20-02-1999(IC-W32) Crossband repeater and extended RX/TX modsMods for the IC-W32E tranciver by SM6VIT Rickard. 970703The IC-W32E tranciver is a funny little radio that can do alot more than it does when it leaves the factory.On my radio i have RX on these FQs:AM 108-136MHzFM 136-200MHz300-400MHz400-600MHz600-1000MHzNow these are the FQs that is shown in the display so if U got a FQ far away from ham bands that dont work that is OK. I haventtested the sensitivity on different FQs so that is for U to do.Now to the really fun part, the TX FQ can be these:FM 108-136MHz136-196MHz362-400MHz400-492MHzThe further away from ham FQs U use the lower the output power will be.And remember that your antenna might not be built for all these FQs.To use extended RX FQs U have to do like this.While pushing [SQL] and [BAND] turn on power.It is as easy as that at least on my radio. This can be diffrent on some radios that are sold in contrys where it is illegal to listento other than ham FQs.WARNING! WARNING! WARNING! WARNING! WARNING! WARNING!Your warranty may be expired if U take your radio to pices!And most likly it is illigal to have a TX expanded radio in your contry!For the TX expantion it is a little bit more dificult. U have to solder in your radio.First U have to remove D523 (4) on the logic unit.Remove battery, remove 6 screws on the metal plate under the battery, lift up the metal plate and there is the logic unit.It shoult look someting like this._____________________________|_ic341 |ic201O_|o |1 5|2 3 |__4 | __|__ic5 | |diode|flat cabel o O | |_____|HHHHHHHHHHHH _| | |______________________________|1=D528, 2=D52, 3=D525, 4=D523, 5=D531All diodes have 3 legs!Then push for RX expand.Crossband repeater function is possible on the IC-W32E but it dosent work on my radio. It depends on witch CPU U have. But U
