My SatGate !

When the International Space Station APRS/PACTET modes are active
I put my SatGate on. Apart from South Africa area!! my SatGate is the only station active over the entire Africa !!!



Yes it rely stations from Europe to APRS-IS.

WiSP hints #4 test TNC -RIG -PC keying line

After hardware wiring of the TNC Rig with the PC
do the following to test the Keying line.

GSC--> Tracking--> Run pass --> select satellite --> OK

MSPE window wll pop up ,If every thing is ok you wll notice the TNC
LEDs blink three time = TNC in KISS Mode.

If there is an error message check again the ports and TNC setup .

On MSPE click fill --> small window pop up for different requests.

Chose fill directory --> and click ok your rig suppose to transmit
a frame of packet.

Now Use other radio and listen to confirm the transmission is ok.

Wisp Hints #3 - Fast upload

Hints to make Wisp more faster to upload messages to satellite
especially for HO-68 satellite.

1st - Prepare fresh messages and delete any none uploaded messages.

2nd- Do not make Wisp busy by requesting Dir or reading a file.
on the other hand DO NOT make the satellite busy too.

( DO NOTHING ) Let Wisp Hear the satellite .
Wisp w'll do every thing automatically to upload your files.

This is very important step (advice) and I'll say it again !!
(DO NOTHING ) Just watch your screen and enjoy your hot tea
and let Wisp hear and talk with the satellite alone.

3rd-The above advice wll prevent collision of the packet data between
your station and satellite .So more faster handshake of data in less time.

4th-Prepare your message with short title.

5th- Write your message in shorthand style .

6th- No need for HUGE signatures .See below the cool Alan's post at AMSAT 28 Jun 2000

All,
I've noticed that there are some *huge* signatures on messages posted to the
sats. I'm all for telling people who you are and what you do. But I saw
one that had to be over 20 lines. It was more than the message. Isn't that
kinda wasted bandwidth? If there wasn't email or qrz.com, maybe I could see
it, but I'd think it would be better to place that stuff on a web page and
not *every* message.

More wisp hints #2 - Update keps

It was an old problem in Wisp to update the satellite database easy!

My solution
1- Deleting the old wisp keps file.
2- Update only the keps for the satellite you want to use.eg AO-51,GO-32,HO-68
No need for the other sats at database file.
3- Prepate the keps for the satellites you want to use in a Notepad text file.
4- Re-update database .




More Wisp hints

1- Do File Housekeeping and Directory maintenance.
2- Delete any partial upload file ! I notice HO-68 refuse / deny the existence of any partial upload file on its BBS.
3- Use the faster PC you have.
4-IMHO - XP is the best OS for Wisp!
5-Many friends asked me about Wisp's setup -see photos pse

6 messages uploaded & more Wisp info

I succeeded to uploaded 6 messages today (20-03-2010)
to Hope-1 BBS.

My plan was to upload 13 messages!!
Yes I did the math and many tests for this acording to satellite pass.

Unfortunately the FM ruin my all week plan!! (For sure an unintended QRM ).

Anyhow the following photos show more info
about Wisp and the amount of data it can handling
according to pass time etc.


Tnx dk3wn for download hope-1 Dir






It works! thank you guys

It works! Today we had only ONE russian station who called CQ. I am very surprised – thank you guys for your discipline and tolerance for digital modes! Next week is scheduled again for voice operations…
EA1JM, ST2NH, UR4LRH, DK3WN were active today.

XW-1 Changes to the Directory

HO-68 Directory
Orbit # 1,232
1904:1924 UTC

Only 3 files uploaded today from Japan
No other file from the brevious 4 days!!
None of mine on the BBS !!! :-(

May be the switching of transponder on and off has a role
in delete the whole week (5 days) uploaded messages.

Where my pul file # 161 gone? And where my uploaded file # 160

At HO-68 Orbit #1205 Wisp started to upload a file number 161
The file 161 partial uploaded .on the next pass orbit # 1206 wisp try to upload what left from the file but the sever on satellite denied existance of file # 161 !!
and shift to upload the next file #162 (see 2nd photo)

Again the Directory was empty ??? I uploaded 2 or 3 messages yesterday and 1 messages
today file # 160 . As you can see in the photo #2 .The satellite
was accepted the file.

