Exciting news! 8-band skimming is now available on the Red Pitaya.
Pavel Demin has released a new version of his Red Pitaya SDR software that
can support skimming on up to *8 bands simultaneously* at 192 kHz, making
it more powerful than the QS1R, which could only skim 7 bands. Prior to
now, his software could skim 6 bands at most.
Pavel has also restored his apps. to the Red Pitaya Application
Marketplace, so upgrading and installation is simple again:
Upgrade procedure for Ubuntu Linux users:
1. Terminate RTTY Skimmer Server, CW Skimmer Server, HDSDR, and the RBN
Aggregator so that nothing is using the SDR software
2. Open a web browser to your Red Pitaya's alias or IP address, e.g.
3. Click on the green *Application marketplace* icon
4. Scroll down to the bottom of the page
5. Click the *Upgrade* button underneath *SDR receiver compatible with
HPSDR (1.0-20171025)*. Make sure to Install or upgrade the SDR
*receiver*, not the SDR Transceiver.
6. *Do not *click RUN (this will require that you keep a browser open to
run the SDR, and we have better ways)
7. Close your web browser
8. Login in to a Red Pitaya command prompt with Putty and type:
(Advanced users may run
/opt/redpitaya/www/apps/sdr_receiver_hpsdr/stop.sh and then run the
edited /etc/rc.local to update the FPGA and restart with the new
receiver, instead of rebooting)
9. After 1 minute, the Red Pitaya will shutdown and restart cleanly
10. Restart Aggregator and everything should work as before. NO changes
required to other software such as CWSL_Tee or HermesIntf.dll; they already
support 8 bands.
11. Click on the *ini Files* tab of Aggregator
12. Click *Edit* and change *SegmenSel192* line in the selected ini file
to select up to 8 bands. Save the file and exit the editor
13. In the Aggregator, click the *Now* button next to the edited ini
file to stop and restart both CW and (optionally) RTTY Skimming on 8 bands.
Upgrade procedure for Alpine Linux
1. Go to https://github.com/pavel-demin/red-pitaya-notes/releases
3. Unzip to your *apps* directory on the Red Pitaya
4. Continue with step 8 above
These commands may also work, from an Alpine Linux command prompt (not
tested, each command is one a single line, though email may wrap them)
If you need a 14:1 transformer or two for your Red Pitaya, I still have a
few left in stock. Use http://www.kkn.net/~n6tv/XFMR to order.
