Cool
I planned to assemble one on a piece of perf board, but this would be cleaner.

The reason that most of these shops in China that sell on eBay are able to offer free shipping is that the Chinese?
Government subsidizes shipping to help promote eCommerce.?

Chris,

Should be fine. Duty is only charged on items if total is over ?15 inc postage after currency conversion.

I agree.

I suppose most of us can take a risk and afford normal letter 1,5$ ;-)

The shipping is free for domestic and international. There were some initial problems with PayPal, but I believe all is resolved.

Thanks for making this so easy and inexpensive.

there seams to be a error on the parts list.

C1-C2 and C3 are? .1
C4-C5-and C6 are .01

parts list has them all as .1


 

FYI,
I designed that circuit and C4,5 and 6 are supposed to be .01 RF Bypass capacitors. ?.1's may be too much capacitance for the circuit to work properly and I actually left them out in the original design. ?I didn't have any RF problems but I have my uBITX in a well shielded case made from double sided PC material with all sides connected together and grounded. ?

BTW qrpguys negotiated with me for the rights to market that design and did a really nice job on the PC boards.

very good.
I ordered my board and your saying I should use .01 for C4-C5- and C6, correct ?

That's what I said. .01 uF. ?The input caps (C1, C2 and C3)?should be .1 uF.
