Thanx Scott
(WA6LIE)
and TSUP (Mission Control Center) for information.
Ham radio activity aboard the Mir space station came to a close on
August 28, 1999 as the crew returned to Earth, leaving the station
unmanned. Mir is in a stable orbit with only essential systems running.
All Amateur Radio activities have ceased.
Current Amateur Radio equipment aboard Mir includes:
MIR SAFEX II 70-cm Repeater
Uplink 435.750 MHz FM w/subaudible tone 141.3 Hz
Downlink 437.950 MHz FM
Not operational. No operation in 1999 or 2000 has been observed.
MIR SAFEX II 70-cm QSO Mode
Uplink 435.725 MHz FM w/subaudible tone 151.4 Hz
Downlink 437.925 MHz FM
Not operational. No operation in 1999 or 2000 has been observed.
MIR PERSONAL MESSAGE SYSTEM (PMS)
Uplink/Downlink 145.985 MHz FM 1200 baud AFSK
Not operational.
HOW TO WORK R0MIR-1
The MIR Space Station is currently orbiting the Earth about every 95
minutes while traveling at roughly 17,000 MPH. Due to the fact that
MIR is a
moving
object, and radio frequencies being involved here,
Doppler corrections may be needed. On the
2 meter band
, the Doppler is
a maximim of 3.5 khz on a pass directly overhead (90 degrees). On a
pass say 10 degrees above the horizion, the Doppler is small about 1
khz. This can be a very important factor in working the packet
Personal Bulletin Board. This is because packets may become distorted.
Here are some items to look at in your station for sucessful attempts.
1.
LOCATION
If you are in a bad location where it might be difficult to get a
signal out, you might be limited to the number of passes that you can
work. You might want to look into a simple 1/4 wave 2 meter
groundplane. This antenna has a good lobe looking up. If you are in
the clear to your horizions, you have it made. However, Doppler and
antenna type will be your disadvantage.
For the average HAM station running say a 50 watt radio, and a J
pole antenna has a great advantage on MIR passes that are up to about
20 degrees above the horizion! Doppler isn't a real consideration and
your antenna pattern is ideal for something up to 20 degrees above the
horizion, or a bit more! Most radios will work, and no frequency
corrections are needed. Doppler up on UHF is around 10 KHZ and Doppler
compensation is needed! A MUST for SAFEX or any UHF satellite
operations.
Note: SAFEX not operational at this writing.
2. TRACKING
You will need some satellite tracking software to know when and
where MIR will be in your area. There is alot of tracking software
available on the internet. I use STSPLUS, and have for over 12 years.
Keplerian information
on MIR and other satellites is updated twice
weekly, and probably can be found on your local BBS.
3. FREQUENCY
The frequency is 145.985 SIMLPEX World Wide. (1200 baud packet and
Voice). This frequency will change in the very near future to a split
operation for voice and packet on different uplink frequencies. Stay
tuned for updates.
4. PACKET WISE
If you are not familar with packet connections or mailboxes, do some
expermentations on the ground first before trying to operate MIR.
The TNC on MIR is a Kantronics KPC-9612+ V 8.1 and is operating at
1200 baud ONLY. Here is the HELP that you would get on R0MIR-1 when
using the Help (H) command:
B(ye) PBBS WILL DISCONNECT
E(dit) n [BPTYNFH] [>tocall] [ call LIST MESSAGES FROM OR TO CALL
LB LIST BULLETINS
LC [cat] LIST CATEGORIES
LL n LIST LAST n MESSAGES
LM(ine) LIST UNREAD MESSAGES ADDRESSED TO YOU
LO [+.|-] LISTING ORDER
LT LIST TRAFFIC
LTn DISPLAY LOCATION TEXT n=1-4
K(ill) n DELETE MESSAGE NUMBER n
KM(ine) DELETE ALL READ MESSAGES ADDRESSED TO YOU
R(ead) n DISPLAY MESSAGE NUMBER n
RH n DISPLAY MESSAGE n WITH HEADERS
RM(ine) READ ALL MESSAGES ADDRESSED TO YOU
S(end) call SEND MESSAGE TO callsign
S[B.|P.|T] call SEND BULLETIN, PRIVATE, or TRAFFIC
Please don't use the Help command on MIR! This is STANDARD to MOST
TNC's and doing so just limits the use of MIR by other stations.
There can only be ONE user connected to R0MIR-1 at a time.
5. BE PREPARED
If you wish to send a message to the crew, have a file of message
READY to go! What I usually do is make a message to R0MIR BEFORE I
even send it. On my KPC-9612, I get in my mailbox, and SP R0MIR@MIR.
Then enter the subject and then the message. When MIR is in range, and
the mailbox is not being used, I forward the message. My TNC talks to
MIR's TNC and goes through the forwarding process. This is A LOT
quicker! I send 3.7K of info in one minute! This includes the connect
to disconnect time. Consult YOUR TNC users manual for forwarding mail
to a station.
Don't try to send a message to your buddy down the street to MIR's
PERSONAL Mailbox. It will NOT allow 3rd party messages. If you try,
you will get a response - MESSAGES MUST BE ADDRESSED TO THIS STATION.
6. BE COURTOUS
Please don't try connecting to R0MIR-1 when someone else is already
connected. You will get a R0MIR-1 **BUSY. When you get this, don't
keep trying while others are connected. This just messes up the other
station, and it is interference and will just take that much LONGER
for the user to finish before he/she disconnects. Would you like
others interfering with your connects to MIR? Look for the D frame
from R0MIR-1 to the connected station. Using MCOM ON will allow you to
see all these packets. Here is what MY KPC-9612 would show.
R0MIR-1>WA6LIE/1 [05/13/98 22:18:04]: <>:
After you see this, hopefully, the ground station has sent his/her
disconnect to R0MIR-1, and it will be ready for the next connect.
R0MIR
This is the callsign of MIR. This port has no value to working MIR
except credit towards a QSL card. There is nobody at the keyboard.

