I have only heard the fishnet beacons in the upper half of the band. They would probably disappear quickly if we moved cw to the high end and phone to the low end. 73 Art _________________ Topband Re
The QTH here is S.W. Michigan I have 3 BOGs working pretty well. One for NE, one for SW, and one on South America. Do I need one pointed north? Do signals go over the pole on 160? Art _______________
Luis has a nice webpage. I have read several times about the pattern distortion if the coax shields are grounded at the transformers. (on the RBOG) If the coax shields are common in the shack, i.e. c
I participated for a couple hours. QRN was very high in S.W. Michigan. I found some relief by phasing a BOG with my OCF antenna while transmitting on the inv. L. KV4FZ and HC1PF were copyable, but th
Remote stations should be operated in the assisted class during contests.. As far as DXCC, how about an endorsement for all stations who earned it using only their local station? My $0.02 Art NK8X __
I was tuning around tonight about an hour before local sunset, and heard a fishnet beacon on 1960KHz. I think it was PFB1 or something like that. I only heard it twice before it faded. I happened to
I am not sure what it would accomplish, but we could put the loggings on the DX cluster. Art _________________ Topband Reflector Archives - http://www.contesting.com/_topband
I was a bit surprised by the apparent grey line propagation. Bruce's observation of the beacon being located near the Grand Banks, would be consistent with the timing. The loop had been oriented towa
Mike, Are you referring to a specific modulation mode? How about adjacent channel interference issues? I like your question. Art On Tue, Aug 4, 2015 at 7:39 PM, Mike Waters <mikewate@gmail.com> wrote
If the noise level is too high, perhaps you could use a separate receive antenna. A pennant, flag, or coaxial loop, might help null noise from certain directions. Art NK8X _________________ Topband R
Has anyone tried merely dropping a lightweight wire over the side of the building as a receive-only antenna? That might get it away from the plane of interference from the equipment at the top. _____
Is there a reason to favor relays over taking a pin diode to ground to short the input during tx? Art NK8X _________________ Topband Reflector Archives - http://www.contesting.com/_topband
This question is about bi-directional beverages, or more specifically BOG's using a reflection transformer. How does the loss on the forward and reverse direction compare to an omnidirectional refere
In the last couple days I have copied both VK3IO and E6GG on 160 cw at sunrise. They were weak here, but not bad for a 200ft BOG in a residential neighborhood. The KD9SV pHEMT FET preamp is a nice ad
I have another preamp that uses an old MRF-904. Have you characterized that transistor at 1.8MHz? Is it worth replacing with a 2N5109? Art _________________ Topband Reflector Archives - http://www.co
I was thinking about phased BOGs. Would the horizontal spacing and/or stagger between them, be reduced due to the Vp change from ground proximity? Art NK8X _________________ Topband Reflector Archive
I would start by confirming the matching transformer works properly on 1.8MHz. Art _________________ Topband Reflector Archives - http://www.contesting.com/_topband
Luis's BOG page is very informative. Last night's contest was the first time I have used directional receiving antennas (in this case BOGs) during a contest on TB. Art NK8X _________________ Topband
