Hi everybody,

Maby this isn't the good place to ask, but for my work and a project we're
working on, I'm looking for RF receivers (say up to 60MHz) which can be
remotely controlled through local network and TCP/IP. The goal being an
operator to be able to tune the receivers from his workstation which can be
located somewhere else in the building.

If anybody knows of such products, I'd be happy to get some pointers, links,
informations, etc...

Thanks in advance.

Eric

Take your pick there are anumber of the mout there e.g. Ham Radio
Deluxe has a remote server function that would allow this type of
operation. ALl you need is a computer with WinXP on it a supported radio
of your choice and a little config work.

Depends on what you need in a receiver. SSB? Ppm stability? Variable
bandwidth? Or would a scanner that covers the frequency and receives
AM and FM be enough?

But any receiver that can be controlled with software can be
controlled over your LAN - just install UltraVNC
http://ultravnc.sourceforge.net/ on the computer the receiver is
connected to, and the UltraVNC client on the computer you want to use
for control and you can control it with the software you normally use
for controlling that receiver locally. (You'll have to use something
else - I use Winamp with the Oddcast plugin and Icecast - to remote
the audio.)

Hi Al,

Actually, scanners that covers AM and FM would be enough. No need of too
sophisticated devices for our experimentations.

When I saw that most receivers (if not all) allow interconnect through a
serial port only, I though about the vnc solution. However, as we plan a
cluster of receivers, I'd have prefered to find receivers with an on board
network port...

We don't need audio since it'll follow another path in our system. It's just
for controlling the receivers.

In the mean time, I stumbled across the WinRadio receiver PC boards, what
could be the solution. We could put several boards into a clean rack mounted
computer, and WinRadio to provide the remote server software. Moreover, I've
found some sourceforge projects which provides drivers and libraries (among
other), this would allow the host computer to run on unix, thus much
customization...

Many thanks for your input, Eric

Thanks Panzer,
Wow, this HRD stuff really looks neat!

I think this would be a nice solution if we turn our choice to "external"
receivers. Though, I'm now thinking about the WinRadio PC boards solution (see
my follow-up to Al). A 19" computer full of WinRadio boards could be well
integrated to our system...

Now I need to check if the mini-jack on the rear of WinRadio boards really is
for audio output since we need independant analog output for each receiver
(e.g. not from the computer's sound board)

best regards, Eric

Eric,

I saw all the posts and all had great suggestions. If your shop
is linux based check out gnuradio, just do a google search. I'd
like to know how you are going to handle audio output to the individuals
tuning the rx's. Its something I'm interested in too. Also, are you
considering the ability for one person to tune multiple rx's and
then feed multiple streams of audio back? If so and you've got
an idea for a solution I'd really appreciate hearing that.

Let me know.
TIA

Winamp/Oddcast/Icecast will do that nicely and free. One stream per
receiver (or two - one on each stereo channel).

thanks .. i was figuring you were going to go down that route
but i wasnt sure. Care to share more of the setup details?
