have also seen the output post short to the chassis. Sometimes they get over tightened and this causes the problem. It is easy to lift the wires from
these output terminals and see what happens.

5300 mobile - rebanding upgrade

Is there anyway to tell if the 5300 mobile can be rebanded in the 800 trunking or not?

The reason I ask is that I have a spread of radios where some were made in Waseca and others were made in Dallas.

Re: Orion Programming cable diagram

OK, found my diagram. Info for those that are still using the GE interface box, with a few mods to the programming cable, you can plug the cable directly into your serial port of your computer. Don't need the interface box for this radio any more. Jim DB37 - - - - - - - - - - - - BD9 2 120 ohm resis...

Orion Programming cable diagram

Does anyone have a PDF of the correct programming cable for an Orion? I believe that the one on the Hall site is missing a couple of resistors and a jumper to make it work.

I thought I had a diagram, but can't seem to locate it.

Re: MA-COM M7100

I am mistaken, the program cable uses the DB-37 connector on the back of the radio.

Anyone have that cable information to make a programming cable?
