Roger I am curious, why Wednesday night ( when many have to get up and go to work the next morning?) instead of Friday or Saturday? Was on.. on and off the only station on CW early in the evening was
I think the spacing is a bit wide try something more on the order of 250-270' ( goes through the middle of the house right ....8^) Dave NR1DX On 10/18/2020 11:20 AM, Kenny Silverman wrote: My new ho
Bill Last night ON 160 I worked 32 European and SA stations with the reported SFI of 88. earlier in the week with a similar SFI number I heard nothing from EU on 160. Conclusion : At these levels SF
Bill Arcing is probably not an issue at least for the 1st couple of years. I guess at some point 10 years down the road and your bargain wire is likely not UV resistant rated (?) Over time it will w
Among other things they will and can arc if very close or even intermittently touching. if they are not bonded the currents and voltages on each wire may be different enough to arc then you get inter

Tom I'm using a 470 foot E/W Beverage here in Florida on receive and a 60' high "T" with four 90' elevated radials for transmit (TS890/KPA1500) . The CW operation the first night was quite a QSB ro
Conditions certainly didn't favor 160 over the weekend CQWW contest here in Florida at least. Looking back in 2019 I worked 50 countries on 160 during CQWW, this year it was only 17, only 3 Europeans
Ron Count me in , I agree no same country contacts, PERIOD AND.... you wouldn't loose any zones ..zones 3, 4 and 5 are covered in Canada as well! Dave NR1DX However, checking the stats, almost 1/3 of
Wes You got that right,you gotta walk a mile in the other guys shoes!! When I lived in New Hampshire working EU on 160 was a walk in the park compared to the kind of propagation we get down here in F
Ed What receiver do you have now? You may not need a preamp at all? Have you tried the BOG without a preamp yet? Dave Any good? If not this one, which preamp would you recommend for a BOG antenna? __
Especially if you have elevated radials you will need a choke otherwise the coax and your shack will become part of the ground plane. . In my case I have a choke ( for common mode currents) and UNUN
Jim et all I agree with what you say on all points when it comes to radials on the ground and salt water affects. However I have always wondered about elevated radials . The NEC ( both 2 and 4) model
OR The propagation mode on 160 is not what we have popularly come to "Accept". There is a growing body of evidence that particularly at gray line that signals often arrive at a higher angles. This is
Here in Florida in the evenings we get a fairly consistent opening to Europe it begins about 1 hour BEFORE local Sunset (2215Z) , Peaks about 1/2 hour before Sunset and then all but dies out on most
Not a simple , on size fits all answer What happens depends on the frequency you are talking about ( I assume 1.825 but if it is a multi band vertical ..then???) and how much above the ground pl
Kenny My personal experience with radials on the ground is that with a fair number (16 or more) that I end up with little if any common mode currents on the coax . Smaller (numbers of) ground mounted
Jim/ K9YC I am with you 100% on your comments below my 80/ 160 verticals all run "10 lbs of ferrite" at the feed points but that is because I run elevated non resonant radials these days. 5lbs of fer
True indeed Charlie It was such an observation by accident that clued me into the fact that I needed a choke on a system with elevated radials the first time :) Dave NR1DX On 1/1/2021 2:10 PM, n0tt1@
Mike & Bill Thank you!!! I sometimes think there is too much emphasis on NEC modelling and never enough real world verification with actual field measurements {I have hijacked the original thread and
