I already own a set of baofengs and an arrow antenna . I split the rx/tx.
Should I be utilizing a duplexer on the receive regardless of this fact?
Thank you to all who have commented so far. You have presented additional
things to consider that I would not have known otherwise.

NO-83, NO-84, and AO-85 were all launched as secondary payloads on

CelesTrak uses Space Track as its source, it won't have them either).

Hi Oliver.
This problem with the baofeng affect us only on the case you have a 2m
uplink; if you have the case you may want to put a duplexer (or a LPF
for 290Mhz) on the TRANSMIT radio in the side of 2m as close to the
radio as possible, this will considerably attenuate the 3rd harmonic on
70cm.

Mentioning that you are waiting for a tax refund makes me think you are
planning to dive into SDR with a fairly high-end and expensive unit, You
can probably get away with spending $25 or so if you have reasonably modest
expectations. Noo Elec makes a whole line of SDR devices, from inexpensive
dongles to the pricier (but well worth it if you have the passion) HackRF
unit. Take a look here:
http://www.nooelec.com/store/sdr.html
There are some dongle vendors who sell junk. the Noo Elec units are high
quality. Of course, take that recommendation from someone who owns one of
their dongles, plus HackRF Blue board (clone of the HackRF and virtually
unobtainable now), and a Flex-1500.

Hi Folks,
I have just set AO-73/FUNcube into permanent transponder mode. Plan, as
usual, is to switch it back to education mode on Sunday PM UTC.
Enjoy the transponder and have a FUN weekend.

Hi!
I have been using SDR receivers as part of my satellite work
for a little while now, and have used (or tried to use) a
few of them...
"RTL-SDR" dongles (the $20 or so dongles)
FUNcube Dongle Pro (original version)
FUNcube Dongle Pro+ (current version)
SDRplay
HackRF (One and Blue versions)
The RTL-type dongles and the FUNcube Dongle Pro (not the
Pro+) lack front-end filtering, which rendered them useless
when I tried to transmit with either an HT or FT-817 in
close proximity - even with there was a diplexer in front
of the SDR devices. These devices would basically shut down
until I ended my transmissions, when they would resume working.
The newer R820T2 type of the RTL dongles may have better
stability, but they all seem to lack front-end filtering that
would be desired when working our satellites.
The FUNcube Dongle Pro+ and SDRplay work well as the downlink
receiver when I have worked satellites. These devices cost
more than the RTL-SDR dongles, but they come with front-end
filtering that helps greatly when they operate near your
uplink transmitter. I have had success with both of these
devices, along with HDSDR (the Windows software I prefer to
use when working satellites with SDR receivers) running on
a laptop or small Windows 8.1/10 tablet. I currently prefer
to use the SDRplay as my downlink receiver when I am working
satellites, but will occasionally use the FUNcube Dongle Pro+
from time to time. The SDRplay currently retails at US$ 149
from either HRO stores or the www.sdrplay.com web site located
in the UK. The FUNcube Dongle Pro+ costs around US$ 190 to
US$ 200 including FedEx shipping from the UK, depending on the
exchange rate.
The FUNcube Dongle Pro+ is supported by the FUNcube Dashboard
software for FUNcube satellites like AO-73, and the FoxTelem
software for AO-85 and the upcoming Fox-1 satellites. If I use
my SDRplay to decode telemetry, I would need to pipe the
received audio through a virtual audio cable into those
programs before telemetry can be decoded by either of those
programs.
I have both the commercially-made HackRF One and the crowd-
funded HackRF Blue devices. These are broadband transceivers
that are capable of receiving at bandwidths up to 20 MHz. I
have not tried using either of these when working satellites,
mainly due to the lack of front-end filtering in these devices.
HDSDR only supports using a HackRF device as a receiver, and
I have not tried using either of these as a transmitter. The
HackRF devices are capable of transmitting at low-milliwatt
ranges across the spectrum they cover (officially 1 MHz to 6
GHz, but many have been able to lower the low end of that range
to 100 kHz or so). The HackRF One retails at around US$ 300,
depending on which reseller you buy from.
My recommendation would be to go either with a FUNcube Dongle
Pro+ or SDRplay. Both are in the same price range, and work
well as part of a station for working our satellites. These
may cost a lot more than the cheap RTL-SDR dongles, but it
is better to know the limitations of the low-end devices up
front, instead of getting frustrated with them later on. The
cheaper dongles can work well for receive-only applications,
provided you are not near strong sources of RF (including
your own transmissions), but I think the FUNcube Dongle Pro+
or SDRplay would work well alongside the original poster's
FT-857.
Now if there was a software-defined transceiver capable of
working our satellites full-duplex, without the need for
upconverters/downconverters/transverters to cover 2m and 70cm,
I'd be interested. Until then, I am OK with using an FT-817
(or similar radio) with an SDR receiver and software running
on a tablet. I wrote articles about using these SDR devices
with Windows tablets that ran in the AMSAT Journal and
AMSAT-UK's OSCAR News in the past year. Those articles are
available in PDFs from my Dropbox space:
http://dropbox.wd9ewk.net/
(go to the Articles folder, then look for the files with SDR
in the file names)

Sure makes me want to have a fixed location station, but
given the condo life and that I?m effectively roving from
my deck or my driveway (as well as the fun places I get to
travel to, my 3 part (FT-530, Arrow and Peltor headset)
full-duplex station is just what I need.
When I figure out how to make the borrowed Flex-5000
work at home, I?ll go linear - or if I win the PowerBall.
[Hardest part is using a SDR computer in outside in the
sun.]

Doug,
I have a similar situation - I live in an apartment building here in
Washington, DC, and when I wanted to get on the satellites, I had to
figure out how to do it where it wouldn't take any time to setup and
take down a station between passes. I now have a large DSLR camera bag
fitted with shoulder straps carrying 2 Yaesu FT-817s, preamps, a voice
recorder, Two MFJ diplexers for filtering on both transmit and
receive, a Microset VUR-30 amplifier, and a 5100 mAh 3S LiPo battery
to power the amplifier. This gives me a satellite station capable of
20-25 watts output that is completely carryable. When I want to work a
pass, I just grab the bag, put it over my shoulders, grab the Arrow
and step out onto the balcony or head outside. In the absence of
obstructions, this station is capable of working any LEO satellite
horizon to horizon.

Like others have mentioned here, the $20-25 RTL Dongles have not worked
very well for me when combined with a transmitter. The FT-857D/FUNcube
DonglePro+ combo worked well for me. Not one of the two RTL dongles was
suitable for regular use. I rank the RTL's as a failure for both mode B
or J birds without significant additional filters. For simple receive
use, they're okay.
If compactness was a desire, the FCDP+ would be my choice. However, the
SDRPlay mentioned has a lot more bandwidth capability and is reasonably
priced from HRO in the states.

very interesting discussion.
Does anyone have any first hand experience using the Airspy SDR
http://airspy.com/
It is in the same price range as FCDP+ and a bit more than the SDRPlay.
There are so many to choose from with prices all the over the place. I
realize that you get what you pay for but sometimes that is not always
obvious, for example the HackRF devices are considerably more the
SDRPlay/FCDP+/Airspy but as someone commented, lacks front end filtering
making them a poorer choice.
So far I have been only dabbling with receiving the many satellites now
flying about. It has been a long time since I have made any contacts
through any of them, that was back in the OSCAR 7/8, RS10/11 era.
cheers, Graham ve3gtc
