Hi Rich, Some quick analyse to start with.
US band 902 - 928 MHz range 26 MHz = 26,000 kHz EU band 868.0 - 868.6 MHz range 0.6 MHz = 600 kHz US frequencies are 501,000 Hz spreaded = 501 kHz EU frequencies are 6,000 to 27,000 Hz spreaded = 6 to 27 kHz Proposal for the testprogram. US step size: 80 kHz, total steps is 325, duration 135 s * 325 = 43,875 s = 12.2 h. May be the step size of 80kHz is too big to catch all channels, but with a step size of 10 kHz, the program will run for 4 days! EU step size: 2 kHz, total steps is 300, duration 17 s * 300 = 5100 s = 1.4 h. Testprogram need startfreq, endfreq and stepfreq as extra parameters In case we stopped half way, we can continue with a new startfreq, where we ended last time. Luc
