I'm in the process of acquiring a pair of U110 TV style rotors that have
been configured for use as an AZ-EL system. Currently, the rotors have

I have one, and it works very well. The SWR, measured with a Bird wattmeter, is

Hello,
About the future HamTV experiment, is it possible to use a cheap RTL DVB-T
dongles used or RTLSDR to receive such signals with proper LNA and
downconverter. If the downconversion fits the signal on a proper channel does
it device is capable of decode the transmitted format???
Thanks,
Hi Raydel,
I stand to be corrected but a these dongles are specified for DVB-T so I
dont think they would work for signals using DVB-S modulation.
The signals from the ISS will be at 1.3Msps or 2.0Msps - I believe that only
the Technotrend T1600 and T3200 cards have, so far, been identified
OK, I see,
Well, it would be out of my reach.
Thanks for the info Graham!!!

this in a while my last experience with a non-FM bird was AO-40.
I'd like to avoid the futility of the FM LEO's on FD, and look to the
working passband birds, which I understand are AO-7, FO-29, and VO-52.

Hello Domenico,
In reply to your inquiry:
I am interested to know if someone in BB has used
or is using the actual Amateur Satellites during the
emergency occurred in Oklahoma and Texas because
of the actual tornado's.

Well after working for a very long time without issues my LVB and Yaesu
control box have stop talking. The rotor box works perfect with the rotor
but the LVB display does not indicate any movement. It just sets at 179
Az and 0 El. The switches on the LVB will move the rotor but no

Hi Ben, N1WBV
I disagree with you because the LEO satellites are built by AMSAT to serve
also into the emergency.

Hi Tom, W9KE
In responce to your sentence..Add the chaotic single channel nature of
the FM sats and you have an even harder sales job on your hands.

Hi Trevor, M5AKA
I agree with you.
I remember that only the HEO satellites OSCAR-10,OSCAR-13
and AO40 were used during the emergency when necessary.
My opinion is that we satellite operators we are not actually
organized to use the LEO Amateur Satellites during the
emergencies so that we only

You will get better answers from other people on the list, but a couple of
things come to mind:
1. Do the meters still work on the Yaesu G5400B control box? If so, the
potentiometers and wiring between the Yaesu control box and the rotors are
probably OK. If not, check for broken or
Hi JoAnne, K9JKM
If the 2-meter and 440 MHz repeaters are destroied by tornado
the amateur satellites are still in operation and are useful if we are
organized to use them.

Bill,
You are approaching Field Day the correct way: Concentrate on the analog
transponder birds (FO-29, VO-52, AO-7, in that order) and don't even try
making a contact through SO-50 (the only FM sat currently working).
The FT-847 and Arrow antenna should work fine. The preamps are not
There's also an article in the June QST which answered a lot of my
questions about setting up for and operating sats on Field Day.

Domenico,
With all due respect, you base much of your
argument on a single sentence on a marketing web page.
The emergency access ability may have been
used as part of the justification for funding
or launch vehicle access; it doesn't mean it works for that
in any practical situation.

I wish they had just skipped the FM-LEO aspect. They will just be plain ugly on
Field Day and not show this aspect of the hobby in a good light.

You're definitely approaching it in the right way, Bill!
An FT-847 is an excellent satellite rig, and in combination with a small
gain antenna, will be an excellent station.
The 50 Watts the '847 provides is more than enough RF power, even with
the Arrow, or similar Elk, antenna.
