Thanks to a great response, the first batch of Red Pitaya 14:1 impedance
transformers sold out in less than 24 hours.  USPS reports that all
domestic shipments should be delivered by the end of today.

I've ordered another batch of transformers from the company, and they
should arrive soon.  I'll begin accepting new orders on my web site
<http://www.kkn.net/~n6tv/XFMR> as soon as they arrive.

Regarding shipments direct from Europe, the CEO of the Red Pitaya company
just wrote to me:

"... we are rebuilding the whole web page due to some issues we have and it
will take some time to fix everything and launch a new page. Till than we
will not be selling the transformer boards."

That being the case, I will be happy to ship to any country served by the
USPS.  Standard Flat Rate Priority shipping is expensive (USD $32.25), but
it seems I can ship via slower "First Class International Package" rates of
about USD $13.00 (varies by country).  Unfortunately, using PayPal, I have
to configure shipping prices individually for each country.

If you want me to ship overseas, and are *not* in one of the following
countries, please send me an email (off list), and I will add a shipping
option for your country:

United Kingdom
