Tentative group purchase of PCBs for F6BVA QO-100 3/13cm system
Our good friends in France are looking into the possibility of a group
purchase of PCBs for Michel's QO-100 system, which is a receive
converter for 3cm and transmit converter to 13cm from 2m/70cm/23cm,
avoiding the need for an SDR and LNB on receive if you prefer to use a
normal VHF radio on QO100.
I'm going to order a couple of boards for myself. Is anyone else
interested? I would be happy to facilitate the group purchase of
boards, cases and components as for the 3cm-UHF transverters.
Have a read of the project description. Note that it needs a local osc
(an SV1AFN 4351/controller is fine for this) and is designed to power a
PA using an MW7ic2725, for which a PCB will be produced as part of the
group purchase. I already have some MW7ic2725s for myself. They are
available on ebay and other dodgy sites. Richardson RFPD have some in
stock at $53 but then there is VAT and carriage and other malarkey.
Here is the description:

I can gauge the likely demand. Price is likely to be around £40 for the
PCBs. I haven't costed component sets, but there isn't anything unusual
in there. If there is any interest, I'll work out a more accurate cost
and ask for firm commitments to place an order for the PCBs via
Everything depends on there being sufficient demand for a PCB order,
this is *very* tentative at present.
