Eco Levels

[VK3KYY]

OK.

I made a version where the C6000 DMR chip code, will not turn off the amplifier.

The FM code can turn it off but this should not happen in DMR

Hi,
since the morning (3 hours) I am testing this beta version D2021.02.16.01 - 39b0c5c.
Looks like this version of my GD77 1803A007xx series fixed a sound reception error. For me with this version it works on ECO LEVEL 0 - 4.
Do you want me to test another version?

That version does not disable the C6000 during power saving, so consumes about 28mA instead of 21mA (30% extra current)

Can you try this version

https://github.com/rogerclarkmelbourne/ ... _reset.zip

It uses the sleep function of the C6000 DMR chip, but every time I wake the chip, I do a full reset and reconfiguation of the C6000 (which takes 20 milliseconds)

But if you can test it, perhaps slowly I can determine which setting in the C6000 needs to be reset after sleeping

Note. That version takes a long time to respond to a signal probably 1 second, because it is constantly being reset during power saving

Hi, I downloaded the reset version at 10:50 am. On my GD77, it behaves stably at eco level 1 - 4. The signal and sound reception seems to be fine. The initial delay of about 1 second does not cause me to trim part of the session. The session is all from the beginning in most sessions.

It seems that the "Reset" version is the one that works best at the moment, 3 TG's open and the transmissions are received continuously without interruptions.

Hi all,

I am curious about Dual Watch while on an Eco level on the GD-77...

I had read on Github that when it is scanning there is no power saving, which makes sense of course... Though if memory serves me I remember reading something about DW being a clever function similar to scanning... So does the power saving take place during a dual watch?

In any case, thank you for the continuing hard work on this project, it's very much appreciated!

Hi Roger,

During the first tests, the reset version also seems to run stable for me.

Dual Watch operates as a 2 channel scan and thence does not allow the firmware to enter any form of power saving.

However when the initial bugs have been resolved, it may be possible to run at Eco Level 1 or 2 in Dual Watch by synchronising the scan frequency with the power saving duty cycle.

I don't know how the official firmware does Dual Watch during power saving.
I suspect it listens on each channel for half a second, so there would be some latency, especially on DMR, because in each half second window the Rx is only enabled for 120 milliseconds and this is not long enough to guarantee acquisition of a DMR signal.

Possibkiy some other system is used as the primary detection, prior to the FM detection phase, which is finally followed by the DMR detection.

So many more hours of R&D would be needed

Can you explain the 3 TG open ?

Are you receiving different TG on different TS.

Does the problem occur on Simplex ?

Is there any simple condition where the version from 13th Feb work OK?

OK

Perhaps not a complete reset is required, just some re-initialisation of the C6000 would be sufficient.

I will make another test version
