Also, my experience in past years was that there was no shortage of
capable mode-L operators. Hoping I can get in this year.
Thanks for doing this, Drew!

Thanks Patrick, Robert, and John
Patrick, the former is pretty much what I've been doing at demos. A fairly
large unpowered Radio Shack speaker with a long cord, plugged directly into
the D72's output jack. I then point the speaker away from me and stand
several feet away and use the D72's internal mike, full duplex
.This has worked well for the audience being able to hear. No feedback
problems reported yet. I would like to be able to hear better though, hence
the point of my post. ;-) I think I've only made a couple of Q's for this
reason.
I'll check out the Amazon link. I think Fry's Electronics may have
something similar. (I need a good reason to go to Atlanta anyway <grin>;
Ham Radio Outlet is only about 5 miles away from Fry's). I'll look for a
Bluetooth speaker like you described too.
John, come to think of it, you did tell me - and sent pics - of the adapter
you made using the resistors . (The plug was from a TI calculator, I
think.). I'll have to look for that email
Robert, the clip on speaker idea sounds great. Did you use it at the AMSAT
Academy demos?

Hi AMSAT,
There is a launch this Monday night (EDT) with quite a few satellites in
the amateur bands. KD9KCK has been keeping track of details.
https://community.libre.space/t/falcon-heavy-launch-2019-06-24/4042.
Bill Nye has LightSail-2 as well on 437.025 MHz!
My team could certainly use some help tracking the E-TBEx satellites.
These satellites will be exploring ionospheric disturbances with phased
locked transmissions. Details are here:
http://exploration.engin.umich.edu/tbex/. The orbit inclination is low, ~
18 degrees, and those of us up north will have a hard time tracking it.
TBEx-A @ 437.485 MHz
TBEx-B @ 437.535 MHz
If you're interested in tracking, please let me know!
73,

Philip,
I used an adapter from Fry's Electronics for a long time, with
a 2.5mm stereo plug on one end and a 3.5mm stereo jack on the
other:
https://www.frys.com/product/601036
It stuck out of the side of the TH-D72 over an inch, and
with a cable I think it put extra stress on the radio's speaker
jack. I found the right-angle plug with the short pigtail, and
I can run the pigtail under the strap from the SC-55 soft case
that goes over the top of the radio (or under both of those
straps, across the top and on one side) to lessen the stress on
the radio's speaker jack.
Be careful with the selection of adapters for the TH-D72's speaker
jack. Some have enough metal and plastic around the plug, where
those adapters won't stay plugged into the speaker jack. The one
I listed from the Fry's Electronics web site above was the best
of the few I originally tried with my TH-D72, and stuck with
until I found the Amazon adapter with short pigtail and right-angle
plug I referenced previously.
With an extension cable, I can have my speaker about 15 feet away
from me, but usually am somewhere between 5 and 10 feet from it
when I do demonstrations. Even at 10 feet or so away, I can get
audio feedback if I transmit with the speaker firing at me, but
5 to 10 feet is usually far enough where I can avoid the feedback.
An amplified speaker may be what you need to get a little more
volume, without running into the feedback issues. Places like
Fry's Electronics should have a selection of those speakers, as
would online sources.
Good luck, and 73!

We notice PSAT-1 (currently in SAFE mode) is staying up for hours through
a full cycle of telemetry T#999.
So, we are hoping to turn on its DIgipeater for Field Day today.
When the DIGI is on, the callsign changes to PSAT.

On the official ARRL VHF/UHF info sheet
(http://www.arrl.org/files/file/Field-Day/2019/2019%20Above%2030%20MHz%20-%20R
ev%20A.pdf)
they suggest that for satellite QSOs operators should only adjust their
receive frequency regardless of whether it is VHF or UHF. I thought
standard procedure was to adjust the higher frequency whether it is
transmit or receive.

The ARRL can't even get frequencies correct so it's no surprise they are
wrong about which frequency to adjust.
If you aren't using computer control to be able to adjust uplink and
downlink you adjust the higher of the two frequencies.
