After recently acquiring an ICOM IC-9100 Transceiver to upgrade my
station, my previous satellite radios are for sale.

ICOM IC-475H All mode UHF transceiver.  75 watts out.
DC power cord, hand microphone and manual included.

ICOM IC-275A All mode VHF transceiver.  25 Watts out.  Some panel lights
burnt out.  Does not affect operation of radio.  I have a couple of
spare bulbs which will be included if you want to open the radio and
replace them.
AC power cord, hand microphone and manual included/

I have used the radios on the satellites since the AO-13 days and was
using them on the LEO birds until earlier this month when when I
purchased the IC-9100.

The radios are in very good shape.  I can provide pictures and answer
questions off line.

I am asking $600 for each radio which includes shipping and insurance to
the lower 48 states.

Please contact me at k6fw1 at verizon.net.

Thank you for reading this listing.

I have my compressed APRS packet from the Duchifat folks, but I can't
figure out how to get MixW to send it correctly. It sends the compressed
packet, then sends the directions, then sends a Carriage Return, then
sends the packet again.

I think I want the directions "AI9IN>4X4HSL" first and then the
compressed packet, don't I? Can anyone help me get this set up. The
Duchifat pass is in about 40 minutes.

I forgot (or didn't know) about the downlink being BPSK/USB. At the
moment I don't know how to do an uplink in one mode and the downlink in
another.

I have an eggbeater, so tracking is not an issue. (I acknowledge that a
rotor and a yagi would be better, but I'm working with what I got).

Anyway, on this pass I heard nothing, but I was listening in FM. I have
heard the CW ID a few times in the past. Guess I was listening on USB
those times.

An FM APRS signal has been received in England causing interference to the
MGM frequency and weak-signal Meteor Scatter operation which is just below
144.390 MHz.

A MS DXpedition was disrupted by such activity earlier in the month and
interference has been occurring at various times since. The APRS frequency
in Europe and Africa is 144.800 MHz.
Today (July 30) a signal on 144.390 MHz has been decoded as

15:17:27$ fm W3ADO-1 to BEACON-0 via SGATE-0 UI PID=F0
T#004,161,161,042,210,215,11111111,0011,1
Now I know nothing about Sat Gates and how they operate but I presume that
is what the SGATE-0 is referring to ?

I have seen a reference to W3ADO-1 at
http://www.db0anf.de/app/aprs/stations/basic-W3ADO-1
Does anyone know if 144.390 APRS is installed on any current orbiting
satellite or is anyone aware of a terrestrial network that may be relaying
APRS traffic on 144.390 in the British Isles or Europe ?

So sorry, but yes.  "Houston, we have a small problem..."  I hate to say
it, but that beacon was IARU coordinated 15 years ago for operation only
when PCSAT is over North America, but after 14 years on orbit, we have
lost the ability to turn that backup beacon off.

PCSAT (now 14 years old) had a backup fail-safe beacon on 144.39 that
would activate after any unknown spacecraft reset to give us a backup comm
link in case the primary 145.825 channel died.  Being on the North
American APRS frequency with hundreds of IGates there would always be at
least one that would hear this "emergency call home" from PCSAT even
though the channel is generally saturated.  And it worked.

The problem is, that now PCSAT resets on every orbit due to negative power
budget and so, on every orbit that beacon comes back on.  Even if we did
get a command up to reset it, that setting would last only 15 minutes to
the next eclipse.

We learned our lesson!  That was our FIRST amateur satellite and we sure
learned NOT to use a "connected-packet-command link" that needs ACKS and
Retries and logon passwords  just to LOGON before you can even send a
SHUTUP command.  All our satellites since, operate without the multiple
Send, connect, ACK, retry, ACK, command, ACK overhead.... just to get one
command understood.  Now, only the receiver on the spacecraft has to be
functional to command it to silence in a single packet.  But too late for
PCSAT.

We are sorry that we have no good answers.  But we hope we can mitigate
this instance of "friendly fire" collateral damage so that we don't cause
an overall black-eye to amateur radio overall friendly operations?

What you may hear will be 2 one-second packets per minute, one at 1200
baud and one at 9600 baud, trying to "call home".

W3ADO-1 on 144.390 is most likely PCSAT NO-44, it has a safemode
downlink on 144.390

All satgates responding to sgate that are used gate from 145.825 to
144.800 in europe but there are not that many, most satgates do not look
at sgate alias and gate to internet everything from 145.825.

Thanks, I'd just found that as well.

I hope that control and deactivation of this transmission may soon be
achieved.

It does though highlight the dangers of installing on satellites
transmitters that operate outside of Internationally agreed bandplans.

Thank you for explanation Bob.
The MS community in Europe has been suffering this interference for several
weeks. I have not seen any notifications on this list that there was a
problem with NO-44.

When did you first become aware of the problem ?

May I suggest that the lesson to be learned is NOT to use frequencies like
144.390 MHz which have not been agreed Internationally for satellite use
across all three IARU Regions.

We need to be careful not to blame PCSAT (which identifies itself in each
of its occasional 1 second packets) for every unknown signal heard on
144.39 in the UK.  Maybe someone could record the unknown interference
being heard so we can be sure to separate the known few PCSAT packets from
all the other possible sources of weak emissions that could possibly be
heard by sensitive receivers?



Then we will know what is and what is not emitted from PCSAT.

though the channel is generally saturated.  And it worked.

The problem is, that now PCSAT resets on every orbit due to negative power
budget and so, on every orbit that beacon comes back on.  Even if we did
get a command up to reset it, that setting would last only 15 minutes to
the next eclipse.

We learned our lesson!  That was our FIRST amateur satellite and we sure
learned NOT to use a "connected-packet-command link" that needs ACKS and
Retries and logon passwords  just to LOGON before you can even send a
SHUTUP command.  All our satellites since, operate without the multiple
Send, connect, ACK, retry, ACK, command, ACK overhead.... just to get one
command understood.  Now, only the receiver on the spacecraft has to be
functional to command it to silence in a single packet.  But too late for
PCSAT.

We are sorry that we have no good answers.  But we hope we can mitigate
this instance of "friendly fire" collateral damage so that we don't cause
an overall black-eye to amateur radio overall friendly operations?

What you may hear will be 2 one-second packets per minute, one at 1200
baud and one at 9600 baud, trying to "call home".

Just got off AO-7 and it's a bit temperamental. Ran min power and lot of
freq shift and qsb. Did Work W5BK ssb, AA5PK ssb and K9CIS cw (of course).
Will not complain too loudly it's the highest bird we have (right now).

Hello Steve,
Sorry for the late answer, I hope it will be useful for you in future
passes! :)
When preparing compressed APRS packet in MIXW for Duchifat1, it doesn't
matter what you use in the From and To fields ('Source call' and 'Dest
call' of the MIXW AX.25 settings).  Duchifat1 doesn't check them.
However, we leave the MIXW  'Digis' field empty.   I am not 100% sure what
would happen if a Digipeating path is added.  At this stage I would
recommend to leave this field blank. (it appears in 'Mode' ('Packet'
checked) > 'Mode settings' > 'AX.25 settings' window> 'Beacon/Unproto' tab)

73 and good luck!
