that's really weird. can you get a capture of it (both transmissions) with an SDR?
yes of course, here is an archive with two transmissions from the URH hackrf-rfcat.zip
i see the format (complex16s), but what's the samplerate, or anything else i might need to pull these up in InSpectrum (or another tool you recommend)?
from initial glance, it looks like the capture on the chronos isn't as clean as the ys1 (specifically, there's no dead-space at the front), so any attempts to line up transmissions is nigh impossible. can you send one with dead space and possible pre-amble for both?
Hey Atlas,
here are two new dumps (now they captured with hackrf_transfer tool). Each dump contains three submissions - RFxmit(bytes.fromhex("aaaaaafc2d00002b00000000000156")) Hackrf_transfer was run before each RFxmit execution.
chronos:~/chronos$ hackrf_transfer -f 446156250 -w Receive wav file: HackRF_20240131_105929Z_446156kHz_IQ.wav call hackrf_set_sample_rate(10000000 Hz/10.000 MHz) call hackrf_set_hw_sync_mode(0) call hackrf_set_freq(446156250 Hz/446.156 MHz)
I hope this helps, have a nice day!
I have an LRS pager, with rfcat + yardstick one fw ver: 0606, also I have an Chronos Dongle with firmware 0631.
d.setMdmModulation(MOD_2FSK) d.setFreq(446156250) d.setMdmSyncMode(0) d.setMdmDeviatn(4800) d.setMdmDRate(625) d.setMaxPower() d.setEnableMdmManchester(1)
everything works fine with Yardstick, but the LRS pager does not accept a signal from Chronos Dongle with the same rfcat settings
