Hi Todd,
A cheap alternative could be download on your phone/table Frequency Sound
Generator.
Set it to play a 67 Hz tone while speaking, perhaps will do.

Problem solved.
I had to un-install and re-install SatPC32 and NOT restore my data
backup. Something got messed up in there.
So I reconfigured everything and now back to normal.

Thanks for the video & congrats on your project!
But I have to wonder... just HOW MUCH wind would it take to abort the

Content-Type: text/plain; charset=utf-8
I?m new to receiving FoxTelem.
I have it running on a Mac with a Funcube dongle.
The Mac is running High Sierra 10.13.3 and Java 8 update 161.
I have had some success with AO-85 and AO-91 but none with AO-92.
The instruction manual says that I should use Java 6, however this is no
longer available and not supported.
Is it that the instructions are out of date, or can I acquire Java 6 form
somewhere or is Java 8 OK?
Every thing seems to work with the FoxTelem application (Ver 1.06q_m)
Any hints or tips greatly appreciated.
Many thanks

Yes you can add a CTCSS tone generator to almost any radio. I used the
Communications Specialists, Inc. SS-64 to provide a tone for an old ICOM
211. Connect it up the audio chain, say at the deviation pot.

PL tones are called subaudible tones. The freq response of the mic and/or
the preamp may prevent the 67 hz tone from being "heard" by the modulator
circuitry.

PL tone transmit is different than tone squelch. Tone squelch is used on the
RCVR side to squelch out unwanted signals. The radio receives them but they
don't break the squelch circuitry. You may notice a "MON or MONITOR" button
on the radio. That temorarily disables the tone squelch circuit to be able
to check for channel activity.

Hi John,
Yeah, .950 is band center.? I use .920 because I hear that most people tend

That said, your demos are done and I see we did work each other on AO-91!?

/As noted in a previous e-mail, there is usually enough people operating
these birds to keep the transmit window open.
I have recently resurrected, for Easter, an ancient Kenwood TS-9500, a
435 MHz Sat radio. While reading this topic, I suddenly realized that
there was no CTCSS technology in this radio, but I could never tell
while on air, on SO-50, AO-91, or AO-92, today!
This is not meant to discourage people adding the tiny and affordable
CTCSS generator to an older radio. This reflector is a great source of
information to learn and accomplish this? .....it's all for fun?

No, but this link shows that the higher probabilities or re-entry are
between about 38 to 43 degree latitudes north and south.

ation-will-crash-to-earth-this-weekend
Im not sure why those would be slightly higher. 43 degrees is its maximum
excursion (matches its inclination)... Maybe its because as it passes
over the equatorial bulge, it sees the higher drag and that will start the
demise which will occur then 20 minutes later?

You can see the live track of Taengong to re-enter in the next 24 hours on
http://www.heavens-above.com/
Just remember, as it suffers increased drag, it will speed up and be ahead
of classic predictions.
But at least you can see when you are under the orbit as to whether it is
worth going outside. I 'd go out several minutes before the prediction
since we dont know how quickly they are updating the elements as it speeds
up.
and even if it is daytime, you will see it if it comes in in your area...

It is because the amount of time it spends between 38 and 43 is longer
than the lower latitudes.
