  • EibiSpace B25 Stored DX Labels CSV file

    Well, no.

    First, this file is filled with dozens of illegal UTF-8 sequences. You can see the decoding failures in the browser's javascript console. They are mostly of the form e1 byte1 byte2, where the trailing two bytes are not valid UTF-8 continuation bytes beginning with the high-order bits 11. This is a symptom of improperly downloading files from eibispace.de. I had to learn this the hard way many years ago. You can't download files from there with the browser download function. You have to use wget plus some additional magic.

    Second, I don't understand why you'd want to do this. We already have an integrated EiBi database. Yes, it's A25. I've been waiting for B25 to be released. I don't think this csv file is the official B25 release as eibispace.de only shows a 27 Sept update to A25 as being current.

    The integrated EiBi database has a special filtering control panel that you don't get by uploading EiBi entries into the stored database. You lose that functionality which is important given that there are so many overlapping labels (more than 10 thousand).

    But whatever I suppose..

    All I got out of that thread was "82 year old codger" and "AI hallucinations", both of which I can relate to (lol).

    Actually I think I know what the problem is (amplitude imbalance). But I can't test until tomorrow.

  • Bad drift but ALL 12 CHANNELS GPS GOOD [check "Acquire if Kiwi busy?" checkbox]

    He mentioned in his email to me (but not in the post above) that it was set in continuous mode.

    Hi Ron. I think you must have checked "acquire if busy" because I now see "GPS acq yes" in the user control panel "Stat" tab with 3 users connected.

    One better way to assess frequency cal / drift than simply using zoom level 14 is to use the WSPR extension since it has an FFT display that has very good resolution. In the screenshot below I have set it to run on 30m. But tuned to a dial frequency of 14999.25 so that the time station carrier is in the middle of the display (200 Hz offset). Notice that it looks pretty good. Maybe just a tiny bit low. What's important is how stable that carrier is in the WSPR display over time with the GPS "good" sat count being a relatively large value (say larger than 4).

    Also, the backslash '\' key toggles which label database is being displayed. The name of which is shown in small white lettering in the top left corner of the frequency scale. Type 'h' to see a list of all shortcus keys.
