[hpsdr] ATLAS TDR & VNA Test Results

[Eric Ellison]

Lyle

Thanks for the clarification. Although this is my personal opinion, I think
this board although it is a LOT of soldering, is suitable for self assembly,
for most folks. We can investigate an assembled unit after the first run.
For folks who absolutely can't assemble, perhaps there can be a 'buddy list'
of assemblers. The no lead is obviously of importance so we can ship to EU.

We now have 79 orders so the number is rising.

At this point I think we should go with 100 boards, and evaluate the second
run later. I'm open to suggestion. That should set the stage with enough of
us for the coming project boards. Also for folks getting in late or after
the first run sells out, the "No touch" method which Phil used is a great
way to do small 'group' buys. Price of the no-touch is only $51 a board in 3
quantity.

So far your quote is the most attractive in 100 quantity.

Does this house also do assembled boards? If so how does that work.
Obviously we will need that for SMT project boards.

I'm totally open to suggestion here:

Thanks
Eric - AA4SW

Since the boards will be hand assembled, the fiberglass need not be high 
temp. It is still RoHS compliant.

If the boards are to be used in automated assembly, then the fiberglass 
needs to be high temp or the boards are in danger of delamination.

The Chinese boards are RoHS compliant and suitable for hand assembly, 
not suitable for machine assembly.
