airspy의 sdr# 과는 다르지만 tag를 이용하면 band plan을 비슷하게 구현할 수 있을것 같다.

Connecting with compression A SSH tunnel does not only have the advantage that nobody can listen in on your transfers, but also another neat feature of SSH…. compression. To add compression to your connection just add a -C to the command which you use to connect with.
다만 3.2MSPS로 설정시 50Mbps 정도 대역폭을 잡아 먹으니 원격지라면 적당히 설정하고 써야 할 듯.
(1.8MSPS 에서는 30Mbps
1MSPS 에서는 17.5Mbps
0.25MSPS 에서는 4.5Mbps)
메뉴에서 source를 선택하고 "RTL-SDR TCP"를 고른후
상단의 톱니를 누르면 RTL-TCP Settings라고 뜨는데
여기에 호스트를 라즈베리 파이로 설정해주면 된다.
아무생각없이 rtl_tcp로 실행했으면 아래와 같이 뜨는데
소켓이 127.0.0.1 로 떠서 로컬에서만 붙일 수 있으니
