Bob.. I think the wave equation comes from Maxwell's curl E and curl H equations.. a minor slip, but elegant explanation of D. Also, your Top Gun book is spledid! Cheers Joe VO1NA

I haven't heard a peep out of him since I started listening a couple of days ago. Hope he can continue to try around 0730Z... after that the sun starts to rise here. I did hear one east coast station

I built a small wheatstone bridge with a composition vairable resistor. When the nul was reached, the resistor was put across a dmm via a DPDT switch. I used this to prepare a plot of R vs Number of

Hi Bill. I didn't hear anthing from 5R/TI9/PW0 because of the SSB below 1843 which included several VE/VA/VY stations calling CQ. I believe RAC (our national organisation) has a procedure in place to

My only concern with this is that it would adversely affect any efforts to establish a world-wide CW segment from 1800-1840. Most countries acknowledge this segment in their band plans. 73 VO1NA -- F

There is a local OHT radar about 30 miles to the south of my QTH. The buzz is extremely loud and irritating... and it will be back again. Hams in Newfoundland were NOT informed. It seems there's noth

I've been toying with the idea of putting a beacon on 160. My location on the eastern tip of NA is ideal for an indicator of transatlantic openings. To reduce the potential for QRM I think it would b

Yes, I've heard it too. It appears to be centred on 1806 and although I can take most of it out with the .5 and .25 kc filters, it is still troublesome. XZ1N was 569 again around 2350Z here. Joe VO1N
