I spotted myself on 5.298.5Mhz here in the UK and it spotted me as FM not USB (I didn’t notice).
The 5Mhz band in the UK is a few tiny slots of band we have to squeeze into around military operations.
A few times I’ve managed to pick an out of band frequency (by 0.5Khz) and luckily when I’ve spotted myself someone has messaged me saying I’m out of band.
Again inadvertently I’ve managed to activate on the SSTV frequency on 20m or in the CW portion.
So would it be possible to have a band plan database based on the operators callsign / and license class and the frequency come up in red / amber /green if it sees a clash or not allowed?
I appreciate band plans in the UK are just a gentleman’s agreement but it might save someones backside. In a similar manor I’ve spoken to general licensees in the wrong part of 20m so perhaps the option to add license class type.
I appreciate it is more work and I’m happy to do the leg work in the UK.

As far as the first issue you raise is concerned, I’m sure this is an easy fix.
As far as the rest of it, well you are correct in that it’s a lot of work and requires considerable modification to the interface as well. But I’m not sure that everyone would feel a need to register their license level into PoLo. I for one, would not feel this necessary. But it would be necessary to follow your suggestion. Also the different world authorities have quite different band plans so it would not be a small job to construct and then maintain the band plans of all areas. e.g. NZ has only this month been granted phone access to the 30m band. PoLo would be behind the times constantly in the face of regular changes. Once you construct the plan for the world, someone has to commit to maintaining it.
Sooner or later we amateurs need to take responsibility for our operations. After all, we, most of us, pass a regulations exam as part of the license.

Thanks for the reply Alan
I agree we need to take responsibility and understood on the interface update and maintaining databases, it was just an idea.
As a self help to the user could you have a local text file which was checked when the frequency was entered so the responsibility comes back on the end user.
As for an alert could it pop up in the same was as “Dup” and “New Band” pop up?

Also I noticed this when uploading to the Pota site and it’s logged 13 QSOs where I only made 11.

Bob,
When you make contacts with an OP in a 2fer or 3fer, PoLo records that one QSO as 1 QSO in your full Log. But to get credit for the other park 2 park contacts, PoLo creates as required, separate additional QSOs which are unique, in the POTA export file.
This is as per the requirements to get full credit.
AFA the missing band, this is a warning so there was no harm done. But again, this can and will be fixed in a future release.
Alan
Every day is a school day!
I have never noticed it previously as usually an activation is up in the 80 QSOs so didn’t stick out, I only noticed it today as conditions were very poor and very low numbers.
Thanks for sharing the information.
Bob
There would need to be a bit of thought put into this.
Firstly, the current PoLo band plan is a resource like other resources, embedded into PoLo at compile time. There is currently no mechanism for mobile apps to access external files which are outside their security “sandbox”. I assume you are thinking along the lines of how N1MM accesses external files. This is different.
Secondly, there is very little room in the user interface for further warnings. If you have a large device, you may see more space but the design must be suitable for small phone size devices as well.
In VK, I have advocated for all bandplan initiated mode switching be removed. OPs using PoLo in VK are totally at their own discretion as to what mode and what frequency they use. It’s their responsibility to operate without causing interference with others. There is a lot of support to maintain this approach here. I can’t speak for other jurisdictions.
