I use two Baofengs and an Arrow antenna on those satellites. For SO-50 I
have been using the Arrow diplexer as a bandpass filter between the 70
cm antenna and the 70 cm receiver. (Got that tip from someone on this
list.) I can't say that it's 100% effective, but it works most of the
time to give me duplex.
If you already have the diplexer you may want to try that before you
shell out for a new radio.
On the AOs I generally don't have a desense problem with 70 cm transmit
and 2 m receive. The radios are Baofeng UV82.

The only full duplex radio on the market that doesn't desense* on
SO-50 is the Kenwood TH-D72. There are several out of production
radios that also work with it, like some revisions of the Icom IC-W32.
*I have a TH-D72 and I find I intermittently experience some desense
when I use full power. At low power (500 mW I believe) I never
experience desense. I know of one other person who has this problem.

HiBMW sez,

If they can't fix the noise, they have pretty low standards, IMHO.

It doesn't matter what their standards are - if they are manufacturing
products that emit harmful interference - it's on them to fix it!! BY

Kees, the Kenwood TH-D72A does SO-50; very well. I know it is expensive, but
you get what you pay for. It will also send and receive packets to and from
the birds, which I am learning to do. You have a great signal on the birds.
If you ever get a D72, I will help you set it up and learn to operate it. I
love mine.

I did some measurements on a 2011 Nissan Leaf while charging. The LED
lighting on the wall and disco ball motor directly above the car was
significantly louder than the noise from active charging (on 2m). The LCD
screen on the charger on the wall was somewhat noisy, but not as bad as the
LED lightbulb.
Similar results while driving around as a passenger. It's pretty quiet.
Haven't checked other bands yet while riding around.
Looking around for other cars and I found that my sewing machine is very
bad on 2m. Not much of a surprise given the type of motor involved, but
caught me off guard since I was focused on the garage and not the sewing
room!
The rise in the noise floor is death by a thousand cuts.

Indeed. Many semiconductor manufacturers who are concerned about meeting
FCC spurious emissions for non-intentional radiators will include a
"spread spectrum" option to dither the clock.
One has to ask: "If I took some fresh cow manure and spread it over your
dinner plate thinly and evenly so that you could not see it, would that
be better than just having it as a pile on the plate?"

Sorry, PSAT2 auto-reset back to safe mode because we did not get the
"we're still here" command uplinked in time.
Only modes available are PSK31 and SSTV.
We will try to restore normal operation on the next several orbits.
Normal mode should show status bits of 01000111.
Which has PSK31, SSTV, plus Digipeating plus APRS-to-Voice

AMSAT Rovers:
We desperately need 2 APRS Mountaintop weekenders for 4 hours on Saturday
20 July for the Annual APRS Golden Packet event from Maine to Georgia along
the Appalachians. Goal is APRS messages the full length and into Canada.
One needed station is in SW Virginia on top of Comers Rock near Wythville,
VA and one in Northern Va on Hawksbill Mountain east of Harrisonville, VA.
All of the other 15 mountains are signed up.
It is a 4 hour event 11 AM to 3 PM. Both of these sites are drive-up
except for the last hundred yards or so to the best operating position.
http://aprs.org/hamtrails/comers-rock.html
http://aprs.org/hamtrails/hawksbill.html
Prove your APRS stuff! And enjoy the view and drive!
Full event details: http://aprs.org/at-golden-packet.html
PLUS, we will attempt PSAT2 relay on 3 passes during the event. All others
hold off please.
