HI,
I am considering a radio change and wonder what price on a used
FT-847 is going for? The radio is non-smoking, good condition but
not mint appearance, fully operational, has been modified for
separate Rx antennas for 2m and 70cm using sma connectors (see my website).
I am considering the Elecraft K3 with dual Rx and would have to trade-up.
Only speculating at this point and the radio is NOT for sale at this time.

It's amazing what a bit of inginuity (and downright tenatiousness
......GM1SXX) can do.
That and a bit of help from my friend Percy ... (perseverance).
When I *RIPPED* down the aerials due to the newly inposed restriction. I
thought my
Anne Logue satellite days were over.
Never having being 'excited' by single QSO FM (on a satellite) I thought
"that's yer lot"
John matey.
However ... hearing such rot!!! regarding the power to work AO-7 (mostly from
the American side, I might add, something I believe is entirely due to Amsat's
FM policy) I decided to see just what 'could' be done.
Having what is now IMHO a worst possible case scenario, that is, 22 year old
rigs
(no CAT interface for doppler tuning), a ground floor flat without access to
loft space, total aerial restrictions outside, surrounded by mountains on 3
sides and a maximum output power
of 5 watts on CW.
I still managed to contact F6 something-or-other this morning. Presumably, my
uplink on AO-7 mode-B was readable to those whom actually have a receiving
aerial because two stations answered my CQ. The 7 element Arrow giving me a
giant EIRP of about 40 watts ... however,
my downlink signal, just 3 elements on 2m, indoors !!! definately left a *LOT*
to be desired.
I could hear myself - but then, I 'knew' I was there. Two stations did answer
but since they both answered at the same time (err ... I forgot, what did you
say full duplex meant?).
I ask because they 'both' continued to reply to La2qaa/QRP ... the only thing
I managed to
copy was de F6 some-thing-or-other ... when I sent an interogatory (QRZ) they
both disappeared.
I waited a while to see if either of them would try again but they didn't.
As I have mentioned so many times before, you really *DON'T* need 10 elements
and an
'effing' *BIG* BRICK to work AO-7 - (or any other of the LEO's for that
matter).
I do apologise for the rather offbeat keying, my keyer is made from 2 x back-
to-back
computer microswitches taped to the palm of my hand ... BECAUSE I WAS WAVING
THE AERIAL ABOUT WITH THE OTHER HAND ... of course.
For bthe affluent on the other side of the pond this weekend, enjoy yout
turkey. For the
'moderately' affluent, enjoy your chicken - for the remaining ... enjoy you
egg.
Happy Thanksgiving.
Relax !!!, the Europeans ... the geese are still getting fat.

Hello The Net:
SINAD is nice because the complete path from RF thru IF thru audio
demodulation can be tested.
Also a cost effective approach, Last SINAD meter I got was about 100$.
It is a HELPER Instruments,Inc. model SINADDER LINEAR 5
SINAD measurements require an external signal generator, and variable
attenuator.
A noise figure meter can usually test the RF path or the RF thru IF
path, but NOT to audio.
For my HP-8970B, the IF would have to be more than 10 MHz, the low freq
end of the machine.
NF meters are about 10-20X $$$ the SINAD meter purchase.
I use my NF meter in a Y factor mode, which is essentially a signal to
noise ratio.
SINAD is also a Signal to Noise ratio, with Distortion taken into
consideration.
(S+N+D)/(N+D). When noise is very low, and distortion is also low, thus
a S/N.
SINAD was used by Motorola and FM radio testing with a 1000Hz test
modulation.
Testing can also be used for testing SSB receivers, using a clean
carrier with no modulation
and tuning the RX for max signal, max S/N, max SINAD reading.
Both instruments have their utility.

I have a nearly perfect Icom IC 820-H for sale. Comes with hand mic and

10. It's in great shape and the only reason I don't rate it 9 out of 10 is
that a previous owner switched out the N connector on the 70cm side for an SO-

list and now I've decided to go to an all in one HF and satellite radio. I'm
asking $450.00 for the radio. This includes shipping anywhere in the lower 48
states.
I also have an Icom AG-35 70 cm receive preamp for sale. I am asking 125.00
for it. This also includes shipping anywhere in the lower 48 states. If
someone would like the radio and preamp both I will sell them together shipped

I can't see any reason you couldn't perform the SINAD on an AM receiver
and probably SSB as well. The point being that when tuning a
preamplifier for the best SINAD are you not accomplishing the same goal
as in using a noise source?

All,
Twenty-five years ago this week, Owen Garriott, W5LFL, made history by being
the first amateur radio operator to talk to hams from space. Owen's
historic flight on the STS-9 Space Shuttle Columbia mission was launched on
November 28 and landed on December 8, 1983. Owen's ham radio adventure on
STS-9 ushered in a host of outstanding outreach activities that continue
today with the ARISS program.
Many will recall that first set of contacts and downlinks with Owen. Those
first contacts allowed each of us to share the excitement of space
exploration through Owen's first-hand eyewitness accounts. Owen's ham radio
legacy enabled space travelers that have flown on the Space Shuttle, the
Space Station Mir and now the International Space Station to share their
journey of exploration. And Owen's son Richard, W5KWQ just a month ago
carried the torch further to become the first 2nd generation amateur rdaio
operator to talk to hams from space. What other hobby, except amateur
radio, could or would open the communications lines of space travelers
beyond that of the space agencies or international heads of state??
To celebrate our 25 years of amateur radio operations from space, the ARISS
team has planned a set of special event opportunities during the month of
December and part of January. A special certificate is being developed for
those who communicate with the ISS, either 2-way direct (with the ISS crew,
the digipeater, or cross band repeater), or 1-way reception of SSTV or voice
downlink. Several events will be described here with several "surprises"
planned over the month-long celebration. The surprises will be announced
once we are prepositioned to accomplish them.
Specifically, the following is being planned in the near-term:
---December 1-5--in addition to school contacts and APRS digi operations, we
plan to configure the radio system for cross band repeater operations. This
will utilize the standard U/V operations in low power mode.
---December 7-12 we will run a test of 9600 baud packet operations on the
simplex frequency 145.825 MHz.
---Given that PCSAT should be in full sun starting December 9, December
14-19 we will switch to 1200 baud packet on 145.825 to support double hop
opportunities.
---And at times, especially during the weekends, you might see some SSTV
operations if the crew is available.
We will provide more updates in the near future. We would like to remind
everyone that ISS flight requirements related to EVA and vehicle activity
may require the radio to be off for some portion of this schedule. And
school contacts and general QSO opportunities by the crew will also preempt
this schedule for short periods of time. (But remember that if you hear
these, you still qualify for a commemorative certificate).
In the meantime, enjoy the ARISS ops on ISS! And congratulations to Owen
Garriott, W5LFL, on the 25th anniversary of his historic flight!!

To All,
If you are using a LNA and you intend to perform a noise calculation,
knowing the noise figure of the LNA is important.
LNA gain can shift the IF pass band in a receiver providing false indication
of noise contribution. In FM receivers it can shift the noise center of the
FM detector.
A noise figure measurement gives you the performance over the bandwidth of
the LNA not the bandwidth of the receiver. Noise tuning using the y factor
and a wide band receiver gives you the best performance of the LNA you have
as well as a means of comparing different LNAs independent of gain.

Go to eBay and search on FT-847 to see the Buy Now prices. If you are an
eBay member you can do the same search based on previous transactions and
see the final price on completed auctions.
