MIR Repeater is back for the moment.

[It was off for awhile until they fixed their packet/voice antenna on Mir, and for the moment, the 2M/70cm split experiment is at least on hold. Here's an explanation from an active AO-27 operator on how to use it, as well. The squelch tail is much longer now, so it's easier to tune by ear with the programming method noted below. -- KD6PAG]

Subject: SAFEX Repeater is UP!!!!


Randy, N7SFI told me that the MIR repeater was up, and sure enough the next
pass of MIR, I made contact with him and VE6ITV.  I was expecting the SAFEX
to be down for a while longer due to the power problems on Mir.  I think this
shows that things are getting back to 'normal'.  

Just for a refresher on the frequencies:

For Repeater mode: Uplink 435.750 with 141.3 PL tone
                   Downlink 437.950

2KHz scheme for FT-736,TS-790,and IC-82x

Program memories with the following splits:

Don't forget the 141.3 Hz tone for transmit.

Downlink   Uplink
437.960    435.740 < Start of the pass (high elevation)
437.958    435.742
437.956    435.744
437.954    435.746

I should be on the 12:42 UTC pass Thursday morning Nov. 6th. (A nice visible
pass in Colorado)

* MIR STATUS * ============== The following is from Michael Foale on-board the space station Mir: Stat : PR Posted : 09/16/97 10:27 To : ALL From : R0MIR @ BBS : BID : Subject: Mir Status Since the EVA with Anatoli and me, we have been getting the station back into a condition to receive the shuttle, and its payload, for which we will have to find space. Priroda has intermittent power, and most likely tomorrow will be turned on permanently. Safex will not be turned on until we are given permission by TSUP in Moscow. Priroda will be sharing the energy from the two Spektr solar arrays, with Krictal, and first priority will be given to complete US and French science experiments that require power in Priroda, starting tomorrow. I have completed the second harvest of Greenhouse, of Brasica Rapa, and will be planting both original earth seeds, and space produced seeds, today, in a new root module. I will harvest all these plants during the docked phase of STS 86, in late September. We have had in the course of a week or so, two GNC control problems with the guidance computer. It consists of 3 identical blocks, which vote. Last week, the computer failed and was switched out in 24 hours with an older unit, still on board. On sunday, the older unit also failed, and yesterday a block from the earlier failed unit was placed into the currently installed computer. Today we again have attitude control, solar pointing, and a margin of power. Mike. R0MIR. [Info via N6CO and WF1F] * UNPROTO PACKET VIA MIR * ========================== The Mir PMS (Personal Mail System) supports a digital repeating mode called UNPROTO. Without getting into too much detail, UNPROTO is a way of sending packet data frames without requiring an acknowledgment from the receiving station. This mode is similar to RTTY in that it is possible to have several stations in one big QSO at the same time. Set the UNPROTO command in your TNC using the command: "U CQ V R0MIR". Switch to converse mode, and everything typed on the packet terminal will be transmitted in UNPROTO mode. If the Mir station hears your transmission, the Mir PMS Digi will rebroadcast your packet within a range of over a 1000 miles. Below is a short UNPROTO contact between a station in Massachusetts and Alabama, using the Mir Digipeater. The stations were arranging to meet on OSCAR 13 when the Mir pass was over. WF1F>CQ,R0MIR*/V [04/21/93 22:22:09]: : hi Tim can you work OSCAR 13? N8DEU>CQ,R0MIR*/V [04/21/93 22:22:30]: <>: Hi miles, yes what freq? WF1F>CQ,R0MIR*/V [04/21/93 22:22:40]: : 145.895 The UNPROTO mode does not guarantee your packet frames will be successfully copied by any other ground station, but if the Mir digipeater does re-transmit your line of text, then you can be assured that someone will see it. The line of text you send will be repeated with an asterisk after it, "R0MIR*". If you do not see the asterisk, then Mir did not hear your packet. UNPROTO does have its drawbacks, but it is much more efficient to use on Mir than the direct two-way connect method. Full two-way packet connects via the Mir PMS are not recommended because they use up too much resources and excessive retires. You can pass 20 times more data using UNPROTO than the full-two-way connect method. Before you try UNPROTO on Mir, it is recommended that you practice using a terrestrial digipeater first before attempting to use the Mir station for Digipeating. (Editor's note: Many terrestrial packet nodes do not pass UNPROTO frames since they frequently add to channel congestion, and do not take good advantage of the node's capabilities.) If you make a few UNPROTO calls and do not get any echo's back from Mir, it is probably because UNPROTO is turned off or because of a collision between packet frames. Everytime the Mir's Paccom HandiPac TNC is reset, UNPROTO defaults to OFF. Also, there is a right time and a wrong time to use the UNPROTO mode with Mir PMS. Do NOT use UNPROTO when: 1. The Mir crew is operating in voice mode. 2. When the Mir PMS is connected to another station that is actively sending/receiving information from the mailbox. The only real safe time to use UNPROTO is when the Mir PMS is in its 5 minute time-out mode when the station connected to the Mir PMS is out of range and cannot log out of Mir. No one can log into PMS mailbox until the connected station times out. Time-outs are the best time to use UNPROTO. Before using UNPROTO, monitor Mir's downlink to see who is using the PMS mailbox port R0MIR-1. If you do not seen any information packets being transmitted from the Mir PMS to any ground station using the R0MIR-1 port for 90 seconds, you can assume the connected station is out of range of the Mir PMS and its UNPROTO time. The shorter the UNPROTO sentence, the greater your success of a PMS repeat. Long sentences may get clobbered by other stations. If you are in the middle of an UNPROTO QSO and you see someone connect to the PMS mailbox R0MIR-1, you should end your UNPROTO QSO, and let the mailbox user have access to the PMS. Good luck and lets be courteous to everyone. Remember, only 1 station can connect to Mir's PMS at a time, and try avoid using UNPROTO when someone is actively using the PMS.

