I'm not sure how worried people are over 420 - 430 since there's parts of
the US you can't operate in those 10 megs. Down there from what I
understand, though I could be wrong, is amateur TV. The important thing is
we don't lose the 430 - 440 segment because that's where a lot of activity,
satellite links included, happens on 70cm. Taking away 450 - 470mhz would
also essentially kill both the FRS and GMRS bands as well which, while not
always hams, is regularly used by thousands of people.

True, and in Europe, where thay only have a 10MHz wide band, ATV has
gone to 23cM using FN, not AM. Makes old satellite TV receivers usable
for the Rx side without modification other than a preamp.
I guess it would be a struggle getting all the US FM repeaters into
433-435 and 438-440 but most in this area are unused anyway.

Hello:
I had a few questions about the operation of the Yaesu 736r.
1: I am on one of the SSB satellites (440/2 meters) - I hear my signal
coming back down and all seems fine. Shortly afterward the RX and TX
frequencies are not in sync so I need to adjust one of them to find and hear
myself again. Which is best to adjust RX or TX?
2: In trying to make life easier by using the Memories Recall (MR) on the
unit. I put in the frequencies of the centerband of each of the satellites.
It is easiest to quickly adjust my frequency by just selecting Memory Recall
1, 2, 3, etc. That works fine for the FM satellites, but I am locked into
that frequency on the SSB birds and I cannot use the VFO to adjust +/- my
frequencies. If I hit VFO I go back to the frequency I was using before I
did the Memory Recall. Is there a way to use the Sat Memories yet have the
VFO work when you get there without changing the Memory contents as you
would if you used the VFO/M button? Any tricks?
Thanks for your time.

Bill, all of my matches, besides the 3 blanks, are coming back VUCC SAT.?
Maybe
someone else can answer the why yours are coming back VUCC144 or 432?? Not
sure
where the imput error is, if there is one! Maybe the Propagation is being
recorded as 144 or 432 enstead of "SAT" Sorry can't be of more help...

Yes, Go into SAT mode REV. Then press MR if not already in that mode and
dial the channel number of the frequency pair you wish to use. Then press Fc
then VFO. That will load your memory channels into the VFO's and also switch
you to VFO mode.

Hello:
I had a few questions about the operation of the Yaesu 736r.
1: I am on one of the SSB satellites (440/2 meters) - I hear my signal
coming back down and all seems fine. Shortly afterward the RX and TX
frequencies are not in sync so I need to adjust one of them to find and hear
myself again. Which is best to adjust RX or TX?
Ansver:
There is rule of thumb but I think it is not good idea. Try this - During
transmitting - set SAT swith to TX pos. and try tune VFO to hear your
downlink signal readable (continuos tuning), during receiving set SAT swith
to RX pos. and follow correspondent frequency and when you will transmit
again to correspondent set SAT swith to TX pos. and quickly tune VFO to find
your signal. I made a lot of QSOs that way using FT736R and set of two
diffrent radios (2m/70cm).
FT736R has no special knob to Doppler correction (like TS 2000 has) and
without CAT Doppler correction you will have to use SAT swith many times ...
2: In trying to make life easier by using the Memories Recall (MR) on the
unit. I put in the frequencies of the centerband of each of the satellites.
It is easiest to quickly adjust my frequency by just selecting Memory Recall
1, 2, 3, etc. That works fine for the FM satellites, but I am locked into
that frequency on the SSB birds and I cannot use the VFO to adjust +/- my
frequencies. If I hit VFO I go back to the frequency I was using before I
did the Memory Recall. Is there a way to use the Sat Memories yet have the
VFO work when you get there without changing the Memory contents as you
would if you used the VFO/M button? Any tricks?
Ansver:
YES - in memory mode push FUNC button and then VFO button, it will transfer
memory SAT frequences to VFO (SAT VFO) without affect content of memory that
can be recalled by pressing MR button. It also works in regular simplex
memories.

At times like this, the military are usually great bedfellows on the
bands, because their interest is in keeping the band clear for their
own use, and they have much more money and clout than we hams do.

Australia has nominally 420-450 MHz, but 420 - 430 is unavailable in
all of the major populated areas, so the band is effectively only
430-450 MHz for most of us these days.

That's where our repeaters sit here, with 440-450 being ATV and
site-site links.

