Hi Hans and Alan,
Thank you both for the information and the links Alan.
Have you any advice for me about question 1 of my last post:
If I run the ARDUINO UNO on battery power can I connect it to GND and Vin (as recommend by the arduino website) through your QRSS shield?
My contribution to the "BS170's in new kit PCB's - opinions please?"
post is why not supply a couple of 2N7000's in a seperate bag and those OM's who are not confident about which way round the BS 170's go can have the choice.

Hi Colin
As Alan said, there's a book see for the
details. People can still build and operate the QRSS Arduino shield without
the book. But the book does contain a lot of other interesting things and
would probably be useful for people who want to learn more. There's a huge
amount of information on Arduino around the internet too.

Hans has contributed three chapters, including one on QRSS and one on the
multimode transmitter shield, to the new ARRL book 'Hamradio for Arduino
and Picaxe'. It's well worth a look, it would probably answer your
questions.
If I've read it correctly, switches 1 and 2 give a value from 0 to 3 to
select modes None/QRSS/FSKCW/DFCW, similarly switches 3 and 4 give speeds
of 12WPM/QRSS3/QRSS6/QRSS10.
Loading Arduino sketches into ATtiny chips is covered here:
I think you will need an ATtiny44 or ATtiny84. The 8-pin ATtiny45/85 types
don't have enough pins for this application.
Hope this helps.

Hi Hans and all,
I have a couple of questions about the arduino shield.
1: If I run the UNO battery power can I connect it to GND and Vin (as
recommend by the arduino website) through your QRSS shield?
2: I have looked through the sketch to find out which DIP switch does
what but due to my limited knowledge I cant make head or tail of it, can
you tell me the various switch positions / modes? at the moment I have only
switch 1 in the on position this seems to be QRSS 3.
3: I think it must be possible to upload the sketch to a ATtiny chip or
similar (sorry lack of knowledge again) and breadboard the QRSS shield with
the chip, what sort of chip would I need ?
