Yes it depends on how the alert is created. When using some tools, all kinds of combinations of modes and bands are feasible. But I thought the website is a lot more particular about the format, hence my question. I think that’s what is happening in this case, the editing built into the website interface is rejecting the data for an unstated reason, and date, time, freq/mode,comments are all possible problem areas.
I used to be able to type all my bands and modes into the band field on the IOS app Sotagoat, then add the final mode to the mode field. But in the current version of that software, entering the data in that way results in a frequency/mode string looking like 7.028-cw.7.090-ssb which does not comply with the format the web site enforces. The app sends its data into the website by a virtual back door and is not subject to the same editing as the online “form” used to post new alerts.
Anyway, I just thought that the format of the data in the band/mode field might be the problem.