As with all HEO theories, we have to take this as one with a burden of
expenses. My idea of a baseline is also an AO-10 or 13 type bird.
Propulsion and getting a ride To the HEO orbit is very expensive. AMSAT,
without having help from other interested parties, cannot possibly meet
expenses on this. With a ride offer from one of the launch facilities,
Satellite enthusiasts could possibly raise enough money to get this to
happen. ITAR is not helping this AMSAT group bonding to give this a chance.
Please let your wishes in this direction be known to any AMSAT people. I
have been accused of having my own agenda for HEO birds. Remember, we
cannot possibly afford this (unless a rich uncle leaves us a sizable amount)
and this is why our officers want to stress the present usable LEO birds as
our foreseeable future. Have faith and maybe the status of launches will
change and all this will be a mute point.

Linear birds are a good idea, and the idea of creating an "off the shelf"
transponder package that university groups can install into their projects
has been discussed here before, to help that end. larger footprints would
be nice (and extremely useful in this part of the world), but the trick
there is getting the launch opportunities at an affordable price, since it
seems most affordable launch opportunities are to LEO. You can only place
your bird where the ride takes you, unless you add propulsion, which means
extra weight and complexity (meaning more cost, fewer launch opportunities
and higher risk of failure, and most likely fewer birds).
One of these days, I'll have a crack at the linear birds we have. I have
the gear, just have to get around to using it! :)

These guys are great! I had the privilege of riding to the AMSAT symposium
this year with Bob Twiggs and part of their team. Earlier last year when
NASA flewtheir SOCEM mission (suborbital cubesat), it was a great ride. This
one should be even better.
Keep you ears open for this bird. Unless something fails, it should do
good.Also check out their Twitter and YouTube page for info about the

Looks pretty real to me unlike the ARRISat which I think they should just
zip tie to the outside of the spacestation somewhere!!! At least then it
would last and they could play with it if need be. Anyway just thinking out
loud.

I am awaiting delivery of a Gulf Alpha dual band antenna that I plan to
mount on a single mast for azimuth-only control.? I've read various reports
of metal masts causing polarity (?) issues and others that say they are ok
as long as you don't align the elements with the mast etc...?
So - what is the real scoop.? Should I be concerned with mast material with
the above setup or is a traditional metal mast fine?? If not, any
recommendations would be greatly appreciated.? The stronger the better IMO.?
Although I realize there is a pretty minimal wind loan, and it will be
mounted in a Glen Martin 4' roof tower, I'd rather not worry about my mast
snapping in the wind...
Thanks,

Bill,
It might be worth taking a look at SATPC32. It supports the rig and handles
the Doppler issue automatically. Because of limitations in the CAT control
you need to tune with the program rather than the knob, but that is easy to
get used to.

I'll be QRV on VO52 this evening at 22/0603Z. This will be a low pass
for me at 8 degrees max, so it'll be mainly for testing my station's
receiving capability. It's apparent that my problem with hearing my own
downlink at low elevations on the linear sats will persist, at least
until I can change out my antenna when we arrive in California next
week. (I'll be putting an Elk on line in place of the Arrow that I've
been using.)
I should be able to rearrange my lunch schedule to take advantage of the
first window opportunity on AO27 tomorrow afternoon when it turns on at
about 22/2333Z. Later at 23/0155Z, a small window will open up on AO51,
followed by AO7 with a footprint extending to the central states at
23/0249Z and another one the next morning at 23/1645Z.

One additional trick: Once you find yourself (and congrats, if you can do
that, you've got the hard part done!), stay in (or change to) REV mode and
spin the dial around to find a CQ to answer, or a QSO to join. In REV mode,
the Rx and Tx VFOs will track each other in the right directions (for our
current crop of "Inverting" transponders), so that you will be pretty close
to having both sides in sync when you want to step in; otherwise, you'll
have to find yourself all over again. Then drop back to Rx (which is
usually the higher of the two bands) so that you can track the other
station. If you haven't found a place to land for a few minutes, drop back
to Rx and find yourself again, then back to REV to continue the hunt.
You'll need to do this because Doppler will affect the higher band more than
the lower, and you'll be off frequency.
Good luck!

Hi, Zach
Is this one of his single antenna models? I have his "Easy Satellite"
antenna, and used it to make 35 contacts on Field Day.
If it's a single antenna, like mine, you can rotate the boom in the
clamp so the elements are in an "X" position relative to the mast. This
puts each set of elements at 45* to the mast, very similar to the
suggested mounting when using two antennas on a metallic cross-boom.
That's how I mounted mine, and it works beautifully.

Although I realize there is a pretty minimal wind loan, and it will be
mounted in a Glen Martin 4' roof tower, I'd rather not worry about my mast
snapping in the wind...
