Quite true Gary.
There are a whole lot of situations that can mess up things for everyone, and
the poisen pill does not have to be directly on site to be the problem.

My repeater group is considering building split-site 6m machine. As an
inter-site link, I was thinking of using some sort of VOIP arrangement via the
internet. I'm curious if anyone has tried something like this:
My idea is to use a point-to-point, private link (i.e. not IRLP or Echo) to

In general VOIP as an audio link is not very stable if you
do not control the bandwidth loading of the Link. There are
technologies like TDM over IP that have much less jitter and dropout
issues.. but it still is reliant on the IP link being stable and not
overloaded as well as
Order up two of the RLC DSP-404 controllers and you will have it linked via IP.
I am using one at the repeater site and another for a voted site and works
well.

You might want to look at my project called thelinkbox. It's an open source
multiport repeater controller/VoIP app that runs on Linux. Although it can work
with both EchoLink and IRLP it can also to be used for private off grid
networks.
The delays inherent in VoIP linking will drive you
In the KISS mode, here is a simple solution that can be used for a trial. At
the receiver site, use a PL decoder to gate audio into a SKYPE port on the
computer at the receive site. Audio would only be present if the receive
signal had the proper tone present.
At the transmit site, use a
No, you're not off your rocker. :)
There already exist off-the-shelf commercial boxes that do what you are looking
for.
One is made by Omnitronics www.omnitronics.com.au and is their IPR100. You'll
need one at each end, and they are in the $1k range per box.

Hi Brian.
The software you need is SvxLink.
It is FREE to download and has all the features you need, and a lot more.
In SvxLink you can use the remotetrx function to split RX's and TX's (yes
multiple!) between different QTH's. The built in voter can select the best
RX. Several codecs are
Maybe it's just me, but this comment is a real stretch.
Even if you have free IP connections at both ends, you're still going to
spend $1000 for hardware on one end?
Worst case, if you spent $100 for a radio, $100 for an antenna, $100 for
feedline and another $100 for misc. connectors, etc.
Brian, you've received lots of interesting suggestions. My only contribution
would be that in the configuration you originally proposed, (and many possible
combinations of the technology suggested by others,) you want the controller at
the transmitter end.

I suspect you could use this for your needs:

and a USB-equipped Linux capable system - doesn't need much horsepower since
you're not forced to additionally compress the audio.
I suggest using a small 'embedded' type Linux-running system, like the

Please, PLEASE, P L E A S E tell me you're NOT trying to use those wideband
only radios on a narrowband Part 90 system!
They will NOT meet the emission mask for narrowband operation without turning
the total deviation below 2 kHz.
And the receivers will still be wideband.
Bad choice.

In the summer of 1964, when I was 13, my dad gave me a short wave receiver.
I'll never forget stumbling onto WWV. I often wondered who was the voice of
those announcements, and I was impressed as to the boldness and clarity of
the way the time was announced. I remember staying up at all hours
I remember growing up in Las Vegas in 1986. When it would rain and the
power would go out the old man would bust out the Sony shortwave and
put it on the diner table and we would sit in candle light while
eating and listening to WWV on 10MHz. Those were good times.
Out of curiosity (and part of a project I'm working on), what would a VHF
Mastr 2 Station draw as far as current is concerned, if the P/A is bypassed
(i.e. receiver, exciter, control shelf, IFAS and system boards)?
I have a need for a portable event repeater for an upcoming BSA event in
April.
I thought the voice of WWV was Lee Rogers, who is a very
active talk radio person out here on the west coast... currently
on KSFO 560 radio in the SF Bay Area.

I need help in identifying a VHF antenna. It is pretty old. I would say about
20+ years. It is built the way a DB-408 is, but the folded dipoles are the size
of a DB-224. think of it as a DB-208. It has the size mast of a DB-224, but
twice as many dipoles. The dipoles attach to the mast
