Problem activating repeater
Problem activating repeater
A couple of colleagues here in Spain have a problem with the GD77 which is not able to activate the repeater when there is no transmission.
When the carrier is activated, the equipment has no problem entering the repeater and synchronizing, but it is not capable of activating the transmission.
Any ideas ??

Re: Problem activating repeater
I think this occurs DMR only...
Well, If not receive transmission of the repeater, has not activation of PTT.
This is normal!
Maybe the repeater are not good adjusted¿? Is a MMDVM hardware or a Hytera?
I use my gd77 in a couple of repeaters and works fine.
I making a MMDVM repeater during this lockdown and I see is not a trivial adjust to make this working on DMR. Is very different as to make work in FM or C4FM... More critical. One time is well adjusted, el GD77 run perfectly.

Re: Problem activating repeater
This is most probably due to repeater not being adjusted ideally. I have two gd-77, one with opengd77 firmware and other with factory firmware. Opengd77 is much more sensitive to any loss on either TX or RX. I also have problem with opengd77 to sometimes enter local mmdvm repeater, which I never have with factory firmware. Also I have much more stuttering on opengd77 than on factory firmware. This all has to do with TX of the repeater, as I don't have any of these problems on my dual hat hotspot (which works the same as repeater). I also have several Baofengs (1701, dm-x) which don't have any problems on the same repeater. So, as developer state themselves, original gd77 firmware send much more data to processor, which somehow allows it to connect without problems to repeaters which are not tuned 100%. But if they were, you would not have these problems with OpenGD77.
Re: Problem activating repeater
I forgot to mention, they should try changing calibration settings (take care, they are separate for VHF and UHF). If you can't change the repeater tuning, you can try re-tuning the gd-77

Hi
I have this problem too.
I can't connect with this dmr repeaters, ED7ZAL (UHF, Hardware MMDVM (Repeater). Firmware 20170501)
With the oficial firmware, fine.
I commented my case in: 7 and 8 page

Re: Problem activating repeater
You can try the latest "Development" version
https://github.com/rogerclarkmelbourne/ ... /D20200507
I slightly increased the time between each retry when waking a repeater, (from 500mS to 600mS), because I found the official firmware uses 600mS

Re: Problem activating repeater
I just tried this version (20200507) but it has not changed me. The repeater does not wake up.VK3KYY wrote: ↑Sun May 10, 2020 11:20 amYou can try the latest "Development" version

Thanks
Re: Problem activating repeater
I modify the Wake time to 2500/5000 and appears that works with some repeaters