MIR Information

HR AMSAT NEWS SERVICE BULLETIN 280.01 FROM AMSAT HQ
SILVER SPRING, MD October 6, 1996
TO ALL RADIO AMATEURS BT
BID: $ANS-280.01

The following is provided as a synopsis of MIR information presented over
the past few months.

SAFEX Experiment

SAFEX II, the Space Amateur Funk EXperiment, is an Amateur Radio repeater
which has recently been activated aboard the Russian MIR Space Station
Complex. The equipment has been powered on since July 12, 1996. The first
hardware tests involved the station*s digital speech recorder. Pre-recorded
messages from the MIR crew were copied by many groundstations on 437.925
MHz. The messages have even been received with simple 70 cm hand-held
radios. The following message was copied of US astronaut Shannon Lucid, who
recently returned from her stay aboard MIR:

"Thanks for the radio SAFEX. We just turned it on. And best wishes from the
crew of MIR 21. Hope this is of use to you. Many thanks for the
experiment."

Joerg Hahn, DL3LUM, the SAFEX-International Coordinator, reported that the
repeater was operational on July 19. A short contact was achieved by Matt
Bordelon, KC5BTL, operating as W5RRR (the call sign of the NASA Johnson
Space Center ARC) with one of the MIR cosmonauts. The first use of the
repeater to establish a ground-to-ground QSO was performed between DF0VR,
IV3WLQ, and LY3BH. Dave Larsen, N6JLH, performed the first ground-to-ground
QSO in North America with Scott Avery, WA6LIE.

SAFEX II is a project of the German Amateur Radio Club (DARC), and managed
by the Ham Radio Group, DF0VR, at the German Aerospace Research
Establishment (DLR) in Oberpfaffenhofen. The project is supported by DARC,
DLR, NPO Energia (Russia*s equivalent of NASA) and Russian radio amateurs.

The equipment was built by SAFEX Principal Investigator, Thomas Kieselbach,
DL2MDE. Installation on MIR began during the EuroMir 95 mission. That crew
included German astronaut Thomas Reiter, DF4TR (European Space Agency) and
Russians Sergei Avdeev and Yuri Gidzenko. The three arrived at MIR on
September 5, 1995, and remained aboard the space complex for 180 days.
Reiter operated as DP0MIR throughout his stay, but SAFEX equipment problems
and a power supply failure kept the repeater off the air. The SAFEX team
installed new equipment in the Priroda module, which was launched to become
part of the MIR Space Station complex on April 23, 1996. The new equipment
was powered-on by the MIR-21 crew, which included Shannon Lucid, and
cosmonauts Yuri Onufrienko, and Yuri Usachev. The current (MIR-22) crew
includes Valery Korzun (Commander), Aleksandr Kaleri (Flight Engineer), and
John E. Blaha, KC5TZQ (Mission Specialist).

SAFEX II expands the existing 2-meter operations that have taken place from
MIR for the past couple of years. SAFEX II is primarily a FM repeater with
70 cm uplinks and downlinks. The 30 kilogram payload is supported by three
external antennas. The new capabilities address the busy work schedule of
the cosmonauts by permitting Amateur Radio activity from MIR without active
crew operation. SAFEX II also addresses the team*s commitment to future
technologies. There are plans to improve the station by adding a 23 cm to
13 cm transponder capable of broad-bandwidth modes (such as amateur
television).

The repeater operates under the call sign RR0DL. CTCSS tones are required
to communicate through the SAFEX II experiment. After the repeater has been
activated by someone with CTCSS, other stations without CTCSS can also work
through the repeater. It is even possible to use the repeater to contact
the MIR crew if one of them is at the microphone.

In order to involve the largest numbers of amateurs, SAFEX contacts should
be kept as short as possible. Operators should adjust their frequency to
account for the plus/minus 10 KHz Doppler shift. The following are the
SAFEX 70 cm frequencies for the three SAFEX operating Modes.

