Well, crud. A fellow AMSATer wrote (here? or via private email?) that
the unit was significantly better "for us" after the most current
firmware upgrade.

I cannot stress enough how important full duplex is, especially to the
new op. You know if you made it through, you can peak the antenna
orientation for max signal while transmitting, and it leads to less
congestion and logjams on the repeater.
The 470 and it's successor the 530 were both fine satellite HTs. The
Kenwood D7 is as well. The Alinco G7 is not, although I use the radio
quite a bit otherwise.

what are you using as up and down frequencies?
I have no problem with duplex as long as i have it turned on ;o)
It could probably be better and i have no method to measure how good/bad
the duplex is.
Anyhow on 2m/70cm 2m/23cm and 70cm/23cm i have no problem but i have not
tested it via one of the birds.
Reading the service manual you can see that some values can be changed
with firmware and/or via the "service" menu.

Operating question: FT-736r and HO-68/VO-52
Hello:
I have a Yaesu FT-736r and I am wondering the proper way to set a few
switches for the CW/SSB satellites HO-68 and VO-52.
I can set my transmit and receive in the middle of the uplinks and downlinks
for these 2 satellites.
- then-
For these 2 satellites (2m-440) (inverting) how do I set the NOR/REV switch?
and the USB/LSB switches for the 2 frequencies? A general rule for uplink
freq and downlink freq (USB/LSB)??
(Trying to get it right - from the beginning...)
?
Thanks, Bill

GE Bill,
Let's talk about VO-52
First, chose which vfo A or B. It does not matter, but it helps for
operating different birds.
For this example, use vfo A.
Locate the Sat switch close to the left center and turn to TX.
Your TX for the bird will be 435 mhz LSB
Now turn your satellite switch to the RX position.
Your RX will be 145 mhz USB.
To tune or find your freq.: I decide what downlink freq I want use like
145.900. I place the RX in CW, then change to the TX to CW and dit my way
til I hear it on 145.900. Then switch the TX to LSB and my RX to USB. You
should hear your downlink just fine. Watch your power like 5 watts and tune
your TX to your RX freq. It will move as the bird moves across the sky.
Don't touch the RX please.
I hope this helps.

Hi Bill,
So, filling in more of the puzzle...
The purpose of the NOR and REV positions of the SAT knob are to set how the
rig tracks the Receive and Transmit sides of the rig. This is a great help
when tuning around the satellite's passband, looking for a QSO in progress
or someone calling CQ.
As you know, the Rx setting controls the receive side of the rig, and Tx
controls the transmit side, and the earlier email talks about how to adjust
them to "find yourself". You can, of course, just twiddle the Receive side
of the radio and scan the band, but then when you find something to
participate in, what about the Transmit side? All that work you went
through to find yourself was destroyed the moment you changed frequencies.
Now you have to find yourself all over again, taking time, potentially
interrupting the QSO, or missing the CQ. Wouldn't it be nice if the
transmit and receive sides were locked, so that moving one would move the
other as well? That's what the NOR and REV settings are for.
In NOR mode, increasing one side, moves the other an equal amount in the
same direction. This is for satellites that are "non-inverting" (of which
we currently have none). These satellites use the same sideband on both
uplink and downlink, and increasing the frequency of the uplink moves the
corresponding downlink up the same amount. So, you can see that the NOR
setting will allow you to move the receive side of the rig around, and the
transmit side will follow. Then when you find something to do, you're ready
to go!
The REV setting is used for Inverting transponders. Increasing one side
results in a decrease in the other, again matching what happens with your
signals through the satellite.
So, use the Rx and Tx settings to find yourself in a quiet part of the band,
then flip to NOR or REV, depending on the satellite, and tune around for
some activity.
One final note... Because the Doppler shift is a function of frequency, the
shift that gets applied to the uplink and downlink are different. This
means that over the course of the satellite's pass, the magic combination of
uplink and downlink where you found yourself at the beginning of the pass
will drift apart. This means that periodically you will need to temporarily
move off of NOR or REV mode, back to Tx or Rx (which ever is on the higher
band) to refine your settings. It's a bit annoying, but you get used to it.
Hope this helps. Good luck!

Hello Chen,
Congratulations to the entire team to grab the attention of your President.
We are sure that your President's visit would further boost the
Amateur Radio and Amateur Satellite activities in China. We look
forward to have more amateur radio satellites from China in the near
future.
Wish you all the good luck.

I calculated the altitude of Negai*" using 'Newton solution of
