You need to define read commands for each, including calibration data, and then to add the commands to the POLLING line.
Pocket RxTx will read only S-meter when in Rx and only the selected meter (through a long press) in Tx (SWR, PWR,ALC or MOD), even if all are added to the POLLING line.
This does not help as some signals must be applied to test meters. The Monitoring function in jAReC 2 is the best way to test READ commands and validate your config (including calibration data).I even can provide you direct access to my tranceiver , if that helps.
Unfortunately I'm very busy at the office this week with no time to work on the configs.
