Hi
Yes. I will bring in the VNA, but I am travelling down from Nottingham Friday so I may be a bit late.
I am not sure if Colin has the crystals, but I have enough of them here to build one filter stage.
We could use the VNA to characterise the crystals Q and fc too, perhaps using the shunt method and a couple of 4:1 TLT's. I would hope a 200ohm test harness would work OK.
Colin is having trouble with the BFO output power I think, that needs to be fixed too. Sunil has not heard of any problems in that stage before.

The printed circuit boards and about 20% of the required components
arrived today from India.
I will bring one set in for discussion next Friday.
I would like to schedule the first build night to be Friday Sept 5th.
73Excellent Michael.I'm looking forward to getting started. I hope the PCB's look good.Should we take a close look at Colin's with a spectrum analyser / Sig gen /VNA etc to find any mods required before we start?73David
