General discussion forum / CW issue: first characters corrupted, then fine

« on: 2022-01-11, 22:15:38 »

Hi
I have the following issue with my remote TS-480:
when TXing in CW the first 1 or 2 characters are corrupted but then it works fine for the rest of the passage. Next passage, again: first 1 or 2 characters corrupted, then fine.
I am able to test the behaviour only in 80m, where I can RX my own signal on the control site but other OMs on the radio site have confirmed the issue on other bands too.
I would  almost certainly exclude an RFI issue and I would rather say it has to do with some buffer but I have already set buffer size, jitter and delays to the max value almost

I have the following settings:

Control Site (cable connection):
Rx jitter buffer size   16
Rx jitter delay   15
Audio packet size (ms)   40
RTP tx mode   1
....
UDP cmd min-data-size   10
....
Lf delay ms [0-500]   400
Key delay ms [0-250]   200

Radio Site (WiFi connection to fiber router):
Rx jitter buffer size   16
Rx jitter delay   15
Audio packet size (ms)   40
RTP tx mode   1
Disable audio tones   0

The typical ping time is 50ms

Even if annoying, I can still live with this issue in normal QSOs but it is almost impossible to work DX stations or contests.
I haven't been able to find any similar 3D in the forum. Any suggestion?

Hardware, Cabling, Installations / Keyer Issue: has my RRC a fault?

« on: 2020-12-28, 06:37:40 »

The internal keyer of my RRC seems to be faulty. It always generates dashes (or dots if the reverse option is selected) regardless of which paddle (left/right) is being pressed. A factory reset hasn't helped.  Since it was fine till now I rather suspect a hardware failure : is it any way to verify it?
I haven't tried to use the I/O plug yet, I am going to prepare a cable later on.

Configuration of Routers, Firewalls, etc / Reach the Radio over openVPN ?

« on: 2020-12-20, 08:37:54 »

Hi
Since at my remote location is almost impossible to get a public IP, I am trying to use a VPN service.
The IPstatico.org service offers to each user (over openVPN) a static IP and 32 ports that can be configured to be forwarded to the RRC.
I have configured the router to forward the ports assigned to me to the RRC ports, e.g.:
Static IP xxx.xxx.xxx.xxx: myport xxxx1 --> RRC Local IP: RRC port 80
Static IP xxx.xxx.xxx.xxx: myport xxxx2 --> RRC Local IP: RRC port 13000
Static IP xxx.xxx.xxx.xxx: myport xxxx3 --> RRC Local IP: RRC port 13001
Static IP xxx.xxx.xxx.xxx: myport xxxx4 --> RRC Local IP: RRC port 13002

Now I can infact reach the WEB interface from the outside.  Anyway, it seems the 2  RRCs cannot communicate to each other on  ports 13000-13002. In the Advenced settings (control side) I have indicated the static IP and the xxxc2-xxxx4 as  new SIP, RTP and DATA  ports but it doesn't work....

any idea?
