Topband: small rx loops and ferrite
Since the topic of ferrite seems to be at the top of the lists focus I'd like to ask about what ferrite mix to use at the feed of a small rx loop I have built this is NOT a shielded loop with the break in the shield half way around the loop I made the loop out of the 2 turns of 5/8 inch hardline I had available the circumference is about 12' I am using only the shield as a continuous 2 turn loop for the feedline I just attached a 50 ohm coax with the coax center to one end of the hardline shield and the coax shield to the other end of the hardline shield it worked fine for what I wanted in the sense that it allowed me to null some thunderstorm crash noise during the Summer Stew allowing me to diversity receive with my outside vertical on my K3 (it even works on 80m and 40m, so the toroid needs to work 160m-40m) however the pattern is not symmetrical (I think this is due to the unbalanced 15' of direct coax feedline?) so I think my next step would be to use a toroid as a balun with each end of the hardline loop attached by a couple of turns on the toroid and maybe twice that many turns on the other side of the toroid going to my 15 feet of 50 ohm coax to the rig I might later get around to building a preamp for it but for now all I want to do is add the toroid in the hopes that it will maybe make the pattern more symmetrical if I understand this correctly I am wanting to use a broadband coupling FTxx-xx ferrite core rather than a narrow high Q like I would get with powdered iron Txx-xx core I have an FT240-31, as well as FT37-61, and a FT50-61 on hand in my part bin. they were left overs from an order from Tony at http://partsandkits.com/toroids.php I used all the hard line I had on hand so different lengths, configurations etc etc etc is not my question, for now... I just want to know what mix toroid I need to use between this loop and the coax feed to it I was planing on 4 turns on the primary and 16 turns on the secondary my reasoning being that might also give me a little signal increase as well? perhaps later I might get into the matching aspects of this experiment but I had plenty of signal strength using the coax directly with the loop setting in my 'other room' of my ground floor apartment I just thought it would be nice to have a symmetrical pattern rather than the odd ball one I have now -- GB 73 K5OAI Sam Morgan ___ UR RST IS ... ... ..9 QSB QSB - hw?

Topband: new 160m propagation prediction software
the following is an excerpt from the ARLP013 Propagation de K7RA From Tad Cook, K7RA Seattle, WA March 30, 2012 quote Q-up Now has a fascinating new set of real-time propagation tools at http://www.q-upnow.com/, developed by a team associated with the Utah State University Space Weather Center (http://spaceweather.usu.edu/) in Logan, Utah. They use a real-time model of the ionosphere called GAIM (Global Assimilation of Ionospheric Measurements) which is updated every 15 minutes with 10,000 global TEC (Total Electron Content) measurements to simulate the F layers. Then they use the ABBYNormal Model (see http://gcmd.nasa.gov/records/abbyNormal.html) to model the D and E layers, and the two models are combined to give a complete representation of the global ionosphere. On the first page you will see NVIS maps for Near Vertical Incidence Skywave propagation. These are not quite ready yet, and currently the maps shown are several days old. Most interesting is the HF Availability (http://www.q-upnow.com/hf-availability) area in which you can model real-time propagation for the frequency of your choice between any two points and beyond out to the antipodes. You can use latitude/longitude coordinates, but I found it easiest to just copy grid square data from callsign servers such as http://www.qrz.com. This tool also works on 160 meters, which the propagation prediction programs that many of us use do not. Of course the major difference with this tool is that it tells you what the propagation should be over any path right now, but they are planning on offering a predictive tool. /quote -- GB 73 K5OAI Sam Morgan ___ UR RST IS ... ... ..9 QSB QSB - hw?

Re: Topband: cq 160
I run into that problem they just keep calling without space between cq's. often myself. My guesses are, they are either not even listening, just trying to keep their claim to that frequency by the never ending cq's. I say it that way, because they don't seem to even leave enough space between their never ending, automated cq's, to even hear a station if they was one attempting to answer. Or maybe they have some really good directional antennas and are listening towards some part of the globe I'm not on, hi hi. Then again it could be their receive capabilities are being limited by QRN/QRM that I can't hear. But it is pretty upsetting when you have waited until the big gun stations are in bed, so you will not have to compete with them in the pileups, and can hear the station calling cq so well, and yet it seems your answers to their endless calls are being ignored.

Now for the added treat, my 5w qrp signal, will be transmitted from a 7' tall Hi-Q 6/160 antenna, mounted @ 20' with 16 radials, ea 13' long. At the claimed 6% efficiency, that means my ERP should be about 300mw. Operating times will be from SS -1hr to SR +2-3 hrs or about 2300 UTC Sat - 1600 UTC Sun a couple of hrs sleep may be optional depends if the contacts go dead after 3-4am local CDT 8-9 UTC Good luck, hope to be in your logs by contests end on Sunday P.S. how active the results of this Pre Stew Perry are, will help decide if I will operate QRP 5w x %6=300mw or 100w x 6%=6w in the Stew Perry it's great to give out the QRP/s times 4 contact points, but if the number of QSO's is so low, as to be boring... (pun intended, hi hi) I may have to opt for running as a big gun QRO 100w x 6%=6w tx signal in the November Stew Perry and only be worth 2 contact points. your log entry will help decide, TIA ___ UR RST IS ... ... ..9 QSB QSB - hw?

Re: Topband: Topband report - QRN extreme
noise, you want to talk noise.? http://pages.suddenlink.net/k5oai/2011-rfi-noise.html GB 73 K5OAI Sam Morgan On 1/6/2011 11:57 PM, Mark Lunday wrote: Wow, the QRN is deafening. I can hear F5IN at his sunrise 599 to 10 over, but the static is jumping to 20 over on my inverted L. Never heard anything this extreme in winter. It's bad on 40 and 80 also. Obviously due to the geo storm in progress. I will be putting up my very first beverage this weekend. Hoping that it is less susceptible to this type of QRN.
