Bill,
About the only thing I know for sure after working sats for a very long
time is that full-duplex is by far the best way to go.
"once I figure out how to tell my xyl I need another radio"
Wait till the XYL wants something like an expensive trip or new furniture
and then throw the radio into the mix. The better option is to buy the
radio on the down low and then in the unlikely event that she discovers it
just try to look pathetic and sort of shrug and mumble some technical
nonsense.

Hi again!
A correction.... the UV-5R I used in the YouTube video I referenced
earlier was set to tune in 2.5 kHz steps, not 2.5 Hz steps.
The Baofeng radios, like those from the other Chinese brands, tend to
have sharper front-ends than the Icom/Yaesu/Kenwood amateur HTs.
There will be moments where the UV-5R (and other Chinese-made
radios) won't hear the SO-50 downlink, if you are tuning these radios
in 5 kHz steps.
When the time comes that we have Fox-1 FM satellites and EO-80,
I don't think it will be necessary to tune the 70cm uplinks in 2.5 kHz
steps. The 5 kHz steps would probably work fine, and this is something
I'll try as these satellites become available for us to use.
73!

Not at all, My first and only antenna system consisted of a homebrew
tracking box with point to point wiring and an old pair of Orbit 360 TV
rotators topped with homebrew yagis with a modest amount of elements.
I'm trying to ressurect it now. My rig was to only semi expensive thing
I had. If you're trying to make me out to be some snob because I don't
think we used the right approach and should have challenged people's
technical prowess, then you're barking up the wrong tree.

Greeting Satellite friends and a happy 4th
-From the moment I worked either it was RS 12 or 13 with 15M up and 10M down
with a Swan 350 and Drake R4A , over twenty years ago. I knew the die was
cast and all brakes were off. The XYL "situation" not withstanding. It took
time but the "onward" trajectory was constatant-VHF/UHF Icom twins, manual
everything. Now with a IC-910, 14 el CP on 2M, 40 el CP on 70cm. Yaesu G5500
az/el Everything computer controled. L and S band complete systems in moth
balls. I still dig for the challenge that started everything. Being of the
digitally challenged group it can be PITA. I consider my crowning
achievement a fully functional capability system with AO-40 (sobsob). Should
in the future we have the wherewithal (money) to get another or similar
AO-10/13/40 up there. They will pour of out of the woodwork, (build it and
they will come). Unfortunately we need the funds before the people. My
potential lottery winnings are earmarked for that. Untill then my friends we
must dig deep and pay w
hat we can. Currently when time permits I will work everything up there,
still learning the digital stuff (not easy). Like my friend Frank (K4FEG)
says, "work-em till the antennas vaporize". The big party line we have with
each other on the satellites is enjoyable and new ops are a special treat.
We all approach this endeavor and some stop where they do for whatever
reason. For the "brakes are off" people it's can be and is a hell of a fun
ride.

I bought a D72A a little over a year ago because it had APRS built-in; this
made it very handy for the balloon-chasing I used to do.
Now I'm trying to set it up for SO-50. I'm successfully putting it into
full-duplex mode - with the 144 Mhz freq (pl 67.0) on the B-band, and the
435 Mhz frequency on A-band. (Duplex cannot be engaged while the radio is
on the A-band.) I'm running into two problems though.
1 ) Whenever I want to change the receive (downlink) frequency because of
Doppler, turning the knob changes the B-band side, the transmit, which is
what I don't want. As it is, since I can't get the 435Mhz to change, this
setting is only going to allow me to hear the satellite mid-pass
2) I had the idea of putting this/these VFO settings - including duplex -
into memories, one memory for each 5 Khz step on receive. When I follow the
manual directions for entering odd splits in memory, whenever I check to
see what's in the memory by transmitting, (it appears) I'm just
transmitting simplex on the 435Mhz frequency; the radio's display doesn't
change (other than the s-meter showing that power is being transmitted).
I'm wondering how others are making their D72s work successfully on SO-50.
Is/are there (a) certain step(s) that I'm missing in order to change the
receive frequency AND enter full-duplex VFO settings into memory
successfully?
Thanks for the help...either replying to the BB or to me personally is ok. (

