The Keyspan adaptors are well supported in most modern OSes. In general any adaptor that uses the Prolific USB to serial chipset (i.e. Prolific Technology's PL-2303H/X/HX) will use the drivers in Mac

Look at the link I posted to the ten tec wiki on filters and my comment about the stock numbers. You can use the stock numbers to determine the filter model. There will often be two numbers on the fi

The Paragon (I and II) used a "normal" 4 octave PLL synthesized LO (with all the usual problems of increased phased noise) to get GC coverage. The Omni V (and VI) on the other hand used a narrow rang

See my post on the difference between the two. IMHO (and I think most of the nets HO too) the Omni V Better phase noise. Better crystal filtering close to the fist mixer (the advantage of a low IF co

The problem with getting to First Class is you need time on the air using CW. And that doesn't happen any more what with GMDSS. <http://groups.yahoo.com/group/Ham-Radio-History/message/10498? threade

The drivers for the Prolific USB to serial chip set are built into most OSes these day (Mac OS X, Linux, FreeBSD and Windows). So for a NoName device check to see if it is Prolific based. There are a

My favorite X ray generator had a similar (though perhaps lower current) spec. "Contact with potentials in this equipment WILL cause death." I was most impressed with the certainty of the prediction!

Except it sucks if you already have a network in place that has a zero in the second or third octets. It's a legal address (though it seems that the O7 assumes you have a "Class C" network, an odd as

I've seen similar criticism in 1990s Technical Topics columns in RadCom. The 1N4007 does well on insertion loss, 2nd order IP and 3rd order IP but fails on isolation (worst case 35dB at 10m rather th

Actually I was thinking in terms of full reverse V across each diode. Just have to DC isolate each diode and provide the bias/reverse V separately for each one. No more complex that the shunt option
