Ted,
I worked the last pass over SoCal from my driveway with 500mW. I had little
trouble getting in once it cleared the local obstructions.
Hand guided Elk with VFO Doppler tuning. I think most people have outdated
keps so they're way off. I've worked this bird a couple times now and never
over 2.5W with 817 as an uplink. As usual, QRO isn't the answer.

Hi Mike,
Good to work you on the last 06:00z pass. Also heard KK6OTJ, but never
made 2x contact.
For a change, the bird seemed alive and well from the beginning of the
pass until nearly the end (vs before when I couldn't work it until after
TCA). In fact, it seems like it was too active too soon, suggesting my
keps are late. I'm using the keps from object 41909, updated from
Celestrak right before the pass. Is that the best set?

Message-ID: <000001d265d0$fe423340$fac699c0$@xxxxxxx.xx>
Content-Type: text/plain; charset="us-ascii"
.. I am a bit in trouble :-)
For APRS (ISS, PSAT, ..) I have recently put a Kenwood D710 in my car.
Worked fine. I used the MCP2 program to program memories & settings.
Until I decided today to update the firmware: from 2.01 --> 2.10.
After that I could not use the MCP2 software anymore.
Doesn't read any data from the radio any longer, it sticks at 0%.
Re-did the firmware update, same result, still doesn't read.
Doesn't write either btw. ('model / market code does not match')
Tried to also update the Panel Firmware (maybe this was a combo ?).
Doesn't work either: says cannot find Panel.
..but the panel is connected and works fine !
Cannot find anything on Google reporting the same (apart from G4ILO,
but the poor man is SK).
Any clue anyone - there must be plenty of D710's installed for
satellite operations.
Or else: does someone have a previous version of the firmware, such
that I can try if a downgrade would work ?
Thanks

I was just updating my D710 yesterday, to panel version 2.13. There is a
note in the Kenwood doc for the 2.10 update saying that you?ll need an
updated version of MCP-2A after this firmware update. Try downloading the
latest MCP-2 (it is version 2.3.1, I think).

Greg,
Thanks for the QSO. I was able to hear you down to my visible LOS, San
Gabriel mountains do a good job of blocking the birds to the north.
As far as keps go if you're using the Celestrak New Launches then you have
the most current. Even with that it seems like people are sometimes off
enough to struggle getting in. This seems to be where hand guided has the
upper hand, pun intended. Unfortunately, it seems like this isn't going to
change considering the short expected life.
QRO probably helps a few because they're catching the bird with a less than
optimal part of their antenna radiation pattern. RX quality can lead you to
think you're in the right direction but I think I could receive this bird
with a BNC stuck in a potato. I actually heard WD9EWK the other day near LOS
with Elk laying on top of my truck.
Personally, my biggest struggle is the delayed audio. I catch myself
speaking slowly and noticed other operators doing the same thing. When I
listen to my recordings I almost sound like I had one too many cold ones
before the pass hi hi.
Scott probably hit the nail on the head as to why activity has been a little
slim. I haven't been on as many passes because we have been getting some
rain for a change.

Dave (W8AAS) and Arno (PE1RDP) gave some valuable suggestions....
which made me check the procedures again.

Subject: [amsat-bb] BY70-1 Observations
Message-ID: <20170104064001.D4FD589A5@xxxxxxxxxx.xxxxx.xxx>
Content-Type: text/plain; charset="us-ascii"; format=flowed
I had a chance to run some tests on BY70-1
this evening from my Arizona Station since there
was no one on the pass. It was only a 15 degree pass
for me but the satellite did very well.
BY70-1 is much stronger than SO-50. The morning passes
are around 500KM and the evening passes are only 250KM.
But the signal is quite strong on both. If you are having
trouble hearing SO-50, try BY70-1. You should hear it much
better.
At first I thought the sensitivity might not be very good, but
upon further testing it was possible to hold the satellite
at 1 watt provided that you were on the right polarity at
the moment. I was changing between horizontal and vertical
frequently. The wrong polarity produced noise, but a switch to
the opposite polarity yielded a full quieting signal consistently.
Many have experienced dropout when attempting to talk through the
satellite. Sometimes it is due to the many signals present on
the input frequency including those that are not coming from
satellite users. It's the same situation on SO-50. But there
are also dropouts that occur when there is no one else on the
input.
It seems that if you are fairly wide in deviation, certain
speech will cause the satellite to stop transmitting. This
may be a receiver bandwidth issue or perhaps the PL
decoder responding to voice frequencies etc. At any rate
I think the dropouts are due to the PL decoder not decoding
the PL tone for the above reasons.
BY70-1 seems to be less sensitive to dropouts if you use narrow
band FM on the transmit. I found very little difference in the
repeated audio level when using wide or narrow. So there is
signal processing in play which keeps the audio output level
constant. AO-85 audio levels do change quite a bit between
wideband and narrow. So do use narrow FM on this bird for
best results.
The signal processing also apparently causes a significant
delay in the repeated audio. It can cause some discomfort
but keep the rx level low so you are able to ignore the delay
and converse normally. Audio quality is quite good.
Some have thought there is some sort of VOX on the bird
but a dead carrier seems to hold the transmitter keyed with
no audio present. Again, the PL Decoder is likely responsible
for the dropouts.
Be sure to download the latest keps from Celestrak or apace-track.
The keps on the amsat site may not always be current. The orbit is
changing daily so get the new keps every 24 hours. The catalog
number is 41909. http://celestrak.com/NORAD/elements/tle-new.txt
The amsat nasa.all file can be edited with Wordpad and the new
keps can replace the ones in the file if different. Set your PL
to 67Hz just like SO-50.
doppler.sqf:
BY70-1,436200,145920,FM,FM,NOR,0,0,FM Voice
BY70-1,436200,145920,FM,FMN,NOR,0,0,Narrow FM Voice
The coordinated frequencies seen to be close enough.
I have asked KX9X to facilitate adding BY70-1 to the list of
satellites in LOTW.
Don't be reluctant to try this satellite. You will find
it much easier to access than SO-50 or AO-85. It does have
a short window but you can hear it down low if you don't
have any obstructions.
73,
John K8YSE/7

ARISS thanks everyone in advance for their assistance. Feel free to send
your reports to aj9n@xxxxx.xxx or aj9n@xxx.xxx.
Listen for the ISS on the downlink of 145.8? MHz.

Several of you have sent me emails asking about the RAC ARISS website and
not being able to get in. That has now been changed to
http://www.ariss.org/
Note that there are links to other ARISS websites from this site.

If you need some assistance, ARISS mentor Kerry N6IZW, might be able to
provide some insight. Contact Kerry at kbanke@xxxxxxxxx.xxx

Good observations, John.
It's a tricky satellite at times, but still fun to play around with.
It's certainly a shame that it'll have such a short lifetime due to
the partial launch failure.
I have also sent an email requesting it's addition to LoTW.
Just a general FYI about new satellites and LoTW: The name of the
satellite is not able to be changed once it is added to the TQSL
configuration file. After a satellite is made available to the amateur
community, I have advised the ARRL to hold off on adding satellites to
the configuration file until an OSCAR number is issued or we are
certain that no OSCAR number will be requested and/or granted. I did
ask about BY70-1 with no response, so I consider that such a request
is unlikely at this point.

Paul, N8HM

Hi All,
For BY70-1, an open telecommand is designed to allow radio amateurs to send
commands to take and download an image. The following article provides some
