Basic Set Up For PCS 1900

Hi all: I've been on and off trying to set up Osmocom-BB for quite a while now. I've tried using several Cxxx with no luck of being able to lock on to a cell. I shifted to Pirelli_dpl10 hoping to avoid configuration change required of dual-band phones to work with Osmocom-BB but no positive outcome. I'm using Sylvain testing branch with transmit enabled; create mobile config file with PCS1900 and GSM850 as the only bands to be supported. For US Motorola dual band phones c139 and c155, I modified the required section of the rffe file to support PCS1900; and for Pirelli, I made the recommended modification to UART option before being able to communicate with the device. I guess I did all what need to be done for preliminary setting. Layer1 load perfectly but mobile application never work. Sim reader worked perfectly; Sim information was read, mobile app used the previous PLMN information to start power measurement. I was able to get average power of -92dB with Pirelli but while still performing the scanning the result output repeatedly fix prim_pm.c file with value to be overwrite message. I guess the issue has to do with passing the right parameters to layer1 to perform ARFCN scanning in order to obtain power measurement of the available channels. I'm not really sure if there is need to modify any part of layer1 or Rita files before accurate measurement could be done for PCS1900. I'm not that deeply knowledgeable in GSM standard but I can still figure out what to do if any hint is given toward what need to be done before PCS1900 band will work with any osmocom-compatible phone. I know that some people have worked on PCS1900 and GSM850 but there is no information towards what need to be done in terms of specific file to hack to change default GSM900 and DCS1800 bands configurations to GSM850 and PCS1900. I am pretty much sure that If I were in Europe I would by now step up from trying to make Osmocom lock to a serving cell to the point studying the code to work for a specific purpose. I am using the project as part of thesis work to analyze the Um interface and to explain processes that occur between BTS and mobile station. I will so much appreciate it if anyone could be of any help. Thanks.
