QRP QRCI Awards follow up
by Tim - N3TL 20 Jan '10

I've just looked through the awards section of the QRP ARCI Web site. Although FM is not specifically mentioned in the organization's definition of QRP, it is included on the awards application. The same is true for digital modes. The awards application is available on the site in PDF form here: http://www.qrparci.org/images/stories/GCR_Form.pdf I hope this is helpful. 73, Tim - N3TL

Re: TS-2000 70cm Tx problem with AO 7

Hi Mark, Yes it is a happy ending! Regards the 1296 board, it is one made by my ham colleague from a design by Bertrand Zauhar, VE2ZAZ. It places 8V on pin 3 of the PA which makes it more linear than the 6 or so volts that pin 3 of the PA was getting from its pad. I will send you more info directly. 73 Starr ZL3CU Mark L.

Re: Contact For Antenna Warehouse...

Hello Rupert. Unless you have paid 178.75 dollars, which is the price to ship to Europe by UPS, then I suspect you will not receive the arrow antenna. You need the lower paypal link, not the top one. Thanks David G0MRF In a message dated 18/01/2010 20:59:24 GMT Standard Time, rupert.hamblin(a)gmail.com writes: Hi All, Hope you could help.... I've now ordered an Arrow antenna (144 / 430) beam from Antenna Warehouse (www.antennawarehouse.com) . I've sent a PayPal order to them for $139. I need to get in touch with them to confirm receipt of the order and that they are happy to ship to the UK. I've tried the advertise phone number from their website...no reply and have left them a couple of messages..

>> ... my $50 membership thirty years ago is worth $1,000,000 in 2010 dollars ... All moot, of course. Your fifty bucks contributed years ago was exactly that - and nothing else - period. It was used back then - and any comparison to what it is worth today is valueless. "What have you done for AMSAT recently?" - is a much more appropriate discussion.
