XTL1500 800 Patch to Icom F5021

[jayhawkfirearms]

I'm looking to patch our Fire Departments 800 to our VHF frequencies as we don't have enough 800 radios at this time, 100% volunteer. I have access to Icom software, but don't to the Motorola software so I can't use our PM400 as I can't turn on the Pin 8 COS.

So I have a F5021 and would like to hook a OPC-1939 to it and make it do the same as the PM400. This should be possible I just don't know the pin outs and the solder modifications if any. Below is the motorola pin outs to make the system work, can some one match these up on the OPC-1939 diagram and tell me any modifications that need to be done to the radio.

XTL to CM200
Pin 13 ACT to pin 3 PTT
Pin 21 RX to pin 2 MIC
Pin 14 GRD to pin 7 GRD

CM200 to XTL 1500
Pin 11 RX to pin 23 MIC
Pin 8 COS to pin 16 PTT

The 5021 requires not only programming but soldering of pads on the board...

But here you go

XTL to ICOM
Pin 13 ACT to pin 14 PTT
Pin 21 RX to pin 13 AUX AF - Need to verify voltage levels
Pin 14 GRD to pin 1/8/12 GRD

ICOM to XTL 1500
Pin 2 RX to pin 23 MIC
Pin 4 COS to pin 16 PTT

The ICOM does programming alot different and is normally a bit trickier to interface. I think the biggest issue will be audio settings. All my ICOMS go thru a RICK device that allows me to adjust audio. Back to back with other brands does not normally go simple like MSI back to back stuff. When soldering the beads on the board dont use a large iron or you will damage the circuit board.

In the end if you dont know what your doing you should just take this to a radio shop and have them build it. Also remember there needs to be permissions to use the 800 in this mode. Have you talked to the system manager and gotten approval to do what your doing ?

Yes we have talk to the system manager, I have the tools to do this as we own an electronics repair shop so the small soldier iron isn’t a problem. Do you recall which pads by chance?

Did you not read the document that you shared. It shows what pads get soldered for what items.

I overlooked it, sorry for my mistake.
