Hi,

Bryan makes some very valid points:

If you agree or not he WAS there.


Someone needs to tell Bryan that all the problems he describes are either non-existent or have been resolved (read this thread).  Also, HamCation or PacificCon can never be viable hamfests because they do not have the DARA volunteers to pull it off....

Yes, what a pleasant surprise this afternoon!

I worked George just before 2pm local on 20 m long path. He didn't seem to be hearing terribly well, but he stuck with me till we were both sure of our QSO. Good signal here, about S5-6.

I heard a rumor that the IC-7610 has a very tiny, high definition pinhole video camera built-in to the front somewhere for real time wireless ESSB teleconferencing over HF.  Supposedly, digital compression in the radio limits bandwidth to just 200 KHz, with the picture displayed on the 7610 touchscreen..........

.......and via the new version of HRD which will, at the click of a mouse, print off the picture superimposed on your QSL card.

Not only that, Icom have thought on the other "musts" - an optional plug in external camera that will allow for the obligatory shack/rig picture featuring sheeple-ham man's newest latest big TV screen Icom model......again, all auto-uploaded onto your QRZ page via HRD.

New stocks of XXXXL size Icom tee-shirts available for all the puffed up chests.   Grin

I had never come across the PA0RDT active antenna before. His own clear explanation, with measurements, is http://dl1dbc.net/SAQ/Mwhip/Article_pa0rdt-Mini-Whip_English.pdf. It seems convincing, although puzzling as it seems to say the opposite of what the textbooks say about local noise. Then I read http://owenduffy.net/antenna/PA0RDT-MiniWhip/, which casts serious doubt on the claimed operation principle. My tentative conclusion is that it works, but perhaps not in the way the inventor believes. This is not unusual for a compact antenna!
