Since the subject of "un-intentional radiators " has come up , I had one appear about a week ago . 5 very clean very stable -80dBm carriers 4 khz apart starting at 1815.957, 1819.957, 1823.957, 1827.
BTW Kits and Parts has good assortment of cores at reasonable prices http://www.kitsandparts.com/toroids.php 73 Hank K7HP -- Original Message -- _________________ Topband Reflector Archives - http://
Is there any point in trying a 160 foot or so BOG down an alley if there are powerlines and phone lines and cable TV 15 to 30 feet above ??? (Along with Centurylink VDSL2 carriers across band 2 to 3
I bought a box of 50 Belden Snap N Seal - the box says RG-6/6QS which I assumed meant it was ok for both but have never used it on anything but regular RG6 - I have the Belden Tool which I bought at
My two cents is - at least with FT8 so far 99.99 percent of the folks stay in the 2 - 3 khz segment . I am amazed I see virtually nothing about the proliferation of 3 khz wideband digital two way has
I always check 160 on my GMT Christmas Eve - In 2013 I worked 8 EU in about 30 min - from here on city lot in Phoenix, AZ . Just an 80M inv vee at 39 feet !!! So far no repeat. Guess Santa Sleigh not
Guys - there is already a system with a "flood of signals " authorized for ADSL and VDSL . They go thru 160 , 80 , 40 every 4 khz (specs say every 4.375 khz) but here in NE Phoenix they are precisely
I was going to stay out of this low inv vee antenna - probably should - but here goes. The short remark is I believe N6RK comments are true - its a top loaded vertical with a little inv vee thrown in
My first priority would be a RF quiet location and best prospects of it staying that way - Been in same house over 40 years - last ten years in particular ambient noise and incredible numbers of ever
Seems to me the people who should be screaming bloody murder are all the millions with watches and clocks that correct using the 60 kHz transmissions . Most of those millions probably know absolutely
FWIW -- I don't know about polarization - but this evening/early morning 0700 to 0800 here in Phoenix on a city lot buried in noise - I was hearing CT9/DJ2YA , H7/RM0F, C6AGU LOUD and was hearing sev
Just for grins - did a EZNEC free space - perfect ground - with 80 m vertical of #12 wire resonant at 3.55 mhz then put another #12 quarter wave resonant wire at right angles to the top thru 1 megohm
Now that I think about it a bit -- I wonder if you put up a small vertical off to the side toward the W3LPL RBN and fed some power into it as a reference signal then fed the tower with that little ve
Arrgghhh - maybe you have a deal with W3LPL -to give you his RX output - this wont work otherwise because of the delay for next RBN output - - but maybe you have someone around to give you a CW signa
Toggling switch also keeps people from going down the street seeing which doors they can open because its using a canned security code. We had one yesterday on a bicycle ride down the street. -nope w
Modeling of Milt N5IA 160 8 circle with his 80M 4SQ out side showed same thing - need to leave the 80 M elements open Hank K7HP m 4 saw exercise! _________________ Searchable Archives: http://www.con
FWIW -- I was looking at All Electronics website last night - looks like they have unearthed a bunch of WW2 TX micas -at what looks like reasonable prices Reduced Price 0.0004 UF, 5000 VOLTS MICA CAP
Another drifting source that slowly drifts across 80 meters and repeats turns out to be a "Solar Boy" one of the cheap garden ":Little Boy" with LED lights at night . For several days I thought it wa
Where is the place to see active 1610 stations - I used to hear the one for Sky Harbour A/P here in Phoenix - but no more -hope not just further evidence of incredible increase in noise in last 5 yea
