General discussion forum / DDNS update failed. Error 19
« on: 2023-10-08, 04:56:50 »
Like earlier indicated, I have difficulties in getting the DDNS to update the IP.

On the radio site, the IP has changed and External IP is OK
On the radio site, the Dynamic DNS status is  Error, Code 19

Other parameters
DNS Status OK, remoterig.com = 86.107.103.218

Where do I start looking  ?

General discussion forum / DDNS IP update failed

G'day,

I lost the connection to the radio site sometime yesterday. After pondering a while, I found that the remoterig DNS had not upadated my radio side IP. I edited it manually and it started to work. The update has been working ok until now, but the latest IP-renewal completely failed (luckily it does not happen that often . Is there a reason for that and is there something that may be wrong in my setup and I should pay attention to  ?

General discussion forum / SSB suddently dropped out

G'day,

Yesterday, practically in the middle of the qso, I lost the ssb transmitting audio completely. Reception works fine, PTT works ok (i.e the transmitter on the remote end is keyed), but no ssb audio at all (not even a faint noise on transmitted audio). CW is ok, FSK is ok, USB -audio (connected to a local computer) works ok but I cannot get the remote microphone audio until the DSP of the TS-590 SG.

As I am 7500 km away from the radio site, the troubleshooting is somewhat cumbersome but I am proceeding as follows:

The above tells me that:
1) the radio circuitry until the DSP is somewhat ok.
2) an unlikely possibility that may have failed in the radio end is the ADC (the codec) which is sampling the audio from the front panel mic connection but I am more inclined to believe that it would possibly be the radio end RRC.

Now, is there any practical means to remotely check the audio circuitry from the analogue side at remote site until the analogue audio circuit on the radio site, bearing in mind that the tools that I have access here to are in the range of screwdriver and hammer instead of anything more sophisticated ?
Has anyone seen this kind of a thing before ?

I can isolate the radio issue later this week when I get someone to the station to change the radio but I would like to test the remaining circuitry  a bit further as the only unit that I have not  yet doubled are the RRC -boxes.

Any advice would be more than welcome :)

I have a peculiar problem where the receive audio is sometimes lost but the transmit audio remains. What happens is that the I hear a "snap" and the receive audio disappears. Both transmit audio and cw key remain ok.

Following setup
RRC-1258 MkII on both ends, radio end directly hooked up to the router, remote end on wifi-connection as here in China the 4G-network seems to provide better stream. I have tried with different coding, same thing.

It doesn't appear every day, not even every week but is very annoying when it happens in the middle of the qso. It seems to happen more often when the connection between Finland and China is good and does not happen when I have the usual problem which is the slow throughput.

Any ideas are welcome,

Ville oh1jd
