Hello,
I am getting back to ham radio and homebrewing (qrp) after many years. I wanted to start by building the simple low power Picokeyer given in http://www.arrl.org/qst/2003/12/0312038.pdf I am currently in India and the MOSFET 2N7000 is not available here. The article says that I can use a 2N2222 with a current limiting resistor in the base or emitter. Can anyone help me with what resistor value to use? Also is there an older MOSFET that I can use instead of the 2N7000 since a MOSFET inherently uses very low current? Electronic parts are fairly inexpensive in India but only the older and more generic/popular ones are available. Also has anyone enhanced the original software for the picokeyer in open source/freely available form? I am also looking around to purchase a good paddle for qrp work (both qth and mobile) in the USA. I know from my previous stint in the hobby (qro) that Bencher paddles were just about the best, but they are also a little pricy - they have gone up 50% since the last time I checked. Is there a below $100 iambic paddle that is good for home and mobile use? Please post your replies. Thanks & Regards, Jay KC5TQS |
