Got this tweet from Exa. What is a 160Db station?
You need VIDEO transceiver on 910 with 25Mhz BW to hear and see it and at least 160dB gain, please confirm
I expect this means total amplification including the radio. Still nothing heard

Don't know about the 160 figure but given the very low power (for the 27 MHz B/W) of the CubeSat I'd guess it may mean a very high-gain antenna system and a low noise mast-head pre-amp is required.
There's another CubeSat due the use the 33cm band towards the end of the year - SkyCube - which will be deployed from the ISS. It has a 57.6 kbs downlink (the Boeing Corporation modem?) so bandwidth will be considerably less and may be easier to receive on low gain antennas.
