Modifications for the ICOM - RogerK

Offset Freq: Hold [FUNC], Press [4], use [#] for up offset, [*] fordown offset, then enter freq to offset by (ie: [#] [0] [0][0] [0] [0] for no offset, [#] [0] [5] [0] [0] [0] for thestandard +5MHz UHF offset), [ENTER]Timeout Timer: Hold [FUNC], [8], Release [FUNC]Tx Inhibit: Hold [FUNC], [9], Release [FUNC]Special Channel Number: Hold [FUNC], Press [7], enter the specialchannel number (17-99), [ENTER], Release [FUNC]lData Transfer MASTER: Hold [FUNC], [BEEP], Release [FUNC]Data Transfer SLAVE: Hold [FUNC] with power off, turn on, release[FUNC]Helt to fint the U16 jumper>Questions:>>The file implies that the U16 must have a jumper in a certain spot, in>order for it to be user-programmable. Where should this jumper be?3/4 way down the left side of the logic board which is inside the front cover.>The file contradicts itself: when a new frequency is being inserted,>should it be entered as five or six digits?The frequency must be inserted in six digits. The decimal point must return to be a valid frequency entry. Also you must hold thefunction button while entering the frequency and then press enter before releasing the function buttion.Date: 07-01-2001 User comment From: DrewSubject: Extra infoThe mods for the Midland series 70-254A/B/C and -154 radios are the same as for the Icom IC-U16 series! Make sure thejumper on the BOTTOM of the logic board is removed before trying programming the unit.DrewDate: 21-07-2001 User comment From: Eric van de WeyerSubject: More infoJust a short note to let you know that THE ICOM IC-h16 is the VHF equivalent of the IC-U16 and programs the same way. TheMidland 70-154 is also the same as the IC-H16.Also, the Midland units call the FUNC button SHIFT. In either case it is the button closest to the top of the radio above the PTT.Date: 28-12-2001 User comment From: MichaelSubject: ICU-16 BatteryWould like to know where can i find a cheap place in California to buy a Battery for the ICU-16 radio mine isnt working at allThis modification is read 861 times.top of page19-07-1998(IC-U2AT) Extended TX mod for the Icom IC-u2ATThis mod will extend the transmit range of the u2AT from 139 Mhz to about 161 Mhz (further if you adjust the PLL). You'll beworking with a surface mount PCB, so you will need a fine point soldering iron and a very steady hand. And you will need onediode, like a 1N914, or a tinyier one if you can get it.You must have the service manual to help you identify where the new diode is to go. Review all the below with the manualbefore you reach for your scrwdriver and soldering iron!●●●●●remove the battery pack.remove 4 screws that hold the sliding guide that the battery pack mounts on. This is the piece of metal that frames the PLtone switches.remove the sliding guide. Be careful that you don't lose the battery release button.there's a screw on the left side of the HT just below the light switch. Remove it.CAREFULLY pry the front panel up. There's speaker wires AND a flexable lead that goes to the front panel.