I requested the directory as my friend Mike DK3WN did !but it was empty! see this on the 3rd photo . where the Multipsk on other PC monitoring the Hope-1 satellite downlink by soundcard.

This question I 've asked several time !
is there something wrong on HO-68 BBS??

Again some stations FMing and QRMing the Digi Week !!!

FM QRM on Digital HO-68 week schedule !!

For 1st time I enjoy the 1st 5 minutes of HO-68 on Pacsat Mode
uploaded few Messages then the FM QRM took over the rest of the pass

For sure they do not knew the new regulation !!

This Regulation need more QST .

FM & Digital mode split sharing on Hope-1

Hello all,

I got a lot of responses about problem of digital mode
through HO-68. The main problem is that Packet communication
is often interrupted by voice. We are trying a new schedule
in this week, voice and packet operations will be separated
by the schedule, of course, this just depends on the hams'own
discipline. If you have any comment and suggestion, please
let me know.

Are you interested to collect telemetry?

Here is a short overview what you can actually hear if you are interested in
to collect telemetry:

OSCAR IO-26----------- 1k2 BPSK, sporadic 5 bursts
Fuji OSCAR FO-29---------- CW
AMRAD OSCAR AO-27---------- 1k2 AFSK scheduled
GURWIN OSCAR GO-32---------- 9k6 FSK 1 burst every 30 sec
(weak)
NavSat OSCAR 44---------- 1k2 AFSK only in sunlight 1 burst
every 1 min
AMSAT OSCAR-E AO-51---------- 9k6 FSK scheduled
KKS-1---------- CW
STARS (Mother)---------- CW
PRISM---------- CW
HOPE OSCAR HO-68---------- CW
CubeSat OSCAR CO-57 (XI-IV)---------- CW
CubeSat OSCAR CO-58 (XI-V)---------- CW
CUBESAT OSCAR CO-55 (CUTE-I)---------- CW
CUBESAT OSCAR CO-65 (CUTE1.7+APD II)---------- CW
COMPASS-1---------- CW beacon every 4 min
SEEDS---------- CW
DELFI-C3---------- 1k2 BPSK only in sunlight
SwissCube---------- CW
RS-22---------- CW
RS-30---------- CW
GeneSat-1---------- 1k2 AFSK

You can see - it's the best way to start with CW satellites. The most of
them are sending telemetry continuously.

The project has received major initial funding from the Radio Communications Foundation (RCF) and is being developed in collaboration with ISIS-Innovative Solutions in Space BV.

FUNcube is an educational single cubesat project with the goal of enthusing and educating young people about radio, space, physics and electronics.

It will support the educational Science, Technology, Engineering and Maths (STEM) initiatives and provide an additional resource for the GB4FUN Mobile Communications Centre.

The professionals weren't the only people listening !

The professionals weren't the only people listening to our signal though - amateur radio operator Bertrand Pinel (F5PL) from near Castelnaudary, France, used his 3.5m dish throughout the flyby to listen to the signal from Mars Express.

This Receiver is not deaf on satellite !!

With more than 33 meters coax cable 9913.
and 4 meters RG58 divided to 2 meters on each end (at antenna and in the shack ).
Plus many connectors with adapters and without UHF PreAmp!

HRD drive my IC-R20 Receiver so smoothly In a low elevation pass to received Hope-1 cw telemetry so clearly and with out Doppler effect.

Who said this receiver is deaf on satellite?

hardware TNC.This time I used Wisp with Multipsk
Both software connected via virtual port

Wisp read very well from Multipsk.
Multipsk keying the Rig with Wisp Rquesting.
Upload window pop twice but no msg uploaded ? QRM.!!

A buffer-like hold the Wisp reading packet from Multipsk
1st time. Shut MSPE and restart a new GSC solve this!!!
