The new code for the sdr module is working sometimes but not always (#27)

We were putting in a 1 MHz signal mixed with a 1.1 MHz signal into both sides of KH3202 tunable filter on rack in UG lab. On the left side, we saw no suppression of the 2.1 MHz signal when setting the filter to LPF x10k with the dial set to 100 Hz (nominally, a 1 MHz LPF). The right side did just fine with switches in the same position.

Seems to shut itself off and won't reboot without a power cycle. Goes about 15 minutes before next failure.

ARP 1/30/18

Some groups are getting ~200 bogus samples at start of data capture. should test picoserver to see if this is the fault of capture code or is something deeper in the picosampler

The PTS 200 Synthesizer (the one on the left-most rack) currently changes amplitude drastically for certain frequency knob positions. 10 MHz seems particularly bad. The problem is probably a faulty contact in the switch that the knob controls.

Conduit interface has broken off. There was a bunch of water in it that broke observing. Resoldered power onto amp (which was underwater). Should probably replace amp, use heatshrink around wiring, and fix conduit.

Running pip install ugradio_code doesn't automatically install scipy or rtlsdr