Hi Philip,
I?ve just gotten used to pressing the A/B switch to toggle the PTT/Tune to
the frequency I want to change. It?s a pain. I usually program in memories
for AOS, AOS+, MID, MID+, and LOS. And, once in a while, I change the wrong
channel or transmit on the wrong frequency. I?ve suggested a firmware
change to everyone who will listen to offer a PTT selection and TUNE
selection so the operator doesn?t have to toggle the A/B; but, so far, no
success.
If the D72A could also have smaller frequency steps and the ability to
select which radio (A or B) was designated for PTT and for TUNE, the D72A
would be a great HT for portable use.
From what I?ve been able to determine, you cannot ?link? VHF and UHF
memories together to achieve the split function you described. This would
be another firmware option that could offer some convenience.
I love the D72A, and, it?s a shame that to work the [flame off] Easy Sats,
it?s easier to buy a $39 radio than to use a very full featured radio.
Maybe if more folks agreed with the suggestion, Kenwood would listen.
I would also like to see a new HT with a Bluetooth interface to allow for
iOS or Android Apps which could remotely change the frequencies or channels
during a pass. This could also allow for audio interfaces for PSK-31, APRS,
Packet, and more.

With EO-80 and the Fox-1 sats, you won't need to press A/B to tune these
HTs!

For Philip and the group,
Here?s the suggestion that?s been floating around since 2011. It stemmed
from a discussion with Keith Pugh, W5IU:
I spent quite a bit of time with Keith Pugh, W5IU, of AMSAT, who also owns
a D72A. We commiserated over the fact that the new radio doesn't allow for
separate PTT and Tune of the A and B bands.
We'd like to suggest that a future firmware update offer
a RADIO MENU Option for PTT which would toggle through: NORMAL,
A=PTT/B=TUNE, A=TUNE/B=PTT. The Band selected for TUNE would be flagged
with the standard solid "arrowhead" and the Band selected for PTT would be
flagged with a "flashing" "arrowhead".
This would allow for easier use of the radio for LEO
satellite work, especially when the download needs to be tuned. Right now,
the operator needs to remember what Band is selected and ensure the correct
Band is chosen before changing the frequency, either via VFO or Memory
Channel.
It's very easy to get confused and change the uplink
frequency and, then, transmit on the downlink. Having separate PTT/TUNE
would make this radio a lot more fun for satellite use.
Maybe someone?s listening out there who could help.

So, none of you has said a word about turning on the "duplex" feature at
all.....do I just need to forget about setting it, and just deal with the
dual VFOs?
Thanks for the great suggestions I've gotten so far. :-)

Bob,
You jogged some good memories here. I remember working the RS Birdsback in
the '70's on Mode A with Inverted Vee's on 10 & 2M and trackingwith a TRS-80
and a freeware program. The Band was often loaded withusers on CW & SSB!!
Mode K was a blast using 10M up and 15M down.The Ruskies made some excellent
satellites!!!! ?Sorry that they're gone.

Greeting Satellite friends and a happy 4th
-From the moment I worked either it was RS 12 or 13 with 15M up and 10M down
with a Swan 350 and Drake R4A , over twenty years ago. I knew the die was
cast and all brakes were off. The XYL "situation" not withstanding. It took
time but the "onward" trajectory was constatant-VHF/UHF Icom twins, manual
everything. Now with a IC-910, 14 el CP on 2M, 40 el CP on 70cm. Yaesu G5500
az/el Everything computer controled. L and S band complete systems in moth
balls. I still dig for the challenge that started everything. Being of the
digitally challenged group it can be PITA. I consider my crowning
achievement a fully functional capability system with AO-40 (sobsob). Should
in the future we have the wherewithal (money) to get another or similar
AO-10/13/40 up there. They will pour of out of the woodwork, (build it and
they will come). Unfortunately we need the funds before the people. My
potential lottery winnings are earmarked for that. Untill then my friends we
must dig deep and pay w
hat we can. Currently when time permits I will work everything up there,
still learning the digital stuff (not easy). Like my friend Frank (K4FEG)
says, "work-em till the antennas vaporize". The big party line we have with
each other on the satellites is enjoyable and new ops are a special treat.
We all approach this endeavor and some stop where they do for whatever
reason. For the "brakes are off" people it's can be and is a hell of a fun
ride.

For a semi-clueless, riff-raff newbie, this has been an enlightening
discussion. I will endeavor to go full-duplex, once I figure out how to
tell my xyl I need another radio. ;-)