R0MIR-1 MAILBOX INFO
There have been a lot of requests of information on HOW TO WORK MIR?
I have sent out MANY bulletins on this, and Miles Mann WF1F has done
the same. We don't know if it is because it isn't posted enough, or if
all the MIR users just climbed out from under a rock. We have NO IDEA!
DO's
---------------
- DO be courteous of "other" HAMS on frequency wanting to work MIR.
- DO be patient, as others will wait for "you" to finish your connection.
- DO WAIT for others to "finish" with their connection to MIR.
- DO youself a favor. BE PREPARED!
- DO use MIR's "PERSONAL" mailbox to send "informational NEWS" to the crew.
- DO one to "others" as you would expect to done to "you".
- DO "listen" to packet or VOICE on MIR's frequency. (with a speaker)
- DO "wait" for a D frame to the connected user. eg. R0MIR-1>WA6LIE <'D'>
- DO use the MCOM ON paramater in your TNC to see <'D'> frames etc!
- DO your operations (if possible) when users in your area are alseep.
- DO be "familar" with "your" packet station and ALL of it's operations!
- DO use satellite tracking software to know when and where MIR is!
- DO use a pre-amp and a satellite type antenna if possible.
- DO send this information to ALL interested in the R0MIR-1 PERSONAL mailbox.
- DO "REQUEST" additional information if this isn't enough!!
DO NOT's
---------------
- DON'T Connect to R0MIR-1 "just to do it".
- DON'T use MIR as a digipeater to connect to another station(s).
- DON'T "beacon" on MIR's frequency. (having MIR in your digi unproto path)
- DON'T continue to send packets on frequency when the crew is on VOICE!
- DON'T make "blind" calls to the crew on VOICE.
- DON'T send "personal" messages to your friends on MIR "just to do it".
If you attempt so, you will get a message like this:
MESSAGES MUST BE ADDRESSED TO THIS STATION
Note: All 3rd party messages are NOT ALLOWED! This because the crew
is NOT familar with TNC/PACKET operations, and can NOT maintain the
mailbox.
This requires a lot of TIME! Who ever does it! The "old" pacomm TNC
had less than 32k memory, and it would fill up in 1 day! Therefore,
the MIREX SYSOP has to do this. On 2 meters, and on "your" time to
maintain the mailbox. This was a TOTAL MESS and was ABUSED!
It is typical for the SYSOP to take 2 passes just to maintain the
mailbox! This means there are 2 passes LESS that users might get to
use! Anyway you look at it, only ONE USER AT A TIME can be connected
to R0MIR-1.
- DON'T ** SEND MAIL TO THE CREW FOR QSL REQUESTS!! ** (see QSL info above)
- DON'T continue to send connect requests to R0MIR-1 when a user is
connected.
- DON'T "expect" to be sucessful if you aren't PREPARED.
- DON'T "expect" return Mail from the crew! (out of XX msgs sent, 0
returns)
- DON'T Send Bulletins to R0MIR! eg. SB R0MIR Please don't do this!
- DON'T be afraid to "ask" myself or any other MIREX board member for
info!

SUMMARY
The MIR Space Station is orbiting the Earth at about 240 miles above
us, and traveling about 17,000 MPH! This covers a lot of ground pretty
fast! An average pass for a "non satellite"- average VHF 50 watt HAM
station will only be able to use 4-5 minutes out of a 10 minute pass!
Therefore, it is important that you are prepared. Those that choose to
keep trying to connect to R0MIR-1 while a (one) user is connected
already, you are just causing "INTERFERENCE" to other radio amateurs,
and ethically is wrong.
So, please be aware of what you are doing, and it will make it
easier on ALL others that cooperate and show some respect for their
fellow amateur. If you are NOT decoding packets from MIR, don't try to
make a connection! ONLY ONE (1) USER AT A TIME CAN BE CONNECTED TO
R0MIR-1.
R0MIR-1 is "intended" for use by the "crew". It is a PERSONAL
Mailbox. It is "just like" your own mailbox on your TNC at home! A
PERSONAL mailbox!
Think about it......

We are sorry if this offends anyone, but it apears that one must be
BLUNT and to the POINT! I hope you can understand, so you can teach
others! That is what HAM radio is about! Learning/Teaching correct
Amateur techniques!
