Re: Hf antenna
What band or bands do you intend on using?
What coax or open ladder line feed do you intend on using? Are you going to use an Transmitter tuner. Also known as an antenna tuner, but incorrectly designated. The formula for a 1/2 wave dipole is 468 divided by the frequency in Mhz.. Leave a little extra to loop through insulators and pruning-tuning. So if you're interested in 40 meters CW,,, that frequency band is 7.000 to 7.100 mhz.. You would want to center in the band.. so use 7.050 mhz 468 / 7.050 equals.. 66.38 feet.. each leg would be 33.19 feet.. Again add some for looping through the insulators. and adjustments needed because of near metal proximity. You may want to read about Antennas in the ARRL antenna Handbook. You can find them at the Library... Let me upload "Practical Antenna Handbook by Carr" to the files area here... Larry W8LM |

REPEATER-
We've been getting some carrier with what sounds noise on the repeater.. it is followed by a single beep- indicating it is local.. double beep is a real signal and going into the ALLSTAR system.
I am not hearing anything on the input here in Mulvane, I am 17 air miles from the repeater.? Since the last 3-4 days were quite windy, I don't know if it is? RFI from a EVERGY pole or HV line. .. or since it seems to last sometimes for 10 seconds or more, and is? something else. At the time of this writing , in Mulvane my WX station says ZERO wind.. Yet is is continuing.? I almost wonder if it is intentional, as if someone can generate the signal, then tires after a few hours. Sometimes it is ovbiously a week signal, other times quite strong. If someone is close to the VFW than my 17 miles and when it's active switch to the repeater input. 144.67 and see if it can be heard nearby. or at all... I am starting insulating and sheet rocking my addition this week and it's a 2 man job. So I really can't just take off 22 miles to the VFW - besides the VFW doesn't open to 3pm. Like with everything else Delays continue to plague me. My truck has been in the shop since August 5th. We finally have the right bumper tenatively arriving Tuesday.. Today I have to go with my contractor to Menards on Maise with my trailer to get 248 sticks of Harty board, and sheet rock. Lowes in derby does not have selection or prices found on the other side of town. That makes every trip a 2-3 hour venture. I do have a direction finding antenna but not the time, a it's intermittent.? If anyone hears something on the input let me know...Last year it seemed to be dew-frost? on the antenna.. fiberglass antennas are known for that. I believe those antennas are 10 years old now. they were epoxied when assembled to insure moisture proof ability. |

This is the END, Beautiful friend. This is the END; My only friend, the END.
Taking words from the 1960's group and The Doors Album.....
Drove past Derby Radio Shack.. There is a FOR SALE Sign on the Radio Shack sign at the street. So I swung in and tried to trade tonight's lotto ticket for the store.. NO DICE... I did get the skinny--- ?Radio Shack Derby is closing DECEMBER 16th.. A Saturday... The Building is for sale, Shawn and Mark are retiring!!! Now for the purpose of this posting- I think we- W0VFW Amateur Radio Group should give then a send off.. A "retirement party" either at the store or at the VFW... Mark, when I was President, was Awarded W0VFW Ham of the Year. He used to provide Radio Shack Gift Cards for a meeting raffle every month.. Especially with the $25 hand helds on Amazon,, and dollar store batteries, and every store selling phone cigarette lighter adapters, and USB cables. Time to retire Radio Shack- one of the last stores alive.. Mark has been in the business all his life. His father was district manager..? ? So--- DECEMBER 16th is the 3rd Saturday...isn't that next our lunch day???? What better way to combine them- a fund raiser with a retirement party for Shawn and Mark..? Even hot dogs- chili dogs, sloppy joes, mac & cheese... cake and cookies.. type thing..? Or do we take Donuts to the store that Saturday morning?? ?? The board needs to address this and present something at the next meeting.? Perhaps -- food 1/2 price with W0VFW membership.. After all 8 dogs and 8 buns is like $2.50 even with inflation..that 32 cents our cost plus condiments and a paper plate.?? Invite the entire ham radio community. WE better get this advertised by NOV 1st..? Now the VFW people won't join the ham club but other hams coming to Shawn and Marks retirement will .. Larry W8LM ARRL Life Member- Licensed 57 years. |
