Along these lines, I need a new car. My Sonata has 404K miles and I
would like to replace it before it dies.
I'm really looking at the Prius Prime +. Does anyone know if this emits
obnoxious things, and how radio-friendly it is, overall?
Thanks!

It isn't quite cheap, but Pelican makes a wide variety of cases to hold
things. I don't know the geometry of your radios, but I'm sure you
could find a good fit. I too looked for a cheap case to hold some
radios, and paid for it when it bounced down a staircase...

Hi Hans,
as you can see from documents mentioned above, the timing depends on
battery voltage, which selects one of four operating modes, but
basically we are lucky to be in highest mode A which means every 2
minutes PSK telemetry and every second telementry frame is twice longer
and contains also SSTV picture. All of this is overdriven by sunwire
logic signal going low. That means no transmission on UHF downlink after
going in eclipse for maximum of 30 minutes (failsafe timer).
If you will transmit on uplink and your signal will be sensed, it will
switch on the downlink for the next 20s.

Hi all,
after our return from european field day this weekend, we sorted out
through all available receptions of PSAT2 telemetry and SSTV.
As very valuable source we use the SatNOGS observations. There I have
found several passes over US, were PSAT2 was transmitting because it
sensed the PSK signals on uplink, and I have found two stations there
and decoded their calls as W5SAT and K4KDR. Congrats gentlemen! If you
can post the power/antenna used in experiments, it would be very
valuable for us. Therefore we can state, that also the PSK31 uplink is
in great shape and waiting for your further experiments.

Congrats on the success of PSAT-2, Tomas & Ales!
Please note that KC9ELU has activated the PSK31 transponder on PSAT-2 as
well.
As for my setup, the location is grid FM17es (lat/lon = 37.7784 / -77.6093).
PSAT-2's elevation is quite low here, of course. It's been great to see so
many stations work successfully through the 2m APRS digipeater, 2m
APRS-to-Voice engine, and 10m/70cm PSK31 transponder even with the
satellite's low orbit making things a challenge.
On my 10m uplink, I've been running 75w to a MyAntennas EFHW-8010 oriented
South-to-North and located on the North side of my house about 4 meters off
the ground. Pretty much a worse-case scenario for communications to a
satellite so far to my South, I would think. This 130 ft. long-wire type
of antenna was put up mainly for 80m NVIS work but does a great job on
other bands as well. I think I'll put up some kind of vertical antenna for
10m when time permits to see if that improves my coverage to the South.
My 70cm receive setup is better, although I should mention that I'm
surrounded by heavy tree cover. So, except at high elevations, I do much
better in the Fall/Winter than during the Spring/Summer months. The 70cm
antenna here is a Wimo X-Quad on an AZ-EL rotator and benefits from an
SP-70 LNA at the base of the antenna.
The 10m/70cm PSK31 transponder on NO-84/PSAT, and now PSAT-2 is a great
challenge and a lot of fun to work. Let's hope the addition of another
satellite with this capability prompts more people to enjoy it!

Almost have to take a radio with you on the test drive. I found the LCD
screen of my Jeep wipes out VHF if I have an HT in the car. If I have an
antenna on the outside, it?s not a problem. But I didn?t discover it on the
test drive, because I didn?t bother with the radio (and I usually have it
off on a test drive so I can listen to the car anyway). I?m not sure I?d
break it out while the salesman is standing there, but I?d certainly try to
listen in at some point before signing on the dotted line.

Dear All,
I would be grateful if you could send me your regulator position about SDR's
or legal framework in your country about same. Having some discussions with
the 3B8 regulator (right now) about same this may help clearing some issues.

Hello Jean Marc,
I am not aware of any legislation regarding SDR, applicable to FCC Part
97 (Amateur Radio), in the USA. It doesn't matter if your transmitter is
Software or Hardware modulated. (and, when we get right down to it,
software is just a different way to wire hardware components together ..
but I digress)
It is the effective emission that matters. If the transmitted signal has
the appropriate bandwidth and meets the spurious emission limits, then
there is no problem.

Jean, I'm not aware of any country that has legislation specifically
concering SDR's, certainly the UK doesn't.
However, I can see one potential pitfall. The UK permits any form of
modulation (and any bandwidth) to be used, however, in some countries they
mandate specific ITU Emission Designators in the licence.
While on-air there is no difference between the same mode produced by
different means the Emission Designators can be different. An old example of
this used to be F1B and J2B for RTTY depending on whether direct frequency
shift or audio tones to an SSB transmitter were used.
The use of SDR's could theoretically result in Emission Designators that
may not appear in the licenses of some countries

Dear All,
I would be grateful if you could send me your regulator position about SDR's
or legal framework in your country about same. Having some discussions with
the 3B8 regulator (right now) about same this may help clearing some issues.
Thanking you beforehand.
Jean Marc (3B8DU)
