Sorry, in this time of my life, retired now, it is so far out of reach -
Icom hasn't noticed the cheaper-work better- radios coming out of China...
My set up for HF and Satellite use with my monies into antenna systems and
preamps outperforms these overpriced rigs. Besides, No HEO birds in the
near future and if the manufacturers don't see that on the horizon, they
will leave that area void of announced moderately priced equipment for the
mainstream hams.
No, I think the IC-9100 is a great rig, just not affordable by "Joe" ham.

The Icom 9100 isn't overpriced at all considering all it does. If all you
want to use it for is the satellites, there are cheaper alternatives.
However, it also does true dual receive on HF (something the Yaesu FTDX5000
and Icom 7600 don't do), it has the roofing filter options for increased
HF/6m performance, plus several other nice features. If you want a good,
high performing HF/VHF/UHF rig, it is a great bargain.

Jerry provides a more complete review and more
depth (based on his having experience with more
satellite capable radios). I should have
mentioned the FT-837R, as it was the "best"
before the advent of the new HF-light radios. I
traded all my components for the single radio
concept when I bought the FT-847 (too soon after
its introduction), but it has done very well. I
am still flip-flopping on whether to sell the
FT-847 as it is still good for satellite use (and
432-eme). But my station is building up around
the Elecraft K3 as core so we will see.
I do question everyone's desire to have 1.2 GHz
in the same box. Experienced microwavers all
know that there is a lot of desirability to
locate mw units near or at the antenna. This
becomes a fact above 1.2 GHz where coax losses
eat you up. My FT-847 operates on 2m for 1268 by
using one of the (rare) DEMI 144/1268 Tx
upconverters. It's not installed, at present,
since repairing wind damage from last fall, I put
up a reduced-saze array (still not fully
functional). That unit produces 15w with about
1.5w drive on 144-MHz. It was produced for a
short time during AO-40, and sales ended with
AO-40's demise. I installed it on the elevation
crossboom with 7-8 foot of LDF4-50 (1/2-inch) hardline to the loop-yagi.
Today, one would have to purchase from db6nt
(Kuhne Engineering) at higher cost (I think there
might be a couple other sources for such a
critter). So that gives the Icom and Kenwood
radios an advantage (of sorts). But to get any
reasonable RF to the antenna you will be running
hardline, and if used for 1296, a remote
preamp. Well, for satellites you should have
remote preamps, anyway (this last advice is not
directed to the hand-waving Arrow/HT crowd).
There debate will continue as long as hams have radios ;-)

When SO-67 isn't operating in amateur mode is it on a different frequency.
If so, what frequency is it and what modulation scheme is used?

Hello Everyone,
Here is some information for those of you within LEO range of the Marianas
Islands. This appeared in the DXNL 1726 - May 4, 2011 DX Newsletter ... a
free and weekly service of DARC Committee "DX and HF contesting"
(http://www.darcdxhf.de).
If I waited for this week's ANS news cycle the DX opportunity would be over
... here it is in case you can use it ...
KH0 - NORTHERN MARIANA ISLANDS, OC-086
Yoshi,JJ8DEN, appeared on the bands as KH0PR and will stay in the
Coconut Village Hotel on Rota Island (OC-086) until May 8. He works
in CW, RTTY and PSK on 160m-6m and via the satellites FO-29 and VO-52.

Neat!
As I understand it, the JA's do not use Mode B on AO-7 because of a
perceived issue with the uplink being outside of the post-launch
satellite bands. However, Yoshi would be legal to use Mode B on AO-7
under his KH0 call as I see it. Our FCC waiver for AO-7 Mode B is still
in effect. That may give him a little more DX if he will try it.

