tefbandscan's Issues

Add custom beeping to TEF firmware

For automatic logging, it would be nice to play a short melody or a different acoustic indicator, when the scanning restarts on the band begin

Get it running on a Chromebook

Get it running on a Chromebook (in Linux subsystem)

If possible, write a manual, how to setup a Hotspot on the Chromebook, to which the TEF can connect to, so that you don't to hassle with hotel WLANs, or when on a WLAN-free scanning area, you can still use the software.

If possible, configure the TEF Wifi connection parameters via serial cable

Integrate changes to Sjef's firmware

Users might not flash your patched firmware, so the idea is to integrate your changes into the main repository (Sjef), so that we will not have 2 parallel firmware repositories.

Partial log updates

Don't update a full log entry (and possibly degrade the logged data), but only update the "improved" fields on existing logs:

  • PI, when PI was only partially decoded (then we can allow PI codes with question marks again)
  • PS, when the error rate of the PS code (must be included in the log entries then) is lower and PS changed
  • RDS error rate, when decreased
  • CCI, when decreased
  • Signal strength, when increased
  • S/N ratio, when increased

Every time, the timestamp must be updated, too.

Prepare CSV for FMLIST import

Idea is to replace current FMLIST scanner, so prepare the csv for (automatic) upload to FMLIST.

to do:

  • integrate current GPS (and fallback to default, if not received)
  • add FMLIST user and password to config file
  • comments

S/N (SNR) value

If S/N is not shown (no idea why), don't mark it in red, but in grey or leave it.

It looks strange as the other values are ok.

In Webserver always show PS in preformatted text

If a station contains a leading space in the PS, this is logged, for example

"101100","5293"," FRECCIA","0","1","32","9","0","2024-06-05T18:29:54.843220135"
"102900","A213","  FM4   ","0","0","47","4","0","2024-06-05T18:30:04.281409742"

but not shown on the webserver.

Cannot kill a running session with CTRL+C

If the wifi connect is broken, but the script has started, you cannot stop it with Ctrl+C

Properly evaluate RDS errors

dec_error

[ 15:0 ] error code (determined by decoder)
[15:14] = A block error code
[13:12] = B block error code
[11:10] = C block error code
[9:8] = D block error code
0 : no error; block data was received with matching data and syndrome
1 : small error; possible 1 bit reception error detected; data is corrected
2 : large error; theoretical correctable error detected; data is corrected
3 : uncorrectable error; no data correction possible
[7:0] = reserved

Seems, like only the bits 15-8 (the first byte) is returned and must be evaluated properly (for PS, use only the relevant error code, not the whole number!)
