1  How can I set the power to low in the repeater mode
For better communication , we only set high power when in the repeater mode , may I ask why you want to set it to low power ? Do you use it this way frequently ? If so ,we could consider to add it on later production .

2  What programing cable do I use for the RT23? Where can I get one?
3  Where can I order a spare battery for the R23?
Because of the strict import and export policy,the
pure batteries could be only delivered to 16 countries
as below --
Austria, Switzerland, Czech Republic,
Denmark, Spain, France, Hungary, Ireland,
Netherlands, Norway, Poland, Portugal,
Slovakia, Luxembourg, Belgium, United Kingdom
4  Is this a true repeater. Can I place this at the top of a building and transmit from one radio below to another radio below?
It is can only as a cross-band reapeater , to make UHF talk to VHF .
5  The Software from the rt23 is a Option - Edit - The Option Edit is a Field - Parameter Adjust- Wat is the Passwort for thies Option -Parameter Adjust? MFG Hans
This is can only be used by Factory . Parameter Adjust is not for users .
6  I am trying to find the CHIRP programming software for the RT23. It works okay for the RT6 but RT23 is not listed.
Sorry but RT23 is in processing , these below are available models for now . We'll make it ok as soon as possible .
7  Which software do I use to program the RT23? Nothing on the CD that was sent has RT23. Only RT3,5,8 or 9000.
