Even without the yagi, I bet you could of gotten in. I've worked APRS on the
D7

I'm wondering if anyone can recommend a USB to serial convereter that works
well with SAT32PC and an ICOM 706 or a FT 736.
Conversely if anyone has had bad experiences that would be usefull to hear
about as well.?? I've heard that some USB to serial converters work better
than others.
Many thanks

I've always had excellent results using Keyspan adapters. I've had some good
results with "No Name" adpaters, but it's hit-or-miss, depending on what
chipset they use for the USB-to-serial converter.

Hi Gregg,
Yes, I have worked the ISS APRS from the D7, but I thought the 145.800 voice
downlink was paired with a 1.2 ghz uplink this week. I didn't think to try
the other modes. Are they up too?

I just bought a new laptop with no serial ports and Vista installed. I
bought 2 Sewell SW-1301 USB/SERIAL adapters to use with it for digital modes
and Satpc32 control. They sent drivers at level 3.0 that worked fine with XP
but would not work with Vista, however I did locate newer drivers for the
chipset, level 3.2, that work perfect with Vista. The adapter is
inexpensive, $12.45 US. I am connecting to a Kenwood TS2K. Performance seems
to be very good, better than the native serial port on my old, now dead,
Gateway.
Sewell Direct can be found at http://sewelldirect.com/
I'm sure there are others just as good, and maybe better, but these are
plenty cheap and they do work.
Good luck and 73 ...

Thanks to the control station turning AO-16 back on. Heard the sequence
and then the bird was really kicking butt on its signal. I lowered my
power to 5 watts and was still banging in and this with some very "bad"
verticals that I have difficulty with on the other birds. Heard to
satellite quit during the pass and then obviously, control station came
back and turned it on again. Other then some "junk" only a couple of
stations were on.
I had a choice of AO-16 or SO-50. No brainer, stuck with AO-16.

Mark,
Keyspans are good. I have only one, really old, obscure piece of software
which won't work with them.
I got a rig programmer from RT Systems, and picked up one of the RTS-03 as
they guaranteed it would work. It did, and with everything else I tried it.
Somewhat brand X, but it uses the FTDI chip set.
http://www.rtsystemsinc.com/othercables_template.cfm?cfid=3106444&cftoken=39

Something to consider is an adapter by Parallax. Go to WWW.PARALLAX.COM and
put in the part number 28030. It uses the FTDI chip set, and is designed to
be used as a programming controller rather than just a communications
interface, so it brings out a few more lines than does the typical USB to
serial converter. Some rigs may need those. With the USB A to mini USB B
cable it is about $20. I have never found a rig or similar control function
it will not support, even when making house calls. The only drawback it
that it doesn't really have a case. With a little Exacto knife work you can
modify a cheap plastic RS shell to fit.

My pleasure Reid. Up until today I had been optimistic about maybe eeking
some sort of continuing operation out of AO-16, but this pass has sort of
killed that. We had been getting an orbit or two between shutdowns the last
week or so, which led me to think if we could enable it every orbit we'd
extend operations. Right now the satellite is in about 79% sun, by this
summer that will drop to 68%. Illumination equals heat, and our reset
problem is temperature dependent. The temperatures have already dropped
enough that the satellite reset twice during that pass; the time you heard,
and about 30 seconds after I first turned it on it did the same.
So...we'll have to see if even a large effort will result in any sort of
usable operations as we approach that 68% number.

Hi Drew,
I'm sure you and the command team have already looked into this, but are there
any "knobs" to turn that could indirectly warm up the satellite a bit? What
comes to mind is to reduce the Transmit power. I think you used the reverse
process to cool off AO-51 earlier this year (higher power draw cools off solar
cells).
Just a thought,

Will do Drew. Especially if I hear him on AO-16. I knew it had a good
receive, but wow, the transmit was good so that I could hear it on my
crummy verticals. I really do need to get the arrays back up that have
been down since the storms of '04' and I'm finding that a couple of
birds it would be very beneficial (especially for AO-7). Again, I took
my power into a homebrew 1/4 ground plane down to 5 watts and was still
hearing quite a signal. My goal is to try and use this bird as much as I
can until it goes away.
Again Drew, thanks for your and other's efforts on this. It really makes
operating the birds fun. Especially when those of us are too lazy to put
the better antenna up or back up, hi.

Indeed we have discussed it, and will try it. To be honest, it didn't make as
much difference temperature-wise as I thought it would on AO-51, but it's
worth a shot.

The FTDI chip set seems to be the best way to go. I bought my adapters
through Parallax, for $14.95 plus s/h. I have found nothing that doesn't

Hi all.

I have some by Murata. Types BLFYM-455C and BLFCM-455C but these are +/-
12.5k.
Any ideas? I've checked Digikey, but they only seem to list narrow band FM
or AM filters.
Is there a Murata or Toko distributor that I've missed?
Thanks

I am new to working the Sats so if I am in need of "directions" please feel
free to set me in the right direction.
With that said, I am having problems working AO-07 and the other SSB sats.
I can copy stations vary well but I can't seem to keep on track with them.
I am using HRD and a TS-2000. The antennas are a KLM on the 2m side without
the phase switch hooked up(got cold on me too soon) On the 432 side I am using
a home brew Yaga that I found on KC4UMO's web page. It seems to be working OK.
I really think it me and the tuning. Can anyone point me in the right
direction on these birds?
On the 2230 pass for AO-07 I called K3SZH and I think he was calling me back
but I couldn't keep up with the tuning.
Later when I found him again, he was in a QSO with another station and I
thought I better not interrupt.
Sorry Joe. I did hear you talking about me. Any information would be a great
help.
Marv.
