I am curious what beam heading (for lack of a better term), you received them at this morning. I was unable to copy them on my SW BOG or on the Inv L, but had pretty decent copy on my OCF antenna at

I ran into a rather odd source of RFI, possibly common mode. I had 2 transformer type Astron power supplies in the ham shack. One was a 15 amp desktop type, the other a 35 amp rackmount unit. My obse

I am curious about terminating RG-6 cable connections in the ham shack. I have been using several types of adapters, i.e. F female to BNC male, F female to UHF male, or F female to RCA. I have not be

At the risk of sounding redundant, be very careful when messing around with the bonding/grounding of the electrical panel. Over the years I have seen significant current on these circuits due to a wi

If I placed a NW favoring BOG adjacent to my SE favoring BOG, would there be significant harmful interaction? Obviously the transmission lines would be on opposite sides, but the ground connections w

Tom's comments sparked a question. (No pun intended). Does the SNR of the targeted noise source vs. other signals on the sense antenna, matter in this application? Art NK8X _________________ Topband

It depends on how good your ground plane is. W8JI has an interesting page about FCP vs radials. http://www.w8ji.com/fcp_folded_counterpoise_system.htm Perhaps you could measure the current on your ex

I'm a relative newbie on 160 (about 5 years) but it seems most DX hangs out on CW between 1820 and 1835. The situation may be different during contests, due to channel availability. 73 de NK8X ______

Has anyone tried a v-beam configuration on the ground, similar to a bog? Obviously, it would be longer. The intent would be to increase RDF. Or would that be a waste of time? Art NK8X _______________