Mode 1: FM repeater with CTCSS sub-tone 141.3 Hz.
Downlink 437.950 MHz
Uplink 435.750 MHz
CTCSS

Mode 2: 9600 Baud (G3RUH compatible) Packet Operation.
Downlink 437.975 MHz
Uplink 435.775 MHz
No CTCSS

Mode 3: Pre-recorded digital voice beacon, and may be used for contacts
with the MIR crew.
Downlink 437.925
Uplink 435.725
CTCSS

The 2-meter frequencies used for MIR (preferably in split-mode operation)
are 145.800 MHz (uplink), 145.200 MHz (downlink), and 145.550 MHz
(up/downlink). These frequencies were adopted for MIR and Shuttle
activities at the IARU session of the 1995 AMSAT-UK Colloquium.

The SAFEX II team is very interested in reception reports, and any
technical measurements or oscilloscope plots of the repeater*s signals.

Dave Larsen, N6JLH, is the US MIR QSL manager for contacts made with MIR
crew members. QSL cards must include date, time, and mode of contact. Cards
for SWL reports will not be handled by Dave. If a contact is made with the
MIR packet radio personal message system (PMS), then the message number
issued by the PMS should be included on the QSL card.

QSLs must be sent along with a business-sized self-addressed stamped
envelope (the card will not fit in a regular-sized envelope).

MIR and Third-Party Rules

Russian rules have historically permitted unlicensed MIR crew members to
operate using the Russian club call sign R0MIR. Amateurs are reminded that
there are, however, some limitations for hams in the US. The US does not
currently have a third party traffic agreement with Russia. The lack of
this agreement means that Amateur Radio stations in the US may talk to
Russian licensees aboard MIR, but they may not involve unlicensed third
parties in these communications. This agreement does not affect MIR crew
members, but it does affect US Amateur Radio stations.

ARRL gives special thanks to DL3LUM, DL2MDE, DB2OS, DF5DP, N6JLH,

R0MIR-1's Personal Message System

HR AMSAT NEWS SERVICE BULLETIN 280.02 FROM AMSAT HQ
SILVER SPRING, MD October 6, 1996
TO ALL RADIO AMATEURS BT
BID: $ANS-280.02

The following is provided for those interested in MIR's BBS commands.

Timing is important. If one monitors the 145.550 MHz and sees a
disconnect message from R0MIR-1, then it is time to call.  There are many
stations calling, so the fastest, and just on time, gets the contact.

It is noted that many stations seems to be calling all the time even
R0MIR-1 is already contacted to one station. This makes a lot of QRM and
busy-messages and wastes time.

Markku Korhonen, OH8UV, says that the best opportunity to make a contact is
to be QRV on that time when everybody is  sleeping. 
He reports making a 6 minute QSO a few nights ago.  It helped that there
were no other stations QRV at the time as MIR was flying over Russia and
not visible from western Europe.
He logged on and back came the answer:
                Logged on to R0MIR=B4s Personal Message System
                  CMD(B/H/J/K/KM/L/M/R/S/SR/V/?)>

These commands mean:               

B(ye)     B (Enter) disconnects you from PMS.
H(elp)    H (Enter) or ? (Enter) displays this help file
J(log)    J (Enter) displays a list of callsigns heard (optional date/time)
K(ill)    K n (Enter) deletes message number n (only to/from your
callsign).
KM(ine)   KM (Enter) deletes all READ messages addressed to your callsign.
L(ist)    L (Enter) lists the 10 latest messages.
M(ine)    M (Enter) lists the 10 latest messages to/from your callsign.
R(ead)    R n (Enter) reads message number n.
S(end)    S (callsign) (Enter) begins a message addressed to (callsign).
          Subject: ending with (Enter)
          Text: End each line with (Enter). End message by
           typing /ex (Enter) or CTRL-Z (Enter)
           at the beginning of a new line.
SR(eply)  SR n (Enter) Sends a reply to message n prompting only for text.
V(ersion) V (Enter) displays the software version of the PMS system.

F.ex. Command j gives a list like this:
           09/27/96 23:41
EB1HLI          09/27/96 23:33
EA1EFD-8        09/27/96 23:33
F1PAO           09/27/96 23:32
etc

Markku believes that this should be enough for a QSL. he further notes that
if you have a message ready on your disc it's better to send it first and
then get a message number.  You should put it on your QSL.

Markku says that during the week he has been lucky enough to get QSOs with
R0MIR-1 almost every night as well as FM voice contacts with Valery R0MIR
on three nights.

His rig is n FT225RD with a 130 Watt amplifier and a 2 x 14 el. Cue Dee
antenna.  He notes that no elevation control is needed as his location is
so far north that MIR never gets to an elevation of more than 9 degrees.
The grid is KP34VJ.

information.  He can be reached at: oh8uv@paltamo.

[According to this posting, once someone has at least 'kerchunked' MIR with the correct PL, everyone else can then use it, whether or not they have PL enabled. Note that, MIR is no longer operating in simplex on 145.55, and now uses a relatively standard repeater split (145.2 uplink, 145.8 downlink, or as we notate this in the 'States', 145.80- no pl. The 'third party' rules probably mean that your (unlicensed) daughter can probably talk on your radio to an U.S. astronaut if he is at the control point on MIR, but directly not any of the comsmonats. -- KD6PAG]
