VHF on Hotspot
VHF on Hotspot
I have been using my GD77 Hotspot successfully on UHF.
Yesterday i tried to use it on VHF. It locks up and the PI dashboard (Pistar4.10 RC6) shows TX, but there is no transmission from network.
So today i updated to the latest FW. I can do one successful Parrot test on BM then it again locks up.
Is anyone else experiencing this when running VHF?

Re: VHF on Hotspot
There is no technical difference between VHF and UHF but there is a lockup issue when the hotspot has not been active for a while
The bug fix is still on the To Do list, but currently there are higher priority bugs

Re: VHF on Hotspot
Thanks fer the reply Roger.
I didn't think that there shud be any difference between Bands?
Understood about to do list.
It does seem to lock up almost straight after start up , but not on UHF

Re: VHF on Hotspot
Its strange its locking up.
But there are definitely some RF calibration things we need to resolve which seem to affect VHF more than UHF

Re: VHF on Hotspot
Hi all, for what it is worth my experience seems to be exactly the same as the OP, on VHF it appears to lock up almost immediately, the actual Pi "dashboard" seems to freeze showing the last station as though they were on continuous transmit, along with the red LED on the Pi illuminating.
I only set it up this evening so very early days. On UHF it seems to be quite "happy" relaying TG91 as I write this. The functionality is very impressive, thank you for the efforts in producing this. 73s David G0FVT

Which version of the firmware are you running
Re: VHF on Hotspot
Sorry, I have just downloaded a new OpenGD77 firmware (I suspect that the version I initially installed was out of date). The version I was running before needed the button below the PTT held in on power up, this one doesn't. I will see how I get on. I prefer to operate the Hotspot on the NOV section of 2m (146-147). I will give it another try, sorry if I have misled anyone.
Re: VHF on Hotspot
Hi,
Cheers.
You need to go into Options settings, and enable the hotspot there. You can choose between MMDVM and BlueDV support.g0fvt wrote: ↑Sat Jan 18, 2020 9:35 pmSorry, I have just downloaded a new OpenGD77 firmware (I suspect that the version I initially installed was out of date).

Thank you, for the information, I did not know those options were there! 73
Re: VHF on Hotspot
i changed to VHF from UHF and experienced the PI locking up
It turned out to be RF getting into the program cable
a few loops through a ferrite core fixed all my issues

edit : i run 1w into an external antenna
