Did I hear someone was looking for the schematic for a ICOM 7000 and the
pre-selector? If so, I will be happy to send a copy.

We were discussing a Giga Ethernet OZY back in May of last year. Here is a
chip to look at:
<http://www.asix.com.tw/products.php?op=pItemdetail&PItemID=88;65;102&PLine=

Opencores.org has a 10/100/1000 Ethernet core also.

It would be nice to have the extra speed available, although 100Mbps should
be sufficient for most needs. A cost analysis would be a good idea in any
case, then we can decide which is the best way to go. I for one would be
more interested in a network interface than USB, because of space
limitations in the shack. That would allow me to put the interface in a
more accessible place too (access for antennas is separate from access to
actually use the gear!). Only the LAN reaches all areas here. :)

One major advantage I see with ethernet is the galvanic isolation. This
would decrease the common-mode noise between the computer and the radio. One
could also use a media converter and run a 100baseF fiber link to the RF
unit installaed on the antenna mast.

With my shack layout, 100Mbps Ethernet is a better option than USB, because
it means I don't have to cram the PC into a tiny space. Worst case is to
run a Cat 5 (or 6) cable around the place. :)

Folks
While reading the guy's Thesis about GIG Ethernet on page 22 I saw the frame
structure, which looked a lot like the old familiar AX25 thingy I saw long,
long ago.
So I drug out a hunk of hardware and took some pictures: (Yep I was N4CI at
the time)
http://www.hamsdr.com/personaldirectory.aspx?id=521
This was Lyle Johnson's wonderful creation. Serial Number 250 which was the
first production unit of the TNC-1. Lyle borrowed and offered up a year of
his salary to produce these kits which I believe put TAPR in the lead of
technology. The front panel is my creation, but Lyle made it all possible
and started a revolution. This unit was the 2 meter side of the N4CI 20
meter Gateway using a Xerox 820 and an FT 980 transceiver in an "RLI"
gateway. BEFORE the FCC shut us down. It's line mate SN 251 became the KF4JJ
digipeter at the 950 ft level on the WXIA Channel 11 TV tower on Moorland
ave. in Atlanta! If you have never experienced the thrill of riding a one
man 27 mhz controlled elevator up 950 ft you are in for a treat! At least I
did't have to climb it, but sometimes the 27 mhz signal was not heard at the
base and the elevator didn't move! 1000 ft of cable blows in the wind and
jinks the box 2 ft at a jerk! I guess I was the jerk, but it was a hell of a
lot of fun! I was amazed that takin' a piss from 950' went a whole three
blocks! (Ahhhh Youth!). One time it rained at the top and not at the ground!
Lightning was a thrill, as was 273 KW erp 50 ft away! There are probably
many other linemates on abandoned firetowers moldering all over the state of
Georgia!
Lyle! Thanks for bein here after all these years! Still pushing the state of
the art! Still ensnaring folks like Warren! Still working 'at the edge, and
making it rewarding for followers like me'. Also to the Phils, Bills,
Jonathans, and other contributors here, who keep ham radio Young!

Part of the idea is to be free from a local PC and free from USB. We'll
probably need the FPGA fabric since a configuration with this board probably
wouldn't have an Ozy. I didn't mean to restrict it to the same I/O
configuration as Ozy (e.g., a port designed to drive an SDR-1000).
> One thing about a Gb Ethernet board, it's not going to be simple.
If a Xilinx Virtex-4FX were used as the core processor and FPGA, reference
designs exist with 1 Gbps Ethernet. I suspect one of these could be
leveraged (e.g., Avnet's DS-KIT-4VFX12LC at http://em.avnet.com).
Of course, the PowerPC cores in the Virtex won't run WindowsVista, but might
run MontaVista :-)
Neither simple nor cheap, but perhaps interesting?

Have you folks considered the RFI aspects of Ethernet? I just finished
switching my home lan to 100% wireless due to the awful noise my twisted
pair setup was causing (20 over s9 signals every 60 Khz). Personally, don't
think 10/100 twisted pair Ethernet belongs anywhere near a sensitive
receiver.

Speaking of noisy Ethernet, does anyone have a good source for shielded LAN
cables (RJ-45)?
I have a lot of my segment shielded, but I am having a hard time finding
more shielded cable.
The local stores, even the geek hang-out, only carry unshielded.
I am not thrilled with the idea of buying Category 7 cable to get shielded,
especially when only half of the pairs are used.
If I can't get economic pre-made cables with a shield, how about a good
source of two-pair, individual shield cable? I would be willing to crimp
the RJ-45s on.
I'm using some nice Belden individually-shielded TP with Datalene for a 150
foot buried run between the houses, but that was a pull-out from work, and I
don't want to pay $1+ a foot for cable.
Mike - AA8K
Oh, I even replaced all of my TelCo and alarm wiring with shielded. At the
RJ-11s I add a clamp-on Ferrite on the cord to the phone.
My previous house had coax for the electrical power wiring. I'd never seen
that style before. The neutral was stranded and wrapped around the hot
wire. It was nice and quiet. Sure beats the knob-and-tube we had when I
was on the farm. We were in a TV fringe area and I had quiet hours from my
folks. My mom's sewing machine RFI got me back for my TVI. Then there was
the neighbor's electric fence...

Don,
Gee, I don't see that, and I have 100BT run all over the place. What
frequencies did you see that on?
My Dipole is right over the house as well. I do see some spurs, but nothing
like that strong!

I haven't had that problem. I have had RFI from PCs and monitors, as
well as from cable Internet providers, but not Ethernet. One could
argue against having PCs next to sensitive receivers (Oops, did that
just kill off the SDR?)... ;)
Obviously, there will be some setups that cause issues, whatever
combination we use (even the humble incandescent light bulb has been
known to cause RFI in rare cases). If your setup is one of those
problem cases, then another method has to be used. It's like my
setup which isn't conducive to having a fast PC next to the radio due
to space constraints (and the distance required is several times the
maximum length of USB), so I would be interested in a network
interface of some kind. Yes, I could stuff a PC in... somehow, but
it would be a major undertaking, unless it's something with a very
small footprint.
It would be nice to have horses for courses. :) USB for those with a
local PC, Ethernet for those who need a networked radio (hmm, that
adds all sorts of possibilities!).

Hi All
I've been doing some thinking today about a couple of side projects
that I think would benefit the SDR community. Let me run them past you.
1. Define a network protocol, or take an existing one, for moving audio
data between separate machines. This would allow for using (say) WSJT
on a different machine to the SDR DSP processing. Such a protocol
should include a negotiation system so that sample formats and sample
rate information can be passed before the actual data. For use on a
LAN, UDP would make sense for the audio data itself. As well as
individual programs supporting it, a plug-in for Jack could also be
written to use it.
2. Define and produce an open-source digital audio system. I am fearful
that a proprietary system will eventually become the standard, and that
isn't in keeping with ham spirit (IMNSHO). I'm sure we can find an
adequate open-source codec (Speex?) and cross platform libraries exist
so that producing software for all of the major platforms would be
relatively straightforward.
I would happily help with such projects, and surely there must be some
developers out there that want to contribute to moving SDRs and amateur
radio in general, forward.
Comments please.
