Ham radio pulled into territorial dispute. China is using amateur radio to claim sovereignty of Scarborough Reef.

: Wednesday , May 30, 2012 CQ WW WPX CW 2012 Last weekend was the weekend of the CW version of the CQ WW WPX contest . I am not a serious competitor as it isn't really practical with attic antennas but I like to come on for the big contests to give away a few points and see what I can work . Perhaps they should create a special category for stations with indoor antennas . I only managed about an hour on Saturday and a couple of hours on Sunday as I easily get tired out . But I thought it would be an opportunity to put the KX3 through its paces . Although I don't plan on sending in any more than a check log , when operating QRP I like to adhere to QRP power levels , so I limited the KX3's output to 5 . watts Other bloggers have written that conditions were good for the contest , but I

Several things will interrupt any objectives in the next month or so , but my next objectives : are a Improve the sensitivity of my optical transceiver . RX b Build a new transverter for the 472-479kHz band due to be released Jan 1st 2013 in the UK we expect The first will allow me to use the dual-optics 481THz transceiver over longer paths . I hope to make some contacts

Perhaps the most popular type of transistor is the bipolar junction transistor (BJT). Bipolar junction transistors are three-terminal devices, called the emitter, base, and collector. In an NPN transistor, the emitter and collector are N-type material and the base is P-type material. In a PNP transistor, the emitter and collector are P-type, while the base [...]

I don't need A5A for a new one (thanks to A52PP last year) but I've been looking looking for these guys on 20 Meters since the start of their DXPedition and haven't heard them there at all. Not a peep.
Adsense would surely produce more revenue but I don't trust Ghougle AT ALL so I'll just stick with my eBay Publisher Network Ham Radio related ads for now. Think I'll go buy a couple new coax connectors :)
