Direct Injecting a Galaxy or Connex type

[scooter71nc]

Hey guys here is the direct injection mod for galaxy and connex type radios, such as 33,44,55,66,73,77,88,99,3300hp,genral lee and some others that use this board.
You will need the following: 1 - cap between 3uf - 10uf no more than 10uf. 1 - 1/4 mono jack chassis mount. 1 - on/on switch. wire and soldering stuff.

1. Drill and mount the switch and mono jack. 2. Locate and remove C191. 3. Solder + leg of cap in hole closest to middle of radio. 4. Solder A wire from - side of cap to center pin of on/on switch. 5. Solder a wire from one side of the switch to the other hole of C191. 6. Solder a wire from other side of switch to the + side of mono jack. 7. Solder - side of mono jack to board ground (you can solder to a can).

Ok if you are using a mylar style cap it doesn't matter which side of the cap you put to the board but just make sure it goes to the hole of C191 Closest to Middle of Radio. I used a Tantalum cap which has a +/- leg. Ok you will also need away of keying radio either a foot or hand switch or even a stock mic with audio wire unhooked. but these radios a 4 pin mic plugs so they are very easy to make a foot or hand switch. If you need any help with making a foot or hand switch please ask and I will help as much as I can. I will post a new post later with all my foot and hand designs for 4 and 5 pin radios. I hope this will help someone have fun and enjoy!!!
