The XT511 can be powered with AA batteries, its internal rechargeable battery, a DC power supply, AC power supply, and the crank arm.  The XT511 can be powered with AA batteries, its internal rechargeable battery, a DC power supply, AC power supply**, and the crank arm.  <nowiki>**</nowiki> The [[AC_DC_Adapter_Reference#Midland_18-394|Midland 18-394 MODEL: U090030D]] AC adapter is rated 9 volts at 300ma.  It supplies enough current to charge the battery pack, operate the radio.  It will allow you to transmit at the low TX power setting.  It has insufficient current to allow for transmit at the high TX power setting.  An aftermarket 9v AC adapter is recommended with at least 1000mA rating or higher.''Update: It should be noted that the AC adapter does not power the radio directly.  I provides low current to charge the battery.  The radio cannot be operated directly from the AC adapter without battery installed.  Using a higher current adapter of the same voltage is irrelevant since the internal circuit within the transceiver is design only for charging.''[[File:MidlandBaseCampandFamilyofRadios.jpg]]== Microphone Mod ==This microphone is compatible with Midland XT18 XT20 XT511 XT511MO G-225 G-226 G-227.  [[File:Midland_XT511_Base_Camp_Two_Way_Radio_micmod.gif]]Modify the microphone for auto from the base speaker and mic from the hand mic.  There are 4 wires in the cord.  ----* Black - sleeve on the 3.5mm TS Phono Plug ~ SPEAKER ~ ground* Red - tip on the 3.5mm TS Phono Plug ~ SPEAKER----* White - tip on the 2.5mm [[TRS Phono Plug]] ~ MICROPHONE +* copper / not insulated - sleeve on the 2.5mm [[TRS Phono Plug]] ~ MICROPHONE -* The ring on the 2.5mm [[TRS Phono Plug]] is null----There's 2 strands of white string in the cord not to be confused with the single white wire.[[File:midlandxt511_trspinoutcolors.jpg]]Make the hand mic / speaker a mic only (like a CB radio): To disable the hand speaker part of the mic unit you may simply cut off and remove the 3.5mm TS Phono Plug.  Attempts at removing the entire connector and replacing with a single TRS by soldering may be met with difficulty.  The Midland microphone uses extremely cheap, thin [[Litz wire]].  It is difficult to make a good solder with this type of wire.  This type of wire is typically crimped, however, in this case it is so small and extremely difficult to work with all over a $5 cheapo mic it is not worth the trouble.  Just cut off the 3.5mm TS Phono Plug if you want a CB radio type mic, the sound output will continue to come from the main radio unit.  Buy a second hand mic / speaker if you change your mind and want to return to the combined functionality.
