WiSP "NO -5" Problem



● (No.972) WiSP "NO -5" Problem (2017年10月21日)
 -----------------------------------------------

WiSP によるディレクトリ要求の時に、衛星から "NO -5" という信号が返って
くる問題が生じているようです。自局ではこの問題は生じておらず、以下では
自局が的はずれな返答をしている場面もありますが、HW_VSP3, "NVT Enabled"
オプションを無効にすると解決するということです。

There seems to be a problem that the signal "NO -5" is returned from
the satellite at the time of directory request via WiSP. In my station
this problem does not occur, and in the following there is the scenes
where I, JE9PEL responded incorrectly. You will solve it if you have
un-check "NVT Enabled" option in HW_VSP3. Thanks for Edson, PY2SDR.

Hello Mineo,

Thank you for publishing the setup instructions for WiSP on your home page!
It was very helpful.

I am having an issue when trying to request the directory fill from
Falconsat-3. The satellite replies with a "NO -5 PY2SDR" response. I have
reset my directory file usong the GSC/Housekeeping/Directory Maintenance
menu, but it did not help. Have you seen the "NO -5" error with your setup?

Would it be possible for you to send me your "MSPE Dir Hiles.DAT" file?

Mineo-san,

Konban-wa.

Thanks you for the reply.

I am getting a "NO -5" error when requesting a directory fill. Presently I
have no messages to be uploaded. Since I have a fresh installation and no
directories yet, I thought the error could be related to the default dates
for the directory fill request. But even after resetting the directory
(removing holes and resetting the date). the error continues.

I found some very old message on the amsat-bb saying that the NO -5 error
was related to having the "smack" TNC checked on the TNC configuration. But
in my case, I don't have the smack TNC option checked. This weekend I will
try reading the pacsat protocol specifications and check the raw data being
sent to the satellite to see if the data being sent is correct. My
suspicion is that WiSP is not sending the correct request for some reason.

I will let you know if I make some progress.

[amsat-bb] WiSP on 64-bits Windows

Has anyone successfully requested directory fill from Falconsat-3 using
Windows 64-bits? It seems that WiSP sends a corrupt request to the
satellite on Windows 64-bits. I have tried running WiSP on two different
machines. Both with Windows 64-bits -- one running Windows 7 64-bits and
the other running  Windows 10 64-bits. On both, every time MSPE requests a
directory fill, I get a "NO -5 PY2SDR" response from the satellite. Roland
PY4ZBZ tried on his 32-bits Windows 10 system and the satellite replies
with a OK.

Comparing the directory fill request packet sent to the satellite by my
station and Roland's, it seems that, on my station, WiSP is corrupting the
directory hole pair data and also introducing one more byte to the request.

This is PY4ZBZ (good) request:

10 F4 00 42 8F E5 59 FF FF FF 7F 0D 0A

This is PY2SDR (bad) request:

10 F4 00 BF 12 E0 59 FF FF FF FF FF FF 7F

Thank you to everyone that has contacted me privately.

Last night I installed Windows 7 32-bits and WiSP on a virtual machine and
to my surprise, the problem I have been having persisted. After a lot of
hair pulling (not much left anyway) and investigation, I found that the
culprit was neither Windows nor WiSP. It was the serial to TCP bridge HW
VSP software. If the NVT option of HW VSP is enabled, it inserts some
control data in the data stream when it finds some pattern on the input
data stream. In the case of a dir fill, it was introducing three 0xFF bytes
right in middle of the KISS frame. This was being sent over AX.25 to
Falconsat-3 and was the cause of the "NO -5" error.

I've tested requesting a dir fill during the last pass here and Falconsat-3
replied with a nice "OK PY2SDR"! Now let's grab some headers and try to
upload a small file.

Thank you so much for chasing this down!

Last night was my first attempt to use WiSP with a transmit-enabled radio
setup and I also got the "NO -5" errors.  But not fully understanding WiSP,
I did not know what that might be about.

I have un-checked the "NVT Enabled" option and will look forward to trying
again on the next pass!

Edson,

Congratulations on receiving a confirmation on the WiSP BB!

I would like to abandon my hardware TNC and use your successful approach.
Can you let me know what SoundModem software your using as KISS TNC and what
interface are you using to key the transmitter.  I have WiSP, HS Soundmodem
and HW VSP installed.  I'm using an IC-910, thank you for your help.
