Re: Topband: VE1PZ
VE1PZ is a good friend of mine based out of Pictou, NS. ( I say based as at times he's had different houses and cottages in the region) He's never operated remote that I know of. Doug is a stand up guy and the word cheating is not in his vocabulary. I don't know his current stn setup, but suffice to say he knows Topband and likely is running a shunt fed tower or tall inverted L within a snowballs throw of the Northumberland straight. He's been on TopBand longer than I have (I got on around 1991 I think)... He (and I) hold the CQ160 M/S record (from his stn, with his call) and we, along with K7BV did CY9AA in 1997..where we made many Topband contacts..actually Doug made most of the Q;'s on Topband. http://www.uksmg.org/content/cy9photo.htm He's also an accomplished 6m op. If you don't know the call, I respectfully submit you just have not been paying attention. May I suggest before accusing this fella of some wrongdoing, you at least have SOME facts in hand? I'm sorry he (apparently) beat you in the pileups, but tough noogies for you ! Mike VE9AA Mike, Coreen & Corey Keswick Ridge, NB _ Topband Reflector Archives - http://www.contesting.com/_topband

Re: Topband: 9Q0HQ
The flag, EWW, K9AY and others loaded loop antenna are indeed two non-resonant phased vertical phased 180 degree resulting in a cardioid pattern that provide directivity and a good F/B. When you have another resonant element nearby the interaction changes the pattern, depending on the new resonant element acting as a director or a reflector the new pattern can be very distorted, and it could be any shape. Any loaded loop RX antenna near a resonant antenna has useless pattern and most of the time the signal to noise ratio is the same on the flag or on the resonant antenna. Detuning fiscally the resonant antenna is a must to improve signal to noise ratio. No free beef here. Another factor is the feed line of the flag, Coax does not work well because the common mode current outside the braid works like a vertical if no choked properly, twisted pair unshielded is the only way to avoid use of chokes. Horizontal flag does help but needs to be high above ground.

Topband: BROKEN DIPOLE
Hi Alfeo >> On top band we use a inverted L and on 80m a vertical with a parasite reflector.We have the feeling that ous signal is strong enough << I appreciate your effort on 160m, actually I am following you on you ban DX expeditions for few years and one thing I noticed is the lack of signal on 160m. Let me do a constructive comment about this kind of TX antenna. I don't know where this thing started. A low inverted V is a very poor TX antenna, but the current is at the maximum high above ground, now if one leg get broken and the fed line is heavy and also drops to the ground, you got a broken antenna and someone called inverted "L". IT IS A BROQUEN DIPOLE, IT DOES NOT WORK. To be an inverted "L' it needs a ground plane or a connection with the ground, Elevated radial starts with 4 resonant radials , 3 does not work, 2 does not work and 1 does not work at all. I've seen several DX expedition wasting a lot of time on TOP BAND calling a broken dipole as inverted L. It needs a ground plane. As an example, I remember two DX expedition on the same area South Africa that had very poor performance on 160m using this broken dipole, and at the same time DJ7RJ was on 160m from a nearby country and his signal was always good and easy to copy. Maybe Willi have the secret TX antenna that's work. 73.s JC N4IS _ Topband Reflector Archives - http://www.contesting.com/_topband
Re: Topband: 9Q0HQ
Try an insulated wire, 66 meters long, on the ground (BOG antenna) If a transformer is not available, connect directly to the receiver auxillary antenna port. Signals will be weak, but noise should be much weaker. Hope this works, It is easy to try. 73 Bruce-K1FZ www.qsl.net/k1fz/bogantennanotes/index.html .I am afraid that a beverage would not help us due to the soil propriety.

Re: Topband: DSP and Latency
It would be rare for an internet connection to be a single hop. I forget the command (something like tracert) but you can see the nodes where the connection goes. The number of hops is usually minimized as much as possible. The NYC to KP4 connection is a minimum of 3 hops most likely: NYC PC to internet provider (NYC), internet provider (NYC) to internet provider (KP4), and internet provider (KP4) to KP4 PC. If I recall the return route may be different. In your TV example, just the difference between HD and non-HD will show latency even if the TV's are connected the same way otherwise. Perhaps the delay is due to converting HD to non-HD at the source although it seems like HD usually trails non-HD. 73, Larry W6NWS -Original Message- From: D Rodman MD Sent: Thursday, March 19, 2015 6:41 AM To: topband@contesting.com Subject: Re: Topband: DSP and Latency Everything takes time.
