I got a surprise gift of a Kenwood TH-F6A and look forward to giving it a
try on the satellites. I know there are a few owners on the list -- Drew,
Patrick, others -- and wonder if folks have any tips to share (I've read
through the eham reviews). I'm especially interested in experiences with
speaker/mics and headsets, headphones with 2.5mm plugs, quality of
after-market programming cables, etc. I'll typically be using the F6A as one
of two radios -- the receiver for the easy sats -- and want to record passes
while listening or operating. Thanks in advance for any ideas that will make
its use more effective and enjoyable.

Hello Giulio and BB,
NASA calculates 3 - 6 months lifetime. It has to do with the original
altitude of the ISS, the force and the angle.

The spacecraft is expected to be operational for a period of between 3 and 6
months once in orbit. Please note that this is only an estimate.

Why reward Ted's harsh sarcasm with what he wants?!?! Let him get Kevin's
grid from someone else who prefers sarcasm broadcast to everyone in the

That was really poorly handled. I have yet to make my first satellite

Hi Kevin et al
I hear this alot.? Yes it will require an investment, however it doesn't
have to be excessive.? Ebay and flea markets are full of reasonable? older
Icoms, Kenwoods etc that are fully capable of providing good ssb/cw
operation on our linear satellites.? Granted they may not be computer
controllable, you will actually have to use that big knob.? I suppose this
is the point where one actually gets "serious" about amateur satellites and
the whole process of engineering, funding, promoting, and yes? the politics
of the aforementioned.? We must remember this is rocket science and that
ain't cheap.? Once you have the necessary equipment you will start thinking
of, dare I say a HEO.

Hi Scott,
I haven't used my F6 much for satellites (my D7 is better, but mostly I use
my FT-736r. Warm, in side the shack.
The F6 is an interesting beast. I have used it with an after-market speaker
mike, the kind that clips over your ear and has a short boom for mike
pickup. It works ok, I suppose. The audio volume (from the mike pickup)
wasn't all that good. It's kind of short, and as I don't like talking
loudly into thin air, I kind of cup my hand over the boom and mouth, which
kind of defeats the whole purpose of it. Also the VOX didn't work, and I
think one of the PTT buttons (the one on the speaker mike cord, or maybe the
one on the rig itself, would key up the rig but no audio would come through.
I just use the other one. The volume in the ear piece itself is fine.
You're going to ask me what the make/model is, and I really don't recall.
It was from one of those vendors you see at swap mets year after year.
Nothing is written on the unit itself.
"Fortunately", one of the wires got run over by something and it's in need
of repair. Instead of doing that, I picked up a Pryme SPM-301B at a recent
club white elephant sale. Seems to work in a quick "smoke test", but I
don't have any on-air results yet. The ear bud doesn't clip over the ear
like the other one does, so I'm concerned it might keep falling out, but the
price was right.
The F6 itself, at least mine, is somewhat deaf on the "B" side. If you're
on an FM bird, use "A" for receive, and if you want to transmit, do that on
"B". For SSB/CW, you will have to use the B side, of course. Note that it
is a half-duplex rig, so you will not be able to hear yourself without a
second radio. Also, the B side is pretty wide banded and weakly filtered,
so you're going to get some imaging effects and "intermod" in high RF areas.
If you haven't yet, do invest in some sort of protective cover for the keys.
The lettering on mine is almost totally gone, just from sitting in the side
pocket of my backpack/laptop case.
If you find, one day, that the rig doesn't power up, take the battery off
and give the two spring power clips a little tug. Mine seem to not make
good contact sometimes.
That's all I can think of, off the top of my head. Definitely a cute little
rig, with lots of uses. The B side's wide range and SSB/CW capability makes
it a portable instrument, an IF receiver (for on-roof tuneup of my AO-40
downlink), and the AM/FM radio comes in handy from time to time. Once I
even checked into the regional SSB Net on 2 meters, receiving SSB on "B",
and using the PTT on A for crude CW. (Hey, it worked!) Pity we can't
listen to TV-audio anymore. The Li-Ion battery has very little
self-discharge, so it's always ready to go.
Enjoy,
Greg KO6TH

