Feature Requests / FT8900
« on: 2024-01-14, 18:31:48 »
Good morning,

I use an RR box with an FT8900 for a connection between Africa and Europe (average latency 90 ms).
The FT8900 seems to need very short timing between head and post. Any packet loss or transmission time that is too slow causes the display to micro-turn off.

Would it be possible to consider modifying the software to "compensate" for these problems?

Using the same mode (15) the FT 857 does not have this kind of problem.

Yes it's ok, i found the 8v last night (looking for over radio wiring).

Connection between this mic and the RCC are ok (i found a manual and the wiring diagram, i just had a red pin to modify).

I think the problem is on the remote site ... so i will have to wait some weeks (i'm in Guinea now).


I wanted to suggest to someone on the forum to take control of the station with a module RRC PC to check that the problem came from here , but i think it's impossible with ft857 TTL remote. So I will wait until end of December ;)

AV908 take a 8V (but i think it's for the up down button)

On witch pin goes the 8v from RRC please? -- I found the pin, but still no audio - I will ask a friend to verify if there is no problem with the red wire

Hello Mike,

Thanks for your fast answer.

I'm using an over Mic (AV908) witch i have tested before leaving the remote site (on the ft857).

Codec and strips seems ok (on the 2 site). I will ask a friend to change some of them on the remote site.

Hello,

I made a remote installation for my FT857D with version 7 board.

All is ok (remote head, receiving audio, ptt), but no ... tx audio.

Does anyone have an idea of what could be wrong?

I had a similar problem after an upgrade. Perhaps could you test this :
- change the settings of audio on the two units (eg if you have 11 change to 8),
- reboot the two units
- change to the old preset
- reboot the two units.

For me it was ok.

Today I change the radio unit (hardware 4) by an over (hardware 5) who works ok.
I detect a situation wich cause RTP timeout falling from 60 to 40 it's after rebooting the control unit while the control units is connecting the radio unit.

I'll wait the 2 days and says if the "connection failure" disapear.

Hi Mike,

I change the control unit. I replace an harware 4 by an hardware 5 but the no change occur.
I made some ping-t test and i haven't any connection failure (ping average is 2ms) when the audio stop.
Today i will change the radio unit (hardware 4 replaced by the hardware 5).
