[Skimmertalk] Red Pitaya Input 2

[Jan ok2zaw]

Hi Dan!

I do have the same problem at OL7M. When I run Spectrum analyzer, there is no sognal on IN1. PIC: http://www.ok2zaw.com/SDR/spectal.png  I used IN2 but still board was "unstable". I do have another one which works great!
I am sending the first one today back - I bought it directly on RP web. I think the best way is to write to support. 

Anyway, there is way to switch to IN2:

/sbin/discovery.sh

/opt/redpitaya/www/apps/sdr_receiver_hpsdr/start.sh

To select IN 2 for all six receivers you'll need to replace

sdr-receiver-hpsdr 1 1 1 1 1 1 &

with

sdr-receiver-hpsdr 2 2 2 2 2 2 &

I configured my Red Pitaya per all of the excellent guidelines on this reflector.  Thanks to all.  Everything was working great, but now I have a problem:

Something happened to the microSD card that came with my unit.   I bought a new microSD card and formatted it using the .97 image.  Everything appears to be working but no signals, and no waterfall on HPSDR, not even background noise, are present.

I tried loading the Spectrum Analyzer app and noticed that Input 1 was dead but Input 2 seemed to be OK.  I am assuming that something happened to Input 1!

Could someone tell me how to make Input 2 the primary receiver/antenna port?  I saw a Ubuntu script somewhere but can’t find it.

Has anyone else had this problem?  I bought the unit from Mouser and am going to contact them once I verify the problem.
