Hello! Just wondering if you installed a TCXO because the Purple MSI SDR does not have a temperature controlled crystal oscillator, even though it says it does?????
My variant of "purple PCB MSI SDR" had generic 20ppm crystal and wrong load capacitors, so I had to change it to a TCXO to improve LO frequency accuracy and stability.
@@vladisslav2011 WOW, 20 ppm is pretty bad! Good thing you have the skill to solder in the new one! I just purchased two MSI-SDR Blue Dolphin dongles and both crystal oscillators were not 0.5 ppm temperature controlled as was marked on the case!!!!
@@vladisslav2011 How did you know your XO was 20 ppm? I'm wondering how I can see what mine is. Is it the number on the oscillator or did you test it? Thanks!
@@danedewaard8215 I've just read the crystal marking... The real measured offset was ~17ppm on VHF/UHF and twice as much on HF. I've used HF time station (this video), GNNS satellites transmissions and 0.1ppm TCXO fundamental and overtones as reference signals.
