There is a new update to SDRUNO software at SDRPlay. There are also links there for the SDR Console V3.P7 software. Between the two of them you can decide which you like best for functionality and screens layout. The control software will have to be newer versions to handle the new hardware that is the SDRPlay RPS1a.

Sounds good. Can't knock the price for what you get. Any SDR over the $20 cost of the cheap RTL-SDR dongles is a huge improvement. I started with a dongle and soon realized it is very limited in receiving bands. Think you will be very happy with the RSP-1a.

SDRPlay RSP2

What are you ordering if I may ask?

Primary reason is that only GBT is steerable for our current antennas. Arecibo is not. You would have to coordinate observing campaigns at each antenna. Also, we don't have exclusive access to the target observation star, we normally just 'piggyback' on the nights primary science target and have our receivers and recorders listen in as secondary. I do believe that many of the radio telescopes DO in fact do long baseline interferometry of observing targets. With bringing on the steerable Parkes array in Australia in the future there should be candidates at the celestial equator visible at both GBT and Parkes. So we theoretically could do differential listening if the hardware is compatible.

Well, there are hundreds available on Ebay at the normal $20 dongle cost. Just search for RTL SDR on Google. I like my:
SDRPlay RSP2 receiver for $170

So all the SDR's that I am familiar with tune that band of frequencies. Most SDR's go to around 2 Ghz, some as high as 6 Ghz and then if you want to tune higher you just put a down-converter in front of the SDR receiver.
