hi michael,
if you decide you want to have 48 downconverters, and then use a low rate
48 input ADC board, then
a) you could implement downconverters with connectorized (eg:minicircuits)
mixers, filters, amplifiers
about $100 per channel
b) you could make your own PCB, or perhaps use

if vinand,
if you want to digitize 48 signals with 250 KHz bandwidth, you might want
to consider
purchasing a 48 input PCIe ADC board and doing the signal processing in a
computer (in software).
(not use FPGA boards).
but then you'd have to mix the deuterium line to baseband, so you'd need 48

Are you envisaging an array, like the D1 telescope at Haystack?

Depending on your requirements, you could look at the tpm module that wqs
designed for the ska low frquency aperture array.

Hi all,
We are looking at building a telescope in Mauritius which is called the
Mauritius Deuterium Telescope, MDT for short. As the name suggests it is a
Deuterium focused experiment. We have planned for a pathfinder station to
be built for the end of this year and had in mind the SNAP boards
Hi Jake,
That's interesting, good catch -- if you want to raise a pull request
supporting VLANs on the MB feel free to do so.

Hi all,
Thanks for all the help.
After much debugging, I found that my NIC for some reason is adding the
802.1Q VLAN tag to all outgoing packets. Since the lwip module doesn't
support VLAN by default it was dropping all incoming packets.
I recompiled the microblaze software but I changed
