Hi Rick
Well so far with the testing we are doing on RFSM8000
it appears to work very well -
below are some transfer figures from the program
using the Non-standard mode .3 to .2.7 khz wide application
band in not all that good of condition - freq 10137 usb path distance
approx 1000 plus klm s/n changing up and down quite dramatically
FIGURES BELOW ARE FOR THE FILE TRANSFER SIZE AND TIME TAKEN
