Ham Radio Deluxe as my satellite tracking/tuning software, and it would not operate more than one radio per I built this MAX232 interface box in 2012 to replace a single MAX232 box built in 2002. Lightly burn off the enamel coating from the wires before soldering.Īlso, note that you will have to remove the heat shrink from the Ipod cord and insert the plug quite far into the radio to reach the contacts (due to the recessed design of the speaker/mic jack). I solved this problem by using the 4 terminal plug from an old set of Ipod earbuds. Note that on Alinco mobile radios (such as the DR-735) that also use the ERW-7, the center pin of a 3-terminal 3.5mm plug is used, rather than a 4-terminal plug.Įlectrically, this cable is the same as the Yaesu VX5r, but a standard 4 pin 3.5mm connector does not fully insert into the Alinco. Besides the level converter, a steering diode is used, so that TxD and RxD can occupy the same pin. If you do not have access to a MAX232 chip, use the two NPN transistor plan (also on this page). You can build your own ERW-7 ERW-4C compatible cable for next to nothing with items you probably have laying around. I start with a bench grinder and finish with a file.Īfter purchasing my Alinco DJ-G29t, I was amazed to find out that Alinco expects you to buy not one, but TWO cables in order to program the radio! Combined, the cables cost nearly $100! The RJ45 connector must be ground down to fit the socket on theĮF Johnson radios. Kenwood TK760/TK762/TK860/TK862 Programmerįor the EF Johnson radio programming cable, I used a standard CAT5 cable with RJ45 connector on one end, and aġ/8" (3.5mm) stereo connector on the other end. This programmer will work on just about every Motorola mobile radio. Motorola Radius Maxtrac SM50 SM120 M120 M216 GM300 Programmer.

The Radio Shack transformers are unobtainium now, so I put together a full schematic soon along with the part list I used.

I like to use old PC monitor cables for this purpose, they are available and usually free! One monitorĬable typically has 3 shielded wires, up to 6 feet in length and about 6 stranded wires, and sometimes features ferrite cores that can be used for For theĪudio lines, I recommend using shielded wire.
This interface can be constructed for about $10, and will noticeably improve the audio on your Allstar node, both in transmit and receive. The idea here is to turn off transmitted PL tone only when my node is identifying. There are many things that the radio can be programmed to do when this pin is active, but I currently have the Motorola radio set In my case, the solid-state relay controls a DC cooling fan for my radio, while the other output connects directly to the Motorola 16 pinĪccessory connector. I designed one of the outputs with a 3 foot long wire lead to connect to a solid-state relay, while the other output connects to the Motorola 16-pinĬonnector.
Output to key our transistor, which can sink up to 200 mA! The solid-state relays I have require between 13-20 mA at 12 VDC. Instead, we are using the ARIusb fob GPIO
The GPIO outputs on the CM119 chip used in the ARIusbĪre only capable of sinking 8 mA, not enough for anything useful by itself. Transformers, bypass capacitors and a DC blocking capacitor which prevents the DC intended for the hand microphone from reaching the ARIusb.Īlso included are two NPN transistors which are connected to the ARIusb fob GPIO outputs 1 and 4. This simple interface consists of two audio This interface was designed in 2021 for use with theĪnd as built connects to the ARIusb on one side, and a Motorola 16-pin accessory connector on the other side.
