OpenGD77

Hi,

As far as checked, I've not been able to find a specific tread about this new features so, I've set this new topic...
Maybe a new branch under Discussions to be created ??

Anyway, here you have some proposals to improve the mode:

Date Entry Screen.

Shows like this:
Suggested showing like this:
It's not obvious to people not having English as natural "data format" to guess this.

Hi,

Another improve proposal:

Location Screen.

Shows like this: Suggested showing like this: It's not obvious how to set N/S nor E/W values...
I've been able to find... E/W value ABOVE 256E are changed to X-256 W, anyway it's crazy doing this way.


BTW:
What about refusing wrong values (same as done at frequency entry) ?
It now allows crazy values like these: More Northern than the North Pole and more Eastern than East...

The radio can't contain its own operating manual.

Ok...
Any way, filtering data entry is possible.

It does not make sense entries with LAT beyond 90 or LONG beyond 180.

Isn't it?

This is already fixed in the version that is with the pre-beta testers

However, the radio firmware is not intended to be "idiot proof", its designed for Ham radio operators who are presumed to have greater level of skill and knowledge from the general public.

Yep, I agree.

BTW.

See the latest beta. It attemps to prevent invalid date or location being entered. Its probably not 100% perfect, but then nothing is

Sep 10th...

I'll have a look.

Once more, thank you for this great job !!

The satellite and suspend modes are brilliant!

I tried with the ISS last night. It agreed with two other trackers within seconds. The RTC is remarkably accurate for using (I assume) a microprocessor clock.

RTC just uses the processor. The processor runs from a 12.288 Mhz crystal, but I don't think the crystal is super accurate.

The prediction accuracy seems to depend a lot on the keps, and the prediction algorithm which each program uses.

The firmware uses the original AMSAT calculation algorithm, written in 1983 (called PLAN 13).
There are newer prediction algorithms, but the PLAN 13 algorithm seems to be accurate and does not take too much space in ROM etc