$800K for 3U Cubesat
Spaceflight Services Announces Lunar and GTO Mission Pricing
Prague, CZ - September 30, 2010: ?Spaceflight Services (Spaceflight) announced
today pricing for small payloads to Geosynchronous Transfer Orbit (GTO) and
Low Lunar Orbit (LLO). ?
Spaceflight, as part of the Rocket City Space Pioneer Google Lunar X-Prize
Team, is responsible for mission integration and providing space
transportation services to Low Lunar Orbit. ?Spaceflight is providing flight
opportunities for ESPA class spacecraft (spacecraft weighing less than 180 kg)
interested in launch services to GTO and Low Lunar Orbit. ?
The proposed mission, which is slated for Q4 2013 or Q1 2014, will deploy
three ESPA payloads into a Geosynchronous Transfer Orbit and two additional
payloads in a Low Lunar Orbit. ?The mission is also open to smaller spacecraft
looking for a low cost ride to either of these destinations.
Mission pricing for small payloads to GTO begins at $795,000 for a 3U CubeSat
and up to $13,950,000 for a full ESPA spacecraft.
------------------------------------------------------------
This is considered a "Low Cost Ride" in the commercial world. This is the free
market value of the launch that we are hoping to get for significantly less.
Wish us luck...

When the Wouxuns came out and had no accessories I used to tell people
to just pick up Kenwood ones. Now that Wouxun ones are cheap on eBay,
I'd say get those - the programming leads are identical and the only
difference between headsets/RSMs etc is that the "real" Kenwood amateur
ones have an extra ring for the remote control pin - which I never use
anyway. Kenwood PMR stuff uses the same kind of plugs with the same
spacing, so if you can program a TK-3160 with your cable you can program
your TH-F7E/F6A.
It's a great rig for the FM sats. Some would say its lack of true
duplex operation is a problem, but I don't. Just set the transmit side
to the frequency and tone you want, then set the receive side 10kHz high
until you find the bird - maybe even 15kHz, check your prediction
software for the Doppler shift. Remember to flip between the A and B
VFO when you tune, and back when you transmit.
You don't have small enough steps to tune the VHF side to match. Make
sure you can hear the downlink before you transmit - you can't hear
yourself, so you've no idea if you'll hear *anything*. If you can hear
the downlink, then if you transmit they'll hear you.
Buy, borrow or make an "Arrow"-type antenna. I used a crossed pair of
WA5VJB "Cheap Yagi" designs on a wooden boom with a homebrew diplexer,
and it worked just great. Bit hard to fold up and put in the car,
though. The one I built was 5 elements on 70cm and 3 on 2m, and
provided more than enough gain to hear AO-51 from horizon to horizon.
This is a great setup for portable operation, or if you don't want all
the hassle of a computer-controlled rotator and CAT cable and all that
push-button-go-chat stuff that people get into. I wonder if they're the
same crowd that only ever use macros on PSK31 - "YOUR RST 599 599 HOW
COPY? MNY THX FER QSO" - you may as well use Skype...

Alex --
Think of these prices as 'retail' costs. Spaceflight Services aims to
provide their customers with a guaranteed ride, and deal with dividing
up the payload space, weight, etc. As such, they will certainly be
more expensive than the 'wholesale' costs you list above.
While this service might not ever be right for Amsat, it does, I
think, show that Amsat's current focus on Cubesat-level
miniaturization through the Fox platform (and AMSAT-UK's work with
FUNcube) is the path forward for both LEO *and* HEO. Here is a GTO
opportunity that is an order of magnitude less costly than others we
have recently been aware of, and at retail costs. Obviously there are
a whole host of challenges that would need to be met, but if GTO is
opening up to 3U and similar configurations, and at a price that we
could even imagine being able to fund, then it's great we're moving
aggressively into that platform.

Hello Scott and all,
I've used my TH-F7E (european version of the TH-F6A) to work satellites in
many ways:
-As a portable HT station for the FM birds using either an AL-800 telecoping
whip or a dual-band beam antenna (Arrow, IOio...). Although full-duplex is
the best way to go, You can work fine using half-duplex. See video for
details:
http://eb4dka.laserenadigital.com/Videos%20AMSAT/VIDEO_EB4DKA%20portable%20via
%20AO27.html
-As the receiver side of my mobile station using a CJU antenna to work FM
and SSB birds (FO-29, HO-68). I use an old Kenwood TM-255 all mode VHF
transceiver and a 1/4 wave mag mount VHF whip for the uplink. This setup
allows me to work full-duplex. See video for details:
http://eb4dka.laserenadigital.com/Videos%20AMSAT/VIDEO_EB4DKA%20via%20FO29%20d
esde%20movil.html
-As IF receiver for my AO-40 base (and mobile!) station:

I found the B receiver as sensitive as A receiver in FM. In SSB I've
compared it with a TS-790 and a PCR-1000 and the sensitivity is almost
equal. The big downside is the bandwith filters in SSB (they're pretty
wide), but you can work quite well if you stay away strong adjacent
stations.
Just my two cents...
