Leantrx power #27

Closed G0MJW closed 6 years ago

G0MJW commented 6 years ago

Lean TRX has a power parameter (--power) but it isn't available on the DATV TX web settings.

unixpunk commented 6 years ago

Can you test each of these options and let me know which one seems to work better for you? SSH to the pluto but stay on the dvb tx page and stop the sdr:

sed -i 's/-4/89/' /www/cgi-bin/leantrx/dvbtx.cgi Then enable the SDR again and see how it looks.

Then run: sed -i 's/--power 89/--agc/' /www/cgi-bin/leantrx/dvbtx.cgi Then disable/enable the sdr and see how that option is instead.

They both look the same which is interesting. All -20dBm.

I found another issue causing a problem. I have found the only way to make this decode is to set the RRC Rejection to 0 rather than the default 10.

unixpunk commented 6 years ago

You can try to change --power to 0, that one might be the right option, then change it to 10 and see the difference. I don't know what the waterfall should look like but in testing mine, I see a drastic shape difference between power at 0 and at 10.

https://github.com/unixpunk/PlutoWeb/commit/c2ff4c9384173e24ba21a6bc9a169d55423272c1 Set power from -4 to 0 and rrc_rej from 10 to 0. Let me know if you're able to find the optimal settings and I'll change them in another update.zip.

@G0MJW I'll close this for now unless you have any other update/request related to changing command line options, etc. Thanks for the assist!

G0MJW commented 6 years ago

Sorry for the silence, I have been travelling and without email access for the last couple of weeks.

Was I supposed to be testing something?

No prob, just mean that if you wanted a different value here or other values in the cmd line changed, let me know in a new issue.