Hi Werner, HB9BNK
I have seen your measurement on spectrum analyser with and without the
passband cavity filter but the result is not satisfactory because you need
to add a notch cavity filter tuned to suck the - 20 dBm offending POCSAG
signal at 147.300 MHz
By the way you can solve the problem using a less know "Front End
Crystal Antenna Filter"
The above filter is a passband filter to be placed between the antenna
and the preamplifier input and it's passband is very sharp and narrow
and only flat for about 30 KHz after that the responce belove and upper
the passband drops down for about -60 to -70 dB
For example you can order a passband from 145.925 to 145.955 MHz
or from 145.955 to 145.975 MHz to work OSCAR-7
You can install the filter inside the SSB Electronics preamplifier between
the input coax relay and the gate of the GaAsFET and this allow you to
transmit in 2 meters because on transmit the crystal filter is swithed OFF
from the TX line.
Alternatively you can place the crystal filter at the antenna but outside
the preamplifier on a PCB into a separate box with two coax relays in
order to switch OFF the filter with the purpose to transmit and to receive
the full 2 meters band.
There are many manufacturers as you can see on Google searching with
"Front End Crystal Antenna Filters" but they must be ordered on request
and specifications of the customer and I believe that it is a difficult task
to get only one prototype.
In your situation I suggest you to call by telephone Mr Barkoviak at
the SSB Electronic factory because he know many crystal manufacturers
in Germany and I am sure he can order the filter for you under your
specifications.
I know Mr Barkoviak very well and he has ordered many not standard
crystals for me to be used into my SSB Electronics converters and
transverters.
In additions I am confident that Mr Barkoviac will be interested to
know the results of your experimentation using his SSB Electronic
preamplifier.

Hi!
On Saturday morning, 7 May 2011, I will be at the Cochise Amateur
Radio Association's annual Larry Warren Hamfest in Sierra Vista,
Arizona. This is a half-day event, and more information is available
at:
http://www.k7rdg.org/
I will have an AMSAT table at this hamfest. WD9EWK will be on
satellite passes throughout the morning for demonstrations,
transmitting from grid DM41vm.
After the hamfest, I am thinking of making a drive toward either
the DM51/DM52 grid boundary northeast of the hamfest site or possibly
the Arizona/New Mexico state line along the I-10 freeway for some
passes in the afternoon into the early evening before driving home.
I was just at the DM52/DM53 boundary in late March, so I probably
won't make another trip up there - unless I decide to take the
really long way home from southeastern Arizona. I will have my
TH-D72A transmitting my location via APRS as WD9EWK-9 when I drive
to Sierra Vista on Friday evening, as well as anywhere I go on
Saturday. That should be visible at (among other places):

As always, I will be happy to send QSL cards to anyone who works
WD9EWK on Saturday - at the hamfest, or anywhere I happen to stop
after the hamfest. Just e-mail me the QSO details, and I will
send a card if you're in the log. No need to first send me a card
or SASE. I will also upload my log to Logbook of the World, for
those using that system to gain contacts and grids.

Ed,
I have not done it yet, but the parts are in the shack:
I will be installing two buffer IF amps on the IC-910H. These
will feed my SDR-IQ (main and sub rx) . This was my original thought.
However, I also ordered a FM filter for my K3, and I will simply have
the K3 monitor the IF tap of the main receiver of the IC-910H. One
annoyance to me is the +/- 1 kHz RIT of the IC-910H. Not good enough
when chasing some non computer assisted folks on the birds (ssb/cw).
With the K3, I then would have essentially an unlimited RIT just from
the tuning control.
There, now that I explained it, I had better warm up the iron right?

My vote is for DM 51/52...don't have either one of those yet!
Thanks Patrick!

Hi Werner, HB9BNK
In addition to my previous message I found that KVG in
Germany make "Frontend " crystal filters upon customer
specification in the range 100 to 200 MHz. The only problem
is that they are large and flat only +/- 7 KHz (14 KHz total)
and the insertion loss is 7 dB
http://www.kvg-gmbh.de/8.0.html?&L=3
Since the gain of the SSB preamplifier is about 20 dB you
can try to use the above filter for a test between the output
of the SSB preamplifier and the input of tranceiver IC 910H
In this configuration the gain of the preamplifier will be
reduced only by the filter insertion loss of 7 dB but having
available about 13 dB of preamplier gain the overall Noise
Figure of the receiving system will be not deteriorated.
If all goes well and the preamplifier is not overload by the
POCSAG 147.300 MHz signal you can order four crystal
filters to cover about 50 KHz to work OSCAR-7
By the way I believe that the above crystal filters are very
costly and that two huge cavity one connected as passband
filter and the other one as notch filter is less expensive for
you and this is exactly what I did in my 2 meters receiver
system using both cavities after a high dinamic range Norton
type antenna mounted preamplifier to clean up the garbage
at 145.200 MHz in my location.

I did not hear SO67 at 0115z. It was scheduled to come on at 0110z. Can
anyone confirm that it was NOT on?

I got a note from the command station that the first three passes for
the 4th got missed...the following passes should be on.
Sorry.
