Hi Ed, Nice thing to have access to. My thoughts would be for a delta loop ... easy to build, tune, match, but with a tower that tall, I think I would entertain building a bi-square. The wires from t
What is the QRP frequency on 160? Sounds fun. Would like to give it a try with my newly finished K3. 73, Mike WA5POK Way to go, Gary! I'll be on Top Band this week, starting this evening, lookin' for
That sounds fun ... I have a knight kit station I may try ... an Ocean Hopper and the Knight Broadcaster adjusted to slide up to 160, watt or so on 160 AM. That would be ridiculous. I use that Broadc
I have one of these units ... http://pw1.netcom.com/~t-rex/ ... A nifty device. I purchased the complete unit as a kit about 7 years ago for around $40 plus shipping. I have never seen him advertise
I perhaps have maybe a worst case scenario ... I live on a 60' by 90' lot in Houston. Fortunately I have some very nice tall pine trees that support my inverted L. It has one elevated radial in the s
Hi Jim, I just use a simple SPST open frame relay to ground the vertical section of the antenna and no I do not use QSK ... yet ... (need to add it to the old amp) The vertical section is about 60 an
DANG! I haven't seen one of those in a couple of hundred years! You didn't comment whether or not you were you on the air at the time or how far from the ground the change in diameter is. However, I
Looking at the front cover brings to mind this web page. Yep, their ferrite rods are very expensive! http://www.stormwise.com/ 73, Mike WA5POK Speaking of ferrite RX loops... I picked up the July 201
I will also echo the comments on the Antec power supplies. Used one as a replacement a couple of years ago and the computer noise is gone. Mike WA5POK Ditto on the Antec, Ive been using them on both
The feed point of my inverted L was blown apart and the copper inside the insulation (both the "L" and horizontal elevated radial) was reduced to a black, brittle mess from a lightning strike and an
Google VLF receivers and the circuitry to build the Earth songs rx is very simple. I have done this with my students a few year back. The only problem is finding a 60 Hz free environment to use them.
Will the K9AY loop be workable installed among trees? Yes. I had one suspended from a tree branch for many years on my 90' X 60' lot that was heavily populated with pine and sweet gum trees. 73, Mike
Sorry Jim, That one is reserved for us cavers ;) I suppose that "We do it in the dark" wouldn't go over very well, right? 73, Jim N7US --Original Message-- "offensive?" How about "Tuesday?" Is THAT o
Gotta debate that one Jim. Hi!Hi! ... Topband signatures ... anything with "Beverage" or type of ... is FB with me. Mike, sorry buddy..... It is reserved for us (now retired) military folk....... The

I think I would hang a delta loop off of that tower. It would be very slightly squashed. You would not have to worry about matching the tower or installing a radial system. Through in about a db of g
I would hang a delta loop off of that tower very easy to tune and match with a 1/4 wave length 75 ohm coax. You don't have to worry about complex matching systems or ground. BUT it is noisy on receiv
I put a delta loop fed at a corner with the apex at only 100' (slightly squashed). We compared it to an inverted V that was on another tower about 200' away that was also 100'. A/B indicated the delt
Some one is having too much fun! I may have to try that! Great Job! 73, Mike WA5POK Qrp on 160 is fun: CQ WW CW this year: SOSB/160 QRP Call QSOs Zones Countries Op Time Score Club
Hi Art,Yes, I have done that and am doing that. I use tall trees as supports and the 160 inverted L goes up one side of the tree then bent over horizontally to another tree over yonder. From the same
