Modifications for the ICOM - RogerK

Now power on and type in the frequency coverage as request, for the VHF and the UHF. Above I alredy mentioned the sureworking frequencies.To power on the transponder old the BAND and SET botton for two seconds.Same operation is required to disable it.6. Make same operation as point 1 and 2 if not yet ready.7. Unplug the two flat cables. Be kindly !!! And use appropriate tool to open the plugs.8. Unscrew the LOGIC UNIT (4 screws) and unplug it.Take off from the back all the screws around the antenna cables Take off the screws on the metal plates to cover the highpower section on both sides.9. Make free the 8 soldered pins with a solder and the tools that you prefer for this operation, located near the VCO Unit onMAIN B.Make free the pin near the power cable (+) and the pin near the antenna cable (hot). Pratically you have 10 pass troughtpins to desolder.10. Unscrew all the screws on the MAIN A and MAIN B boars and remove them from the aluminum block. Unplug the back fanfrom MAIN A board.EASY ??? Now is all open !!!11. Solder a shield-cable on PIN 2 of J2 of VCO B for the TX Audio on UHFSolder a shield-cable on PIN 2 of J2 of VCO B for the TX Audio on VHFChoose the smaller cable that you can have for this !!! You just have a little bit of distance. A good idea is to apply acapacitor to filter the signals (100.000 pF usually is good).12. Place back the MAIN A and MAIN B board. If you're lucky positioning your cables will be easy. But be careful, because youmusn't damage the cables. Use teh right screws and solder the 10 PINs.13. Place back the LOGIC UNIT with the right screws and work on it !Solder a shield-cable on PIN 11 of J2 for UHF RX AudioSolder a shield-cable on PIN 14 of J3 for VHF RX AudioIt's always good place the capicitors on this connections.14. Place back the front panel flat cables and the panel too.If you like you can place a wire for the PTT signal directly inside your RTX and than follow the hole in the back where youplace the 900 MHz antenna to have all the cables outside. Replace the back fan plug. Replace back all the screws on yourtable and remeber to plug-in the speaker plug before to replace the two covers.EASY !!!! Now if you done a good job all it's running ....but check your watch ... you spent here one day and your wife is still waiting for you to make shopping.You can test your RIG tommorow !!! Will be better !!!I hope that you'll be lucky.73'sss de Flavio IK2XYU or KF6EEZ !!!For other infos, send me a message:ik2xyu@ik2hdg.ilom.ita.eu (packet) or fcimardi@vnet.ibm.com (Int.Email)ik2xyu@it.ibm.comThis modification is read 713 times.top of page25-10-2000(IC-3230) IC-3230 repeater functionAuthor: Jon L - k4iiiIf you look at the IC-3220 repeater mod on this site, you will find a mod that will also work with the IC-3230.It states that holding down the "set" and "band" buttons for a couple of seconds will cause the 2 "L's" to blink.This will place the Icom 3230 into crossband repeater mode just as it does with the IC-3220.I tried this and it works with my IC-3230. I'm not sure whether it is stated in the 3230 manual since it is so large and I did notcome accross it.This modification is read 702 times.top of page
